Appendix A
(Informative)
Guidelines for Food Safety Control Requirements of Different Food
Additive Production Forms
Food additives come from a wide range of sources, including food ingredients, non-
food ingredients, even hazardous chemicals. Meanwhile, the production forms and
production processes of food additives are very complicated and diverse; which mainly
include chemical reaction methods, natural raw materials extraction methods from
animals and plants, biological fermentation methods, physical mixing methods, and
the like basic methods, as well as the cross-over and mixed use of the above methods.
Appendix takes examples to propose corresponding control requirements for different
forms of food additive production; so that provide guidelines and assistance for the site
selection, plant and production process layout, cleaning area determination of food
additive enterprises; in actual production, it can be implemented by referring to the
product characteristics, production process, and the like factors; see Table A.1 in
details.
A.1 According to the different forms of food additive production, equipment and
facilities characteristics, set up the corresponding factory; establish corresponding
food safety control system; ensure its implementation and improvement.
A.2 Regardless the forms of production, the package, storage, transportation of final
food additive products can ensure the quality of food additives and prevent the cross-
contamination; be able to ultimately ensure the hygiene and food safety of the final
food products.
