This standard specifies the technical requirements, test methods, packaging, marking, storage and transportation and delivery acceptance of paraffin for food. Who is this standard applicable to use oil-containing wax as raw material? , food paraffin obtained by sweating or solvent deoiling, and then hydrorefining or clay refining. According to use, it is divided into food paraffin and food packaging paraffin. Food paraffin is suitable for use in pharmaceutical components of food, demoulding, tableting, lighting and other waxes that are in direct contact with food and medicine. Food packaging paraffin wax is suitable for impregnation of containers and packaging materials in contact with food, as well as wax for drug sealing and coating. 2 Reference standards
