Abstract

Industrial waste such as pineapple peels that accumulate in massive quantities contributes to environmental pollution. However, there is limited data on the physicochemical properties of pineapple peel for several ripening stages. The aim of this study was to determine the physicochemical properties and bromelain activity of three indexes of pineapple peel extract specifically for the variety Josapine. The method used for the analysis of physicochemical properties includes total soluble solid (TSS), pH, titratable acidity (TA), pulp content, sugar content and the casein digestion unit (CDU) method for bromelain activity. Significant differences at p<0.05 were found between TSS, pulp, pH, titratable acidity and TSS/TA ratio among an index of maturity. It was found that pineapple peel extract at maturity index 7 contained significantly the highest in titratable acidity, TSS and total sugar. From this present study, it was observed that bromelain activity in pineapple peel extract was significantly higher in maturity index 5 as compared to maturity indices 2 and 7.
