India today, more than ever before, needs to deploy technologies that are able to convert the 'waste' generated in the country to transportation fuels, as also to chemicals and materials. Aimed at reduction of petroleum crude-oil imports and reduction of green house gas emissions, these technologies will need to be highly India specific due to the peculiar nature in which the wastes, e.g. agricultural waste and municipal waste, present themselves across our country. The need therefore transforms to a situation wherein we need the new generation biofuel technologies to be 'made in India' for a 'swachh bharat' and in a way that adds value to the waste and hence becomes a path to generation of new enterprises in line with the 'start-up India' concept. It is however important, that the country is careful in making a judicious choice of technologies that are truly sustainable and products that are truly 'green'.

Indian J Dairy Sci 2016, 69(1), 1-7.
There are many varieties of cheese with differing characteristics, appeal and associated uses. Cream cheese is one such product which has potential of gaining popularity among the Indian consumers. Cream cheese is a soft, mild, rich, unripened cheese and is a creamy white, slightly acidic tasting product with a diacetyl flavor. It is usually manufactured by the coagulation of cream or mixture of milk and cream by acidification with starter culture Fatcontent plays an important role in physico-chemical, senssory and also the textural characteristics of cheese. Hence, for development of technology for Processed cream cheese based (PCCB) spread manufacture, different levels of fat in milk (2, 4 and 6%) were studied so that an optimum level yielding best organoleptic characteristics in final product could be selected. The better quality product was made from milk standardized to 4 per cent of cheese curd at the time of mixing in Stephan kettle. Final cost for production of 1 kg PCCB spread was computed Rs. 28.47. Based on the economic as well as sensory quality obtained, a level of 4 per cent fat for standardization of cheese milk has been selected.

Air pollutants emission from various source categories can be quantified through mass balance (receptor model) techniques, multivariate data analysis and dispersion model. The composition of particulate matter from various emission points (emission inventory) and the massive analysis of the composition in the collected samples from various locations (receptor) are used to estimate quantitative source contribution through receptor models. In dispersion model, on the other hand the emission rates (μg/m3) from various sources together with particle size, stack height, topography, meteorological conditions (temperature, humidity, wind speed and directions, etc.) will affect the pollutant concentration at a point or in a region. The parameters used in dispersion model are not considering in receptor models but have been affecting indirectly as difference concentration at various receptor locations. These differences are attributed and possible erroneous results can be viewed through coupled receptor-dispersion model analysis. The current research work proposed a coupled receptor-dispersion model to reduce the difference between predicted concentrations through optimized wind velocity used in dispersion model. The converged wind velocities for various error percentages (10%, 40%, 60% and 80%) in receptor concentration have been obtained with corresponding increase in the error. The proposed combined approaches help to reconcile the differences arise when the two models used in an individual mode.

Indian J Dairy Sci 2016, 69(1), 17-23.
Frozen desserts like ice cream are valued for their pleasing flavour, cooling and refreshing effects. Ginger (Zingiber officinale) is valued for its medicinal and therapeutic properties. In present investigation, ginger - a natural herb, was used as a flavouring agent in ice cream. A basic ice cream mix having 12% fat, 11% solid not fat, 15% sucrose, 0.4% sodium alginate and 0.1% glycerol monostearate was prepared. Ginger juice was incorporated at levels of 0, 1, 2, 3, 4 and 5% w/w of ice cream mix. After experimentation, it was found that the gradual increase of ginger juice caused increase in freezing time with decrease in freezing point depression. The ginger juice also brought significant variations in overrun and melting characteristics. However, the variations were within a close range which ultimately did not impart adverse effect on sensory quality of ginger ice cream. The ice cream made with 4% ginger juice comprising of 11.53% fat and 3.89% protein with 43% overrun was found to be most acceptable.

