| Abstract: | Soybean milk is one of the favourite drinks in China.However,it is vulnerable to microbial pollution extremely for its rich nutrition,which leads to short shelf-life.To solve this problem,this paper considered different combinations of soybean raw materials,simulative pipelines and sterilization methods for finished soybean milk.The results showed the best sterilization way: First of all,soybean raw materials adopted traditional 100℃ water-bath pasteurizing to sterilize for 10 min;Secondly,simulative pipeline was washed by acidic electrolysis of water with the concentration of available chlorine(ACC) at(17±0.5) mg·L-1;Thirdly,the sterilization temperature,sterilization time and additive amount of Nisin was controlled at 100℃,5 min and 0.15 g·kg-1,respectively.Through above sterilization way,all the bacterias in the soybean milk were killed or damaged,ensuring 4 d shelf-life under the condition of 25℃.Besides,we also preliminary identified the toughest bacteria(S) to kill both in the soybeans and soybean milk was Bacillus cereus strain. |
