Optimum postharvest handling-effect of temperature on quality and shelf life of tropical fruits and vegetables.

Abstract

The challenge of high tropical temperature and chilling sensitive horticulture required an optimum postharvest handling to minimize the worldwide concern on the postharvest losses of tropical fruits and vegetables. To ensure the harvested produces achieves the consumer acceptability, the effect of temperature on the perishable produces along the integrated series of postharvest chain operations including harvesting, processing, storage and transportation must be crucially maintained. Even though the cooling process during the postharvest handling helps to reduce deterioration from high tropical temperature, the refrigeration storage temperature may also result in detrimental chilling injury. Quality of the produces reduced because of the development of symptoms include internal and external discoloration, abnormal fruit ripening, accelerated senescence, skin pitting, wilting, increase susceptibility to decay and loss of flavour. Optimum storage temperature for specific fruits and vegetables, temperature conditioning, intermittent warming technique, controlled atmosphere storage, chemical treatments and application of growth regulator can be applied either to retard the damaging symptoms or to increase the tolerance of the commodities towards chilling injury in order to extend fresh produces shelf life.

Development of nutrition rich mixed fruit leather from Apple and Papaya: A review

“…This could be explained by the fruits' decreased rate of respiration and transpiration as a result of the low temperature storage's higher relative humidity and lower temperature. The usage of low temperature is said to be the most essential way to improve the storage life of postharvest food since a higher rate of respiration reduces shelf life [114].…”

The pattern of production and marketing of horticultural commodities at the country border in Bengkayang regency; before and during the COVID-19 pandemic

“…The implication of the weakness of these horticultural products, it is necessary to maintain and increase the selling value of these horticultural products, post-harvest handling is needed, both preservation, making processed products, and packaging. There are many technological innovations resulting from research that has been carried out in the aspect of horticultural commodities preservation [28,[43][44][45][46] and horticultural commodities packaging [47][48][49]. However, post-harvest handling has a cost risk in preserving, packaging, and processing, so to be efficient and cost-effective in the post-harvest handling process, it is necessary to collaborate with other horticultural farmers, namely in horticultural farmer groups.…”

Automation of Refrigeration Systems for Extending Shelf life of Fruits and Vegetables in Remote Areas for Economically Weaker Section

“…proposed a solar absorption system. Apart from different types of refrigeration systems, many researchers have proposed use of different chemicals in the refrigeration system and during packaging to increase the shelf life of fruits and vegetables [21][22][23][24][25][26][27][28][29][30][31][32][33]. A chemical treatment is given which retards ripening and retains the freshness post harvest.…”
