Thermal conductivity of khoa has been studied. The probe works on the principle of line heat source method. Thermal conductivity of milk of different concentration levels and of khoa having different moisture was measured between the temperature range of 10-90°C. The experimental results were statistically analyzed and an equation was developed to predict the thermal conductivity of khoa at different conditions. Significant effect of temperature and moisture was observed on thermal conductivity of khoa. Thermal conductivity increased linearly with increased in both temperature and moisture.

The effects of dilution of wood apple flesh and thermal treatments of flesh-water blends on the ease of pulping, pulp yield and the chemical characteristic of the extracted pulp were investigated. Extraction was difficult when added water was less than one part of flesh. Dilution increased the pulp yield and TSS (Total soluble solids) recovery, but lowered the content of TSS, acid and vitamin C in pulp. Pulp yield was decreased significantly with heating of fleshwater mix to 80°C. However, thermal application enhanced the TSS recovery and content of TSS and acid in pulp. Flesh to water ratio of 1:2 and heating of this mix to 100°C were found ideal for an easy extraction of pulp.

Temperature effect on dimerization constant for several rhodamine dyes in polyvinyl alcohol films is studied. Based on absorption measurements it is found that contrary to liquid solutions the dimerization constant in polyvinyl alcohol films depends only weakly on temperature over the range studied. This holds true for films heated before measurements above the glassy transition phase temperature. For unheated films, however, the dimerization constant decreases significantly with increasing temperature. It occurs also that the value of dimerization constant is usually distinctly higher in unheated films and it is close to that in heated films only at high temperatures. The dimer absorption spectra determined based on our software are also different in heated and unheated polymer films. These regularities are also reflected in the fluorescence spectra and fluorescence intensity decays of concentrated samples. The results described can be connected with the polymer film structure different in both phases.

Seventy five young women residing in the hostel and an equal number of dayscholars in the age group of 18 to 23 years were selected and their nutritional status were estimated through various anthropometrical test to detect this physical fitness. Results of the study revealed that the incidence of sub-clinical iron deficiency is high among young women (62 per cent) which adversely affects their physical fitness. As the diets of young women were deficient in both iron and energy, nutrition education may prove useful. Further, it is impracticable to supply medicinal iron for longer periods. So, iron fortification of selected foods of daily consumption is essential for adequate supply of iron to vulnerable groups who suffer from iron deficiency but remained undiagnosed due to absence of clinical symptoms.

J Polym Mater 1999, 16(4), 341-5.

Plastic recycling was carried out on the virgin HDPE, collected recycled HDPE material, and the mixture of both. Processing aids in terms of certain percentages of anti-oxidants and slipping agents were added to virgin HDPE and the 50/50 mixture of fresh HDPE and recycled HDPE material. The specific emphasis was placed on the thermooxidative degradation of material during processing cycle. The performance of resulting reprocessed plastics was monitored using Fourier transform infra-red (FTIR), differential scanning calorimeter (DSC), and study of mechanical properties. The results clearly reveal the rapid thermooxidative degradation of the 50/50 mixture of fresh and recycled HDPE material, which can be attributed to the antagonistic mixing effect of two materials and the early loss of added anti-oxidants and processing stabilizers. The better processing stability can be achieved by incorporating appropriate percentages of processing stabilizers in the polymer resin.

Labiatae family is universally considered as an important source of natural antioxidant. Methanolic extracts of 8 species of Labiatae were purified and their antioxidant activities were determined by Active Oxygen Method (AOM), Rancimat and Schaal oven methods in soybean oil and by AOM in hydrogenated vegetable oil. The effects of extracts conentration and also the combination of extracts and citric acid or α-T on soybean oil stability were studied. Rosemary extract was found to be very effective in stabilizing soybean and hydrogenated vegetable oils by all three methods of evaluation. However, results from extracts with intermediate antioxidant activity i.e. thyme, balm, serpollet, marjoram and T. pubescens differed from one method to the other and also type of substrate or oil. Spearmint and N. bracteata did not show any antioxidant activity in the tested oils at high temperatures. All plant extracts had negative synergism with α-T, but some showed positive effect with citric acid. The stability of soybean oil increased with increase in extracts concentration.