Antioxidants are substances that are able to prevent or inhibit oxidation processes in human body as well as in food products. Oxidation reactions can produce free radicals, which start chain reactions that damage cells. Antioxidants terminate these chain reactions by removing free radical intermediates and inhibit other oxidation reactions by being oxidized it selves. The protection of foods from oxygen is the basic principle upon which antioxidant protective technologies are based. Both synthetic as well as natural antioxidants are using in food industry but the application of synthetics has been reassessed due to its potential carcinogenic effects. Research is being focused on vegetable materials which are a rich source of antioxidant compounds. Various antioxidant compounds have been isolated, many of them being polyphenols. Direct relationship exists between the total phenolic contents and the antioxidant activity in fruits and vegetables. The entire tissue of fruits and vegetables are rich in bio-active compounds and in most cases the waste by-products can present similar or even higher contents of antioxidant compounds. The waste materials such as peels, seeds and stones produced from the fruit and vegetable processing unit can be successfully used as a source of phytochemicals and antioxidants. Different antioxidant sources, their mode of action, application in food industry and antioxidant sources, their mode of action, application in food industry and antioxidant activities of banana peel, watermelon peel, potato peel and cucumber peel are reviewed in this paper.

Asian J biochem pharm Res 2015, 5(3), 182-92.
Persimmon (Diospyros kaki L.) is a subtropical fruit due to which it has short postharvest life. Authors have investigated the effect of gum arabic, guar gum and chitosan based edible coatings blended with suitable plasticizer on the postharvest quality and shelf life of persimmon fruits. Fruits were dipped in different edible coating solution for 1 minute, followed by air drying at room temperature and stored at 25 ± 2°C and 50 ± 5% RH for 15 days. Changes in shelf life, weight loss, firmness, total antioxidant activity, total phenol contents, color and sensory evaluation were evaluated. The results showed that fruit shelf life was significantly increased by edible coating treatment. Application of 1.0% guar gum, 1 and 1.5% chitosan delayed weight loss (5.4% and 4.5% lower than non-coated fruits respectively), colour development and retained greater total antioxidant activity, total phenolic compounds and firmness compared to the control (non-coated) treatments. No significant differences were observed in fruit shelf life between the two concentrations of gum arabic coating. These results demonstrated that postharvest chitosan and guar gum application has potential to extend shelf life and maintain quality of harvested 'Hachiya' persimmon fruit. The coating of guar gum and chitosan displayed increased shelf life by 20 days. The sensory evaluation of coated persimmon fruit for taste, colour, texture and overall acceptability further confirmed the findings.

Fruits and vegetables are highly perishable commodities thus in order to limit the post-harvest changes in a commodity, a environmental friendly technology i.e. edible coating can be applied. In this, a commodity is enrobed using natural polymers. This technology offers various advantages like maintaining food quality and increasing shelf life by delaying the ripening process, color changes, maintaining texture, reducing weight loss and decay. Now, this Coating can be done in various ways like dipping the product into, or by spraying it or brushing with a solution containing film ingredients. It is a simple technology which gives a clear and opaque view which is preferred by the consumer and hence easily acceptable. Apart from this by developing edible films and coatings with antimicrobial activity, by incorporating antimicrobial components as additives for edible film formulation can be of great use.

Raw feather is a favorable material for processing into feed rich in proteins convenient for nutrition of certain animals species. Since proteins of raw feathers are poorly digested, the improved digestibility of proteins may be achieved by hydrothermal processing of raw feathers. In this study the effect of water quantity at hydrothermal feathers treatment in industrial processing conditions on the nutritive value of hydrolysed feather meal was investigated. By these technological conditions in vitro digestibility of protein in hydrolysed feather meal was significantly increased in relation to digestibility of raw feathers. Hydrolysis contributes to the decrease of protein nitrogen content, whereas contents of non-protein nitrogen, ammonia and α-amino nitrogen were increased. Significant decrease of cystine content in the proteins of hydrolysates was noticed: 3.81, 4.07 and 4.21 g/100 g protein, depending on the technological treatments with the moisture content in raw feathers of 50%, 60% and 68%, respectively.

Lincoln during mechnical drying. J appl nat Sci 2016, 8(2), 1049-52.
An experiment was conducted to standardize the predrying treatments with minimum loss to physicochemical characteristics of green peas (Pisum sativum L.) cv. Lincoln during drying process. In this study, moisture content (73%), TSS (15°B), chlorophyll content (28mg/100g) and ascorbic acid (54mg/100g) were recorded in green peas. Different predrying treatments used in this study for quality preservation of peas were T0, T1 and T2. From this study, it was concluded that Na2CO3, NaCl and sugars were responsible for the preservation of green color/ chlorophyll in peas during drying. On the basis of sensory evaluation T2 was found best among all because maximum green color was retained in this treatment. Therefore, it was further selected for physico-chemical analysis After drying there was decrease in moisture content (4%), chlorophyll content (17mg/100g) and ascorbic acid content (37.6mg /100g) while increase in TSS (22°B), reducing sugars (8.3%) and total sugars (20%) of peas. A rehydration ratio of 3:1 was observed for this treatment. This is a low cost technology for preservation of quality of peas. Dried peas can further be utilized for the preparation of various value added instant products round the year.

