Sodium metabisulfite is one kind of commonly used food additive, commonly used in food bleaching, sterilization, and oxidation prevention. During use, certain usage standards need to be followed to ensure its safety and effectiveness. The following is an explanation of the standard for the use of sodium metabisulfite in food:
1. Safety standards:
Sodium metabisulfite, as one kind of food additive, needs to comply with relevant national safety standards. According to the Chinese National Food Safety Standard for the Use of Food Additives (GB 2760-2014), the use of sodium metabisulfite should meet the following conditions: the amount of sodium metabisulfite used in each kilogram of food should not exceed 5 grams.
2. Functional standards:
Sodium metabisulfite is mainly used in food processing for bleaching, sterilization, and oxidation prevention. According to processing needs, the amount of sodium metabisulfite used should be appropriate and should not exceed the specified safety standards. It is also necessary to pay attention to the role and effectiveness of sodium metabisulfite to ensure that it can achieve the expected results.
When using sodium metabisulfite, the following points should be noted:
(1) Dissolve sodium metabisulfite in an appropriate amount of water first, and add it to the food after it is completely dissolved.
(2) During use, attention should be paid to avoiding mixing with other food additives to avoid affecting the effectiveness.
(3) After use, it should be stored in a dry, cool, and ventilated place, avoiding direct sunlight and humidity.
In summary, when using sodium metabisulfite, it is necessary to pay attention to safety and functional standards, and correctly grasp the usage method to ensure its safe and effective effect.
