Palm (Elaeis guineensis Jacq). kernel is a tropical economic crop with high oil yield of about 47%. A study was carried out to establish the degree of influence of moisture content, duration and temperature of roasting on oil expression from this crop using the screw press. Effects of these parameters were used to develop model equations, optimise oil yield and the quality. A factorial experimental design was used. Expressed oil was recorded as percentage oil yield while free fatty acid, oil impurity and colour were used as indicators for determining oil quality. Data were analysed, employing multiple regression technique to generate mathematical models. Oil yield was maximized while free fatty acid, colour and impurities were kept at acceptable level. The optimum moisture content, duration of roasting and temperature of roasting were 3.1% wb, 4.5 min and 113.0°C . These combinations resulted in 44.9% oil yield, 1.3% (lauric) free fatty acid, 0.1% oil impurity and 7.0 Lovibond unit yellow.

J Fd Sci Technol 2007, 44(2), 216-9.
The cherry tomato (Lycopersicon esculentum) cv. 'Cluster' was stored in plastic film with various O2 and CO2 permeabilities at 5 ± 1 °C temperature and 90+5% relative humidity (RH). Cherry tomato was given hot water treatment (HWT) (54 °C, 5 min) before storage. Physico-chemical changes were recorded on 0, 7, 14, 21 and 28 days of storage. Weight loss was higher in tomato stored under normal atmosphere (NA) compared to modified atmosphere packaging (MAP). Initial total soluble solids of 4.4% increased to 9.4% in without HWT (WHWT)+NA. Initial firmness was 27.5 N. It was measured as 7.8 N in HWT+NA and 2.9 N in WHWT+NA at the end of storage. The acidity and ascorbic acid contents of tomatoes decreased during storage. The highest values were recorded at the end of storage from the fruit stored under HWT+50μ PE (polyethylene). Between HWT and WHWT treatments the levels of lycopene and βC-carotene contents differed significantly. Changes in fruit colour at the end of storage proceeded more slowly in the treated fruit. HWT+50μ PE gave the best result at the end of 28-day storage with respect to the parameters evaluated.

Sweet pepper (Capsicum annum. L) slices of 4 mm thick were dipped in 5, 10, and 15% salt solutions along with 40, 50, 60% sugar and 0.1% sodium metabisulphite at room temperature for 5, 10, 15, 20, 30, 40, 60, 80, 90, and 120 min. A sample to solution ratio of 1:5 and a constant agitation were used. The moisture loss from and the solid gain by sweet pepper increased non-linearly with the duration of osmosis at all salt and sugar concentrations, and both were higher in the initial period of osmosis than at later period. Sweet peppers were dipped in predetermined cut-off time in solution at 50, 60 and 70°C and then air dried in a fluidized-bed dryer. Osmotic dehydration prior to fluidized bed drying improved the organoleptic characteristics of sweet pepper slices in both dried and rehydrated forms.

J Indian Chem Soc 2007, 84(11), 1148-52.
The ground water in arsenic infested zone, West Bengal, India is characterised by high iron, arsenic, calcium, magnesium and bi-carbonate with low chloride and sulphate. The pH is generally greater than 7. In this pH medium, iron tends to precipitate as hydroxide and arsenic may also co-precipitate with ferric hydroxide. Addition of hydrochloric acid is necessary to dissolve all iron, prior to arsenic analysis by flow injection analysis system - atomic absorption spectrometric method. Addition of sufficient KI in HCl medium is necessary to reduce all As5+ to As3+ state before analysis. The average practical detection limit of the FIAS-AAS method is 0.035 μg/L. The method itself is highly sensitive and sensitivity is 0.07 μg/L which is far better than many other methods such as flame atomic absorption, hydrie generation atomic absorption spectrometric method and from the conventional spectrophotometric method. Shallow tubewell or well shows the highest peak in the bar graph.