Curr Sci 2016, 110(3), 353-62.
In this article, the effect of hydrophobic coated and uncoated surfaces on the corrosion resistance, tribological property, and surface morphology and nanomechanical properties is presented. A hierarchical surface (micro/nano) was prepared by ultra shot penning of 316L stainless steel at 20 kHz. Chemical vapour deposition technique was used for deposition of the coating, and coating thickness of 0.5 μm was obtained. A maximum hardness of 6.7 and 6.32 GPa was exhibited by the sandblasted (SB), annealed (SBA) and coated (SBAT) samples respectively. The beneficial effect of annealing and surface roughness was clearly indicated by the sandblasted, annealed and coated specimens. They showed the highest value of reduced modulus maximum resistance to scratch tests and a high adhesion as indicated by scratch path profiles. The lowest corrosion rates were obtained by SBAT specimens (1.32 mpy) in 3.5 wt% NaCl.

Experiment was conducted to standardize the methodology for preparation of jamun fruit leather. The fruits were harvested at optimum maturity and after thorough sorting and proper washing, were used for hot extraction of pulp. Additives like sugar was added to the pulp in different proportions, whereas pectin and citric acid were kept constant. However, in control samples, no citric acid, sugar or pectin were added. The mixtures thus formulated with varying sugar were dried in mechanical dehydrator. Dried fruit leather sheets were cut into rectangular shapes and wrapped in cling film followed by packing in aluminium pouches. Packaged samples were stored under ambient conditions and kept for 6 months and analyzed periodically for changes in quality. During 6 months of storage, the moisture content increased from 18.43 to 19.15 along with slight losses in titratable acidity, ascorbic acid, total soluble solids, anthocyanins, tannins and mineral contents. Results of the sensory evaluation indicated that a very good quality fruit bar can be prepared by using pulp + 55% sugar +0.3% pectin. Further, the products were stable up to 6 months during storage under ambient conditions.

Dairy wastewater when released from the industry is highly rich in organic matter, suspended solids, oil and grease, fats, nitrogen, phosphorous and calcium. After disposal it may cause water as well as land eutrophication and can block soil pores thus resulting in reduced levels of soil infiltration. When send to the treatment units this dairy wastewater also results in crystalline deposits. Dairy wastewater is classified as nutrient rich wastewater containing sufficient amount of nitrogen, phosphorous and calcium that can be separated or extracted by suitable methods. The extraction of these nutrients is done using a lab scale batch reactor of desired efficiency needful to justify this issue and find a solution to it. The process of extraction of nutrients is performed using a Mixed Suspension Mixed Product Removal Batch Reactor of suitable dimensions in the form of Magnesium Ammonium Phosphate and Hydroxyapatite. These nutrients being a slow released fertilizer will provide value to the crop production and land yield, further reducing BOD, COD and TSS of the wastewater making it safer to dispose. Dairy wastewater is taken from an industrial source which is firstly characterized, diluted and then fed into the reactor in the presence of suitable seed material resulting in formation of crystals. Experiments performed for the formation of Magnesium Ammonium Phosphate and Hydroxyapatite are separately carried out in different batches. The key focus of this project is to enhance the efficiency of dairy wastewater treatment units and prevent crystallization during treatment process.

