Abstract

Oranges with low grade categories have a low price, so one of the utilization efforts is combine with milk into orange milk products.. Orange milk, extracted from orange of siam cultivar and added with milk, was pasteurized using a pulsed electric field (PEF) method. The aim of this research was to analyze the changes on nutritional, physical and chemical properties and total microbes from orange milk after pasteurization. The research was conducted from July until September 2021 located in Jember. The PEF treatment was carried out using treatment time variation for 5 minutes (1 cycle), 10 minutes (2 cycles) and 15 minutes (3 cycles). Several parameters of Vitamin C, pH, dissolved solid and total microbes were observed. The result showed that PEF treatment did not significantly change nutritional (vitamin C), physical (dissolved solid), and chemical properties (pH), but total microbes very significantly change after pasteurization with PEF in compared with no treatment pasteurization. The best treatment was found in the variation of 15 minutes (3 cycles) with degradation microbial killing effectiveness reached 94.58%.
