Champ d’application

This standard applies specifically to feed additive Vitamin B6 (pyridoxine hydrochloride) produced via chemical synthesis. It is mandatory for manufacturers producing this specific nutritional additive for the animal feed industry in China. The standard does not cover Vitamin B6 products obtained through other methods or intended for non-feed applications.

Exigences techniques

The standard specifies comprehensive physical and chemical requirements for pyridoxine hydrochloride. It defines the product as a white to slightly yellow crystalline powder, odorless with a bitter and sour taste, which is highly soluble in water but insoluble in chloroform or ether. Key technical indicators include strict limits on the active Vitamin B6 content (calculated on a dried basis), pH value of an aqueous solution, loss on drying, and ignition residue. Compliance with these chemical purity parameters is strictly enforced. Furthermore, the standard sets mandatory safety limits for heavy metals, specifically lead (Pb), and introduces new maximum limits for total arsenic (As) to ensure feed safety. The standard also mandates specific identification criteria, including an infrared spectroscopy test to confirm the molecular structure.

Méthodes d’essai

The standard outlines specific analytical procedures, including non-aqueous titration using perchloric acid to determine the active Vitamin B6 content. Identification tests involve chemical color reactions and infrared spectrophotometry. Safety parameters are evaluated using visual comparison methods: heavy metals (Pb) are assessed via a thioacetamide colorimetric method, and total arsenic is determined using an arsenic spot test with mercuric bromide paper. Strict adherence to these specified testing protocols is required for batch release. Other routine tests include gravimetric determination for loss on drying and ignition residue.

Questions fréquentes

What products are regulated under GB 7298-2017?

The standard applies to feed additive Vitamin B6 (pyridoxine hydrochloride) obtained via chemical synthesis. It is mandatory for all manufacturers producing this specific feed additive for the Chinese market.

Are there any updates from the previous version of GB 7298-2017?

Compared to the previous version, this standard upgraded the heavy metal testing method, added infrared identification requirements, introduced total arsenic limits, and removed the melting point parameter.

How does GB 7298-2017 differ from international standards for Vitamin B6?

The standard references Chinese national methodologies, such as using GB/T 9724 for pH measurement and GB/T 14699.1 for sampling. While the chemical identification principles are similar to international practices, overseas manufacturers must strictly follow the GB-specified titration and visual comparison procedures for legal compliance in China.

The summary above provides a high-level overview of GB 7298-2017.
