Born to a poor family, he would turn up to school in a suit of homespun cloth and consume his lunch of homemade pretzels, washed down with a bottle of homogenized milk. 他生在一个贫困的家庭,到学校来会穿着用家里纺织的布做的衣服,吃的午饭是自制的松脆椒盐饼干,就着喝一瓶均质牛奶。
Ultrasonic homogenized milk is mostly steady in acid producing and easy to control in the process of fermentation. 用超声波均质奶、高剪切均质奶和非均质奶在相同的配方和制作工艺下制作酸奶,经超声波均质的牛奶在发酵过程中比其它两种奶产酸稳定,易于控制。
