Sustaining High Value Agricultural Products in Cold Storage Systems in India: Mitigation of Environmental Impact through Alternative Energy-Mix
type: item
description: With the changing consumption pattern, people’s demand for high-value agricultural products (HVAP), such as meat, fish, eggs, fruits, vegetables, milk, and milk products, has been increasing in India in recent decades. This has led to a growth in the production of HVAP and an increased requirement for cold storage, which currently has an installed capacity of 37.5 million tons. The cold storage sector, which primarily uses vapor absorption and vapor compression technologies, is a significant consumer of energy and a potential cause of environmental degradation in India. This sector consumes 6 percent of the annual electrical energy output and produces 2.35 percent of carbon dioxide emissions in the country. Based on the changing consumption patterns and production trends of HVAP, the current study makes projections for the production of HVAP, required cold storage capacity, resultant energy consumption, and carbon dioxide emissions for 2030, 2040, and 2050. The study further shows that the use of an alternative energy mix through a switch from non-renewable to renewable energy can significantly reduce the share of the cold storage sector in total emissions to a mere 0.41 percent by 2050, thereby improving India’s energy and emissions future.

Formulation And Sensory Evaluation of Waterchestnut Flour Laddoo
type: item
description: After chestnut flour was used to prepare Ladoo by incorporating processed water chestnut through sun drying, water chestnut flour Ladoo was standardized with different percentages of water chestnut flour. The percentages used were 0% (T0 as control), 5% (SDT1), 10% (SDT2), 15% (SDT3), and 20% (SDT4), respectively. Water chestnut flour incorporated Ladoo with 0% water chestnut flour was treated as the control. The nutritional contents of the sun-dried water chestnut flour were evaluated using AOAC methods. The proximate composition of SDT (sun-dried water chestnut flour treatment) for moisture content, protein, fat, total ash, crude fiber, and carbohydrate were 11.02 g, 12.42 g, 3.44 g, 2.93 g, 0.54 g, and 70.19 g, respectively. Water chestnut flour is a potential source of potassium and calcium, with levels of 1298.64 mg/100g and 89.26 mg/100g, respectively. The water chestnut flour showed good antioxidant content. In the evaluation of sensory characteristics of water chestnut Ladoo, a significant difference (P<0.05) was found among all treatments (SDT1, SDT2, SDT3, and SDT4). The differences were observed in terms of appearance/color, texture, taste, flavor, and aftertaste. The various products were also found to be a good source of nutrients, particularly in terms of protein, carbohydrate, minerals, and antioxidants. The incorporation of sun dried water chestnut flour Ladoo with 10% was found to be effective in maintaining better health conditions for everyone.

Optimization of pretreatments and sugar concentration of strawberry candy
type: item
description: The aim of the research was to develop a self-stable dehydrated strawberry product using different pretreatment and sugar solutions on the characteristics of strawberry candy. Whole strawberry candy was prepared using ripe strawberry fruits of the Sweet Charlie cultivars. The strawberries were washed in running tap water and blanched in hot water for 2 minutes. Pretreatments were given using 3 different combinations of chemicals, among which treatment C (2% Ethyl Oleate + 1% Citric acid) was selected based on the color and maximum ascorbic acid retention. The strawberries were then immersed in sugar solutions with concentrations of 40%, 50%, 60%, and 70% for 3-5 hours. The product obtained by osmotic dehydration is more stable during storage due to the low water activity imparted by solid gain and water loss. The concentration of sugar syrup 700B with a dipping time of 3 hours at 45°C was found to be suitable based on the solid gain-water loss ratio.

