This standard specifies the using principles of additives in food contact materials and their products well as the variety, use scope, maximum level, specific migration limit or maximum residue quantity, total specific migration limit and other limit requirements of their allowable additives.
This standard also includes monomers of some basic polymers or other initiators of polyreaction used during the processing of food contact materials and their products.
2 Terms and Definitions
2.1 Additives in food contact materials and their products
The substances added in food contact materials and their products during the production, which improve or help to improve their quality and characteristics so as to meet the intended use; they also include the processing agents (hereinafter referred to as "additive") added in production process so as to ensure the smooth development of production process other than improving the quality and characteristics of the final products.
2.2 Maximum usage quantity
The maximum allowable quantity of certain kind or type of additive added during the production of food contact materials and their products is expressed in mass fraction (%).
2.3 Maximum residue quantity (QM)
The maximum allowable quantity of certain kind or type of residue in food contact materials and their products, expressed by the amount of residue (in milligram) in each kilogram of food contact materials and their products (mg/kg) or by the amount of residue (in milligram) in each square decimeter of contact area between food contact materials/their products and foods (mg/dm2).
2.4 Specific migration limit (SML)
The maximum allowable quantity of certain kind or type of additive migrating from food contact materials and their products to foods or food simulants contacting them, expressed by the quantity of substance (in milligram) migrating from each kilogram of foods or food simulants (mg/kg) or by the quantity of substance (in milligram) migrating from each square decimeter of contact area between food contact materials/their products and foods or food simulants (mg/dm2).
2.5 Total specific migration limit [SML (T)]
The total maximum allowable quantity of two or more kinds of additives migrating from food contact materials and their products to foods or food simulants contacting them, expressed by the quantity of the specified kind or type of migrated substance (or group) (in milligram) in each kilogram of foods or food simulants (mg/kg) or by the quantity of the specified kind or type of migrated substance (or group) (in milligram) in each square decimeter of contact area between food contact materials/their products and foods or food simulants (mg/dm2).
2.6 CAS No. (chemical abstract service)
Chemical Abstract Service Registry Number.
2.7 Not detectable (ND)
The analyzed target substance shall not be detected out where the analysis method with specified detection limit (DL) is adopted.
2.8 FCA No.
Chinese number of additives in food contact materials and their products.
3 Using Principles of Additives in Food Contact Materials and Their Products
3.1 When the food contact materials and their products contact the foods under recommended use conditions, the level of additive migrating into foods and its impurity level shall not be harmful to human health.
3.2 When the food contact materials and their products contact the foods under recommended use conditions, the additive migrating into foods shall not change the composition, structure or color, aroma, taste, etc. of the foods (unless otherwise specified).
3.3 The quantity of additive used in food contact materials and their products shall be minimized under the premise of realizing the expected effect.
3.4 The used additive shall meet corresponding quality specification requirements.
3.5 The substances listed in GB 2760, where permitted to be used as additives in food contact materials and their products, shall not generate technological function on the foods they contact.
