Escopo e aplicabilidade

This standard applies to feed additive sodium diacetate products manufactured through the reaction of acetic acid and sodium hydroxide or sodium carbonate. It is intended for use as a preservative, mildew preventive, and acidity regulator in animal feed. Manufacturers and importers of feed additives containing sodium diacetate must comply with this standard. It does not apply to other types of feed additives or chemically distinct preservatives.

Requisitos técnicos

The standard outlines the chemical identification of sodium diacetate, including its molecular formula (C4H7NaO4) and relative molecular mass. It specifies appearance and physical properties, requiring the product to be a white crystalline powder with a specific acetic acid odor. Regarding physicochemical parameters, the standard sets minimum limits for sodium acetate and acetic acid content on a dry basis, alongside maximum thresholds for moisture and formate/easily oxidizable substances. It also defines the acceptable pH range for a standard solution. Furthermore, the document establishes hygiene and safety limits for heavy metals and total arsenic to ensure product safety for animal consumption. Compliance with both physicochemical and hygiene limits is mandatory for market approval.

Métodos de ensaio

Testing protocols include visual and olfactory inspection for appearance, and flame tests plus chemical reactions for ion identification. Quantitative analysis of sodium acetate is performed via potentiometric titration using perchloric acid, while acetic acid content is determined by acid-base titration with sodium hydroxide. Moisture content is measured according to the Karl Fischer method (GB/T 6283), and heavy metals are evaluated using a turbidimetric method (NY/T 4689).
