Application

1. Food Industry
Preservatives: Sodium metabisulfite is commonly used as a preservative in the food industry. It can inhibit the growth of bacteria and mold in food, prevent food from spoiling, and thus extend the shelf life of food. Sodium metabisulfite can play an effective preservative role in meat products, aquatic products, beverages, malt beverages, soy sauce and other foods.

Antioxidant: Sodium metabisulfite is also used as an antioxidant, which can effectively inhibit the oxidation reaction of fat in food, slow down the deterioration of food, and protect the nutritional components and color of food.

Bleaching agent: In food processing, sodium metabisulfite can also be used as a bleaching agent to improve the color of food and make it more attractive. For example, when making sweets such as candy, canned food, jam and preserves, sodium metabisulfite can enhance its shelf life and taste.

Bulking agent: In baked goods, sodium metabisulfite can also be used as a loosening agent to make food softer and easier to chew.

2. Other industrial fields
Chemical industry: used to produce sodium hydrosulfite, sulfadimethoxine, analgin, caprolactam, etc.

Fuel industry catalyst: Sodium metabisulfite can be used as a catalyst in the fuel industry to promote the combustion reaction of fuel and improve combustion efficiency.

Paper industry bleaching agent: In the paper industry, sodium metabisulfite is used as a bleaching agent to remove impurities and pigments in pulp and improve the whiteness and quality of paper.

Dye and textile process additives: In the dye and textile industry, sodium metabisulfite can be used as a chemical additive to help dyes better adhere to textiles and improve dyeing effects.

Photographic industry: In the photographic industry, sodium metabisulfite is used as an ingredient in fixers to help fix photo images.

Spice industry: In the spice industry, sodium metabisulfite can be used to produce flavor ingredients such as vanillin.

3. Other applications
Wastewater treatment: In the electroplating industry, oil fields and other industries, sodium metabisulfite can be used for wastewater treatment to help remove harmful substances in wastewater.

Mineral processing: In the mineral processing process of mineral processing, sodium metabisulfite can be used as a mineral processing agent to help improve the mineral processing efficiency and quality of ore.
