Abstract


Tomatoes are a type of fruit that people really like, they have a lot of nutritional content for body health.This study aims to determine the effect of edible coating and shelf life as well as the interaction between the two factors on the quality of tomatoes. This research was conducted at the Laboratory of Seed Technology, Faculty of Agriculture, Syiah Kuala Darussalam University, Banda Aceh, from May to June 2023. This study used a 3x3 factorial randomized block design (RBD) with 3 replications so that there were 27 experimental units. The factors studied were the concentration of edible coating  and storage time . The edible coating concentration factor consists of 3 levels, namely control, 20% and 40%. The storage time factor consisted of  3 levels, namely 1, 2 and 3 weeks. The variables observed included weight loss, moisture content, vitamin C content test, color test and organoleptic test. The results showed that the edible coating cassava starch had a very significant effect on the organoleptic color, texture and aroma. Significant effect on the organoleptic taste. The best quality of tomatoes was found in the control treatment. Shelf life had a very significant effect on weight loss, moisture content, vitamin C content, and had a significant effect on the color on the L value (brightness). The best quality of tomatoes was found at a shelf life of 1 week. There is an interaction between cassava starch edible coating and shelf life which has a very significant effect on water content and has a significant effect on the color test on the L value (brightness). The best combination of treatments for tomato fruit quality was found in the control treatment with a shelf life of 1 week.
