康寿老年乳饮料的研制

Study on development of consol old milk drink

确定了乳糖酶水解原料乳中乳糖的最佳工艺条件:乳糖酶用量(E/S)32.06 U/g,水解温度40℃,pH值为6.82,水解时间3.0 h;并进一步研究了利用此法生产的低乳糖原料如为主要原料生产的老年乳饮料配方:水解乳糖脱脂乳粉50 g,乙基麦芽酚0.3 g,香兰素0.015 g,葵花籽油8.25 g,酪蛋白磷酸肽9.48 g,黄原胶0.15 g,CMC-Na 0.15 g,水450 mL。结果表明,通过此种方法研制的乳饮料,充分利用了牛奶中的乳糖,避免了乳糖不耐症现象,富含多种营养成分,具有一定的保健功能。

This study identified the optimum conditions of the lactase hydrolysis of lactose in raw milk： the lactase consumption（E/S）32.06 U / g, the hydrolysis temperature 40℃, pH value 6.82, the hydrolysis time 3.0 h; and further studied the application of the production of low-lactose raw materials such as the main raw materials to produce the old milk drink by this method, its recipe： hydrolysis of lactose skim milk powder 50 g, ethyl maltol 0.3 g, vanillin 0.015 g, sunflower oil 8.25 g, casein phosphorpeptides 9.48 g, xanthan 0.15 g, CMC-Na 0.15 g, water 450 mL.
