Abstract

Highlights: The use of nanomaterials for the inhibition of PPO has not been tested before. The use of mesoporous silica materials (SBA-15, SBA-3, and MCM-48) at different pH has been tested. Pore size and volume are the characteristics with higher influence on the PPO immobilization. SBA-15 adsorbs the larger quantity of PPO at pH 4.00 and offers an inhibition close the 50% in apple extracts. Abstract: The ability of a number of mesoporous silica materials (SBA-15, SBA-3, and MCM-48) to immobilize polyphenol oxidase (PPO) at different pH has been tested. Pore size and volume are the structural characteristics with higher influence on the PPO immobilization. Mesoropous material SBA-15 adsorbs a larger quantity of PPO at pH 4.00 and offers an inhibition of enzymatic activity close the 50% in apple extracts.
