recently, there are netizens posted that Wahaha cool crooked, nutrition fast line and other milk-containing beverages, after being yin dry often only a layer of white glue, just like condoms. So, is that really the case?Time: September 18-22Experimental appliances: cool crooked drinks, ordinary yogurt dollower experiments Experiment one: milk-containing drinks 2 days after gel reporters poured into part of the cool crooked into the plate, placed at room temperature naturally dry. Milk-containing beverages look more viscous and flavorful than regular milk.about 12 hours later, the milk-containing beverage is still liquid, failed to reach what netizens called "a dry night of solidification into a gel", but the liquid plane has dropped, indicating that the water has evaporated.the water evaporates faster, the reporter turns on the air conditioner and sets the temperature at 25 degrees C. After another 12 hours, the liquid plane dropped significantly, becoming thicker and thicker, partially solidified, but still able to see the flow of liquid. The reporter decided to put in the air-conditioned environment for another 12 hours. After 12 hours, the drink all solidified, touch much like jelly, is indeed a glue-like substance, these "glue skin" peeled off, and netizen photos almost exactly the same, very sticky, but not elastic, as long as a light pull on the break.experiment two: ordinary milk coagulation is like hard milk sugar all kinds of liquid dairy products on the market including milk, yogurt, milk-containing beverages, etc. , then ordinary milk will not be so? The reporter bought a box of a brand of pure milk, and milk-containing beverages made a comparison experiment.milk is sensoryly thinner and lighter than milk-containing beverages. After 24 hours at room temperature, the milk surface is a layer of skin, similar to "double skin milk", but the milk is still liquid under the skin.12 hours after the milk was released at 25 degrees C, the drop in the milk level was obvious, and the milk skin was still wrinkled, but it was still liquid under the skin. After that, in the 25 degrees C air-conditioned environment for another 12 hours, three kinds of milk and milk-containing beverages as solidified, but the surface of milk coagulant has a lot of folds, and there is a clear sour odor, but milk coagulant than milk-containing beverages that kind of gel is much harder, like hard milk sugar.expert opinion the dehydrated gel of milky drinks is related to additives it is understood that proteins, starches, cellulose, etc. in food, under certain conditions, can be polymerized into glue. Common tofu skins are made using the principle of protein polymerization into glue. "However, some dairy-containing beverages now mostly add some thickeners to improve taste and increase stability." Taizhou Nutrition Society staff said that even if there is no protein, as long as the addition of edible glue, they can also be glued.that thickeners include CMC (methyl cellulose), pectin, guar gum, yellow raw gum and other edible glue.

The main ingredient of milk-containing beverages is water, followed by milk and various additives, its nutritional content is far less than pure milk. Because the milk content is small, this kind of beverage needs to be modulation by adding flavor, sweetener, thickener method, but more than pure milk to meet the taste of children, but excessive intake of additives will increase the burden of human liver, kidney.it is understood that the protein content of fresh milk per 100 ml of emulsion must not be less than 2.5 grams, but most milk-containing beverages can only reach 1 g / 100 ml of protein content.In the means, in China's "Food Additive Use Hygiene Standards" (GB2760-2007), infant formula, larger infant and toddler formula, infant weaning food have made special provisions, in ordinary food, although the use of Ansai honey, sunset yellow, sweets and other food additives, but infant food can not be used.To this end, the industry also said that milk-containing beverages to some extent should not even belong to dairy products, its greatest effect should be better taste and provide moisture, in order to meet the taste, flavor requirements, some milk-containing beverages contain up to 18 kinds of food additives. There are also nutrition experts said that children should be careful to drink milky drinks. At present, many beverage enterprises are generally faced with high-cost, high-risk, low-profit industry situation, in the lactic acid beverage category, only the "milk" ingredients focus, exaggeration, in order to increase the added value of products and bargaining power.Scive Tip Drink milk drinks before meals infect children digestion China Agricultural University School of Food Nutrition and
