Applicability depends on product scope, certification route, competent authority notices and transition rules. Requst for the translation or verify source before using this record in a compliance decision.
Compliance overview
Scope and applicability
This standard applies specifically to feed additive lactic acid produced through fermentation using starch or sugar-based raw materials via Lactobacillus or Rhizopus oryzae. It is essential for manufacturers and importers of animal feed preservatives and acidity regulators entering the Chinese market. The document establishes the chemical, physical, and hygiene requirements for this specific product category.
Technical requirements
The standard defines the chemical identity of lactic acid (2-hydroxypropanoic acid) and mandates that the product appears as a colorless to yellowish-brown transparent liquid without off-odors. It sets strict physicochemical limits, including thresholds for total acid content, total lactic acid concentration, and the specific ratio of L-lactic acid. Compliance with these chemical parameters is mandatory for product validation. Additionally, the standard regulates the maximum allowable levels of impurities such as iron salts, sulfates, chlorides, reducing sugars, and incineration residue. Heavy metal and hygiene limits are also established for contaminants including total arsenic, lead, chromium, and cyanides to ensure animal safety.
Testing methods
The standard outlines specific analytical procedures, including acid-base titration for total acid determination and High-Performance Liquid Chromatography (HPLC) for quantifying total lactic acid and verifying the L-lactic acid ratio. Impurity levels are evaluated using visual colorimetric and nephelometric (turbidity) comparisons against standard solutions. Heavy metals and cyanides are tested according to referenced national standards such as GB/T 13079 and GB 1886.173.
FAQs
What products are regulated under GB 7300.805-2025?
This standard applies to lactic acid feed additives produced via fermentation using Lactobacillus or Rhizopus oryzae with starch or sugar-based raw materials. It is mandatory for manufacturers targeting the Chinese animal feed market.
How does GB 7300.805-2025 differ from general food additive lactic acid standards?
It is part of the GB 7300 series specifically covering preservatives, mildew preventives, and acidity regulators. It sets distinct physicochemical and hygiene limits for lactic acid used in animal nutrition, differing from general food additive standards.
What are the inspection rules for lactic acid under this standard?
Manufacturers must conduct factory exit inspections for appearance, total acid, total lactic acid, and L-lactic acid ratio. Full type inspections covering all technical and hygiene parameters must be performed at least every six months or upon major production changes.
