Study on Optimized Process on Producing Navel Orange Juice with Pectinase
[ Objective] The research aimed to study the optimized process on producing Navel orange juice with pectinsse. [ Method ] The influence factors of producing Navel orange juice by pectinase were studied. And the enzyme reaction was optimized by mono-factor and orthogonal experiments. [ Result ] The results showed that the optimum reaction condition parameters were 0.06% pectinase, at 45 °C and pH 4.0 for 0. 5 h. The highest juice yield could reach 53.93%. [ Conclusion] This research could provide scientific basis for the deep production of Navel orange juice.
