苹果清汁饮料生产工艺研究

Research on the Production Process of Apple Clear Juice Beverage

[目的]确定生产苹果清汁饮料的配方及工艺技术。[方法]以浓缩苹果汁为原料,经过稀释、调配、护色、杀菌等重点工序处理,生产苹果清汁饮料。通过正交试验,确定产品的最佳生产配方,同时比较了半胱氨酸、亚硫酸氢钠、VC对苹果清汁饮料的护色效果。[结果]试验得出,苹果清汁饮料的最佳生产配方为:柠檬酸0.15%,柠檬酸钠0.20%,单宁酸0.06%,白砂糖6%,浓缩苹果汁16%。半胱氨酸、亚硫酸氢钠、VC3种物质对苹果清汁饮料的护色效果存在较大差异,综合考虑产品的质量安全,选择0.60%VC为最佳护色剂。[结论]该研究可为工业化利用浓缩苹果汁生产清汁饮料提供一定的理论依据。

[Objective] The study aimed to determine the formula and production process of apple clear juice beverage.[Method] Concentrated apple juice was used as the raw material in this experiment,apple clear juice beverage was produced through dilution,blending,color protection,sterilization and other key processes.By using orthogonal test,the best formula of the apple clear juice beverage was determined,and then the color protection effects of three color protection agents Cys,NaHSO3 and VC on the apple clear juice beverage were compared.[Result] The best formula of the apple clear juice beverage was composed of 0.20% citric acid,0.20% sodium citrate,0.06% tannic acid,6% white sugar and 16% concentrated apple juice.Besides,there was a big difference among the three kinds of color protection agents in the color protection effects on the apple clear juice beverage.Considering the quality safety of the product,0.60% VC was chosen as the best color protection agent.[Conclusion] The research could provide theoretical references for using concentrated apple juice to produce apple clear juice beverage.
