摘要: 以光皮木瓜[Chaenomeles sinensis (Thouin) Koehne]果实为主要原料,益生菌为发酵菌种,研制木瓜益生菌发酵饮料,并对发酵前后木瓜汁品质变化进行研究。结果表明,植物乳杆菌及类干酪乳杆菌经驯化后可用于木瓜汁的发酵,复配比例4∶6较为适宜。木瓜益生菌发酵饮料的最优工艺为:发酵温度36 ℃,菌种用量2.5%,发酵时间24 h,在此条件下,活菌数可达8.79 lg(cfu/mL),产酸量为12.2 g/kg。益生菌发酵对木瓜汁的总酸、游离态酚和结合态酚含量影响较大,有利于改善木瓜汁的营养品质,表现为总酸含量增加8.01%,游离态酚增加38.5%,结合态酚减少51.9%。

Abstract: Using Chaenomeles sinensis as raw material, probiotics as fermenting microbe,the fermentation process and quality changes of Chaenomeles sinensis beverage were studied. The results showed that Lactobacillus plantarum and Lactobacillus paracasei could be used for the fermentation of Chaenomeles sinensis beverage after domestication, and the suitable mixture ratio was 4∶6. The optimal fermentation conditions were obtained as follows: Fermentation temperature 36 ℃, inoculation amount 2.5%, fermentation time 24 h. Under these conditions, the number of viable bacteria could be reached 8.79 lg(cfu/mL) and the acid production was 12.2 g/kg. Probiotics fermentation had a great influence on the contents of total acid, free phenol and bound phenol, which was beneficial to improve the nutritional quality of Chaenomeles sinensis beverage. The total acid content increased by 8.01%, the free phenol increased by 38.5%, and the bound phenol decreased by 51.9%.

Key words: Chaenomeles sinensis, probiotics, beverage
