Sodium pyrosulfite is more strongly reducing than sulfite and acts in a similar way to sodium sulfite. China stipulates that it can be used for preserves, cookies, sugar, rock sugar, caramel, candy, glucose, liquid glucose, bamboo shoots, mushrooms and canned mushrooms, with a maximum usage of 0.45g/kg. Residues of preserves, bamboo shoots, mushrooms and canned mushrooms, grapes and black currant concentrate (as SO2) less than 0.05/kg; Biscuits, sugar, vermicelli and other varieties of residue less than 0.1g/kg; The residual amount of liquid glucose should not exceed 0.2g/kg.
【 Use 4 】
Used in food industry as bleach, preservative, loose agent, antioxidant, color protection and fresh-keeping agent.
