Estimation of temperature profiles in microwaved particulates using enzyme and vision system

open access: yesLWT - Food Science and Technology, 2003
Abstract A new method, which used enzyme (peroxidase) as a time–temperature indicator (TTI) and color vision system to detect enzyme concentration was developed in this study. Peroxidase was immobilized in particulates containing potato starch and alginate. The particulates were heated in a microwave generation and transmission system from 15 to 85 s