The objective of this work was to optimize CI engine with WCO (waste cooking oil) biodiesel as fuel through experimental investigation through brake power, fuel economy and smoke emissions. Performance and discharge features were studied using the different WCOB blends and standard diesel. The result shows that the maximum BTE for WCOB 40 at maximum load is 34.48%, which is 2.9% more than diesel fuel. High BSFC noticed for higher percentage of WCO blends due to lower heating value, density and viscosity of the fuel. The exhaust gas temperature attained for diesel is 306°C at maximum load, whereas for WCOB20 and WCOB40 blends it is 278°C and 263°C. The HC emission for WCO blends increases with rise in load. WCOB20, WCOB60, WCOB80 and WCOB100 produce less HC emissions than WCOB40 and diesel. The CO emission of WCOB40 is closer to diesel, moderate at medium load and higher at part loads. CO2 emission for WCOB blend is lesser than diesel due to incomplete combustion and inadequate supply of oxygen at high load. The NOX emission for diesel and WCOB40 are 642 ppm and 428 ppm, respectively at part load. The smoke opacity features for diesel and WCOB100 are small and upper in the case of all other WCOB blends. From this study, it is clear that WCOB could replace the fossil fuel in the case of shortages in the near future.

Processes of separating oxygen in air and H2S in the acid gas feed using a membrane process are based on the relative permeability of components in the feed and are done due to the pressure difference between membrane sides. The mathematical modeling and simulations of the membrane separation processes is solved using EES software without the need for programming outside of the simulator. Passing flow through the membrane is considered counter current and the simulation is done according to the characteristics of hollow fibre membranes. In this study, using this simulator, the percentage of separating components (oxygen and H2S) of the air and sour gas in the two output flow of the membrane and effect of different parameters on the separation percentage of these components is reviewed. With increasing the feed flow (air and acid gas feed), oxygen and H2S concentration output of the membrane is decreased. However, concentrations of these components have direct correlation with the selectivity and membrane surface area. In addition, the effect of the feed pressure on the oxygen and H2S percentage output of the membrane is a function of the permeate pressure.

Rapid global warming has triggered global efforts to reduce concentration of the most contributing Green House Gas carbon dioxide (CO2). Carbon dioxide capture and storage (CCS) is considered a crucial strategy for meeting CO2 emission reduction targets. The selection of specific CO2 capture technology heavily depends on the type of CO2 generating plant and fuel used. Among the CO2 separation processes, adsorption is the most mature and commonly adopted due to its higher efficiency and lower cost. Operating conditions (temperature and pressure), CO2 selectivity and cyclic stability are the important parameters in selecting suitable adsorbent for the process. Many adsorbents have been developed and studied for their performance. Among the various adsorbents, Activated Carbon (AC) materials were found to have higher selectivity and cyclic stability. The adsorption process is very complex. Adsorption and desorption kinetics depend on pore size, pore charge, bed characteristics and flow regime. In this paper, simulation was carried out to study the rate of adsorption of the gas on ACs, and analyzed along with the unsteady heat transfer. A parametric analysis was carried out to study the effect of various crucial parameters like radius of bed, fluid temperature, and heat transfer coefficient (h) on the adsorption amount. The results are validated with literature data. The simulation results show that initial bed temperature, bed radius, and heat transfer coefficient play significant roles in the effectiveness of CO2 capture process.

The use of catalysed exchange of deuterium (D) between hydrogen (H) gas and liquid water using the bithermal hydrogen water (BHW) process is a promising and environment-friendly approach for the production of heavy water. However, the use of this approach is limited by the lack of a suitable catalyst that has good activity at high operating pressures required for practical applications. We report the development of hydrophobic platinum-doped carbon aerogel (PtCA) catalyst which shows good catalytic activity for H/D isotope exchange reactions at operating pressures up to 20 bar.

Due to increasing health awareness among consumers; food manufacturers, researchers and producers are aiming to develop functional foods with additional health benefits along with providing basic nutrition. Glycemic index of food directly affects the blood sugar level and caused fatal health problems such as diabetes and obesity. Glycemic index of a food is inversely related to its resistant starch content, hence, food nutritionists are looking out for incorporation of resistant starch as a functional ingredient in processed foods to increase its acceptability in terms of healthy alternative. Resistant starch is gaining attention as functional ingredient due to its unique physiochemical and functional properties. Incorporation of resistant starch (RS) in wide variety of products such as breads, cookies, muffins, pizza crust, tortillas, breakfast cereals and snack products are already being practiced. Production of RS at commercial level requires industrial inventions required to meet the growing demand of it as a functional ingredient.

