    The present investigation was carried out on "Effect of edible coatings and packaging method on shelf life of button mushroom (Agarius bisporus)". Three edible coating of three concentrations each were selected. Whey protein of 5, 10 and 15 per cent concentration levels; carboxy mehyl cellulose 1, 1.5 and 2 per cent concentration level and guar gum of 0.5, 1 and 1.5 per cent concentration levels. Coating was applied on mushrooms by dipping method for I min. then all coated and uncoated mushrooms were packed in four packaging methods open polyethylene bag; polyethylene bag sealed; vacuum packaging; nitrogen filled packaging under ambient condition. The quality of mushroom fruits was observed in terms of Physiological weight loss, firmness, Total Soluble Solids, acidity and decay loss. Mushrooms coated with whey protein of 5% concentration and stored in vacuum packaging and polyethylene bag stored in better condition upto second day. Physiological weight loss, firmness, TSS, acidity - 115 - and decay loss were respectively (3.77%, 9.87kg/CM2, 7.2oBrix, 0.49%, 38.33%) upto second day of storage. Mushrooms coated with CMC of 1% concentration and packed in vacuum packaging and polyethylene bag performed better upto third day. Physiological weight loss, firmness, TSS, acidity and decay loss were respectively (3.53%, 7.23kg/cm2, 6.00 ºBrix, 0.59% , 46.19%) upto third day of storage. Guar gum coated mushroom spoiled after first day of storage. Fresh mushrooms i.e. without any coating stored better in vacuum and polyethylene bag upto third day. Physiological weight loss, firmness, TSS, acidity and decay loss were respectively (4.41%, 7.76kg/cm2, 7.17ºBrix, 0.54%, 38.33%) upto second day of storage.

    Optimization of process parameters of soymilk and tofu production unit
    (CCSHAU, 2008) Indu; Jain, Surjeet
    Process parameters were optimized to manufacture soymilk and tofu in commercial production unit. The quantity and quality attributes of soymilk and tofu prepared by using different combinations of bean to water ratios (1:5; 1:6 and 1:7 w/v) and different steam pressures/temperature (0.75, 1.1 and 1.4 kg/cm2) at the time of cooking slurry in grinder cooker were accessed. Soy milk yield was maximum 6.8 litre per kg of beans in 1:7 bean to water ratio and at steam pressure of 1.4 kg/cm2 milk yield reduced when bean to water ratio decreased. Protein per cent in soymilk increased with decrease in bean to water ratio. It was maximum 4.4 per cent at 1:5 bean to water ratio and at 0.75 kg/cm2 cooking steam pressure. Fat percent was maximum 2.27 at 1:5 bean to water ratio and steam pressure of 1.4 kg/cm2. Tofu prepared using citric acid as coagulant yielded good textured and white coloured tofu with maximum yield of 240 gm per liter of soymilk. Protein and fat per cent in tofu depends on fat and protein present in soy milk. Shelf life of soymilk and tofu in ambient conditions was observed to be one day while these can be stored for 12-13 days under refrigerated conditions.

