Microencapsulation of avocado pear seed (Persea Americana mill) bioactive-rich extracts and evaluation of its antioxidants, in vitro starch digestibility and storage stability

Abstract

This study evaluated the antioxidant activities of avocado seed extract as affected by solvent for extraction and formulation of microcapsule from the extract. Avocado seed powder was extracted using ethanol, aqueous ethanol, and water as solvents. The extract with the highest bioactive activity was encapsulated using corn and cassava starches as cell wall materials. The antioxidant activity, storage stability, in vitro starch digestibility and Fourier-transform infrared spectroscopy (FTIR) of the microcapsules were evaluated.
