摘要
选用四种常见的农副产品，即土豆、山药、山芋和菊芋，分别采用三种不同的处理方式，即加水分解、酶解和先加水分解后酶解。然后将各处理液按不同比例添加入调配好的豆浆中，杀菌、冷却、接种、发酵。结果表明，先加水分解后酶解的菊芋滤液对双歧杆菌的促生长作用最为明显，其最适浓度为 0.1％～ 1％， 4h左右可达到发酵终点，比对照明显缩短。产品中的活菌数可高达 10 9CFU/ml。
Four common agricultural products,namely potato,yam,taro and Jerusalem artichoke were chosen for the experiment.They were dealt with water,enzyme and water－ enzyme combined respectively.Then the treated liquid was added to the soybean milk to be mixed well.Sterilization,cooling,inoculation and fermentation were followed.It showed that the filtered liquid of Jerusalem artichoke was the best to promote the growth of the bifidobacterium,and the optimum,concentration was 0.1％～ 1％ and the fermentation cycle was 4 hours or so,shorter than the control.The number of live bacteria could reach 109CFU/ml the product.