    Optimization of ridge and furrow dimensions for development of tractor drawn multi crop ridger seeder
    (CCSHAU, 2009) Jena, Swagatika; Sharma, D.N.
    Dry land agriculture contributes a major share to economy of India’s total agricultural production. Therefore for sustainability of dry land agricultural production needs adequate emphasis on significance & choice of proper agricultural machinery for various agricultural operations. Heavy crust formation during the rainy season and inadequacy of moisture at the time of seeding of rabi crops especially gram and raya are the most important reasons of obtaining low yields in the dry farming areas. During Kharif season, moisture is generally high at planting stage but moisture conservation becomes important during the growing season. Whereas conservation practices have to be adopted during kharif season on the fallow lands where rabi crops have to be raised. In this context ridge and furrow system of planting of crops with the help of ridger seeder ensures seed placement in wet or moist zone which results in better seed germination. The ridger seeder can be used for sowing of both kharif and rabi crops with shallow soil cover over the seed. The advantage of sowing by ridger seeder is that it makes the dry upper layer soil into ridges and sowing was done in the furrows at appropriate depth. It also works efficiently even when the moisture is at a depth of 15-20 centimeters. The ridger seeder machine can not control all the factors involved in seedling emergence but it can have an important influence on formation of appropriate size of ridge & furrow and precise control of seed depth, placement of seeds into moist zone and non crusting condition above the seeds and good germination. So for development of appropriate ridger seeder these factors should be optimized to get better crop stand. Therefore, in this study an attempt has been made to optimize the ridge furrow dimensions as well as the draft requirement of the multicrop ridger seeder. The ridger bottom of potato planter was selected from four different type of ridger bottoms tested (ridger bottom of existing ridger seeder (B1), ridger bottom of bed planter (B2),ridger bottom of sugar cane planter (B3) and ridger bottom of potato planter (B4)) for use in improved multicrop tractor drawn ridger seeder. Ridger bottom of this had minimum draft requirement i.e. 150 kg /bottom as compared to other three ridger bottoms (i.e. B1(159.00 kg/ bottom), B2(163.25 kg/ bottom) and B3 (177.30 kg/bottom) respectively). Ridger furrow dimensions of B4 were also close to optimum ridge furrow dimensions i.e. 600mm, 300mm, 200mm (top, bottom, depth) of furrow. The optimum ridge furrow dimensions were selected based on maximum seedling emergence (i.e. 42 seedlings /m row length in raya crop, 14 seedlings/ m row length in chick pea crop), optimum moisture distribution across the ridge (i.e. 17.68% wb in raya crop, 17.67% wb in chick pea crop ) & significant saving in irrigation water (i.e. 50.42 % in raya crop, 52.29% in chick pea crop) under lab. conditions. The ridge furrow dimensions optimized as 600mm bottom width, 300mm top width & 200mm height of ridge. Modifications were carried out & incorporated in ridger bottoms of potato planter i.e. Extended mild steel plates of appropriate size and shape were attached to ridger bottom wings at a height of 30cm from base of ridger bottom to avoid dropping of top dry soil on already sown line. Proper adjustment was done to set the ridger bottom according to optimum ridge furrow dimensions obtained under lab. condition. The field evaluation of improved tractor drawn multicrop ridger seeder was conducted at farmer’s fields of Neolikhurd and Balawas villages & farm area of SST Department in two crops raya (Cv. RH-30 ) & chickpea (Cv. HC-5). The results were compared with farmer’s practice. The field capacity of the machine was found to be 5 ha / day in both raya & chick pea crops. Seed germination of raya crop sown by improved tractor drawn multicrop ridger seeder recorded was about 10-14 seedlings / m row length & plant stand of 9-10 plants / m row length. Where as only 6-7 plants / m row length were obtained in farmer’s practice. In chickpea seed germination of 9-14 seedlings/ m row length& and plant stand of 7-13 plants/ m row length were observed in crop sown by improved tractor drawn multicrop ridger seeder in comparison to only 5-7 plants / m row length in sowing done by seed cum fertilizer drill . This signifies that seed germination was increased to about two fold by using improved tractor drawn multicrop ridger seeder as sowing machine for raya and chickpea crops. The extent of saving in irrigation water was found in to 45% tube well irrigation source & 39.62 % in canal irrigation water source with the use of tractor drawn multicrop ridger seeder. In addition moisture across the ridges and furrows recorded after first irrigation was also quite uniform in a set of ridge furrow ridge i.e.15.17, 18.52, 15.40% wb., respectively. The ridge & furrow system of planting of rabi crops with the help of improved tractor drawn multicrop ridger seeder has manifold advantages over farmer’s practice. This also adds to recent conservation tillage system in modern agriculture.

    Development of a steam blancher for vegetables
    (CCSHAU, 2009) Bhatt, Kailash Chander; Garg, M.K.
    The present investigation was carried out on "Development of steam blancher for vegetables". Three pressure and time combinations were selected. Trials were done on each combination with three replications. Pressure of 240 kPa and time 4minutes duration gave zero enzymatic activity. Samples were dried and further tested for yield and color quality. A steam blancher has been designed and developed for 10 kg cut cauliflower florets on the basis of trials. Fresh Cauliflower is used for hot water (95°C, 5min.) and steam blanching (240 kPa, 4 min.). Product was cooled immediately by cold water at ambient temperature after blanching. Test was done for catalase and peroxidase activity which were founded nil. Then samples were dried in tray drier at 60°C temperature. The dehydrated samples were subjected to the yield, solid loss, color sensory, dehydration and rehydration tests. Yield of steam blanched sample was higher (9.7%) than hot water blanched samples (8.24%). Color and flavor retention in steam blanching was better. Solids loss (7.6%) in hot water blanching were found to be higher than steam blanched samples (5.4%). There was not any significant difference in drying rate by both methods. Rehydration ratio of steam blanched cauliflower was more. Dehydration ratios of steam blanched sample were less than hot water blanched. Organoleptic quality of steam blanched samples was better in both rehydrated and dehydrated samples. Energy consumption for steam blanching (300.9 kJ/kg product) is less than hot water blanching.

    Development and testing of packages for transportation of guava (Psidium guajava L.)
    (CCSHAU, 2009) Alam, Md. Mahfooz; Garg, M.K.
    The study on development and testing of packages for transportation of guava fruits was undertaken to evaluate the effect of different types of packages and vibration level during transportation on the shelf life of guava fruits under ambient storage environment. Guava fruits were packed in CFB box, plastic crate, wooden box and bamboo basket each. CFB box with cushioning material was also used. Fruits packed in respective boxes were tested for the simulation vibration at two levels of, 150 rpm and 200 rpm each for two level and of time period of 3 hours and 6 hours each. The quality of guava fruits was observed in terms of physiological loss in weight, firmness, total soluble solids, ascorbic acid and acidity. In all the treatments given, physiological loss in weight increased with storage duration and intensity and duration of vibration, where as fruit firmness and ascorbic acid decreased with increasing storage period. Total soluble solids increase steadily during storage. Based upon above parameters, among four types of packages CFB box was found to be the best package maintaining the fruits more fresh and healthy during the simulated vibration treatments and at ambient storage conditions with the minimum losses. The CFB box was most suitable package in all respect. Cushioning material as paper cuttings had positive correlation with the quality parameters. Fruits packed in CFB box was found to result in reduction of losses and keeping the guava fruits more healthy as compared to other three types of packages. The CFB box of most suitable size and dimension for both short distance and long distance transportation was also calculated.
