Abstract
Postharvest storage study of tomatoes was carried out using low density polyethylene bag (LDPE) and chlorine cleaning (NaOCl) to compare the effects of NaOCl and LDPE. The postharvest quality of tomatoes was evaluated by monitoring and analyzing the parameters including weight loss, color change, titrable acidity (TA), total soluble solid (TSS), and firmness measurement in every two-day. It was found that tomatoes washed with clean water followed by packed in LDPE bag and stored at 15oC exhibited the best result by prolonging the self-life of 10 days. On the other hand, tomatoes washed in NaOCl followed by packed in LDPE and stored at 15oC was able to prolong the shelf life of 8 days. However, tomatoes were stored at ambient temperature under similar experimental condition; the shelf life was prolonged only 6 days. Furthermore, LDPE packaging storage was found good in retaining the firmness and lightness, however, NaOCl washing was led to soften and shrive the tomatoes rapidly.
