1. Main content: Sodium sulfite content is usually required to be ≥ 98%, with high purity to ensure its effective role in food processing, and low impurity content, meeting food safety standards.
2. Iron content: It is generally stipulated that the iron (Fe) content is ≤ 0.005%. Low iron content should avoid adverse effects on food color, flavor, etc., ensuring the quality of food.
3. Heavy metal content: The content of heavy metals such as lead (Pb),  (As), etc. is strictly controlled at extremely low levels. For example, lead content is usually ≤ 0.001%, which meets the strict heavy metal limit requirements of food grade additives and ensures food safety.
4. Water insoluble content: The mass fraction of water insoluble content is generally ≤ 0.02%. A low water insoluble content ensures the solubility and uniformity of the product during food processing, preventing sedimentation and other factors that may affect food quality.
5. Free alkali content: Calculated as sodium carbonate, the mass fraction of free alkali is generally ≤ 0.10%. An appropriate free alkali content helps maintain the chemical stability of the product and avoid significant impact on the acidity and alkalinity of food due to strong alkalinity.

Packaging & Shipping

 

1. Packaging: Food grade packaging materials are used, such as food grade polyethylene plastic bags on the inner layer and kraft paper bags or woven bags on the outer layer, sealed packaging, with a common net weight of 25kg per bag or customized packaging specifications according to customer needs. The packaging is clearly labeled with food additive identification and related usage instructions, production date, shelf life, and other information.
2. Storage conditions: It should be stored in a cool, dry, well ventilated, and clean warehouse. It should be strictly separated from toxic, harmful, odorous, and easily contaminated items to prevent cross contamination. The temperature in the warehouse is generally controlled below 25 ºC, the relative humidity is kept below 65%, and direct sunlight and high temperature environments are avoided to prevent product oxidation and moisture absorption deterioration, ensuring stable product quality and maintaining good performance and safety during the shelf life.

Application

 

1. Food preservation: In the preservation and processing of fruits and vegetables, it can inhibit the growth and reproduction of microorganisms and the activity of enzymes, slow down the oxidation and spoilage rate of food, extend the shelf life and shelf life of food, and maintain the color, flavor, and nutritional content of food well. For example, it is widely used in the preservation treatment of fresh cut apples, lettuce, etc.
2. Food processing aids: In the process of food processing, they can be used as reducing agents to remove oxygen from food, prevent food oxidation, discoloration, flavor change, and loss of nutrients. For example, in the process of wine making, they can be used to prevent wine oxidation and maintain the stability of its taste and color; In the processing of candied fruits and dried fruits, it helps prevent fruit browning, maintain the bright appearance and good taste of the product; In the production of starch syrup, it can have bleaching and antioxidant effects, improving the quality and stability of the syrup.
