Escopo e aplicabilidade

This standard applies to feed additive ferrous glycine complex products synthesized chemically using glycine and ferrous sulfate as raw materials. It is mandatory for manufacturers producing this specific mineral complex for the Chinese animal feed market. The standard does not apply to other mineral complexes or non-synthesized ferrous glycine products.

Requisitos técnicos

The standard specifies comprehensive technical requirements for ferrous glycine complex, including appearance, physicochemical parameters, and hygiene limits. Physicochemical requirements cover categories such as ferrous iron (Fe2+), ferric iron (Fe3+), total glycine, free glycine, complex content, loss on drying, and particle size. Manufacturers must strictly adhere to these parameter limits to ensure product efficacy and safety. Additionally, the standard sets strict hygiene indicators for heavy metals, including total arsenic, lead, cadmium, and mercury. Compared to the previous version, this update introduces new limits for cadmium and mercury, reflecting stricter safety protocols.

Métodos de ensaio

The standard outlines various analytical methods to verify compliance. Identification tests include specific reactions for ferrous ions and glycine. Quantitative analysis utilizes titration methods for iron content and free glycine, while total glycine is determined using the Kjeldahl method or an amino acid analyzer (arbitration method). Heavy metal hygiene parameters are tested according to referenced national standards such as GB/T 13080 for lead and GB/T 13082 for cadmium. Accurate implementation of these testing protocols is essential for batch release.

Perguntas frequentes

What products are regulated under GB 7300.304-2024?

It regulates ferrous glycine complex, a specific feed additive categorized under mineral elements and their complexes. It applies only to chemically synthesized products using glycine and ferrous sulfate.

What are the main updates from the previous GB/T 21996-2008?

The new standard changes from a recommended (GB/T) to a mandatory (GB) status. It updates appearance and lead limits, and introduces new technical indicators and testing methods for cadmium and mercury. It also adds identification tests for ferrous ions and glycine.

How is the total glycine content determined?

Total glycine can be determined using the Kjeldahl method or the amino acid analyzer method. The amino acid analyzer method is designated as the arbitration method in case of disputes.