Package of practices has been standardized/developed for the analysis of organochloro pesticide residues (OCPR) in milk. Clean-up of OCPR over florisil column chromatography was carried out to yield fat free OCPR isolates from milk samples, having fat content not more than 8%. A thin layer spotting (TLS) method (detection limit; 0.01 ug) has been developed for the detection of total OCPR. This method simply involves careful loading of TLC alufoil with OCPR isolates, spraying with silver nitrate solution and exposing to UV light. The appearance of violet black spots confirmed the presence of OCPR. Further, the detection of individual OCPR above MRLS was achieved through TLC in cyclohexane system. Finally, an HPLC method was standardized for the identification and estimated of individual OCPR in milk.

Substitution of blackgram by soybeans increased the water requirement for batter preparation and decreased the final volume, final pH, viscosity and fermentation time of batter. However, acidity of batter remain unaltered. Protein, fat and ash contents of idli increased whereas carbohydrate content decreased on the substitution of black-gram by soybean. Substitution of blackgram by soybeans in idli batter also increased the bulk density, hardness, cohesiveness and gumminess of idli whereas springiness and chewiness decreased. Sensory evaluation of idli samples revealed that the substitution of black gram by soybeans to the extent of 30 per cent did not alter the overall acceptability of the product. However, the proportion of soybeans above 30 per cent level significantly (P<60>0.05) reduced the quality of idli.

J Fd Sci Technol 2000, 37(4), 415-8.

Study on the preparation of debittered kinnow juice concentrate of 72°B and optimization of different storage conditions was conducted. During storage of concentrate, physico-chemical and microbiological changes were recorded and these changes were minimum in the concentrate, which was stored at -18°C than that stored at 0°C and 37°C. For packing of concentrate, glass container was found better than HDPE container. Addition of SO₂ did not have much effect on physico-chemical characteristics of concentrate. However, it checked the growth of moulds and osmophilic yeasts. Though the concentrate packed with SO₂ had lower microbial counts, the concentrate stored without SO₂ was also microbiologically stable over 6 months of storage. Thus, the kinnow concentrate of 72°B packed in glass or HDPE container with or without SO₂ could be stored at -18°C without much changes in physico-chemical characteristics. The concentrate also had no sign of fermentation or off odour. However, for better retention of quality, the concentrate should be packed in glass container with 700 ppm SO₂ and stored at -18°C.

Treatment of mustard cake with 2% CuSO4 solution @ 50 ml/100 g (pH 6.6) reduced its total glucosinolate content from 127 to 79.07 μmol/g. Palatability of concentrate mixtures containing a similar level (30%) of untreated (T1) and treated mustard cake (T2) was assessed using two groups of crossbred (Alpine X Beetal) kids of uniform age (3 months) and body weight (12.0 kg). The palatability of concentrate mixture, adjudged by its intake within 60 min of offering and as total intake in 24 h, was significantly higher (P<60>0.05) in group T2 than in group T1 during an experimental feeding of 28 days. However, nutrient digestibility, feed efficiency and rumen fermentation pattern were similar in both the groups. In group T2, dietary glucosinolate and Cu were both excerted largely through faeces which showed the possibility of chelation of glucosinolate and Cu, though the Cu balance was also very high in this group. It was concluded that CuSO4 treatment of mustard cake reduced its glucosinolate content and improved its palatability without any adverse affect on the performance of kids.

Coal gasification is an old and proven technology that is now attracting renewed interest and undergoing modernisation. All gasification processes can be categorised into 3 generic types, i.e. moving bed, fluidised bed and entrained bed, each having distinctive characteristics. The peculiar characteristics of Indian coals create complexities and limit the choices of gasification processes which have been discussed in the paper giving illustrative examples. Fluidised bed process followed by moving bed appear to be more suitable for high ash Indian coals. Entrained bed may be suitable when the coal is washed to reduce the ash content below 20%.

The voluminous production of flue-gases by Cast Iron Foundries damages the environment since it contains gases like SO2, CO2, CO, H2S which are poisonous. However, melting by coke-fired cupola does not obey the environmental regulations. The emission of the gases, suspended particles, dust and grit have not been found within the pollution control limits. Approximately 3 lakh people related to this industry in Agra have been affected by this directly or indirectly. Due to the closure of foundries, the Diesel Engines and Generator industry is also on the verge of closing. Therefore, it has become essential to develop a substitute of coke as fuel in foundries. Deals with the importance of an LDO fired rotary furnace for small scale foundries of Agra and the excess air, and preheating of the air before it enters into the combustion chamber. The experiments done on the rotary furnace show that one can have 40% to 50% of excess air at a preheat temperature of 200°C, while for some special grade castings such as Ductile Iron castings, one can have more preheat temperature and low percentage of excess air. Preheating also results in the reduction of the fuel consumption.

