Alcance y aplicabilidad

This standard applies specifically to the feed additive zinc glycinate complex, which is chemically synthesized using glycine and zinc sulfate as raw materials. It is mandatory for manufacturers producing and supplying this specific mineral complex for animal feed within China. The document does not cover other types of zinc supplements or non-chelated mineral additives.

Requisitos técnicos

The standard outlines the chemical identity, physical properties, and compositional limits for zinc glycinate complex. It specifies that the product must appear as white or off-white crystalline particles or powder, be soluble in water, and meet specific identification criteria for zinc ions, glycine, and the complex itself. Furthermore, the standard defines strict physicochemical parameters, including minimum content limits for total zinc, total glycine, and the active zinc glycinate complex, as well as maximum thresholds for free glycine and drying loss. It also mandates a minimum particle size passing rate through a specific sieve. In terms of safety, the standard enforces rigorous hygiene limits for hazardous heavy metals. Manufacturers must ensure strict compliance with maximum limits for total arsenic, lead, cadmium, chromium, and mercury.

Métodos de ensayo

The standard prescribes several analytical procedures for verification. Identification tests include chemical precipitation reactions for zinc ions, colorimetric reactions for glycine, and Infrared Spectroscopy (IR) to confirm the complex's molecular structure. Quantitative assessments involve titrimetric and spectrophotometric methods to determine zinc content, alongside an amino acid analyzer method (as the arbitration method) and a Kjeldahl method for total glycine. Heavy metal contamination is evaluated using established atomic absorption and spectrophotometric methods referenced from companion GB standards.

Preguntas frecuentes

What products are regulated under GB 7300.307-2025?

This standard applies specifically to zinc glycinate complex feed additives produced through a chemical reaction using glycine and zinc sulfate as raw materials. It does not apply to other zinc-based feed additives or mineral complexes.

Are there any updates from the previous version of GB 7300.307?

As a newly released document (effective July 1, 2026), it establishes the latest mandatory national specifications for zinc glycinate, including updated chemical formulas, structural requirements, and stringent hygiene limits for heavy metals.

How does GB 7300.307-2025 differ from ISO standards?

The standard heavily references established Chinese national standards (GB/T series) for its testing methodologies. For example, it utilizes GB/T 18246-2019 for amino acid analysis and GB/T 25865-2010 for zinc determination, ensuring alignment with domestic analytical frameworks.
