It can be said that milk tea has huge profits.
Second, be wary of some milk teas with excessive pigmentation
Recently, the Shenzhen Municipal Market Supervision and Administration Bureau found that 15 batches of 20 batches of samples had the phenomenon of adding food additives to the sunset yellow beyond the range, and it can be said that there are serious safety risks in the tea industry. After discovering this phenomenon, the Shenzhen Market Supervision and Administration Bureau quickly organized a two-month special rectification action. Why is there a serious safety hazard in tea drinking? What is Sunset Yellow? Let's make it clear to you today.
What is Sunset Yellow?
Sunset yellow is actually a kind of food coloring, and the food coloring in our daily life can be divided into two categories: natural pigments and synthetic pigments. Natural pigments are extracted from animal and plant tissues and microbial cells, such as chlorophyll, β-carotene, pepper pigment, lycopene, zeaxanthin and so on. Natural pigments are expensive to produce, and the quality is easily affected by metal ions, water quality, PH value, oxidation, light and temperature, and the coloring power is not high. On the contrary, synthetic pigments are inexpensive, bright in color, strong in coloring, and stable in nature, so they are widely used in food production. There are as many as 21 kinds of synthetic pigments approved for use in China, including carmine, which has been frequently mentioned in previous years, and today's protagonist sunset yellow.
What are the dangers of adding sunset yellow beyond range?
Most of the food synthetic pigments are synthesized from chemicals such as benzene, toluene and naphthalene, and synthesized by a series of chemical reactions such as sulfonation, nitrification and azo, so most of them also have certain toxicity and can affect human health. Taking sunset yellow as an example, if people eat a large amount of it for a long time or at one time, it may cause allergies, diarrhea, damage to the liver and kidneys, and may also cause cancer. Therefore, China's "Sanitary Standards for the Use of Food Additives" (GB2760) stipulates that sunset yellow shall not be used in tea beverages, and the maximum amount of use for other food additives is 0.10g/kg.
How to drink summer tea correctly?
Although tea drinks have been found to be out of the range of food additives, does this indicate that tea drinks cannot be drunk? Nor is it, first of all, to control the amount of drinking, although the tea is delicious and delicious, but the drinking should be moderate, not excessive. Secondly, when buying tea, priority is given to drinks made on the spot and juiced with fresh fruit. In addition, because the synthetic pigment is brightly colored, it can be preliminarily judged whether to add it through the color of the tea, and do not blindly pursue tea drinks with abnormally bright colors or too different from the color of raw materials when purchasing.
Written in the end, the current incidence of diabetes, high blood lipids, hypertension in China is on the rise, and the proportion of young people is increasing, one of the major reasons is related to a large number of drinks of these sugary, high calorie tea, coupled with the safety hazards of the tea market, here is advised to drink less!