Survey was carried out to study the quantity of consumption of coloured foods by the school children. A total of 210 high school children were selected belonging to age group 13-15 years. A total of 35 food products were analyzed for the presence of permitted and non-permitted colours. The results of the study revealed that, consumption of sweet meats were in the range of 22.5-210 g. The mean intake of laddu was more i.e. 96 g because the children consumed 3-4 laddus at a time. The intake of bakery products varied between 45-55 g. Confectioneries were consumed in the range of 3.8-80 g in the form of sugar candies, cotton candy, lolly pop, jeera peppermint, bubble gum, jujups, sugar jelly etc. Ice-candies were consumed by majority of the children in the range of 50-110 ml. The mean intake of various (permitted and non-permitted) colours was found to be in the range of 0.38-45.42 ppm. The mean intake of colour was high in flavoured milk (45.42 ppm). The intake of non-permitted colours was high in savouries such as gobi manchurian, chicken kabab, fish fry which was in the range of 24.92-39.90 ppm. Similarly, the intake of permitted colours was high in beverages which were in the range of 0.83-45.42 ppm. Observations of the study revealed that the consumption of non-permitted colours was found to be in the range of 0.04-39.90 ppm. Children are mostly attracted towards the coloured foods and are more prone to chemical insults than the adults. Hence, education and awareness programmes are needed especially for children to avoid health risks due to consumption of coloured foods.

Scheme for the real-time inferencing of solution concentration of polyethylene in xylene has been developed from cloud point and liquid-solid equilibrium measurements. An experimental study of the non-isothermal crystallisation behaviour of different weight fractions of polyethylene in xylene solution under variable colling rates was conducted. An indigenously developed microprocessor interfaced light determining resistance (LDR)-based sensing technique has been used to monitor the resistance offered by the system to the passage of light as function of time amd temperature. Cloud points for different weight fractions of polyethylene under study were identified using the LDR sensor. Repeated dissolution and crystallisation experiments were carried out non-isothermally under variable cooling rates at temperatures below the cloud points for each of the polyethylene weight fractions. The different crystallisation behaviour, as revealed by the LDR sensor readings, was analysed. The proposed real-time inferential scheme is based on an artificial neural network (ANN)-based predictor and a recursive least squares (RLS)-based updating algorithm. The ANN-based predictor describes the functionality of polyethylene concentration with the crystallisation run, solution temperature and LDR sensor readings, while the RLS algorithm is used to update ANN predictions by suitably incorporating the experimental measurements. Predictions of solution concentration obtained from the developed inferential scheme, during real-time experiments in presence of uncertainties, were found to be in good agreement with the experimental observations.

Physico-chemical, thermal, morphological and rheological properties of acid modified starches prepared by treating starch separated from 5 rice cullivars with 2.2 M HCl at 30°C for 24 h were studied. Amylose content, solubility, swelling power and intrinsic viscosity [η] were determined. Pasting properties of acid modified starches were measured using rapid viscoanalyser (RVA). Textural properties of acid modified starches (37.5% conc.) cooked in RVA were also measured using Instron universal testing machine. Amylose content, swelling power and solubility of native starches were in the range of 7.8-18.9%, 14.4-18.0% and 13.0-16.6 g/g, respectively. Upon acid modification, amylose content (5.0-14.1%) and swelling power (0.7-3.4 g/g) decreased while solubility (64.9-83.1%) increased in all starches. Acid modification caused a decrease in onset temperature and enthalpy of gelatinization and an increase in conclusion temperature of all the starches measured using differential scanning calorimeter (DSC). Intrinsic viscosity [η] of acid modified starches varied between 11.8 and 17.3 ml/g. The frequency sweep rheological evaluation of acid modified starch dispersions made in DMSO/distilled water was done with Fluids spectrometer. G' and G" intersects at the middle of the frequency range studied indicating a tendency for more sol-like behaviour at higher frequencies. Results revealed that acid modified starch from different rice cultivars under similar conditions resulted into starches, which differed significantly in their functional properties and hence differed in their suitability for different applications.

