1 Scope
This standard specifies classification, requirements, analysis methods, inspection rules, and marking, packaging, transportation and storage of citric acid for food processing.
This standard is applicable to citric acid products made of starchy materials or sugar-containing materials, and such citric acid is mainly used as sour agent, anti-oxidation synergist and flavouring agent for food processing.
