Abstract

Abstract: he present research focused on the evaluation of three types of commonly used commercial packaging: Polypropylene (cellophane), polyethylene and nylon, to carry out a study on the shelf life of three varieties of fresh vegetables (asparagus, pepper and chard), during different evaluation periods, which were subjected to physicochemical analysis and were provided with optimal conditions of constant refrigeration at 7°C. It was concluded that the optimal consumption period for asparagus in polypropylene and polyethylene packaging is 7 days, while in nylon it is 8 days; In the case of chard packaged in polypropylene and nylon, it was 6 days, polyethylene 5 days and for peppers in polypropylene it is 5 days, while polyethylene 6 days and nylon in 8 days. The results of the acidity, pH, texture and brix analyses carried out on the three types of commercial vegetables do not show significant differences due to the different containers used and have similar functions in the preservation of vegetables during the time evaluated.
