Use of several edible natural coatings on kinnow (Citrus reticulata Blanco) fruit

Abstract

Fruit coating is an effective method in the post-harvest industry to replace the natural wax that is removed during cleaning and processing. Recently, there has been a growing interest in using natural edible coatings instead of non-prescription synthetic waxes for human health and the environment. Today consumers prefer natural products to synthetic ones. Therefore, natural fruit coatings are developed from natural ingredients (Sherak, rosin, gum Arabic, sugar industry water, ethanol) without the use of ammonia or morpholine as an alternative to synthetic coatings. Many studies have shown that fruit coatings significantly slow down changes in weight, hardness, ascorbic acid, and overall physiological loss of sensory quality during storage compared to uncoated fruits. On the other hand, this has led to a positive method, showing small variations in total soluble solids and fruit. Acidity was recorded for all treatments. Furthermore, the difference between natural and synthetic fruit coatings was not important. Therefore, natural fruit coatings are assumed to be a great alternative to synthetic fruit coatings.
