Tomatoes are perishable fruit that makes them deteriorate rapidly during the post-harvest chain. Therefore, the effect of calcium chloride (CaCl2), chitosan, hydrogen peroxide (H2O2), and ozonated water on the storage abil\ity and quality of tomato fruit (Solanumlycopersicum L. cv. 448) stored at 10 °C for 28 d was studied. Weight loss, firmness, fruit color, total soluble solids (TSS), titratable acidity, total carotenoids, and ascorbic acid content (AsA) of treated tomato fruit were recorded. Our results revealed that all tested treatments significantly extended the shelf-life and maintained quality of tomato fruit compared to the control. Chitosan and CaCl2 were the most effective treatments in maintaining quality attributes. Furthermore, a correlation study suggested that AsA and total carotenoids played a vital role in conserving tomato fruit quality during storage. PC1 had strong positive loading for pH, appearance, firmness, AsA, TSS, carotene, fruit color (L* & b*) and a strong negative loading for lycopene content, color (a), weight loss, and color index. PC2 had high positive loading for total acidity and total sugar content.

Loquat (Eriobotrya japonica L.) is an important sub-tropical fruit with very limited postharvest life. Therefore, in the current study, we investigated the effect of calcium chloride (CaCl2) treatments on the shelf life and quality of loquat fruit. After harvest loquat fruit treated with different concentrations of CaCl2 viz. 2%, 4% and 6% for 2 min were kept at room temperature (30±2oC) for 5 and 10 days. Untreated fruit were kept as control. The results showed that fruit treated with 6% CaCl2 exhibited minimum fruit weight loss (9.1%), external browning (8.83%), and internal browning (9.1%) after 10 days shelf period in contrast with control fruit. Lowest total soluble solids contents (9.11%), highest titratable acidity (0.53%) and juice (28%) contents were found in fruit treated with 6% CalCl2 as compared to other treatments. In conclusion, among the tested treatments, application of highest level of CaCl2 (6%) effectively maintained the quality of loquat fruit a room temperature.

Early maturing peach (Prunus persica) cultivars can fetch good market value but face a lot of post-harvest problems that lead to the post-harvest losses. The 1-methylcyclopropene (1-MCP) can provide new insights into plant ethylene responses and extend the shelf life and quality of fruits. Therefore, fruits of peach cultivar ‘Early Grand’ were dipped in various concentrations of 1-MCP (0, 0.3, 0.6 and 0.9 µg l–1), stored for 40 days at 8 ±2°C with 50% relative humidity and analyzed the fruits for physicochemical attributes at 10 days interval. The highest concentration of 1-MCP at 0.9 µg l–1 significantly improved the activity of antioxidants, catalase, free radical scavenging assay and total phenols. However, the peach fruits treated with 1-MCP at 0.6 µgL–1 was effective in retaining the ascorbic acid, lowering the weight loss and fruit decay. Therefore, peach fruits can be treated with 1-MCP (0.6 µg l–1) solution for prolonging its shelf life up to 40 days under low temperature.

Background: Capsicums having high respiration, transpiration, and ethylene production rates along with high susceptibility to microbial growth deteriorate rapidly during storage leading to higher loss. The current study was conducted to assess the effects of Perforation mediated- modified atmospheric packaging (MAP) on shelf life and quality of calcium chloride treated bell pepper (Capsicum annum). Methods: For this purposed green mature fruits capsicum annum variety Indra were pretreated with calcium chloride, weighed 1kg and packed in Low-density polyethylene with no perforation (T1), LDPE with 4 perforations(T2), LDPE with 8 perforations(T3), LDPE with 12 perforations(T4), LDPE with 16 perforation(T5) and open tray (T6) and stored at ambient room temperature of laboratory. Three replications were maintained for each treatment with CRD Design and different parameters were evaluated during the study period. Result: Capsicum stored in perforated LDPE packet exhibited less weight loss, higher shelf life and higher vitamin C content compared to capsicum kept in an open tray. With less perforations weight loss was less. Moreover, LDPE with 16 perforations can be considered the best treatment because with higher numbers of pores it exhibited comparatively higher shelf life, optimum quality of fruits and also check the spoilage of the fruits as compared to all treatments.
