Обзор требований
Этот обзор пока доступен только на английском языке.
Область применения
This standard applies to feed additive L-Valine produced via microbial fermentation using corn, starch, or sugar as primary raw materials. It is mandatory for manufacturers producing and supplying L-Valine for animal feed in China. The standard does not apply to chemically synthesized L-Valine or products intended for human consumption.
Технические требования
The standard specifies the chemical name, molecular formula, and structural formula of L-Valine. It outlines the physical and chemical requirements, including appearance, content purity, loss on drying, and residue on ignition. Manufacturers must ensure their products meet the specified pH and specific rotation limits. Furthermore, the standard sets strict hygiene indicators, including maximum limits for total arsenic and heavy metals (as Pb). GB 10648 is referenced for labeling requirements, ensuring proper identification and safe usage. The document also details the rules for inspection, packaging, transportation, and storage. Compliance with these technical requirements is essential for market access. It specifies that packaging materials must be non-toxic, moisture-proof, and sealed to preserve product quality.
Методы испытаний
The standard describes various testing methods to verify compliance. Identification tests include the ninhydrin method and infrared spectroscopy. The L-Valine content is determined using a non-aqueous titration method with perchloric acid. Other tests cover loss on drying, residue on ignition, specific rotation, and pH. Heavy metal and arsenic levels are evaluated using colorimetric comparison and atomic absorption methods referenced in GB/T 13079-2006.
Частые вопросы
What products are regulated under GB 7300.104-2022?
This standard regulates feed additive L-Valine produced through microbial fermentation using corn, starch, or sugar as raw materials.
What are the key hygiene indicators specified in the standard?
The standard sets maximum limits for total arsenic and heavy metals (as Pb) to ensure the safety of the feed additive.
How is the L-Valine content determined according to this standard?
The L-Valine content is determined using a non-aqueous titration method with perchloric acid standard solution and α-naphtholbenzein as the indicator.
