消费者日常茶叶饮用习惯对健康的影响

摘要

To understand the status of people's daily tea-drinking,an investigation was carried out on the selection of tea variety,soaking time,drinking habits and drinking volume in Qingdao City.The results showed that there were obvious differences among different consumers in tea type selection,green tea was favored by the highest percentage of consumers,49％ of the total survey number,the order from high to low was:green tea＞ black tea＞ oolong tea＞ pu-erh tea.On tea consumption amount,the proportion of daily consumption of 5 g accounted for the most.Tea soaking of most consumers was usually 3 to 4 times per day,soaking time was generally between 30 s and 50 s.On the daily consumption,most consumers drank 3-6 cups a day.As estimated by six cups of tea,catechin daily intake was 675.0 mg,this value was low,failed to reach the standard healthy tea drinking.The above results showed that Qingdao residents mainly drank green tea,this might be affected by local Laoshan green tea production,the tea consumption was relatively reasonable.But the understanding of health medicinal value of catechin was deficient.In the future,consumers' understanding of drinking tea in a healthy way should be promoted by attaching equal importance to both flavor and healthy contents.%为了解人们日常茶叶消费状况,选择青岛市为研究区域,对普通消费者茶叶种类选择、泡制方法、茶饮习惯和饮用量等进行调查和数据分析.结果显示:不同消费者在选用茶叶种类上存在明显差异,选用绿茶的人群所占比例最高,占调查总人数的49％,从高到低依次为绿茶＞红茶＞乌龙茶＞普洱茶;在茶叶消费量上,每日消费5 g的人群所占比例最高;茶叶浸泡次数大多数消费者以3～4次为主,浸泡时间一般在30～50 s;在茶叶饮用量上以日均饮用3～6杯的消费者居多,以6杯茶估算,每日人均儿茶素摄入量为675.0 mg,这一数值偏低,未能达到健康饮茶标准.以上说明,受青岛市本地产崂山绿茶的影响,饮用绿茶仍然是大多数青岛居民的选择,茶叶消费结构较为合理,但对儿茶素的保健药用价值认识不足,科学摄入量不足,今后应提高人们对科学健康饮茶的认识,形成风味与健康并重的饮荼理念.
