为了研发一款风味独特、营养丰富的拐枣汁,以感官评价为指标,通过单因素实验优化了拐枣汁加工工艺,分别研究了出汁率、脱涩和澄清等关键工艺,在此基础上,以拐枣汁为原材料,白砂糖、柠檬酸及食用盐为辅料做调配实验,通过正交试验进行配方优化.确定最佳配比是添加白砂糖 3%,柠檬酸 0.10%,食用盐 0.03%;确定提高出汁率果胶酶的最佳添加量为 0.09%,脱涩单宁酶的最佳添加量为 0.15%,澄清拐枣汁所需的明胶最佳添加量为1.2%.此时产品澄清透明,酸甜适宜,拐枣风味浓郁,稳定性最好.
Optimization of Processing Technology for Honey Tree Juice and its Quality Detection
Using sensory evaluation as indicator,single factor experiment was applied to optimize the three key processing technology for honey tree juice.The amount of pectinase,tannase and gelatine added was 0.09%,0.15%and 1.2%.Then the formula was determined by orthogonal experimental method.The optimum content of sugar,citric acid and salt was 3%,0.10%and 0.03%,respectively.The obtained honey tree juice was light yellow,clear and transparent,with suitable sour and sweet taste and unique flavor.
