The use of ozone for the sanitization of fresh-cut produce has been postulated during all steps of the cold chain from harvest to consumption. However, little is known about its effects on the postharvest quality of minimally processed spinach. In the present study, the effects of different doses of ozone on the storage life and quality of minimally processed spinach were determined and compared with sodium hypochlorite.

This study was conducted to determine the effects of different drying methods and cold storage treatments on the postharvest quality and nutritional properties of P. ostreatus mushroom. In the study, six different treatments including natural drying, oven drying (60°C), microwave drying (450 W), storage at -18°C, 4°C and 10°C were evaluated. After drying and cold storage, pH value, ash, protein, color, total phenolic content, total flavonoid content, antioxidant activity and element contents in mushroom samples were detected.

In India, presently about 35 to 40 per cent of the onion is estimated to be lost as postharvest losses during various operations including handling and storage. Serious losses occur during storage due to sprouting and rotting. Keeping this in view, an investigation was carried out to study the effect of different packing and storage methods on storage life of aggregatum onion cv. CO on 5.

The role of AM (Arbuscular mycorrhizal) fungi in the rhizosphere of onion at induced salt stress was studied. A pot culture experiment was set up with three levels of salts and six treatments involving mycorrhizal inoculations with host crop as onion. The initial observations of the soil physico-chemical analysis on comparison with postharvest soil revealed that there was significant difference in nutrient availability as well as uptake by the plants.

Under this study, botanicals, plant volatiles, organic acids, organic salts and essential oils were used against E. carotovora subsp. carotovora under in vitro. Based on antibacterial efficacy, curative application was formulated against decay in carrot by dipping under laboratory conditions. Out of these all treatments, EC formulated consortia (cinnamon + lemongrass + thyme) oils at 0.1% given the better results against disease reduction (98.0%), weight loss (3.0%), and preserve the edible nature.

The maximum retention of fruit quality attributes were recorded in SA (600 ppm) TSS, acidity, Vitamin C and total sugar which was followed propyl galalte (450 ppm) treated fruits. Both TSS, ascorbic acid and total sugar showed similar trends of increase up to 6th days of storage followed by a decrease. However, acidity decreased continuously with enhancement of storage period. At the end of the storage, maximum TSS, total acidity, ascorbic acid and total sugars were noted under salicylic acid (600 ppm) treated fruits, followed by fruits treated with propyl gallate (450 ppm).

Guava (Psidium guajava L.) is the fifth most important fruit crop of India, has a limited postharvest shelf life. This study explored the use of some postharvest treatments to extend the shelf life, post-harvest disease incidence and to assess the physico-chemical changes of fruits during storage and to study the effect of seasonal variation on quality and storage life of guava fruits (cv.L-49).

In onion, among the postharvest diseases, black mold rot caused by Aspergillus niger is the predominant one. The pathogen is transmitted by contaminated seed or soil. The infection usually begins at germination of onion seeds and may continue throughout storage. The purpose of the study was to explore the control of black mold of onion with various systemic, non systemic and combination of fungicides by treating the seeds. Considering per cent reduction of radial growth of Aspergillus niger, non systemic fungicide dinocap (90.28) and thiram (80.

Studies have revealed that edible coatings particularly Carnuba wax and chitosan can be used as postharvest treatment for enhancing the storability of bitter gourd gourd fruits under ambient storage conditions (temperature 27.4-32.3°C and 70-81% RH).There were seven treatments, replicated thrice and experiment was laid out in completely randomized design. The bitter gourd fruits coated with 1.0% Carnuba wax maintained higher sensory score of 6.67 in storage.

Ethylene inhibitor compound 1-methylcyclopropene (1-MCP), sanitizer chlorine dioxide (ClO2) and polyhexamethylene guanidine (PHMG) were studied to know the postharvest behavior and storage life of banana fruits (cultivar Yelakki), harvested at second stage of its ripening. Banana fruits were pretreated with the above chemicals either singly or in combination and stored in corrugated fiber board boxes at ambient condition. The 1-MCP treatment had delayed the colour change of peel as well as fruit softening and extended t h e shelf life by suppressing the respiration.

In order to extend the shelf life of banana cultivar Grand Naine was fumigated with 1-methylcyclopropane (1-MCP) at four different concentrations (100, 200, 300 and 400 ppb) @ 24h exposed time and stored at ambient conditions. Among all the treatments, 400 ppb was found to be an effective in extending shelf-life, highest retention of cell wall degrading enzyme such as Pectin methylestarase and free radical scavenging enzymes peroxidise and catalase. The entire 1-MCP treated banana showed better results over control (kept at open air @ 24h).

Guava fruits of cv. Lalit were treated with salicylic acid (SA) and 5-sulfosalicylic acid (SSA) at 1 mM and 2 mM concentration and stored at 10oC for 12 days. After storage, fruits were transferred to ambient conditions (20±2oC) for 3 days shelf life stimulation period and then observations were recorded up to 12+3 days. Results revealed that fruits treated with SA or SSA at 2 mM concentration showed minimum weight loss and colour change but maintained maximum firmness, total phenolics and ascorbic acid content.