Present study was conducted during the year 2014-15 at HCRI, Venkataramannagudem. The juices used in the study were those obtained from mango, grapes and pineapple blended in different proportions with jamun juice. These juice blends were utilized for the preparation of RTS and were evaluated for their quality throughout the acceptable period of storage. Colour, TSS, acidity, pH, reducing sugars, non-reducing sugars total sugars and overall acceptability were observed throughout the storage period. The optical density of the beverages, acidity, reducing sugars and total sugars increased continuously during storage period, while pH, non-reducing sugars decreased during the storage period. The decrease in organoleptic acceptability was due to the change in the composition of these parameters. The RTS prepared from 75% of jamun juice blended with 25% grape juice had highest overall acceptability among all the combinations. However, all these RTS beverages were acceptable up to 90 days of storage period.

Plants are sedentary living organisms performing vivid roles in life cycle from germination to reproduction. During this journey they encounter several distinct obstacles right from the exposure to various unsuitable climatic conditions, to unwanted attackers such as insects, pathogens or even the manmade chemicals. Though the plants are motionless and inactive in appearance often they wisely defend themselves. Majority of the insects depend on plants for their feeding, oviposition and sometimes whole survival itself. Plants when attacked by an insect or a pathogen, respond to resist the intrusion in its life and overcome it in several ways. Plant chemicals and hormones are important shielding molecules present in them that stimulate responses against herbivores. Plants utilize cost effective methods to administer its energy for either growth or defense against insect feeding. They defend themselves utilizing the plant variability of primary metabolites, secondary metabolites, alkaloids and plant enzymes that detoxify the reactive oxygen species. Thus they have either antinutritive or antidigestive effects that play a major role in inhibiting the invasion of insects. These mechanisms help plants defend themselves from feeding insect or animal attack and this area of research is gaining interest in scientific community off late.

This study was carried out in Kuinet (Chepkongi) Dam within Uasin-Gishu County, Kenya to assess primary productivity, nutrient levels and trophic status of the dam. Water samples were collected at four sampling stations (inflow, outflow and in the middle) of the dam monthly from November 2014 to January 2015. The samples were used to assess the chloropyhll-a, net primary productivity and the main physico-chemical variables. Phytoplankton was sampled using a phytoplankton net, identified and counted using an inverted electronic microscope. Canonical Correspondences Analyses was carried on to ascertain the correspondence relationships of the sampled parameters. The trophic status was calculated using the Carlson method considering the parameters: chloropyhll-a, Secchi Depth and Total Phosphorus. The phytoplankton community of Kuinet Dam is composed mainly of four families; Bacillariophyceae and Chlorophyceae families each had 11 species followed by Cyanophyceae with 5 species and Desmidiaceae with 3 species. The family Chlorophyceae dominated in abundance in all months. Net primary productivity ranged from 0.182±0.09 mgO2L-1d-1 in December to 0.299±0.13 mgO2L-1d-1 in November. Dissolved Oxygen, net primary productivity, Biological Oxygen Demand and temperature displayed similar trends during the three sampling months. Chlorophyceae had near correspondence with these three parameters than the others according to CCA. The trophic status of the Dam resulted both mesotrophic and eutrophic. From the study, we reject the HO hence the primary productivity of Kuinet dam favors aquaculture during the dry spell period. This in turn aids in facilitating the achievement of attaining the estimated potential production level of 2000 tons according the Uasin Gishu district environment action plan 2009-2013.

Many commercially available coatings that have been used are subject to combined effect of exposure to sunlight, changing humidity, and hot and cold cycles experienced during weathering. In many cases, due to lack of maintenance, the paint gets deteriorated, and starts to peel. Also, in the past, lead-based paint was used as a primer for the coating systems applied to these steel structures. Peeling lead-based paint will eventually fall into and contaminate the soil, and require extensive environmental cleanup. This paper will discuss a one-coat, high-build, lead-free, low VOC, self-priming coating that provides long term corrosion protection, low application costs, requires minimal surface preparation, and is easy to maintain. The system has been in use for over 50 years. Surface tolerant coatings, which can be applied over existing coatings with minimal surface preparation, provide a solution to these problems.

