摘要: 以姜汁、酶解鲜牛乳为原料,探讨了姜汁乳饮料的制备工艺条件。以姜汁乳饮料的感官评定为标准,通过单因素实验和正交实验,确定姜汁乳饮料的最佳工艺参数为:胰蛋白酶添加量0.05%,p H7.5,姜汁添加量15.0%,白砂糖添加量5.0%;同时,选用羧甲基纤维素钠∶黄原胶∶海藻酸钠=1∶2∶1的复合稳定剂,添加总量为0.3%时,饮料的稳定效果最好。生产出的姜汁乳饮料具有姜汁和酶解牛乳的独特香味、组织细腻,风味俱佳,能满足产品的品质要求。Abstract: Using hydrolyzed milk and ginger juice as raw material, the manufacture processing of ginger juice and hydrolyed milk beverage was studied.The optimal conditions were determined by the adoption of single- factor test and orthogonal experiment, the best solution were as follows: casein 0.05%, p H7.5, ginger juice 15%, sucrose 5.0%, and the composite stabilizer ( carboxymethyl cellulose sodium∶xanthan gum∶ sodium alginate = 1∶2∶1) was 0.3%. The beverage obtained with this technology had special ginger juice and hydrolyed milk flavor, well organized properties and good taste that could meet the quality requirements of products.