F and D values for the three enzymes were F^19.0100 = 4.9 and D^17.0100 = 2.3, F^7.5100 = 4.5 and D^8.8100 = 3.5, and F6.00100 = 0.16 and D8.0100 = 0.14, respectively. It shows peroxidase to be the most heat resistant enzyme. Green cowpea pods should be blanched for periods equivalent to uncorrected F values at the blanching temperature. Considering possible variations in initial enzyme activity, a 2D process has been suggested.

J Fd Sci Technol 2000, 37(4), 373-9.

Effect of different extrusion temperatures (75, 80 and 85°C) and feed moisture (17, 20 and 23%) was assessed on the level of proximate principles, amino acids and minerals of faba bean (Vicia faba L.) flour upon extrusion cooking. Crude proteins increased in all extrudates, maximum at 75°C and 20% feed moisture. Crude fibre too, was elevated, whilst fat was reduced. The levels of tryptophan and methionine were also affected. Calcium and phosphorus decreased whilst iron was remarkably increased. However, variations in both the extrusion temperature and feed moisture levels affected the magnitude of changes of all the biochemical parameters differentially.

J Fd Sci Technol 2000, 37(4), 384-7.

Experiments were conducted to study the effect of modified atmosphere packaging on low molecular weight carbohydrates of oyster mushrooms (Pleurotus ostreatus), during post-harvest storage at 5 and 15°C, using highly permeable micro-perforated oriented polypropylene (OPP) film and ordinary OPP film packages. Changes in sugar and sugar alcohol contents among different treatments were measured, using high performance liquid chromatography (HPLC) technique. Among free sugars, trehalose content was observed to be varying between pileus and stipe portion of the mushroom, in response to in-pack gaseous environment. Increases in pileus and stipe portions trehalose and total sugar content were observed for mushrooms packaged in micro-perforated film packages at both the storage temperatures of 5° and 15°C, while they reduced in ordinary OPP film packages and the reduction was observed to be more in stipes than pileus, indicating that low O₂ (0.4%) and high CO₂ (12 to 13%) observed in these packages had more adverse effect on stipe portion trehalose and total sugar content. Among sugar alcohols, only mannitol was found to be affected under low O₂ and high CO₂ conditions, prevailing in ordinary OPP film packages at both the storage temperatures.

Dietary survey was conducted on 65 farm families comprising of 343 individuals to assess the food consumption of hill migrants in Nainital Tarai region. In this population 54.4 per cent farm families were living below poverty line. In their food, the quantity per consumption unit of cereals (443 g), sugar (41 g) and vegetables other than leafy ones was adequate. But the quantity of pulses (34 g), milk (113 ml), fats and oils (18 g) was inadequate. The consumption of leafy vegetables was negligible. There was no consumption of animal products like meat, fish or eggs. The total energy intake was inadequate (2075-2190 Kcal) compared to Recommended Dietary Intake (2425 kcal) for Indians. In all the families, around 70 percent calorie intake was through cereals, namely rice and wheat. Protein level was more or less adequate (60 g) but its cheif source was cereal, and thus, quality of protein was poor. The intake of iron (40 mg) and thiamin (1.6 mg) was on positive side whereas that of vitamin A, riboflavin, niacin and ascorbic acid was on negative side. The deficiency was most acute for vitamin A (172 μg) and ascorbic acid (3 mg) in the farm families of landless labourers.

Low grade phosphate mineral has been investigated as a possible adsorbent for removing heavy metal ions such as Cu+2 from aqueous solutions. The effects of initial concentration of copper ion, contact time, temperature, particle size of adsorbent, and adsorbent dose were studied by equilibrating batchwise different amounts of low grade phosphate mineral with aqueous solutions of differnt concentrations of copper. Rate of removal of copper increases with time upto 30 min and thereafter it reaches equilibrium. Removal of copper is adversely affected by increase in initial concentration of copper and increase in particle size of adsorbent. The Freundlich and Langmuir adsorption isotherms were used to represent the experimental data of adsorption. Overall process of adsorption is spontaneous and exothermic in nature and follows first order kinetics.

