The QB 2238 "Fortified Nutrient Salt" series of standards is divided into five items, and this standard is the fifth item in the QB 2238 series of standards. This standard was first issued in 1996, and this is the first revision. From the date of implementation, this standard replaces the riboflavin fortified nutrient salt part of the light industry standard QB2 238-1996 "Fortified Nutrient Salt" issued by the former China Light Industry General Association. This standard specifies the requirements, test methods, inspection rules and marking, packaging, transportation and storage of riboflavin fortified nutrient salt. This standard applies to fortified nutrient salt with edible salt as the carrier and riboflavin nutrient enhancer added.

5.5.2 Calculation of sodium content
The content of sodium ions is expressed in grams (/100). The calculation method is 5 (1). The calculation method is Na1(g/100g1= C: (g100g>x1.4k:
1.85). The calculation method is 5.6 Riboflavin
5. 6 1 Principle
The sodium ions are yellow and blue. The color depth should be proportional to the riboflavin content. The method is used to measure the sodium ions. 6.2 Instruments and equipment Tester: 5.6 2.2 Spectrophotometer 5.6.3 Agents and solutions 5.6.3.1 General radiation (GE/T1256) 100 g/ml) 5032 General/GH/676) Drop effect: 1.0 mal/ml 5.6 3.3 Standard weight liquid: 250 g/ml 2233.52006
