Main Applications
1. Food Processing and Preparation
Caustic Soda is widely adopted in multiple food processing procedures. Fruit and Vegetable Peeling: Caustic Soda is used for chemical soaking and peeling of root vegetables such as peaches, tomatoes, carrots, and potatoes.
Food Color Enhancement and Hardening: In the processing of pickled foods such as olives and pickles, adding Caustic Soda neutralizes acidity and promotes the conversion of chlorophyll into more stable sodium copper chlorophyll, maintaining a bright green color; Caustic Soda also helps maintain the crispness of the fruit flesh.
Grain and Oil Processing: Corn Deep Processing: Caustic Soda is used in the soaking stage of corn starch production to separate protein and starch.
2. In-situ Cleaning of Food Containers
Caustic Soda serves as a core alkaline cleaning agent for food equipment CIP cleaning. Protein and Caramel Removal: Caustic Soda effectively hydrolyzes and removes milk protein deposits, sugar scale, and fat residues from the inner walls of pipes, tanks, and heat exchangers.
Sterilization Assistance: The high-concentration alkaline environment formed by Caustic Soda itself inhibits microbial growth and is often used alternately with acidic cleaning agents (such as nitric acid) to ensure that pipelines meet"sterile"hygiene standards.
3. Water Treatment and pH Adjustment
Caustic Soda plays an irreplaceable role in water quality regulation for food factories and water plants. Drinking Water Adjustment: Caustic Soda is used in water treatment systems of waterworks or food factories to adjust the pH value (acidity/alkalinity) of raw water, reducing its corrosiveness, and assisting in flocculation and sedimentation to remove heavy metal ions (forming hydroxide precipitates).
Packaging Container Sterilization Pretreatment: Caustic Soda is used as a pre-soaking solution during the recycling and cleaning of glass bottles (such as beer bottles and soy sauce bottles), dissolving label adhesives and organic contaminants on the bottle walls.
4. Auxiliary Production of Food Packaging Materials
Although Caustic Soda is not directly added to food, it is crucial in the manufacture of food contact materials: Aluminum Packaging Cleaning: Caustic Soda is used to clean aluminum foil and the inner walls of aluminum cans, removing stretching lubricant and oxide layers from the forming process.
Cellulose Membrane (Cellulose Paper) Manufacturing: Caustic Soda is used to treat wood pulp to produce oil-resistant, transparent, food-grade packaging films.
