中文摘要: 该文研究金银花烘青绿茶复合饮料,在单因素试验的基础上,选取金银花和烘青绿茶提取液的混合比例、白砂糖添加量、柠檬酸添加量、L-抗坏血酸添加量为试验因子,以复合型饮料感官审评得分为响应面值,应用响应面设计方法建立数学模型并进行分析。结果表明,4个试验因素对金银花烘青绿茶复合饮料感官审评得分的影响依次为:金银花和烘青绿茶提取液的混合比例>白砂糖添加量>柠檬酸添加量>L-抗坏血酸添加量。获得金银花烘青绿茶复合饮料最佳工艺参数组合为:金银花和烘青绿茶提取液的混合体积比1∶1、白砂糖添加量10.5 g/100 mL、柠檬酸添加量0.13 g/100 mL、L-抗坏血酸添加量0.10 g/100 mL。复合饮料稳定性研究结果显示,当稳定剂选择为海藻酸钠,且其添加量为0.16%时,复合饮料稳定性最佳。在此条件下生产的金银花烘青绿茶复合饮料,具有较好的风味效果。
Abstract:This paper was based on the research about honeysuckle baked green tea compound beverage.According to single factor investigation,the mathematical models which were established and analyzed by response surface design have taked the evaluation score for the senses as the responses,and taked honeysuckle and baked green tea extract mixture ratio,sugar content,citric acid content,L-ascorbic acid content as the experiment factors.The results showed that the effects of four experimental factors on the sensory evaluation of honeysuckle green tea compound beverage were followed by honeysuckle and baked green tea extract mixture ratio>sugar content>citric acid content>L-ascorbic acid content.The best experiment combination factors of honeysuckle baked green tea compound beverage were honeysuckle.Baked green tea extract mixture ratio 1∶1(volume ratio),sugar content 10.5 g/100 mL,citric acid content 0.13 g/100 mL,L-ascorbic acid content 0.10 g/100 mL.The results showed that when the stabilizer was sodium alginate and the content was 0.16%,the stability of the compound beverage got the best.Under this product condition,the honeysuckle baked green tea compound beverage has the better effect on flavor.