In recent years, an increasing interest concerning determination of nitrate levels in food products has been observed, essentially due to the potential reduction of nitrate to nitrite, which is known to cause adverse effects on human and animal health. The main goal of this study was measuring nitrate content of pear and apple derived canned products samples commercially available in Iran market in comparison on fresh fruits. Series analyses were performed with 80 canned pear samples produced at a large-scale local enterprise and purchased at recognized market and simultaneously fresh and 150 untreated samples was collected by going to the chosen areas of recognized farms in region of Fouman in Giulan province, Iran. In order to conduct a comparison between the content of nitrate in the studied samples, dry matter content was determined according to the association of office analytical chemists (AOAC). A ten gram sample of the prepared pear and apple was blended with 50ml distilled water in a home blender. The mixture was filtered and was passed through a glass 39 column fitted with a tape and filled with Activated alumina, in order to separate the color of Chlorophyll and get a transparent solution. The eluted solution by water filtered using 0.45um filter paper in order to eliminate the turbidity and get a clear solution. Nitrite concentration in pear samples was determined by spectrophotometric methods at a wavelength of 538 nm, after reducing nitrate to nitrite by using cadmium column. Nitrate content in analyzed fresh pears ranges between 63.22 - 143.76 mg/kg FW with an average of 101.743 mg/kg. The highest nitrate content was found in 'Abkhoj' (143.76 mg/kg) and the lowest content was in Amrud' genotypes (63.22 mg/kg FW). For canned pear the nitrate level ranges between 166.11 - 374.02 mg/kg with an average of 266.08 mg/kg. All the nitrate values in canned food samples are higher than those for corresponding fresh fruits. The nitrate levels in pear compotes are much higher than those for corresponding fruit due to the concentration process that takes place during pear processing. It is clear that the result of our study shows a variation in the nitrate and nitrite levels in the different genotypes samples and processing products.

Int J Fish aqua Stud 2016, 4(3), 61-7.
In the Senegalese upwelling ecosystem, Octopus vulgaris population shows high seasonal and interannual variability. Simple regression methods have been applied to investigate how octopus abundance is related to environmental change. However, the precision of such models is still unclear due to the non-linear character of the relationships. This work applied generalized additive model (GAM) to investigate ten years (1996-2005) variability of octopus recruitment in the Senegalese waters. The semi-parametric smooth function and Poisson distribution were used to build the models. The variables included in the models were sea surface temperature (SST and time (Month and Year). We show that GAM is more useful and relevant in investigating the complex relationships between octopus recruitment and SST at seasonal and interannual scales than classical regression techniques, by offering the best fits. We demonstrated that high octopus recruitment occurred at water temperature range between 17.5 and 18 °C.

017042 Darko S;Wireko-Manu F D;Mills-Robertson F C (Food Science and Technology Dep, Kwame Nkrumah Univ of Science and Technology, Kumasi, Ghana, Email: sophiadarko@yahoo.co.uk) : Enumerated bacteria on cooked food samples in some hotels in Kumasi in the Ashanti region of Ghana. Int J pure appl Sci Technol 2015, 31(2), 40-50.
Kumasi is the capital of the Ashanti Region of Ghana and also the second largest city. Kumasi was selected for this study because out of 27,000 cholera cases in Ghana, Kumasi was one of the most affected. Levels of microbial counts on some cooked food samples in some selected hotels in Kumasi, the Ashanti Region of Ghana were determined. The hotels were selected by simple random sampling and ranged from three star to budget. Serial dilution of each food was prepared in buffered peptone water inoculated onto Plate Count Agar (PCA) for total mesophilic count, MacConkey Agar (MCA) for total coliform count and Violet Red Bile Glucose Agar (VRBGA) for total enterobacteriaceae count. Growth was counted and the bacterial counts were expressed to Log10 cfu/g. The agar with the highest colony count for Hotel 01 was MacConkey and the food with the highest number of bacteria was fufu (7.0 Log10 cfu/g). Hotel 02 had PCA and MCA reporting the highest microbial count for beef in vegetable sauce (6.8 Log10 cfu/g). In Hotel 03 tossed salad and fried rice were too numerous to count (TNTC) for all the media used. Hotel 04 reported boiled plain rice to be the food with the highest (6.5 Log10 cfu/g) colony count on PCA. Vegetable sauce on MCA had the highest colony counts (7.2 Log10 cfu/g) for Hotel 05. Most of the colony counts were above the WHO acceptable levels of