Four soybean varietes were used to study the quality characteristics of paneer. The protein contents of varieties were significantly correlated with those of soy milk and paneer. The results showed that protein content of `Pooja' (39.46%) yielded higher amounts of total solids (6.05%) and soy paneer (179.00%). The textural qualities of soy paneer indicated that increased protein content contributed to higher paneer hardness (45.50 N). However, fat content did not have any effect on it. Soy paneer prepared from variety `Poja' was rated to be organoleptically superior, when compared to the paneer prepared from other varieties.

Milled rice of different degrees of polish (0 to 11.35) were stored in polythene bags and gunny bags for a period of 6 months (181 days) under ambient condition in a room. The changes in milling yield and head yield were determined at the end of each month for 0 to 11.35% degree of polish. The ANOVA indicated that the differences in the milling yields of milled rice stored in polythene bags were found insignificant at both 5% and 1% levels of significance. The head yield milled rice stored in polythene and gunny bags varied significantly at 1% and 5% levels of significance. A mathematical equation was developed to correlate head yield with storage period

Original aroma compounds present in the cardamom were isolated by Amberlite XAD-2 column chromatography from fresh green cardamom and termed as OFFC (Original flavour of fresh cardamom), distilling fresh green cardamom DOFC (Distilled oil of fresh cardamom) and distilling commercial cardamom DOCC (Distilled oil of commercial cardamom). They were analysed by HRGC and GC-MS techniques. The major compounds did not show much variations in these samples viz., 1.8 cineole and α-terpinyl acetate. Many sesquiterpene hydrocarbons were found to be present in the DOFC and not in OFFC. However, there were marked differences in the contents of other components. It was also observed that some new compounds were present in the oil of cardamom

J Fd Sci Technol 2000, 37(4), 394-9.

Various flour mixtures utilizing wheat, soy and defatted sesame flours in proportions of 70:20:10, 60:20:20,50:30:20 and 0:50:50 were prepared and subjected to chemical and nutritional evaluation. The protein contents of these flour mixtures were 20.12, 24.64, 26.30 and 48.95%, respectively. All these flour mixtures presented a balanced essential amino acid composition, when compared with that of FAO reference protein. The protein efficiency ratio values of these mixtures ranged from 2.19 to 2.46, while that of casein was 2.65. Several products prepared from these mixtures such as cookies, macaroni and burger poresented high protein concentrations of 10.96 to 18.74, 18.10 and 22.59%, respectively. Results of sensory evaluation of the products revealed a reasonable acceptance for macaroni. good acceptance for cookies and an excellent acceptance for soy-sesame burgers. It was concluded that these cheap vegetable protein sources in the preparation of popular foods could serve as an alternative to alleviate chronic protein malnutrition in underdeveloped and developing countries.

Eco-criteria have forced leather industry for re-looking at the increased use of organic materials. With a view to exploit the benefits of the vegetable tanning materials and to couple with a suitable organic material for overcoming the inherent shortcomings of vegetable tanning materials, studies were undertaken. Acrylic treatment followed by vegetable tanning produced leathers of higher hydrothermal stability. Hence studies were undertaken on vegetable - acrylic combination tannages to prove the versatility of the system. It was shown that leathers tanned by the new combination system could be coverted into medium soft upper leathers, as well as soft velvety suede leathers of rich shades. The finished leathers possessed good strength and light fastness properties.

Indian chem Engr 2000, 42(2), 78-83.

One of the major areas of application of monoclonal antibodies (MAb) is in the development of immunosorption-based artificial organ support devices. To offset the currently limited therapeutic applications of such devices in developing countries, higher production efficiency of the antibodies is needed. Getting higher yields of these antibodies is a major current issue in the area and of the various approaches of rapid development of high-density culture. L-lysine has been observed to be the most effective in viable (<62>95%) cellular expansion in vitro (from 10⁴ cells/ml to 10⁹ cells/ml) in 48 hrs., in sharp contrast to the current best of 2-3 weeks. Although this was attended by a parallel increase in the Ab titre, variability in molecular species in prolonged culture was striking with the appearance of a high molecular weight species (clumped?) of lgG with reported anticomplimentary activity in vivo.
