Milk tea milk tea, as its name implies, is "milk" and tea. There are "real milk" and "fake milk" in milk. There are different green tea, black tea and oolong tea in Chaze. ...
There are many questions about the milk tea made in the tea shop, the milk tea bottled in the retail store and the milk tea that wants to hold you in the palm of your hand. Everyone is saying that I don't drink tea shops, so can I drink fragrant xx? On the problem of fake milk (non-dairy creamer).
What exactly is non-dairy creamer?
Of course, the earliest milk tea was milk tea. Later, it was found that milk could be replaced by non-dairy creamer. The obtained milk tea and milk tea made of milk are very similar in appearance and taste, and even provide a better sensory experience after eating, that is, the taste is smoother. In this way, milk tea can be made without milk, and the cost is greatly reduced. People can consume more milk tea with the same money, or a cup of milk tea with less money.
Main components of non-dairy creamer
Hydrogenated vegetable oil, glucose syrup, sodium caseinate, sodium aluminosilicate. Sodium tyrosine is an emulsifier and sodium aluminosilicate is an anti-caking agent. The problem lies in hydrogenated vegetable oil. According to the current process of hydrogenated vegetable oil, most hydrogenated vegetable oil is partially hydrogenated, not completely hydrogenated. Some allyl hydroether terpenoid vegetable oils (PHOS) contain trans fatty acids, and a large number of scientific studies have found that trans fatty acids are directly related to human cardiovascular diseases.
Excessive intake of trans fatty acids will lead to the increase of LDL cholesterol in human blood, which will significantly increase the risk of cardiovascular diseases. When we talk about food safety, we always emphasize one sentence: everything is toxic, and the key depends on the dosage. The harm of trans fats to health is the result of long-term accumulation. As long as you don't eat more, its risk to human health is completely controllable.
How much milk tea can we drink? In 2003, the World Health Organization suggested that the daily energy supply ratio of trans fats should be lower than 65,438+0%. According to the basic energy value of 8400 kilojoules per day for adults, it is equivalent to taking about 2.2 grams of trans fatty acids per day. Therefore, of course, milk tea can be drunk. The main problem is to drink more and drink less. It is imperative to find out how many trans fatty acids are in milk tea. Knowing this data, you can know the answer. We divide milk tea into street milk tea, milk tea cups and bottled milk tea.
Jietou milk tea
If milk is used as milk tea, the trans fat in liquid milk accounts for about 2%~3% of the total fat, and the total fat in whole milk is 3.3. /100.9, the trans fat content in milk is 0.06 ~ 0. 1. /100 g. If half of a 300ml cup of milk tea is milk, the trans fatty acid content in 300ml milk tea is 0. 15.9.
If it is street milk tea made of non-dairy creamer, it depends on the specific content. Referring to the data of a paper "Determination of Trans Fatty Acids in Milk Tea by Gas Chromatography", the content of trans fats in 300ml street milk tea is between 0.5.9 and 2.79.
Brew milk tea with cups in the supermarket. )
The same data source shows that the content of trans fatty acids in a cup of milk tea is between 0.0 12-0.5438+089.
Bottled beverage milk tea (Assam, etc. )
The nutrition label shows that the content of trans fatty acids in a bottled beverage milk tea is zero. It should be pointed out that China's "Food Nutrition Labeling Regulations" has the following provisions on the content of trans fatty acids: when the content of trans fatty acids in food is lower than 0.3.9/ 1009, the label can be marked as "empty knowledge and noisy zero". According to direct data, the content of trans fatty acids in bottled beverage milk tea is 0.3.9/ 100.9 (the actual content may be very low).
Do you know how much milk tea you can drink a day?
Street milk tea is divided into "milk" and "non-creamer". If it is made of milk, you can drink several cups a day, provided that you can drink it (only the intake of trans fatty acids is considered here, and other factors, such as sugar intake and nutritional ratio, are not considered).
However, if you drink milk tea made of non-dairy powder, as shown in the previous data, the content of trans fatty acids in 300ml street milk tea is between 0.5g-2. 19. That is to say, if you drink a 300ml street milk tea made of non-dairy powder, your daily intake of trans fatty acids may exceed the recommended upper limit of 229. Furthermore, if you drink this cup every day for a long time (one year and two years), your blood may be damaged.
If you are crazy about drinking milk tea and feel uncomfortable without a cup every day, you must drink milk-based milk tea (as far as street milk tea is concerned). If you only have a drink once in a while, the hero doesn't ask the source, just buy a drink and plug in a straw to drink as much as he wants.
