Effects of Chitosan on Clarification Effects of Zizyphus jujube Mill Juice
摘要
Abstract
Objective] To discuss the optimal technology of clarified Zizyphus jujube Mill juice after chitosan treatment.[ Method] With Z.jujube juice as the materials, single factor test was carried out.The clarification technology of Z.jujube juice by chitosan was optimized by orthogonal test.With the clarity of Z.jujube juice as the index, we mainly discussed the effects of chitosan concentration, clarification time and clarification temperature on the clarification effects of Z.jujube juice were discussed.[ Result] The optimal technology was as follows:0.7 g/L chitosan dosage, 35 ℃ clarification temperature, and 1.5 h clarification time.Under this condition, the transmittance of Z.jujube juice after clarification reached 89%.Compared with the original juice, there were slight changes in pH, total glucose content, total acid and soluble solid.The pectin content was removed by more than 80%.[ Conclusion] Chitosan has relatively good clarification effects.This method is economical and practical, and can be used for the production of Z.jujube juice.关键词
