Abstract: | About 161 million tons of tomatoes were produced per year in the world in 2012. However, the large amount of this production was lost partly due to a lack of effective facilities during storage. Such a loss can be minimized using an alternative method which applies carboxymethyl cellulose (CMC) based edible coating. Pineapple core, which creates waste problem in many countries, is a source of cellulose and can be derived into CMC. The aim of this study was to investigate the effect of CMC based coating from 2% pineapple core (CMCpc) and commercial CMC (CMCc) compared to control on weight loss, firmness, total color difference (ΔE), total soluble solid (TSS) and Vitamin C content of grape tomatoes in ambient storage (25oC and 70%). The results showed that in the last day observation, coated grape tomatoes using CMCc and CMCpc had a lower weight loss (14.63 and 24.51%), lower TSS (5.14% and 5.12% Brix) and higher vitamin C content (28.47 and 27.67 mg/100g) than control (24.71% weight loss, 5.6% Brix, and 26.68 mg/100g). However, there was no effect observed in firmness and ΔE of tomatoes with and without coating (p<0.05). These results indicated that CMC coating can delay the moisture loss and ripening process of tomatoes in ambient condition. |
