Identification record
Sampling
14 out of 20 milk tea samples claim 'sugar free'
Nandu reporter simulated that consumers placed 20 online black milk tea orders from physical stores through the Internet, with prices ranging from 10 yuan to 25 yuan. Sugar free or unsweetened is required except for a few who do not have a 'sugar free' option. 14 of the 20 milk teas claim to be 'sugar free'. In order to ensure the rigorous and scientific experiment, the content of each milk tea should be greater than or equal to 1000m L. therefore, each milk tea should be purchased 2 cups.
Subsequently, a total of 40 cups of 20 milk teas were sent to Guangdong Provincial Food Inspection Institute for the composition inspection of caffeine, total sugar, fat and trans fatty acids. According to the engineer of Guangdong Food Inspection Institute who is responsible for the inspection, in order to test the content of the ingredients in milk tea, sample pretreatment must be carried out. First, milk tea is poured into the grinder to make milk tea and Pearl stir and mix evenly, which is convenient for sampling and testing, and the results are more rigorous.
Testing
Total sugar:
14 kinds of milk tea are sugar free
Or because there is no distinction between the concept of "no sugar" and "no sugar"
Among the 20 milk teas, 14 claimed that they were sugar free, but the total sugar content of each milk tea was 4.45-24.5g, the lowest was "Ye tea", the lowest was "Ye tea", the highest was "coco can" pearl milk tea, the average content was 14.8g
Why is sugar content of some sugar free milk tea higher than that of micro sugar or milk tea with no special requirements for sugar content? According to the engineer, referring to the requirements of "sugar free" in GB 28050-2011 national standard for food safety general principles for nutrition labeling of prepackaged food, 14 milk tea claims that "sugar free" does not meet this requirement. This may be due to the lack of consideration of technical factors, or the lack of clear distinction between the concepts of "sugar free" and "sugar free", and the lack of full consideration of whether the raw and auxiliary materials contain sugar.
Generally speaking, moderate consumption of milk tea is not a big problem for consumers' health. It is suggested that consumers, especially young consumers, should not drink too much milk tea.
According to the data of total sugar detection, the content range of 20 cups of milk tea total sugar (calculated by glucose) is 4.45-32.5g in 500g / cup, and the average content of each cup is 17.9g. According to 2 cups of milk tea per day, the average intake of sugar reached 35.8g, which exceeded the recommended intake in the dietary guidelines.
It is reported that there is no corresponding national standard for sugar free beverages, but in GB 28050-2011 national standard for food safety general principles for nutrition labeling of prepackaged food, it is stipulated that the '0' limit value of sugar (lactose) should be & le; 0.5g/100g, that is to say, the sugar content of 'sugar free' products should be & le; 0.5g/100g. Results after testing, 14 milk tea samples with nominal 'sugar free' were tested for sugar content All of them are higher than 0.5g/100g, and the sugar content of the nominal sugar free ccoco pearl milk tea is 4.9g/100g, which is 9.8 times of the reference standard. According to the engineer, there is no ingredient list and label in this batch of samples, and some businesses may make too simple product description due to insufficient consideration of technical factors or insufficient understanding of product concept when they are not sure whether the raw materials contain sugar.
Caffeine:
Mandarin duck milk tea has the highest content
Small possibility of business addition
The results showed that caffeine was detected in all samples, with the content range of 125-728m g / kg. The highest content was Hong Kong Mandarin Duck milk tea, with the highest content of 728m g / kg.
The results also showed that there was no significant difference in caffeine content in 20 milk teas, ranging from 100m g / kg to 300mg / kg. The caffeine in milk tea mainly comes from the tea in the formula. The caffeine content of each tea is different, and the caffeine content of milk tea is also different.
Usually, the caffeine content of each cup of tea is only half of that of each cup of coffee. The official website of a well-known foreign brand coffee shows that the caffeine content of a brand instant coffee is about 240-320mg / kg, while the data of the U.S. Department of agriculture shows that the caffeine content of tea drinks is 46-280mg / kg. In this test, the average caffeine content is 243mg / kg, and the median value is 213mg / kg, which is equivalent to the content of tea drinks, less than instant coffee. Engineers said that from the existing test results, the caffeine content in milk tea samples is close to the background value of ingredients, so it is unlikely that the merchants intentionally add caffeine.
