光合细菌功能型胡萝卜汁饮料的研制

Preparation of function carrot beverage with photosynthetic bacteria

研制一种含益生菌——光合细菌的胡萝卜汁饮料。以胡萝卜为主要原料,采用正交试验和感官评定指标确定果汁饮料的加工工艺和最佳配方。最佳配方为胡萝卜汁15%、白砂糖8%、柠檬酸0.10%、稳定剂0.10%,其中稳定剂为羧甲基纤维素钠(CMC-Na):黄原胶=1:1。使用的光合细菌菌种为沼泽红假单胞菌,果汁饮料中添加细菌浓度≥1×107cfu/mL。该饮料呈橙红色、口感良好、营养丰富,还具备一定保健功效。

This research paper involves a new formula and the processing technology of fruit beverages.Photosynthetic bacteria as a probiotic has been developed using carrots as a primary raw material.A sensory and orthogonal test evaluation was employed as well.The successful formula has been determined.The following ingredients have been introduced into the formula,15% pure carrot juice,8% granulated sugar,0.10% citric acid,0.10% stabilizer：sodium carboxymethylcellulose/xanthan gum=1：1,Rhodoseudomonas Palustris was introduced into the beverage as the photosynthetic bacteria.The concentration of cultured bacteria was≥1×10 7 cfu/mL.The best production is orange and taste good,has rich nutritional value for health.
