적용 범위

This standard applies specifically to feed additive Vitamin D3 oil, which is chemically synthesized from wool grease cholesterol, dissolved in vegetable oil, and mixed with appropriate antioxidants. It is not applicable to other forms of Vitamin D3 or non-feed-grade vitamin preparations. Manufacturers producing or exporting Vitamin D3 oily form for animal nutrition in China must comply with this regulation.

기술 요구 사항

The standard establishes mandatory technical indicators for Vitamin D3 oil to ensure product quality and safety. The product specification requires a minimum concentration of 1 million IU/g. Compliance with these chemical and physical limits is strictly enforced for market access. It sets specific thresholds for the active ingredient content, expressed as a percentage of the labeled amount. Additionally, the standard regulates the chemical stability of the oil by imposing strict limits on the acid value and peroxide value, preventing rancidity and degradation. Safety requirements are also defined through maximum limits for heavy metals, specifically Lead (Pb), and Arsenic (As). These contaminant controls are critical for ensuring the safety of animal feed chains. The standard also outlines the required appearance, describing the product as a yellow to brown clear liquid.

시험 방법

The standard outlines rigorous analytical procedures, primarily utilizing High-Performance Liquid Chromatography (HPLC) for the precise quantification of Vitamin D3 content, including the correction for pre-Vitamin D3 conversion. Both normal phase and reverse phase chromatography methods are detailed, with normal phase acting as the arbitration method. Additional testing procedures include spectrophotometry for identification, and referenced methodologies from GB 5009.227 and GB 5009.229-2016 for determining peroxide value and acid value. Heavy metals and arsenic are evaluated using specific colorimetric and wet digestion methods referenced in GB/T 13079-2006 and other national standards. Accurate execution of these testing protocols is essential for batch release.

자주 묻는 질문

What products are regulated under GB 7300.202-2019?

The standard applies to feed additive Vitamin D3 oil synthesized from wool grease cholesterol, dissolved in vegetable oil with antioxidants. It is not applicable to other forms of Vitamin D3 or non-oil-based vitamin preparations.

What are the mandatory requirements for feed additive manufacturers under this GB standard?

It sets mandatory requirements for technical specifications, testing methods, and inspection rules for Vitamin D3 oil. Manufacturers must ensure their product specifications meet at least 1 million IU/g and comply with strict limits for acid value, peroxide value, heavy metals, and arsenic.

How does GB 7300.202-2019 relate to other testing standards?

The standard references several Chinese national standards for testing methodologies, such as GB 5009.227 for peroxide value and GB/T 13079-2006 for arsenic determination. Engineers should review these referenced standards alongside the main text to ensure full analytical compliance.
