What is the ratio of sodium metabisulfite for food additives?

National standard: In the 80s, the state once formulated a relatively loose standard, that is, the sulfur dioxide residue can reach 2% to 2% In 2003, the national standard was changed and changed to, but many companies can't do this, because if you don't add so much sodium metabisulfite, then in the end it is easy to rot and mold, so you have to add so much. Later, after coordination, it finally became, but this standard, many enterprises cannot meet it.

Use. The chemical and pharmaceutical industries are used for the production of insurance powder, sulfadimethylpyrimidine analgin, caprolactam, etc., as well as chloroform, phenylpropylsulfone and benzaldehyde purification. It is used in the photographic industry as an ingredient for fixers.

The fragrance industry is used in the production of vanillin. It is used as a preservative in the brewing industry, a rubber coagulant and a dechlorinator after bleaching cotton cloth. Organic intermediates, dyes, tanning are used as reducing agents in the electroplating industry, wastewater treatment in oil fields and as beneficiation agents in mines.

industrially used in printing and dyeing, organic synthesis, printing, tanning, pharmaceutical and other departments; It is used as a preservative, bleaching agent and loosening agent in food processing.

It is used as a chemical reagent (printing and dyeing and photography, etc.), as a bleaching agent, mordant, reducing agent, rubber coagulant, and also used in organic synthesis, pharmaceuticals and spices.

Sodium metabisulfite is mainly used in biscuits, and mainly plays a role in destroying gluten in biscuits, making biscuits more crispy. According to GB2760-2007 "Hygienic Standard for the Use of Food Additives", the maximum amount used in biscuits is: Therefore, be careful not to exceed the standard during use.

Summary. China stipulates that it can be used for preserves, biscuits, sugar, rock sugar, starch sugar, candy, glucose, liquid glucose, bamboo shoots, mushrooms and canned mushrooms, and the maximum amount of use.

Dear, wait a minute, I'll answer for you right away.

China's crude and high liquid regulations can be used for candied fruit, biscuits, sugar, Bingnian vertical sugar, starch sugar, candy, glucose, liquid Portuguese sugar, bamboo shoots, mushrooms and canned mushrooms, the maximum amount of use.

The residual amount of candied fruit and dust, bamboo shoots, mushrooms and canned mushrooms, grapes and blackcurrant juice concentrate (in terms of SO2) was less than; The residue of biscuits, sugar, vermicelli and other varieties is less than; The residual amount of liquid glucose must not be exceeded.

Excuse me, how much is Jiao Ya also large?

GB2760 has clear regulations, specifically refer to the Xiang Kaoli Noodles, a safe dosage of sodium metabisulfite in food is per 25kg of food, Jiaoya can only put 1g.

Food grade sodium metabisulfite is a food additive that is generally used to maintain the freshness and color of food. It can be used in a variety of foods, such as preserved fruits, canned eggplant, candies, raisins, etc. However, different countries and regions may have different regulations for the dosage standards of food-grade sodium metabisulfite, so it needs to be used according to local regulations.

Taking China as an example, the following is the relevant information about the dosage standard of food-grade sodium metabisulfite. 1.The maximum amount of sodium metabisulfite used in food China has strict regulations on the use of sodium metabisulfite.

According to GB 2760-2014 "National Food Safety Standard for the Use of Food Additives", the maximum use of sodium metabisulfite in all kinds of food shall not exceed the following values:- Canned fruits, preserved fruits, candied fruits: g kg.

Pastries and cakes: g kg. - Catering Condiments:

g/kg。- Condies and chocolate products: g kg.

Raisins and jujube products: G The label declaration of sodium metabisulfite in food requires that when sodium metabisulfite is used as a food additive, according to the provisions of GB 7718-2011 "National Food Safety Standard General Principles for Food Labeling", the name of sodium metabisulfite or "sulfite" must be indicated on the food label, and its corresponding function must be indicated, and the dosage must be declared in accordance with the maximum use standard specified in GB 2760-2014. 3.

Scope of application of sodium metabisulfiteAlthough sodium metabisulfite is an additive widely used in food, not all foods are suitable for use. According to the provisions of the "GB 2760-2014 National Food Safety Standard for the Use of Food Additives", sodium metabisulfite is suitable for sweet and sour taste, preserved fruits, canned fruits, preserves, jelly, meat floss, jellyfish, olives and other food products, in addition to candy and chocolate products. In general, the dosage and scope of application of food-grade sodium metabisulfite are strictly regulated.

Manufacturers must use it in accordance with the relevant standards, and at the same time pay attention to avoid excessive use. In addition, when purchasing food containing sodium metabisulfite, consumers should also carefully check the ingredient and dosage labels on the label and follow the correct way to consume them.

Summary. The dosage of sodium metabisulfite should meet the requirements of GB1893, and 5% sodium metabisulfite solution should be configured for drinking water for aquatic preservation. The dosage of sodium metabisulfite solution is 1:10 to the mass ratio of aquatic products. Spray evenly on the surface of the fish with a watering can.

The dosage of sodium coke type rent sulfite should meet the requirements of GB1893, and the drinking water for aquatic preservation should be equipped with 5% sodium metabisulfite solution. The ratio of sodium metabisulfite solution to the quality of aquatic products is 1:10. Spray evenly on the surface of the fish with a watering can.

The dosage is in, according to different products, the addition amount is not the same. Please refer to the national standard GB-2760-2011 national food safety standard; It is inevitable to add filial piety additives in food, and national standards and regulations should be strictly implemented.

Hope mine can help you, thanks.
