Compliance overview
Scope and applicability
This standard applies to feed additive nicotinic acid obtained through chemical synthesis. It is specifically designed for products used in the animal feed industry and does not cover naturally extracted or biologically fermented nicotinic acid. Compliance with this standard is mandatory for manufacturers producing synthetic nicotinic acid for feed applications in China. The standard replaces the previous version GB/T 7300-2006 and introduces new requirements such as total arsenic limits.
Technical requirements
The standard specifies comprehensive physical and chemical requirements for feed-grade nicotinic acid. Appearance-wise, the product must be a white or off-white powder with specific solubility characteristics. Key technical parameters include the nicotinic acid content (calculated on a dry basis), which must fall within a strictly defined percentage range. The standard also sets limits for melting point and loss on drying. Furthermore, the standard imposes strict maximum limits for various impurities and heavy metals, including ignition residue, heavy metals (as Pb), total arsenic (As), chlorides (as Cl), and sulfates (as SO4). Manufacturers must ensure their products meet all these chemical purity thresholds to be considered compliant. The standard also outlines general rules for labeling, packaging, transportation, and storage, specifying a shelf life of 24 months under proper conditions.
Testing methods
The standard outlines several analytical procedures to verify compliance. Identification tests include colorimetric reactions and ultraviolet-visible spectrophotometry to confirm the substance's identity, alongside infrared spectrophotometry compared against a reference spectrum. For quantitative analysis, the standard provides two methods for determining nicotinic acid content: the perchloric acid potentiometric titration (serving as the arbitration method) and a neutralization titration method. Impurity testing involves specific procedures for measuring loss on drying (via reduced pressure drying), ignition residue, and limit tests for heavy metals, total arsenic, chlorides, and sulfates using visual colorimetric comparison against standard solutions.
FAQs
What products are regulated under GB 7300-2017?
GB 7300-2017 regulates feed additive nicotinic acid produced via chemical synthesis. It sets the mandatory technical specifications, testing methods, and labeling requirements for this specific product entering the Chinese animal feed market.
Are there any updates from the previous version of GB 7300-2006?
Yes, GB 7300-2017 replaced GB/T 7300-2006. Key updates include the deletion of the HPLC method for content determination, revisions to the testing methods for heavy metals and loss on drying, the addition of total arsenic limit requirements and testing, and a revised shelf life.
Is GB 7300-2017 a mandatory standard?
Yes, Chapters 1, 3, and 5 of GB 7300-2017 are mandatory, while the remaining chapters are recommended. This means the technical requirements, scope, and inspection rules must be strictly followed by manufacturers.
