Avocado peel is a by-product obtained in high amounts in the food industry with no further applications despite
its richness in bioactive compounds. In this context, an efficient “green” microwave assisted extraction (MAE)
was optimized to maximize the extraction of bioactive polyphenols. Moreover, the phenolic composition of the
developed green avocado extract was characterized by HPLC coupled to MS analysers and the potential applications
for the food industry were studied assaying different bioactivities. Thus, the matrix metalloproteinases
inhibition, the antioxidant capacity and the antimicrobial activity against gram-positive and gram-negative
bacteria, yeast and mold were tested. The results pointed out both, high matrix metalloproteinases inhibitory
capacity and antioxidant activity of avocado peel MAE extract. These findings suggest the potential food industry
applications of this extract as natural food preservative, functional food ingredient or nutraceuticals with antioxidant
and anti-aging activities.
