Application

   

 1. Food Industry:
    - It is used as a preservative to inhibit the growth of microorganisms like bacteria, yeasts, and molds, thus extending the shelf - life of food products.
    - It functions as an antioxidant to prevent the oxidation of food components, maintaining the color, flavor, and nutritional value of food. For example, it helps prevent the browning of fruits and vegetables.
2. Beverage Industry:
    - In winemaking, it is added to prevent oxidation and microbial spoilage of wine. It helps to maintain the color and flavor of the wine and can also prevent the growth of unwanted bacteria and yeasts.
    - In the production of fruit juices and other beverages, it is used to preserve the freshness and color of the product by inhibiting oxidation.
3. Textile Industry:
    - It is used in the bleaching process of textiles. It can help to remove excess oxidizing agents and adjust the pH value of the bleaching bath, which is beneficial for achieving better bleaching results and protecting the fabric from damage.
    - It is also used in the dyeing process to improve the dye - uptake and color fastness of fabrics.
4. Paper Industry:
    - In pulp bleaching, it is used to improve the brightness of the pulp by reducing the colored substances in the pulp.
    - It helps to prevent the discoloration of paper during storage and use by inhibiting the oxidation of lignin and other components in the paper.
5. Chemical Industry:
    - It serves as a reducing agent in various chemical reactions. For example, it can be used to reduce metal ions in solution or to convert certain oxidized compounds back to their reduced forms.
    - It is used in the synthesis of other sulfur - containing compounds. It can react with different reagents to form various sulfur - based chemicals that are used in different industrial applications.
6. Photography Industry:
    - It is used in photographic developing solutions to prevent the oxidation of developing agents. This helps to maintain the activity of the developing agents and ensures consistent development results.