Experts say moderate caffeine intake is not bad for adults. But children, pregnant women, patients with hypertension or heart disease and other special groups should avoid excessive drinking, otherwise it may cause similar anxiety symptoms, such as hypertension, palpitation, tremor, sleep disorders, etc.
Fat:
Dietary guidelines recommended daily fat intake
A cup of milk tea can take up nearly 30% of the total
Fat is a common component in dairy products, which can bring good flavor and taste, but excessive fat intake can easily lead to obesity. Fat detection data showed that the fat content of 20 cups of milk tea ranged from 0.1g/100g to 3.9g/100g, with an average content of 2.5g/100g; calculated by 500g / cup, the fat content of each cup of milk tea ranged from 0.5g to 19.5g, with the highest content of '1 little bit' milk tea, the lowest content of 'early generation' iced tea, with an average fat content of 12.3g per cup of 20 milk tea
In terms of fat intake, according to the reference intake of dietary nutrients for Chinese residents (2013 Edition), the fat intake per day should account for 20% - 30% of the total energy intake (adult residents aged 18-49 years). The dietary guidelines for Chinese residents suggest that the energy intake per day for light manual workers is 2250kcal for men and 1800kcal for women. Based on the average energy intake of 2025kcal, 1g of fat can provide 9kcal of energy（ Calories), then the recommended intake of fat in a day is 2025 & times; 30% / 9 = 67.5g. The test results show that the cup of milk tea with the most fat content can provide 19.5g fat, accounting for nearly 30% of the recommended intake of fat in an adult's day, and the average fat content of each cup of 20 milk tea also reaches 18% of the recommended intake
Excessive fat intake is prone to obesity, which may also lead to the occurrence of some chronic diseases. The Chinese dietary Guide (2016) advocates food diversification and residents' habit of cultivating light diet. Therefore, it is not recommended for consumers to drink milk tea frequently and in large quantities.
Trans fatty acids:
6 trans fatty acids detected
Eating often or increasing the risk of coronary heart disease
According to the engineer, there are two kinds of trans fatty acids. One is natural trans fatty acid, which is very low in dairy products. No research has shown that it is harmful to human body. The other is non natural trans fatty acid, which is more stable than ordinary vegetable oil, has the advantages of high temperature resistance, not easy to deteriorate, long storage, etc. compared with animal oil, the price is lower, which can play the same effect as natural cream, but is harmful to human health.
In this test, six milk teas were detected as trans fatty acids, which are: 'dacasse' pearl milk tea, 'siyunnaigaigong tea' pearl milk tea, 'yukegong tea' brand pearl milk tea, 'Yidian' milk tea, 'yecha' fish pond tea milk, 'mixue ice city' pearl milk tea. The lowest content of "Ye Cha" fish pond tea milk is 0.05g/500g, and the highest is "Da Kasi" pearl milk tea, which is 0.9g/500g. According to the Chinese dietary guidelines (2016), it is recommended that the intake of trans fatty acids per person per day should not exceed 2G. According to the Engineer, calculated by 500g per cup of milk tea, the content of trans fatty acids in each cup is between 0.05g-0.90g, which is lower than the limit of 2G, so for the trans fatty acids in milk tea There is no need to worry too much about acid.
However, according to the intake of 0.90g/cup and 2 cups / day, the daily intake of trans fatty acids is close to the limit of 2G. 'if we consider the intake of other foods that may contain trans fatty acids, such as cakes and biscuits, people who consume a large amount of milk tea still have the risk of trans fatty acid intake exceeding the limit', the engineer added: 'regular consumption may increase the incidence of coronary heart disease and cardiovascular and cerebrovascular diseases, and excessive intake of trans fatty acids by pregnant or lactating women may also affect the development of infants, because It is recommended that each person consume no more than one cup of milk tea per day.
