Champ d’application

This standard applies to feed additive propionic acid products synthesized from propionaldehyde through chemical synthesis and refining. It is specifically categorized under preservatives, mildew preventives, and acidity regulators for animal feed. This standard is mandatory for manufacturers producing propionic acid for the Chinese feed market. It partially replaces GB/T 22145-2008.

Exigences techniques

GB 7300.802-2023 specifies the technical requirements for feed additive propionic acid, covering both physicochemical and sanitary parameters. The standard mandates specific limits for propionic acid content, moisture, relative density, and boiling range. New to this revision are the requirements for evaporation residue, easily oxidizable substances, and aldehyde content, ensuring higher product purity. Sanitary indicators include strict limits for heavy metals such as arsenic and lead. The standard also outlines the criteria for appearance, requiring the product to be a colorless or slightly yellow transparent liquid with a pungent odor and no visible impurities. Compliance with these technical indicators is essential for market access.

Méthodes d’essai

The standard details several testing methods to verify compliance. Propionic acid content is determined using gas chromatography (designated as the arbitration method) or an alternative titration method. Moisture content is measured using the Karl Fischer method as specified in GB/T 606. Other evaluations include tests for relative density, boiling range, and specific chemical analyses for easily oxidizable substances and aldehydes. Heavy metal contamination (arsenic and lead) is assessed according to GB/T 13079 and GB/T 13080.

Questions fréquentes

What products are regulated under GB 7300.802-2023?

It regulates feed additive propionic acid used as a preservative, mildew preventive, and acidity regulator, specifically those produced via chemical synthesis from propionaldehyde.

Are there any updates from the previous version?

Yes, compared to GB/T 22145-2008, this version adds technical indicators for evaporation residue, easily oxidizable substances, and aldehydes, along with their corresponding testing methods. It also modifies the limits for lead and the unit for arsenic.

What are the mandatory factory inspection items?

The mandatory factory inspection items include appearance and properties, propionic acid content, moisture, and aldehyde content (calculated as propionaldehyde).

The summary above provides a high-level overview of GB 7300.802-2023.
