摘    要:以胡萝卜复合汁为保存基质,分别试验了保存温度、基质的起始pH值、甜味剂、酸味剂和HCl对两歧双歧杆菌存活的影响。结果表明,4℃下保存极显著优于9℃和20℃;基质起始pH6.2、5.0、4.5和4.2时的活菌保存期(活菌数≥10 ̄6cfu/ml)分别为26、13、12和8天;蔗糖和Aspartame对菌体存活无不良影响;柠檬酸对菌体存活的影响程度最大,乙酸最小,乳酸和HCl居中。

关 键 词:两歧双歧杆菌,胡萝卜复合汁,存活

Abstract:The effects of storage temperature.initial pH,sweetening agents and acidulants on the survival of Bifidobacterium bifidum in carrot compound juice(CCJ) were studied.The results indicated that 4℃was the most favorable temperature(p<0.01) for the cells survival comparing with 9℃ and 20℃.When the initial pH of CCJ was adjusted to 6.2,5.0,4.5 and 4.2 by mixed acids of lactic acid and acetic acid (mol ratio 1:1.5),the preservation period(viable cells≥106 cfu/ml) were 26,13,12 and 8 days respectively.The effects of sucrose and Aspartame on the cells survival was insignificant,p>0.05.The most unfavorable acidulants tested was citric acid(p<0.01),lactic acid and hydrochloric acid as the second,acetic acid.the third.
Keywords:Bifidobacterium bifidum  Carrot compound juice  Survival
