Food additives for who stole the black pan

From the earliest white cakes, Sudanese reds to melamine, protein concentrates to this year's fluorescent whitening powder, these substances are added to foods, so many people think that these are food additives, which in turn make it extremely bad Impression, even talk about "Tim" discoloration. In fact, it is a food additive that is backed by illegal additives.

There are overuse and over-range use of food additives.

Talking about the use of food additives in reality, Associate Professor Zhu Yi of the College of Food Science and Nutritional Engineering of China Agricultural University explained that there are currently three major problems. The first is to use illegal additives as food additives, and in addition to food additives. Excessive use, there is the use of over-range.

Food additives are allowed by the country to be added to foods. The Food Safety Law clearly specifies which can be added, including the amount added. However, Sudan Red, Hang Bai Bai and the like are not included in the national food additives, and are illegal additives. At present, there are two common types of illegal additives: First, chemical raw materials used in foods are strictly prohibited as food additives, such as paraffin wax pot bottoms; second, food-grade additives are replaced with industrial-grade additives. Sodium bicarbonate used in the product.

Associate Professor Zhu Yi, for example, said that fluorescent brighteners that have been stirred up in the recent past are illegal additives. Fluorescent brighteners are physical brighteners that use the complementary color principle. The normal light shines on the mushroom with the fluorescent whitening agent added. Besides increasing the reflectivity of the mushroom, it can absorb the invisible light in the ultraviolet region. After absorbing the ultraviolet region light, it emits a blue-green light. In the process of transportation and storage, mushrooms are damaged, browned and become brownish-brown. At this time, the tan light and the blue light will become white in visual effect. Fluorescent brighteners are used in a wide range and can be said to be ubiquitous. This material is present in the clothes we wear, in the writing paper, and so on. However, this substance is not allowed to be used in food and is therefore an illegal additive.

In addition to the abuse of illegal additives, the excessive use of food additives is also worthy of caution. On the Internet, a netizen who claimed to have done a fried chicken business revealed such a dark scene. “In the beginning, according to the method of head office teaching, the taste of chickens and ducks that were blown out was always inferior to theirs. After listening to the instructions of relevant people, they learned that they used traditional pepper, aniseed, dried tangerine peel, and cinnamon. In addition to the 20 kinds of botanical ingredients, the real content is the bone marrow paste, tender meat powder, leavening agent, color enhancer, flavoring agent, and sweetener added to about 100 chickens (a type that is 60 times sweeter than saccharin. There are also some brown materials containing poppy powder, and dozens of chemical and industrial substances that can't figure out what it is, such as adding crispy additives. In particular, the bone marrow paste is soaked for about 8 hours. Chickens and ducks are saturated with scent in their bones, and in the end, 5 kg of monosodium glutamate is put in. In this way, when people eat it, they feel that the bones are very crispy and have a strong aroma, and they can't forget to eat and eat. It is incredible that the smell is very fragrant, is an oil-like preparation with good volatility, pour some of the oil used in fried chickens and ducks every day, when the oil heats up, at 200 meters or even more In far places, people can hear "
