Sodium metabisulfite is a white or slightly yellowish crystalline powder with sulfur dioxide odor. It is a kind of food additive widely used in the food processing industry. It is mainly used to inhibit oxidase in food, prevent oxidation and discoloration of food, and has bleaching effect. In shrimp processing, sodium metabisulfite is mainly used to bleach shrimp shells, making them appear white and improving their sensory quality.

As the leading manufacturer and supplier of Sodium Metabisulfite, Qingdao Tianya Chemical Co., Ltd has been producing and exporting Sodium Metabisulfite for seafood treatment, especially for shrimp.

Sodium metabisulfite mainly achieves bleaching effect in shrimp treatment through the following principles of action:

1. Oxidation-reduction effect: Sodium metabisulfite has strong reducibility and can reduce melanin in shrimp shells, making them appear white.

2. Inhibition of enzyme activity: Sodium metabisulfite can inhibit the activity of melanin synthase in shrimp shells, thereby reducing melanin synthesis.

3. Bleaching effect: Sodium metabisulfite can react with impurities in shrimp shells, making them appear white.

The color of shrimp shells mainly depends on the pigment cells they contain. These pigment cells contain melanin, which gives the shrimp shell color. Sodium metabisulfite, through its strong reducibility, can destroy these pigment cells, thereby achieving the bleaching of shrimp shells. This process not only lightens the color of the shrimp shell, but also improves the sensory quality of the shrimp.

So, how does sodium metabisulfite achieve its bleaching effect? This is related to its unique chemical properties. During shrimp treatment, sodium pyrosulfite can decompose oxidase, inhibit the activity of melanin synthase, and thus reduce melanin synthesis. In addition, sodium metabisulfite can also react with impurities in shrimp shells, generating colorless substances that make the color of shrimp shells lighter.
