Application of chitosan‐based chickpea (Cicer arietinum L.) hull polysaccharides edible coating on cherry tomatoes preservation

Bio‐active food coating having natural antioxidants has attained great attention these days. Polysaccharides extracted from bacteria, fungi, and plants are considered rich in antioxidant biomolecules. Chickpea hull which is a food waste material contains a substantial quantity of antioxidants and bioactive compounds. In this study, chitosan (CS)‐based chickpea hull polysaccharides (CHPS) edible coating of cherry tomatoes was successfully fabricated. Cherry tomatoes were characterized in terms of physico‐chemical characteristics and shelf life. In comparison to the control, it was discovered that the CS‐incorporated CHPS coatings were successful at lowering the respiratory activity, total soluble solids, total polyphenols, firmness, weight loss, lycopene content, and vitamin C as well as improving the fruit's overall acceptability. The dose dependence of each of these effects was noticed. Conclusively, using CS‐incorporated CHPS coatings could preserve the shelf life of cherry tomatoes. A useful and different approach to enhance the postharvest quality of cherry tomatoes is to utilize CS‐CHPS composite coatings. Chitosan‐based chickpea hull polysaccharides edible coating of cherry tomatoes. Physico‐chemical parameters were improved. Shelf life of cherry tomatoes was preserved.
