Abstract

The purpose of this study was to determine the effect of a variety of vegetable oil emulsions in water, as a coating material, on the quality and shelf life of tomato fruit (Lycopersicon esculentum Mill.) at room temperature (27-300C). Oil emulsion treatments in this study were palm oil (E1), sunflower seed oil (E2), sesame oil (E3), and canola oil (E4) emulsions with the same concentration of 0.5%. Additional materials that were used in making emulsion were 1% tween, 0.5% oleic acid and 3% alcohol. For comparison, the separate tomato fruits were coated with Brogdex Wax commercial (E5) with the same concentration as the oil emulsions, and without any coating material as controls (E0). This study used a Completely Randomized Design (CRD) with three replications. The results showed that the types of oil emulsions as well as brogdex wax and controls significantly affected the shelf life and quality of tomato fruit during storage at room temperature. Coating with sesame oil emulsion (E3) resulted in the highest reduction on the weight change, and intensity of decay, and the change of texture, when compared with controls and Wax Brogdex emulsions during storage at room temperature. While coating with sun flower seed oil emulsion (E2) was the second best in reducing the changes of weight and texture; however, the average of decay intensity was still higher than other oil emulsion treatments.
