Abstract

The purpose of this study was to determine the effect of ethanol vapor treatment on the quality and shelf life of Siamese citrus fruits at room temperature. This study used a Completely Randomized Design (CRD) with 3 different volumes of ethanol; 0 ml, 3ml, and 6 each were trapped in 5 grams of carrageenan which had been 10 ml of distilled water and put into a tea sachet. Sachets are then placed on styrofoam bases where there are 5 Siamese oranges, then covered with LDPE stretch film plastic. Siamese citrus fruit without treatment or control is provided as a comparison. The fruit is then stored at room temperature (28 ± 20). Weight loss, damage intensity, vitamin C, total acid, total dissolved solids, color, hardness, and organoleptic tests were observed during storage. The results showed that the general ethanol steam treatment had a significant effect in reducing the level of damage, weight loss slowed the rate of change in hardness, skincolor, total dissolved solids and vitamin C compared to controls. Similarly ethanol vapor is able to provide a higher panelist preference for color, taste, aroma and overall appearance compared to controls. From the various treatment volumes of ethanol 6 ml ethanol packaging creates the best vapor to slow down the rate of damage, change the quality, reduce shrinkage and increase the preference of panelists.