Studies on the drying of oyster mushrooms (Pleurotus sajor-caju) and its utilization in mushroom-incorporated cookies
type: item
description: The present investigation was carried out to study the drying of oyster mushrooms by involving two methods, namely hot-air oven drying and vacuum drying, after different pre-treatments. There was a decrease in browning of mushrooms dried after blanching and steeping in anti-browning agents such as citric acid (0.5%) and ascorbic acid (0.5%). The browning was observed to be lowest in vacuum-dried mushrooms compared to hot-air oven-dried mushrooms. Therefore, the mushrooms dried by vacuum drying techniques, pre-treated with citric acid (0.5%) and ascorbic acid (0.5%) solutions after blanching, were utilized for the preparation of mushroom powder for incorporation in cookies. The cookies were prepared by incorporating mushroom powder at 5%, 10%, and 15% by replacing wheat flour and were subjected to organoleptic evaluation by a semi-trained panel. The cookies were moderately acceptable, having an organoleptic score of more than 7.0 as per a 9-point hedonic rating scale. However, the cookies containing a higher level of mushroom powder (15%) scored slightly lower (having an overall score of less than 7) compared to other formulations. These products can provide significant support against protein-energy malnutrition (PEM), obesity, cardiovascular diseases, diabetes, and other lifestyle disorders that have a wide prevalence in different sections of society.

Development of Chicken Nuggets by Incorporation of Vegetables
type: item
description: Chicken nuggets are a popular convenience food enjoyed by people of all ages. However, concerns about the nutritional content and overall healthfulness of these products have led to an increased demand for healthier alternatives. This project focuses on the development of chicken nuggets that are not only delicious but also fortified with the goodness of leafy vegetables, offering improved nutritional value without compromising taste and texture. Chicken and fenugreek, raw materials, were procured from a public market and given the essential pre-treatments like washing, grading, and sorting. A 0.2% citric acid solution was applied to fenugreek leaves for 30 minutes. The fenugreek was dried by applying sun-drying and tray-drying methods after being treated with citric acid and other raw materials. First, boneless chicken breast was weighed, cleaned, and chopped into 8mm small pieces. Further, it was ground to make breadcrumbs. Ground spices and dehydrated vegetable powder were added to the mixture, and dough was made. Further, the dough was cut into small pieces and dipped into the breadcrumbs. The product can be kept in the freezer at a temperature of 0 to 4°C for up to two months to be used later. It should be cooled and packed in polyethylene bags. Storage should be at -18°C. Sensory and nutritional analysis were done. Finally, the product was checked for microbial safety and quality assurance. Various sensory attributes were studied for fiber-rich chicken nuggets enriched with fenugreek powder. Sensory evaluation during storage was done for over 45 days at room temperature. Sensory attributes such as appearance, flavor, taste, and overall appropriateness showed a decreasing trend during the storage period. Sensory attributes decreased during a storage period of 90 days. The developed chicken nuggets were more acceptable till the 60th day, showing an overall acceptability of 8.2±0.21. The sensory scores were least on the 90th day. The overall acceptability of the …

Standardization of Vegan Yoghurt from Coconut and Soya Bean Milk Enriched with Watermelon Juice
type: item
description: The research in recent times is mostly focused on plant-based or non-dairy milk substitutes. The issue of insufficient dairy milk supply, dairy milk allergy, or lactose intolerance is increasing the preference for vegan milk or dairy milk alternatives. Due to the health benefits and nutritional value of soybean milk, coconut milk, and sesame milk, they are the perfect substitutes for dairy milk. Soaked and blended coconut and soybeans were filtered through muslin cloth to extract the milk. The extracted milks were used in different proportions to develop and standardize samples (S) of plant-based vegan yogurt. 1% lactic acid bacteria was used for fermentation, namely, S1 - coconut milk and soy milk yogurt (50%:50%), S2 - coconut milk and soy milk yogurt (75%:25%), S3 - coconut milk and soy milk yogurt (75%:25%), S4 - coconut milk and soy milk yogurt with watermelon juice (50%:40%:10%), and S5 - coconut milk and soy milk yogurt with watermelon juice (50%:30%:20%). The duration of the fermentation process and the quality of the fermented milk were tested, and the pH was recorded at different time periods. Nutritional quality and organoleptic properties were analyzed. The results showed that the most acceptable yogurt was sample S4 - coconut and soy milk yogurt with watermelon juice (50%:40%:10%). The results also showed that the developed value-added plant-based yogurt had superior nutritional and sensory attributes compared to conventional yogurt. Plant-based yogurt is the best option for vegans as a replacement for dairy yogurt and to prevent malnutrition.

