The use of natural compounds with antimicrobial activity and coating properties, have been known since ancient times. These natural compounds are less harmful than synthetic compounds. Also use of nano plastic is a new strategy in post-harvest technology. In this study, the effects of carnation ethanol extract at concentrations of 0, 50, 100 and 150 ppm and Aloe Vera gel at concentrations of 0, 50, 75 and 100 percent with or without nano plastic examined based on a factorial experiment in a completely randomized design with 3 replicates on postharvest quantitative characteristics of Gaviota strawberry cultivar. Traits consist of wet weight, pH, total soluble solids and titrable acidity was evaluated at the second and third weeks of storage. The results showed that the use of Aloe Vera gel and nano plastic significantly increased total soluble solids and titrable acidity of strawberry. Carnation extract significantly effects on weight and acidity of strawberry and best performance observed in 100 ppm treatment of carnation extract. Use of Aloe Vera gel also significantly increased the weight, total soluble solids and acidity of strawberry and best performance observed in 100% concentration of Aloe Vera gel. Use of plastic produced with nano technology showed the lowest rate of weight loss. The interaction effects of nano plastic, Aloe Vera gel and carnation ethanol extract significantly increased strawberry total soluble solids.
