摘要

The invention relates to a method for preserving fresh products of plant origin, such as fresh and pre-cooked vegetables, and whole fruits and pulps, based on coating the pieces of fruit or vegetable with a film of biopolymer having microbial activity. The biopolymer film can be produced from a solution of chitosan and organic acids. Once coated, the fruits and/or vegetables are introduced into perforated containers from recyclable PET, and stored at 3°C.
