Usage
Uses: mainly used as reducing agent for printing and dyeing, bleaching agent for pulp, linen, oil, etc., and for pharmaceutical, analytical reagents, etc
Sodium hyposulfite is more reductive in sulfite bleach. The maximum amount used for preserves, dried fruits, dried vegetables, vermicelli, glucose, sugar, crystal sugar, caramel, candy, liquid glucose, bamboo shoots, mushrooms and canned mushrooms is 0.40g /kg. The residual amount is measured by sulfur dioxide, bamboo shoots, mushrooms and canned mushrooms shall not exceed 0.5 5g/kg; Sugar, vermicula and other varieties shall not exceed 0.1g /kg; Liquid glucose shall not exceed 0.2g /kg; Candied fruit shall not exceed 0.05g /kg. Residual content of potato powder (S02) ≤0. 05g/kg.
