中文摘要:

      目的 测定北京某区部分市售奶茶的含糖量, 调查该地区消费者奶茶消费量以及对奶茶含糖量的知识、态度、消费行为及其影响因素。方法 采集市售奶茶样品共40份, 经过预处理后采用酸水解-莱因-埃农氏法检测样品中糖含量(以葡萄糖计)。采用调查问卷和偶遇抽样采集数据。结果 40份样品中, 39份样品的含糖量大于0.5 g/100 mL, 30份样品的含糖量大于5 g/100 mL。调查对象仅有55.5%了解添加糖定义, 仅有36.6%了解《中国居民膳食指南(2016)》中对添加糖的摄入建议。青年人群对添加糖相关知识的知晓情况与减糖行为无关(P>0.05), 能正确评价全糖奶茶含糖量与减糖行为有关(P<0.05), 了解添加糖相关知识与正确评价全糖奶茶含糖量无关(P>0.05)。结论 奶茶消费群体通过奶茶摄入添加糖量较多, 对添加糖相关知识的知晓率也较低, 需要规范奶茶含糖量标注, 加强营养宣传教育。

英文摘要:

      Objective To determine the sugar content of some milk tea sold in a certain district of Beijing, and to investigate the consumption of milk tea, the knowledge, attitude, consumption behavior and its influencing factors. Methods A total of 40 samples of commercially available milk tea were collected. After pretreatment, the sugar content (calculated based on glucose) in the samples was determined by Fehling method. The data were collected by questionnaires and random encounters. Results Among the 40 samples, 39 samples contained greater than 0.5 g/ 100 mL of sugar and 30 samples contained greater than 5 g/100 mL of sugar. Only 55.5% subjects of investigation knew the definition of added sugar, only 36.6% subjects knew the advice on intake of added sugars from Dietary Guidelines for Chinese Residents (2016). The young people's knowledge about adding sugar was not related to sugar reduction behavior (P>0.05), but it was related to correctly evaluating the sugar content of whole-sugar milk tea (P<0.05), and the knowledge about adding sugar was not related to correctly evaluating the sugar content of whole-sugar milk tea (P>0.05). Conclusion The consumption groups of milk tea add more sugar through their intake of milk tea and their awareness of the related knowledge of added sugar is also low. Therefore, it is necessary to standardize the labeling of the sugar content of milk tea and strengthen nutrition publicity and education.