Postharvest Quality and Shelf life of Garlic Bulb as Influenced by Storage Season, Soil Type and Different Compound Fertilizers
type: item
description: The experiment was conducted twice during rainy (2011/12) and dry (2012/13) seasons at Debre Zeit Agricultural Research Centre, Ethiopia, to evaluate effects of pre-harvest fertilizer application, soil type and storage season on postharvest quality and storability of garlic bulb. The treatments comprised twelve different fertilizer types and doses i.e. control, recommended N and P (92 and 40 kg ha-1), three rates of Azofertil (100, 200 and 300 kgha-1), four rates of Basic (100, 200, 400 and 600 kgha-1) and three rates of D-coder (100, 200 and 400 kgha-1) evaluated in two soil types (Andosol and Vertisol) and replicated thrice using Complete Randomized Block Design. Two storage seasons (dry and Rainy) were used for bulbs storage. Significant variations in storability and quality of bulbs were recorded to the fertilizers, soil type and storage season. Higher rates of fertilizers improved storability and quality of bulb whereas higher weight and diameter losses were observed in bulbs from control plot and plots treated with lower levels of each fertilizer. Garlic grown on Andosol and subsequent storage during the rainy season recorded better bulb qualities with long storability. D-coder at the rates of 200 and 400 kgha-1, followed by Azofertil at 200 and 300 kgha-1, recorded higher percent of dry matter, total soluble solids and pungency of bulbs and lower percent in weight and diameter losses. Thus application of these fertilizers on Andosol is a better compromise for post harvest quality and shelf life of garlic bulbs under ambient storage conditions.

Effect of Parboiling Treatment on the Milling Quality of Selected Rice Varieties
type: item
description: Based on previous results indicating excessive milling loss inherent in rice milling process in Ethiopia, a study was conducted to evaluate the effects of parboiling treatment on three released (Gumara, Kokit, and Tigabe) and one local (X-Jigna) rice varieties. Parboiled and un-parboiled rice samples were milled using small and portable Rice Whitener (SRW). The result has indicated that the response for Parboiling is variety specific. But, in general, parboiling resulted in improved milling quality in most of the studied varieties. An overall increase in Milling yield (from 62.70 to 65.83%), milling recovery (from 79.50 to 83.97%) and whole grain yield (from 27.83 to 37.68%), was observed while milling loss has reduced (from 16.50 to 12.50%) by this treatment. Likewise, parboiling reduced machine throughput and output. Milling qualities of Gumara and Tigabe and, to some extent, Kokit varieties had been improver and that of X-Jigna declined when milled parboiled. Tigabe and Kokit had shown more or less similar milling properties when milled raw but Tigabe had shown better milling qualities when milled after parboiling. Thus, from the overall results of the research it become clear that milling qualities of the three varieties (Gumara, Tigabe,and Kokit) can be improved by parboiling. But parboiling had undesirable consequences on milling qualities of X-Jigna variety. It is therefore recommended that, along with improving the design of SRW machine, use of parboiling for selected varieties should be encouraged. Besides, under raw paddy milling conditions varieties with better milling quality as X-Jigna should preferably be promoted than lower milling quality Gumara variety. Improving the milling quality of Gumara and Tigabe by parboiling may also be useful.

