Technology of virgin coconut oil extraction by complex enzyme were studied.Cellulase,xylanase and pectinase were used to extract coconut oil by catalyzing coconut cream,the optimal combination of the enzymes were determined by single factor tests and orthogonal experiments.The proper technology was as follows:the amount of cellulase was 0.10%,xylanase was 0.05% and pectinase was 0.05% (based as pure coconut cream),the water addition was 40% of pure coconut cream,the pH of coconut cream was not adjusted,coconut cream was catalyzed by the complex enzyme for 24h at 50℃,then centrifugal separated the hydrolysate under 3000rpm for 10min.The yields of coconut oil was 86.65%.The harvested coconut oil was dried at 55~60℃ and under vacuum degree of 0.07~0.08Mpa for 0.5~1h,its water content and acid value could be decrease to less than 0.10% and 0.30mgKOH/g,respectively.
