China Seeks Public Comments on Draft Standard for Food Nutritional Fortifier 5??Phosphorylated Pyridoxal

Chinese authorities have released a draft national food safety standard titled Food Safety National Standard Food Nutritional Fortifier 5??Phosphorylated Pyridoxal for public consultation, aiming to establish unified quality, safety, and testing requirements for this vitamin B6?derived fortification ingredient.The draft standard, issued under the national GB food safety standard framework, applies to 5??phosphorylated pyridoxal produced through chemical synthesis using pyridoxine hydrochloride as the raw material. Once finalized, it will serve as the authoritative regulatory basis for production, quality control, and market supervision of this nutritional fortifier in China.
Scope and Substance Identification-According to the draft, the standard is applicable to food nutritional fortifier 5??phosphorylated pyridoxal, a biologically active form of vitamin B6 widely used in fortified foods and special dietary products.
The document clearly defines the substances:
1.Sensory Characteristics Requirements
The draft sets out basic sensory quality requirements to ensure product uniformity and acceptability. Under the proposed standard, 5??phosphorylated pyridoxal must:
Appear off?white to light yellow in colour
Be in the form of a crystalline powder
Be free from visible foreign matter
2.Physicochemical Quality Specifications
One of the core components of the draft standard is the establishment of quantitative physicochemical indicators. Key requirements include:
Content (on a dry basis): 98.0%102.0%
pH value (2.5 g/L aqueous solution): 2.63.0
Moisture content: Not more than 9.0%
In addition, the draft introduces strict impurity controls, limiting:
Any single impurity peak to no more than 1%. The total impurity content to no more than 2%
These limits are intended to ensure product purity and consistency, particularly given the compounds sensitivity to light, oxygen, and oxidative conditions.
Heavy Metal Safety Limits
To strengthen consumer safety, the draft standard sets maximum limits for heavy metal contaminants:
1.Lead (Pb): ? 1.0 mg/kg
2.Total arsenic (as As): ? 1.0 mg/kg
The inclusion of detailed analytical protocols is intended to ensure uniform implementation across inspection bodies, testing laboratories, and manufacturers.
