Improvement of visual quality rate in papaya postharvest

Papaya is most commonly grown fruits crop in tropical regions of world. About 25% - 40% of postproduction losses of papaya can be observed specially in developing countries. Considerable amount of post-harvest losses of papaya is occurred due to un-hygienic conditions during post-production operations. Fruits hygiene condition is very important in order to extend its post-harvest self-life. Further, cleaning and washing practices are also very important in order to improve hygienic condition of product and directly affected to its quality. This study was conducted for scientific evaluation product call BiOWiSH? (BW) that introduced as a fruits washer and sanitizer. BW washing treatment was tested and compare with existing non-washing practices for extending the shelf life papaya. Shelf-life improvement was evaluated by altering pattern of weight loss, visual quality, firmness, total soluble solids, pH and colour. Results revealed that BW treatment was only affected marginally for improving visual quality of papaya, it was not affected significantly for altering other parameters i.e. weight loss, firmness, total soluble solids, pH and colour in comparison to non-washed papaya. Marginal visual quality improvement indicate that BW treatment was able to control microbial contamination of papaya some extend. Overall, it can be concluded that BW washing treatment was not significantly affected to improve shelf-life of papaya. ?
