Abstract

The purpose of this research was to determine the effect of centrifugation on the physical, chemical, and sensory characteristics of pineapple juice. The study employed a Factorial Completely Randomized Design (CRD) with two treatment factors: factor A (rotation speed) and factor B (rotation time), each consisting of three levels of treatment. Each treatment was repeated three times. Factor A included A1 = 1,500 rpm, A2 = 2,000 rpm, and A3 = 2,500 rpm, while Factor B included B1 = 5 minutes, B2 = 10 minutes, and B3 = 15 minutes.The observed parameters in this study included physical characteristics (color L*, a*, b*), chemical characteristics (total acid, vitamin C, total dissolved solids, pH), and sensory characteristics through a hedonic test (aroma, color, and taste). The results showed that centrifugation speed and duration significantly affected lightness, redness, yellowness, total acid, vitamin C, pH, and sensory evaluation scores, but had no significant effect on total dissolved solids. The interaction between the two treatment factors had no significant effect on pH. The 1,500 rpm speed treatment with 5 minutes time is the best treatment based on the total acid value of 14.60%, total soluble solids of 12.83 ̊Brix, as well as the average hedonic score for taste of 3.84 and aroma of 3.60 which is favored. Keywords: pineapple, centrifugation, and fruit Juice.
