適用範囲

This standard applies to feed additive ferrous lactate produced from specific raw materials such as sodium lactate (or calcium lactate) and ferrous sulfate, or lactic acid and iron powder. It is mandatory for manufacturers producing this specific mineral complex for animal feed in China. The standard does not apply to other types of iron-based feed additives or human food grade ferrous lactate, which are covered by GB 1903.47-2020.

技術要求

GB 7300.309-2025 specifies the technical requirements for ferrous lactate used as a feed additive. It defines the chemical name, molecular formula, and structural formula to ensure accurate product identification. The standard sets strict physicochemical indicators, including minimum content requirements for ferrous lactate (on a dry basis), and maximum limits for ferric iron (Fe3+), moisture, chlorides, and sulfates. It also mandates specific pH ranges and particle size fineness for the powder. Additionally, the standard establishes hygiene indicators to ensure safety, setting maximum limits for heavy metals such as lead and total arsenic. Compliance with these limits is essential for market access. The document also outlines requirements for labeling, packaging, transportation, and storage to maintain product integrity, referencing GB 10648 for feed label compliance.

試験方法

The standard outlines various testing methods to verify compliance. Identification tests for lactate ions and ferrous ions are conducted according to GB 1903.47-2020. Content determination, moisture analysis, and heavy metal testing (lead and total arsenic) are performed using specified national standard methods. Manufacturers must follow these exact testing protocols to ensure valid batch inspections. Particle size fineness is measured using a two-layer sieve method as per GB/T 5917.1.
