中文摘要: 以绿茶、雪梨为原料制成绿茶-雪梨果味茶饮料,通过响应曲面法获得最佳制作配方。通过对绿茶的浸提所得 茶汤与鲜榨梨汁按一定比例混合得到绿茶-雪梨混合茶饮料。因鲜榨雪梨汁均易在常温与氧气反应发生褐变,故采用柠 檬酸做护色剂并采取预煮方法进行物理护色。制作工艺以茶-水质量比、茶汤-梨汁体积比、白砂糖添加量、柠檬酸添加 量、pH 值 5 个试验变量因素,以色泽、透明度、气味、味道 4 个因素作为感官评价标准进行五组单因素实验,对所得数据 进行响应曲面法,通过对等高线图分析得到二者条件交互影响情况,得到最佳配方:绿茶-雪梨汁体积比为 1.25 ∶ 1,柠檬 酸添加量为 0.13 %,白砂糖添加量为 6.86 %,所得混合饮料色泽明亮,透明度高,气味香甜,口感宜人。

Abstract:To make green tea and snow pear fruit tea beverage using green tea and snow pear as raw materials and obtain the optimum formula by response surface method. To mix the extraction of green tea and fresh pear juice together according to a certain proportion to make green tea and snow pear fruit tea beverage. Since fresh pear juice became easily oxygen-reaction-brown at room temperature, citric acid was used as a color-protect- ing agent and a physical color-protecting method was taken. The study took mass ratio of tea to water, green tea and snow pear volume ratio, sugar dosage, citric acid dosage and pH value as experiment factors to make five-single-factor-experiments according to sensory evaluation standard: color, transparency, flavor and taste, then response surface methodology were applied to investigate the experimental data. Though analysis of contour lines and response surface, the optimum formula of green tea and snow pear tea fruit beverage were achieved simulta- neously when green tea and snow pear volume ratio was 1.25 : 1, citric acid addition was 0.13 %, sugar adding amount was 6.86 %, and green tea and snow pear fruit tea beverage had wonderful color and taste delicious.