Increased use of synthetic pyrethroids in agricultural and pest control practices has resulted in increased pyrethroid residues in freshwater and marine sediments. The offsite movement of these compounds into surface waters is of concern. Pyrethroids have high acute toxicity to a broad spectrum of aquatic organisms and thus it is imperative to understand the ecotoxicological implication of synthetic pyrethroids in water sediments and its susceptibility to benthic dwelling fishes. This study would decipher the impact of the third generation Type II pyrethroid lambda - cyhalothrin which is liphophilic, hydrophobic in nature with greater environmental persistence and increased toxicity due its chemical structural modification in specific to benthic dwelling catfish Clarias batrachus.

Addition of GM had definite improvement in glycolysis (1.37-1.39% LA), proteolysis (8.9-11.2% soluble protein) and lipolysis (16.0-43.2 μ.eq FFA/g) of cheddar cheese as compared to the respective values of 1.20% LA, 8.3% soluble protein, and 12.2 μ.eq FFA/g of control cheese, while ME had positive impact on proteolysis (10.8% soluble protein) and lipolysis (36.8 μ.eq FFA/g). The proteolysis could be advanced by 2 months through addition of GM or ME while lipolysis could be advanced by 2-4 months. Addition of both GM and ME had synergistic effect on the proteolysis and lipolysis during ripening. GM had definite stimulatory effect on the growth of starter culture (9.0 log cfu/g) and lactobacilli (6.6-6.8 log cfu/g) in BMCC. The samples containing ME showed higher total viable count (8.9 log cfu/g) and lactobacilli count (6.9 log cfu/g) throughout the ripening period. Yeast and mold count and spore count were unaffected by addition of GM or ME or both and did not follow any distinct growth pattern during ripening. Coliform count, on the other hand. decreased with the progress of storage in all the samples. Depending on the availability, addition of GM or ME or both is recommended to accelerate the biochemical and microbiological changes during ripening of BMCC.

Low-fat ice cream (LFIC) was prepared in an 'ice and salt' type motor driven freezer using whey protein concentrate (WPC) as a fat replacer. The basic ice cream mix (control) was formulated to contain 4.5 % milk fat 13.0% milk solids-not fat (MSNF), 15.0% sucrose, 0.2% sodium alginate and 0.2% glycerol monostearate with a total solids content of 32.9%. Vanilla flavoured ice cream was prepared by replacing MSNF with WPC at 3 different levels Wl (1% WPC and 12% MSNF), W2 (1.25% WPC and 1 1.75% MSNF) and W3 (1.5% MSNF and 1 1.5% MSNF) by weight of the finished frozen product mixes. Addition of WPC in the LFIC resulted in a significant increase in protein content. However, it did not show any significant influence on pH and acidity. It increased viscosity and whipping ability of the mixes. LFIC manufactured using WPC resulted in increased overrun, melting resistance and decreased firmness of hardened product. The ice cream containing 1.25% WPC recorded better sensory scores of colour and appearance, flavour, body and texture, melting quality and overall acceptability compared to all the other samples. Sensorily, the order of preference was: W2

Non-insulin-dependent or type 2 diabetes mellitus is on the rise in India particularly in the affluent urban and rural population. The exact cause is unknown. Malnutrition, defective intake of essential fatty acids and reduced intake of fibres are found in Indian diet, particularly rural Indian diet and the dietary factors may be one of the causes leading to increased incidence of the disease. Dietary fibers reduce blood glucose and cholesterol levels. Resistant starches behave as dietary fiber. As rice is the staple food in Indian villages, to increase the fibre consumption, a special variety of rice is processed which contains more of resistant starch. The high protein efficiency ratio (PER) in rice is presumably due to the balance of essential amino acids in rice protein. This high resistant starch containing rice was fed to diabetic patients for three months and effects observed. Results showed that total cholesterol, fasting blood sugar, low-density lipoprotein cholesterol were reduced while other parameters showed no significant changes.

