Teach you to recognize food additives

Food additives are substances added for technical purposes in food manufacturing, processing, adjustment, handling, packaging, transportation, and storage. Food additives, as an auxiliary ingredient, may directly or indirectly become food ingredients, but they cannot affect the characteristics of foods. They are substances that do not contain pollutants and do not improve food nutrition.

The second batch of "non-edible substances that may be illegally added in foods" published by the Ministry of Health includes: leather hydrolysates, potassium bromate, beta-lactamase, and dimethyl fumarate.

Leather hydrolysates - foods that may be added: Dairy products, milk-containing drinks As the name suggests, this illegal additive is the process of hydrolysis of leather by chemical means. Since the main component of animal skins is protein, the hydrolysate is called leather hydrolysis. Proteins, added to foods, increase protein content. Unlike melamine, melamine, although commonly known as "protein essence", is not a real protein. The use of melamine is a hole in protein detection methods. Leather hydrolysates are real proteins. If they are added to dairy products and milk beverages, they are detected. It is more difficult to get up than melamine. The hazard of this leather hydrolyzate is that its raw materials are mainly from the corner wastes of the tannery factories, and the leather corner wastes often contain potassium dichromate and sodium dichromate. The raw materials used to produce hydrolyzed protein are natural. Into the product, absorbed by the body can lead to poisoning, make joints loose and swollen, harming human health.

Potassium bromate - foods that may be added: Flour, flour products Early studies showed that mice fed on brominated bread for up to two years did not show any signs of increased risk of oncological or oncological disease. Through research on brominated breads, it was found that bromate was transformed into harmless bromide in the baking process. However, Japanese research has opened up the true colors. Baking tests showed that approximately 50 parts per billion of bromate remained in baked bread. In 1983, the experiment was conducted on mice fed with potassium bromate solution. The final conclusion was that potassium bromate was carcinogenic to rats under the experimental conditions. When the results of the trial were announced, the International Agency for Research on Cancer classified potassium bromate as a carcinogen. In a 1992 report by the World Health Organization (WHO), it was inappropriate to use potassium bromate as a flour treatment agent. The results of relevant tests showed that potassium bromate is a carcinogen. Sensitive test methods have confirmed that bromate is still present in bread when potassium bromate is used in the treatment of flour at a level that is considered permissible. However, because potassium bromate has the characteristics of increasing gluten strength, whitening flour, and making poor-quality flours that are easily fermented into bread when it is fermented into bread, it is not easy to collapse, and it is inexpensive, so potassium bromate is still added as a non-food substance by a small number of producers. in.

Beta-lactamases - Foods that may be added: Dairy products, especially "no milk"

Beta-lactamase, as an antibiotic decomposer in milk, was first introduced by scientific researchers as a research result and has a long history. This practice can effectively break down residual beta-lactam antibiotics in milk. But the risk of using beta-lactamase to break down antibiotics in milk is that, first, the safety of beta-lactamase and whether it can be added to foods are not yet conclusive; second, after decomposing beta-lactam drugs, The introduction of other harmful substances; Third, this practice connives the abuse of antibiotics during the feeding of dairy cows.

Dimethyl fumarate - Foods that may be added: Pastries, moon cakes, and spicy snack foods Dimethyl fumarate is a new type of anti-mildew anti-staling agent developed in the United States in the 1980s. Microspore is a dibasic unsaturated fatty acid ester that inhibits more than 30 molds, yeasts, fungi, and bacteria. It is particularly effective against Clostridium botulinum and Aspergillus flavus. Studies have shown that the antibacterial property of dimethyl fumarate is not affected by the pH value, the antibacterial effect is long, the effect is good, and it has the characteristics of high efficiency, low toxicity, economical and practical, etc. Therefore, it is a new type of antiseptic that has been received both at home and abroad. The food and feed industries attach great importance and are used for the anti-mildew, anti-corrosion, anti-insect, and fresh-keeping of food, beverage, feed, Chinese herbal medicine, cosmetics, fish, meat, vegetables, fruits and other products. Dimethyl fumarate is mostly found in baked goods. Using its fumigation and antibacterial properties, the sublimated dimethyl fumarate will form a gas-inhibiting, small space, but the risk is that many people have this type of volatility. Gas allergic reaction. Therefore, China has banned its use.

Some food additives are legal but have safety concerns:

Preservatives, product name: sodium acetate. Such as: cheese, cheese, butter, margarine (oil food). Possible Health Effects: Teratogenicity.

Antioxidants, product name: BHA, BHT. Such as: fat, instant noodles, chewing gum, cheese, butter. Possible Health Effects: BHA is identified as a carcinogen and some BHT studies have shown to be carcinogenic.

Artificial sweetener, product name: saccharin, sweetener. Such as: candied fruit, melon seeds, pickled pickles, drinks. Possible health effects: It has been shown by animal tests that it causes bladder cancer.

aspartame. Such as: beverages, chewing gum, candied fruit, sugar substitutes. Possible health effects: Dizziness, headaches, epilepsy, irregular menstruation, impaired metabolism of the baby (people with phenylketonuria can not eat).

Color retention agent, product name: nitrite. Such as: sausage, ham, bacon, bacon, duck, dried fish. Possible health effects: Combines with amines in food to form carcinogenic nitrite amine salts.

Bleach, product name: sulfite. Such as: candied fruit, dehydrated fruits and vegetables, golden needles, shrimp, rock sugar, fresh salads of fruits and vegetables, starch. Possible health effects: May cause urticaria, asthma, diarrhea, vomiting, and cases of death from asthma.

Synthetic pigments, product name: yellow on the 4th. Such as: biscuits, candy, oil noodles, pickled yellow radish, ham, sausages, drinks. Possible health effects: The oil industry product - coal char as raw material synthesis, there are many opportunities for the mixing of harmful substances, its own strong toxicity, there are hidden concerns of carcinogenicity, can cause urticaria, asthma, allergies.

Bactericide, product name: hydrogen peroxide (hydrogen peroxide). Such as: tofu, dried beans, vegetarian chicken, pasta, fish paste, meat products, dead chicken (bleached and deodorized). Possible health effects: Stimulate the gastrointestinal mucosa. Eating too much may cause headache, vomiting, and carcinogenicity. The provisions of the food must not be left, not as bleach.

Foot Warmer is also named as Heating Boot, as it looks like a boot in the shape.

It has a fashionable design, hence it is also a good choice as a promotional gift.

In the cold winter, foot warmer is a best choice for keeping warm. When the feet are warm, the entire human body warms up quickly.

It also has a controller with adjustable heat settings, as well as the auto shut off function.
