Edible Coating Effects on Storage Life and Quality of Apple
Fruits and vegetables continue to respire after harvest. A way for minimizing these problems is to coat the individual fruits and vegetables and to provide a protective film for prolonged freshness. The effect of application of Golden Delicious edible coating on weight loss, firmness and sensory characteristics was investigated for apple fruits. Apple coated with emulsion consists of sodium casein ate and glycerol then it was stored at 4*C for up to 112 days. Coating significantly reduced weight loss of the apples.The firmness of the control fruits significantly (P<=0.05) decreased with the storage time. The application of coating delayed softening of apple fruit during 112 days of storage at 4*C. Sensory characteristics of apples such as color, taste, tenderness, appearance and overall acceptability of coated apples were much better preserved while storing at 4*C for 112 days. This report results indicated that usage of edible coatings with recognized emulsion from casein at, will be effective for apple fruits preserving and positive action of surface coatings in delaying ripening of fruits postharvest physiology and quality of coated commodities fruits are proved.
