Coating of Layer-by-Layer Assembly Based on Chitosan and CMC: Emerging Alternative for Quality Maintenance of Citrus Fruit

Citrus fruits are susceptible to microbial infection during storage and transportation, leading weight loss, quality deterioration even physiological decay. In this study, a layer-by-layer (LbL) self-assembly edible coating based on chitosan Sodium carboxymethyl cellulose (CMC) was prepared using electrostatic deposition. Postharvest citrus (Citrus reticulate cv. ‘Chunxiang’) were coated either with the LbL coating, which exhibited an increased transmission rate of water vapor, or single coating. The data some indexes compared after being stored at 13 ± 2 °C relative humidity (RH) 80–85% (shelf-life condition) for 10 days. Results demonstrated that deposited effective maintaining morphological microstructural attributes, increasing surface brightness, firmness content titratable acid ascorbic acid, as well reducing loss by about 0.8%. in present study indicated could have potential maintain postharvest storage.