J Spices aromatic Crop 2007, 16(1), 31-7.
Experiments were conducted at Myladumpara (Kerala) to study the effect of storing fresh vanilla (Vanilla planifolia) beans before killing, killing temperature and duration of killing and further curing on quality parameters. The study indicated that storing of fresh beans for a maximum of 3 days after harvest and before killing is advisable and the vanillin content of such beans was the highest (2.51%) when compared to longer duration of storage. Killing of beans in hot water maintained at 65øC for 3 min or at 63øC for 5 min was on par. Immediate wrapping of killed beans with woollen cloth and storing in sweating box was the ideal method for obtaining optimum weight and vanillin content of beans. A higher percentage of beans (71 to 84) became ready for conditioning within 15 days of slow drying by this method. Interactions of killing temperature and exposing beans either directly or the next day as well as killing temperature and duration of killing were significant.

J appl Anim Res 2007, 32(2), 125-31.
In order to determine the highest efficiency of tuna oil (TO) supplementation, 48 barrows and 48 gilts fed on diets containing 0 or 20 g TO /kg diet were fattened either to 90, 100 or 110 kg live weight (2x2x3-factorial design). Variables describing water-holding capacity and texture of the M. longissimus dorsi were generally not influenced by TO as such. With one exception in shear force, no significant interactions among experimental factors were found. Incorporation of highly unsaturated n-3 fatty acids increased with TO supplementation, but this at the cost of fat shelf life. The n-3 fatty acids were reduced in proportion with increasing slaughter weight. In contrast, gender differences in poly unsaturated fatty acids found in unsupplemented pigs (higher in gilts), were balanced by TO supplementation. In conclusion, TO-fed pigs should be slaughtered early, while there is no need to differentiate for gender.

Experiment was conducted with two varieties of Okra viz. Pusa A-4 and Prabhani Kranti during summer, 1997 to study the storage behavior of Okra under different temperature (storage) conditions. The pods of the varieties were harvested at maximum edible stage of maturity i.e. on 7th day of anthesis. The pods kept in cool store required least force 9.28 N, 9.29 N and 9.72 N to puncture the pericarp on 2nd, 8th and 12th, respectively. This was followed by those stored in cool chamber that was 9.29 N and 9.67 N on day 2nd and 8th, respectively. Varietal difference was significant on day 8th and 12th in which Pusa A-4 packaged in ventilated polyethylene bags required significantly less force (9.22 N and 9.48 N. respectively) to puncture. The variety Pusa A-4 had significantly less dry matter content than Prabhani Kranti on day 2nd, 8th and 12th. On day 12, packaged pods had significantly lower matter than unpacked ones. The pods kepts in cool store showed significantly less crude fibre content (10.82%), followed by cool chamber (12.17%) and room temperature (12.84%), respectively on day 2nd. Similar trends were observed on day 8 and 12. The variety Pusa A-4 had lower crude fibre content on day 2, 8 and 12. i.e. 11.57 %, 11.62 % l1.16 % respectively. One day 2. 8 and 12, pods which were stored without any packaging had higher TSS (3.58° B. 3.53° B and 3.55° B) than those stored with packaging (3.36° B. 3.45° B and 3.44° B). The variety Pusa A-4 had significantly higher TSS than Parbhani Kranti on all the days of observation.

Substitution reactions of eleven para- and ;meta-substituted anilines with benzenesulphonyl chloride in different mole fractions of benzene in 2-methylpropan-2-ol have been investigated conductometrically. The second order rate constants don't correlate either with pKa values of the anilines or with the Hammett's and its modified equations. The para-substituted anilines shows a satisfactory correlation with Charton's LDR equation and the results indicate the formation of an electron deficient transition state. The rate data correlate satisfactorily with macroscopic solvent parameters such as relative permittivity, εr, and polarity, ETN. Multiple correlation analysis of the rate data via Kamlet-Taft's solvatochromic parameters reveals that the solvent hydrogen bond donor property plays a dominant role in governing the reactivity.

