Chitosan-based coating to optimize the quality of cape gooseberry (Physalis peruviana L.)
The cape gooseberry (Physalis peruviana L.) is recognized in national and international markets as an exotic fruit with high nutritional value. However, its short shelf life and post-harvest losses affect its marketing. The objective of this research was to develop the formulation of an edible coating to extend the useful life of the fruits, based on a Box-Benhken response surface design, using different concentrations of chitosan (1, 1.5 and 2 %) (w/w), beeswax, and glycerol (1, 2 and 3 %) (w/w). Weight loss, firmness, color index, and respiration rate were the response variables. The generated quadratic polynomial models were suitable to explain the effects of chitosan, beeswax, and glycerol concentrations. Experimental validation confirmed the suitability of the cape gooseberry coating formulation using response surface methodology with 1.33 % chitosan, 2.14 % beeswax, and 1.29 % glycerol. The coating maintained the physiological and physical properties of cape gooseberry for up to 15 days at room temperature.
