[目的]确定虾青素果汁饮料的最佳发酵条件.[方法]以果汁(西瓜汁、菠萝汁、混合果汁)为原料,法夫酵母为菌种发酵生产虾青素果汁饮料,研究果汁种类、菌体接种量和种龄等对虾青素产量的影响;在此基础上,以果汁加入量、糖浓度、(NH_4)_2SO_4、酵母膏稀释液为考察因素进行正交试验,优化发酵条件.[结果]菌体最佳种龄为48 h,最佳接种量为10%,最佳发酵液为西瓜汁.正交试验结果表明,虾青素果汁饮料的最佳发酵条件为:西瓜汁10%,糖浓度8%,(NH_4)_2SO_4 3%,酵母膏0.1%;在最佳工艺条件下,虾青素的产量较工艺优化前提高了113.2%.[结论]该研究优化了虾青素果汁饮料的发酵条件.
[目的]確定蝦青素果汁飲料的最佳髮酵條件.[方法]以果汁(西瓜汁、菠蘿汁、混閤果汁)為原料,法伕酵母為菌種髮酵生產蝦青素果汁飲料,研究果汁種類、菌體接種量和種齡等對蝦青素產量的影響;在此基礎上,以果汁加入量、糖濃度、(NH_4)_2SO_4、酵母膏稀釋液為攷察因素進行正交試驗,優化髮酵條件.[結果]菌體最佳種齡為48 h,最佳接種量為10%,最佳髮酵液為西瓜汁.正交試驗結果錶明,蝦青素果汁飲料的最佳髮酵條件為:西瓜汁10%,糖濃度8%,(NH_4)_2SO_4 3%,酵母膏0.1%;在最佳工藝條件下,蝦青素的產量較工藝優化前提高瞭113.2%.[結論]該研究優化瞭蝦青素果汁飲料的髮酵條件.

[Objective]The study was to determine the optimum fermentation condition for astaxanthin juice beverage.[Method]The astaxanthin juice beverage was fermented with fruit juice (watermelon juice,pineapple juice and mixed fruit-juice) as materials and Phaffia rhodozyma as strain,and the effects of juice types,inoculation amount and age of cell on yield of astaxanthin were studied.On the basis of that,the orthogonal test was carried out with addition amount of juice,sugar concentration,(NH_4)_2SO_4 and diluent of yeast extract as the investigated factors,and then the fermentation condition was optimized.[Result]The optimum inoculation amount of the cell was 10% with the optimum cell age of 48 h and the optimum fermentation broth of watermelon juice.The results of orthogonal test showed that the optimum fermentation condition for astaxanthin juice beverage was watermelon juice of 10%,sugar concn.of 8%,(NH_4)_2SO_4 of 3%,yeast extract of 0.1%.Under the optimum process condition,the yield of astaxanthin was increased by 113.2% than that before process optimization.[Conclusion]The study optimized the fermentation condition for astaxanthin juice beverage.
