Abstract

Eggplant is one of fruit much like by many people. Postharvest handling of eggplant could reduce losses due to short shelf life. One of the method to extend the shelf life of eggplant was stored at low temperature and soaked into solution of calcium cloride. The purpose of this research was to study kinetics eggplant quality during storage. Treatment to research was eggplant soaked in solution of calsium clorida (CaCl2) with concentration 0%, 1% and 2% then stored at 28°C and low temperature (9°C). Rate of quality is analyzed using kinetic equation. The kinetics of weight losses use zero-order, first-order was for hardness change and total dissolved solids. The research result showed that soaked into solution of calcium chloride (CaCl2) was capable of inhibiting the rate of change the quality of eggplant.

Abstract

Purple eggplant (Solanum melongena L.) is a type of plant known as a vegetable that is used as a food ingredient. After purple eggplants are harvested, they still carry out metabolic processes such as respiration and transpiration. Inhibition of respiration in agricultural products can be done by cold air storage combined with dipped in CaCl2 as a pretreatment. The purpose of this study is to determine how the physical characteristics of purple eggplant are affected by temperature and CaCl2 solution concentration. The method used was a Completely Randomized Design (CRD) with two factors. The first factor is storage temperature, which consists of 9 °C and room temperature. The second factor is the CaCl2 concentration, consisting of 0%, 1%, and 2%. The parameters observed during storage were weight loss, texture, and total dissolved solids. This research was carried out for 4 days of storage and measured every day with 3 replication. The results show that dipping purple eggplant in CaCl2 and cold storage can inhibit the respiration and transpiration processes. The best treatment is to dip it in 2% CaCl2 and store it in the refrigerator.
