A new discovery could mean that avocados can stay fresh for longer than ever before! A team of researchers have developed a chitosan-based coating for avocados that can reduce oxidation and extend the shelf life of the fruit. The chitosan coating is a natural, biodegradable material derived from crab and shrimp shells. The coating is composed of a thin layer of chitosan and a combination of lactic acid, citric acid, and vitamin C. This combination of ingredients provides an effective barrier against oxygen and moisture, which helps to preserve the freshness of the avocados. The researchers have tested the effectiveness of the coating and have found that it can increase the shelf life of the fruit by up to 2-3 weeks! This is great news for avocado lovers who want their avocados to stay fresh for longer.
