Experts reveal the inside story of fake artificial tofu, claiming that there are loopholes in regulations that cannot be managed

A few days ago, the tofu produced by a company in Suzhou was found to be fraudulent in Wuhan. The company used soybean protein isolates, modified starches, white pigments and other synthetic tofu, and produced and sold fake foreign brands. To the surprise of industrial and commercial personnel, on the counterfeit products, in addition to the company's name, address, and hygiene license number, etc., which are consistent with the company’s products, the packaging bags also have unique laser anti-counterfeit labels on their authentic products. "The value of this laser plate-making machine is about 8 million yuan. It can be seen that the scale of the printing plant providing bags is quite large," said Suzhou factory personnel.

One Zhou surname worker explained that the soybean protein isolate, soybean oil, modified starch, salt, and monosodium glutamate were mixed at a certain ratio on site, stirred by a mixer, then added with ice cubes and pigments to continue stirring, and put into the steamer after being filled into the mold box. Steamed and finally packaged. The reporter saw on the scene that the bean curd made with soy protein isolate is somewhat similar to frozen tofu and contains a lot of pores. Soybean protein isolate is a kind of protein supplement produced from low-temperature dehydrated soybean meal. It is often used in beverage, nutrient food, fermented food and other food industries. Modified starch is a modified edible starch, and "white pigment" is a non-toxic, odorless white powder, commonly used in food whitening.

Artificial eggs are not new to the public. Now there is artificial synthetic tofu. Recently, the industrial and commercial department in Hubei seized processing dens for artificial tofu. Yesterday, the reporter interviewed the relevant person in charge of the Municipal Soybean Products Industry Association. She disclosed that she had also found suspicious artificial tofu on some stalls in the urban area of ​​the island. For this reason, she gave the public a few tips on purchasing soy products.

What is the normal tofu of bean curd soybean milk? Is artificial tofu counted as tofu, is it harmful to the human body? Yesterday, the reporter interviewed Yu Dianxiang, president of the Municipal Soybean Industry Association. Yu Dianxiang told reporters that the traditional method of tofu in the north was to use soybeans to grind soybean milk and then add brine or seawater. This tofu contains high-quality protein and has the functions of lowering blood pressure, lowering blood fat and lowering cholesterol, both raw and cooked. It can be suitable for both young and old. “The raw materials of traditional bean curd are soybeans, brine and a small amount of defoamers. Defoamers account for two thousandths of the total, requiring cleaning, soaking, refining, rejecting slag, baking at temperatures above 100 degrees Celsius, and spotting brines.”

Synthetic tofu has no "law" management "I have seen synthetic tofu reported on television. I have previously found suspected tofu on some of the stalls in the urban area of ​​the island." Yu Dianxiang believes that artificial tofu should not be considered tofu, "use The tofu made from starch, salt, monosodium glutamate, etc., basically has no bean flavor, and its nutritional value certainly cannot keep up with real tofu."

Yu Dianxiang said that the country has not defined the broad concept of tofu. As far as the current market is concerned, including soft tofu and dried bean curd, the applicable production standards are the “non-fermented soybean products” national standards that were implemented on January 1, 2009. The premise of this standard must be: soy products made from pulping process. That is, if it is a bean product made by other processes, the standard does not bind it.

Small workshop abuse additives Yu Dianxiang said, according to the traditional practice, under the normal circumstances of the next kilogram of beans can be two pounds six two tofu, but some small workshops in order to more tofu, an additional coagulant, so that a pound of beans can produce four pounds tofu. Now that soybeans cost about 2.2 yuan per catty, the cost of a pound of tofu in traditional practice is more than two yuan, but after the addition of coagulant, the cost has fallen below two yuan.

Yu Dianxiang told reporters that there are at least hundreds of small tofu workshops in Qingdao. The phenomenon of using coagulants is very common. The coagulant is an additive that can play a role in water absorption and solidification. “The process of making tofu is too low, so now many small workshops, large companies simply can not beat a small workshop.” Yu Dianxiang said that their association has done statistics before, Qingdao daily tofu sales in more than 20 tons, we The sales of regular manufacturers still accounted for less than half of the market, and the rest were occupied by small workshops.

The artificial tofu has a real taste. The real tofu has a slightly yellowish color and the surface is uneven. There are soy aromas. The Soybean Industry Association reminds the public that when buying soy products, do not buy tofu that is too white or yellow in color. Soybeans have oil and gas, soy bean curd color is slightly yellow, the surface is not very smooth, there are some small eyes; and artificial tofu, the surface is very smooth and delicate. Unusually whitish tofu is added with a solidifying agent. Its yellowish color is all yellow and it is caused by the addition of pigments.

Traditional tofu has a certain degree of elasticity, and its softness and hardness are moderate. It smells like there should be a scent of beans. Synthetic tofu has poor elasticity because of the use of soy protein isolate, the smell is very light, even the taste of chemical agents, and because it contains a large number of additives, long-term consumption will cause harm to the human body.

In addition, under normal circumstances, tofu is fragile, but if you see very "spiritual" white tofu, or tough tofu, then you have to be careful.
