High methoxyl pectin extracts from hylocereus polyrhizus's peels: Extraction kinetics and thermodynamic studies

The effect of physicochemical treatment on pectin yield, degree of esterification, along with the kinetics and thermodynamics characteristics was investigated in the present study. Several extraction parameters were observed to have impacted the yield and degree of esterification significantly, and...
