Abstract

This study aims to determine the effect of temperature and time in the evaporation process on the physicochemical characteristics of pineapple juice concentrate. The study employed a Factorial Completely Randomized Design (CRD) with two treatment factors: factor A (evaporation temperature) and factor B (evaporation time), each treatment was repeated three times. Factor A (A1 = 70oC, A2 = 75oC, A3 = 80oC), while Factor B (B1 = 30 minute, B2 = 60 minute). The observed parameters in this study included physical characteristics (color L*, a*, b*, viscosity) and chemical characteristics (pH, total acid, vitamin C, total soluble solids). The results showed that the treatment of temperature and evaporation time had a significant effect on the value of lightness (L*), yellowness (b*), viscosity, pH, total acid, vitamin C, and total soluble solids. The interaction between treatment factors had no significant effect on pH and redness (a*) parameters. The treatment of 80°C and 60 minutes was the best treatment based on the high value of total soluble solids in oBrix units as a fruit concentrate product, which is also supported by vitamin C and total acid data.
