火龙果果粒谷物酸奶的研制

Development of Dragon Fruit Grain Yogurt

在谷物酸奶中添加火龙果果粒,以单因素试验和正交试验确定产品配方及发酵时间。感官评分结果表明,牛乳中加入稳定剂(明胶0.1%,果胶0.1%,变性淀粉0.5%)、谷物粉添加量2.0%、白砂糖添加量8.0%,益生菌接种量2.0%,发酵时间5 h时后加入10.0%火龙果果粒,搅拌均匀后再进行降温、冷却,可获得果香浓郁、酸甜可口、凝乳均匀、色泽诱人的火龙果果粒谷物酸奶产品。

Dragon fruit grains were added to cereal yogurt,and the product formula and fermentation time were determined by single factor and orthogonal experiments.The sensory evaluation results showed that the milk was added with stabilizers(0.1%gelatin,0.1%pectin,0.5%modified starch),2.0%grain flour,8.0%white sugar,2.0%probiotic inoculum,and the fermentation time was 5 h.Then add 10.0%dragon fruit granules,stir evenly,and then cool down and cool to obtain a dragon fruit granulated cereal yogurt product with rich fruit aroma,sweet and sour taste,uniform curd,and attractive color.