type: item
description: The Kinnow mandarin (Citrus nobilis x Citrus deliciosa) fruits of uniform size, disease and bruise free were picked randomly from all the four directions of the plants with the help of secateur. The fruits were sorted and washed with chlorine solution (100 ppm). Thereafter, the fruits were coated with ‘Nipro Fresh SS 40T and SS 50’ formulations. The fruits were air dried and packed in corrugated fibre board boxes (10 Kg capacity). The coated and control (uncoated) fruits were stored under cold storage conditions (5-7°C and 80-85% RH) and under ambient conditions (11-19°C and 80-85% RH). The various physico-chemical attributes of fruits were recorded in 30, 45 and 60 days in cold stored fruits and at 5, 10 and 15 days in fruits stored at ambient conditions. The results of the study indicated that Kinnow fruits coated with ‘Nipro Fresh SS 40T or SS 50’ showed significant delay in the change of weight loss, firmness, TSS, titratable acidity and vitamin-C content of Kinnow fruits. The present study envisaged that Kinnow fruit wax coated with these formulations can be successfully stored for 45 days under cold storage conditions (5-7oC and 90-95% RH) and for 10 days under ambient conditions (11-19oC and 65-70% RH) with highly acceptable sensory quality. The uncoated fruits, on the other hand, maintained postharvest shelf life of 30 days in cold storage and 5 days at ambient conditions.

Influence of Germination Time on Some Physical Properties of Germinated Paddy (Oryza sativa L.)
type: item
description: The physical properties of grains are important factors in designing efficient food processing, handling and storage systems. In this work we investigated the influence of degree of germination (in terms of the duration of germination treatment) on some geometric, mass-related and flow-related properties of germinated paddy grains. Paddy grains germinated at 38oC and 85% relative humidity over a period of 24, 48 or 72 hours and dried to a moisture content of about 11% (wet basis) after or without parboiling, were used for physical characterization. Results show that degree of germination had a significant influence on the mass properties of paddy grains, with evidence of linear decrease in both bulk density and 1000-grain mass with increasing germination time. A similar trend was observed for the porosity of both raw and parboiled germinated paddy grains.

Postharvest Technology of Button Mushroom: A Socio-Economic Feasibility
type: item
description: Fresh mushroom is highly perishable and deteriorates immediately after harvest. It develops brown colour on the surface of the cap due to the lyses of cell and enzymatic action of polyphenol oxidase that results in shorter shelf life. Being highly perishable in nature, the fresh mushrooms need to be processed to extend the off-season availability by adopting appropriate postharvest technology and processing into value-added products. The value-added products are the need of the hour for the mushroom growers not only to reduce the losses but also to enhance the income by value-addition to boost the consumption of mushroom. The possible value-added products can be developed either by converting freshly harvested mushrooms into ketch-up, murabba, candy, chipsand pickles or by dehydrating freshly harvesting mushrooms into dehydrated form and then making soup powder, biscuit, nuggets and Ready–to–eat mushroom curry (RTE). This review article summarizes the information regarding postharvest technologies and value addition of fresh mushroom generally followed worldwide.

type: item
description: Elephant foot yam, Amorphophallus paeoniifolius is an edible aroid cultivated in the tropical countries. Corm or tuber is the storage organ and is used as seed material or as a vegetable after cooking. Owing to the indisputable palatability, cooking quality, medical utility and therapeutic values of its tubers, this has been dubbed as “King of tubers”. Infestation by the mealy bug, Rhizoecus amorphophalli is a serious problem during its long term storage. This study aims at analysing the physicochemical and textural changes in the mealy bug infested tubers of elephant foot yam. For the study, infested and uninfested tubers were stored for 4 months at ambient conditions and data on the physico-chemical and textural changes were evaluated at monthly interval. The moisture content showed a regular decreasing trend in both uninfested and infested tubers registering higher loss for infested set throughout the storage period. Starch and sugar content decreased with storage period whereas fibre and ash content increased. Functional properties of flours from the uninfested tubers were low compared to the infested tubers and these parameters slightly increased with storage period. Texture profile analysis showed that the firmness of the infested tubers were more than that of the uninfested tubers in their native form.
