QB2238 series of chemical standard is divided into project Q2238.1 fortified nutrition heat plan chemical nutrition salt; QH2238.2 nutrition: purification of heart nutrition QB2238.3 porridge and food fortification: QB223R.4 fortified flakes of salt fortification: QB2238.5 fortified nutrition animal nutrition. This standard is the first one of QB2238 series. Chapter 3 of this standard is mandatory, and the rest are recommended. QB2238.22005
This standard is a supplement to QB2238-196 fortified food, and each of the 5 products is divided into separate columns, and the rest are standards. This standard is proposed by China Light Industry Association. This standard is funded by Beijing Jinhai Lake Salt Standardization Center, China National Standardization Center, Hangzhou Shuwan Salt Training Center. The main participants are Chen Suonai, Tong Yue, Zhang Kun, She Dan, Mo Xiuzhi, Wei Yu. This standard was first issued in 1996 and this is the first revision: This standard is compiled from the original light industry standard QB2238-1006 issued by China Light Industry Association. 1 Scope Fortified nutrient salts Zinc fortified nutrient salts QB 2238.22005 Technical standard specifies the requirements, test methods, inspection rules and specifications, packaging, transportation and treatment of zinc fortified nutrient salts. This standard applies to the following food products, including the temperature-sensitive agent for strengthening the nutrition of food. 2 Normative references
