Evaluation of Aloe vera Gel as an Alternative Edible Coating for Peach Fruits During Cold Storage Period

Application of bio-based edible coatings, which are in line with sustainable agriculture practices, has been a hot topic in recent years. In order to evaluate the effect of Aloe vera L. gel coating, on the store ability of peach fruits, a 30-day postharvest experiment with 10-day sampling intervals was performed. A. vera gel coating had significant positive effects on the weight loss, color change, and sensory evaluation. The amount of weight loss, color change, Total Soluble Solids (TSS) and Titratable Acidity (TA) in coating was lower than control. Furthermore, our results showed that A. vera gel coating can enhance visual properties, and could also lead in more favourable taste and texture. Regarding the obtained results, it can be suggested that A. vera gel coating can enhance the qualitative and quantitative post-harvest traits of fruits, hence, it could be a suitable alternative for chemicals preservative in commercial storage of peach fruits.
