GB7300.101-2019
Feed additives—Part 1：Amino acids, their salts and analogues—L-Threonine
饲料添加剂 第1部分：氨基酸、氨基酸盐及其类似物 L-苏氨酸
GB 7300.101-2019 is a current mandatory Chinese national standard for Feed additives—Part 1：Amino acids, their salts and analogues—L-Threonine. It appears in the Food compliance cluster with a product safety focus and has an implementation date of Jul 1, 2020.
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 to feed additive L-Threonine produced via fermentation and extraction processes using starch-based or sugar-based raw materials. It is mandatory for all manufacturers importing or producing this amino acid feed additive in China. It replaces the previous GB/T 21979-2008 standard.
Technical requirements
The standard mandates specific physical and chemical parameters for L-Threonine. It requires the product to appear as a white to light brown crystalline powder, odorless and soluble in water. Key technical indicators include strict limits for L-Threonine content (calculated on a dry basis), specific optical rotation, and loss on drying. Furthermore, the standard enforces critical safety thresholds for heavy metals (as Pb) and total arsenic (as As), alongside a newly introduced pH value parameter for a 1% aqueous solution. Compliance with these chemical and physical limits is essential for market access.
Testing methods
The standard outlines rigorous testing procedures to verify compliance. Identification tests include the ninhydrin reaction and infrared absorption spectroscopy, referencing the Chinese Pharmacopoeia. Content determination of L-Threonine is performed using potentiometric titration with perchloric acid. Additional testing methods cover specific optical rotation measurement, loss on drying, ignition residue, pH value, and colorimetric comparison for heavy metals. Manufacturers must ensure their quality control labs are equipped to perform these specific analytical procedures.
FAQs
What products are regulated under GB 7300.101-2019?
It applies to feed additive L-Threonine produced via fermentation and extraction processes using starch-based or sugar-based raw materials. It is mandatory for all manufacturers exporting or selling this specific amino acid product in China.
Are there any updates from the previous version of this standard?
It replaces GB/T 21979-2008. Key updates include modified requirements for L-Threonine content, heavy metals (Pb), and total arsenic (As), the addition of a pH value parameter, and revised shelf-life requirements.
How does this standard differ from international standards?
The standard references Chinese pharmacopeia methods and national standards (e.g., GB/T 13079 for arsenic). Manufacturers should ensure their testing protocols align with these specific Chinese methodologies to prove compliance.
The summary above provides a high-level overview of GB 7300.101-2019.