Main and basic raw material for processing of food in India are the cereals, in which wheat being the most important one followed by rice, maize, rye, oats and barley. The important processed fruits include orange, apple, pineapple, mango and others. The most widely processed vegetables are potato, beans, cabbage and tomato. Sugar, a constituent of most of the foods on ' display and particularly of confectionary is derived from the sugarcane grown in India. It is also now derived from beetroot. Meat in India is used from domestic animals like cattle, sheep, pigs and chicken. The seas and lakes are still the main sources of fish but in recent years fish is being reared in hatcheries and ponds. Meat and fish products are preserved by refrigeration at all stages of processing, manufacture, and transport in India. The poultry sector of modern India has transformed from backyard rearing to commercially organized, scientific and fastest growing sector among the livestock economy in the country. A silent revolution has been taking place in the last 4 decades in the poultry sector to take India to a mark on the poultry map of the world. Baking is the basic technology used for most cereal based food products. Irradiation is one of the latest technologies used in food processing. Till 1947 in India, consumption was limited to baby foods, canned foods, preserves and beverages. Slowly the food industry was dominated by rice hullers. chakkis and similar low technology units. Between 1947 and 1980, there was slow modernization of processing methods, hullers were replaced by shellers, chakkis for wheat were supplemented with flour mills, ghanis yield into expellerrs and others, which include solvent extraction plant, refineries, etc. This was followed by building up of equipment fabrication facility and development of indigenous packaging materials. Today, there is well established ready mix processing, fruit juice concentrate, tetra pack drink, extruded products, tertiary processed foods, ready-to-eat (RTE) extruded snacks, frozen RTE foods, retort pouched foods, warm and eat foods and health oriented foods. The recent history of brewing in India features the grading of licenses in 1970s. Currently there are at least 55 operational breweries in India. With respect to the sterilization of milk, the first ultra high temperature (UHT) plant was established in 1982. The soybean processing had its modest beginning in 1975. Today, the availability of soybean oil in the national oil pool is very high. The soybean processing industries are optimistic of fulfilling the twin objectives of meeting the edible oil and foreign exchange requirements of the country. Currently there are different categories of convenient foods viz. RTE foods, ready-to-drink/ready-to-serve fruits and vegetable based processed foods, ready-to-use foods, etc. The review also deals with aspects related to current status and future prospects with respect to organic milk, radiation processing of food, oscillating magnetic field, nano composite materials in food processing and biopolymers for food packaging and vaccum impregnation.

Soybean flour (SF), maize flour (MF) and their blends (10-90%) were evaluated for chemical composition and functional properties. The protein, fat, crude fiber and ash contents of the blends increased while carbohydrate content decreased with increasing the level of SF in the blend. The SF had higher water absorption capacity (WAC) but less oil absorption capacity (OAC) than MF. The WAC increased while OAC decreased with the addition of SF. The emulsion activity and stability of the blends were dependent on SF level in the blend. The foaming capacity and stability were high for MF. The protein content of the SF/MF cookies was between 13.2 and 36.8%, the values increased with higher levels of SF. There were no significant differences between the SF/MF and wheat flour (control) cookies in their physical properties. However, cookie weight decreased with higher levels of MF in the blend. The sensory ratings for colour and taste did not differ significantly among the cookie samples. However, cookies containing up to 50% MF were not significantly (p

Non-insulin-dependent or type 2 diabetes mellitus is on the rise in India particularly in the affluent urban and rural population. The exact cause is unknown. Malnutrition, defective intake of essential fatty acids and reduced intake of fibres are found in Indian diet, particularly rural Indian diet and the dietary factors may be one of the causes leading to increased incidence of the disease. Dietary fibers reduce blood glucose and cholesterol levels. Resistant starches behave as dietary fiber. As rice is the staple food in Indian villages, to increase the fibre consumption, a special variety of rice is processed which contains more of resistant starch. The high protein efficiency ratio (PER) in rice is presumably due to the balance of essential amino acids in rice protein. This high resistant starch containing rice was fed to diabetic patients for three months and effects observed. Results showed that total cholesterol, fasting blood sugar, low-density lipoprotein cholesterol were reduced while other parameters showed no significant changes.
