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 L-Ascorbyl-2-phosphate used as a feed additive, specifically products manufactured through the reaction of L-ascorbic acid with metaphosphates (such as sodium, calcium, or magnesium). It is essential for manufacturers and importers of vitamin-based animal feed additives entering the Chinese market. The standard replaces the previous GB/T 19422-2003 and establishes updated regulatory benchmarks.
Technical requirements
The standard mandates specific physical and chemical parameters for the additive. Appearance must be a off-white or pale yellow powder, with a minimum active content threshold of 35%. The active ingredient content must strictly fall within 95% to 110% of the declared value. It also sets a minimum 90% ratio for L-ascorbyl-2-monophosphate relative to the total L-ascorbyl-2-phosphate. Furthermore, the standard imposes strict safety limits on heavy metals and moisture, including maximum thresholds for total arsenic, lead, and total phosphorus. Compliance with these technical indicators is mandatory for batch approval.
Testing methods
The standard outlines rigorous analytical procedures, including an enzymatic hydrolysis method serving as the arbitration method for content determination, and a rapid UV spectrophotometric method. It also mandates High-Performance Liquid Chromatography (HPLC) for determining the specific proportion of monophosphate esters. Additionally, it references established GB/T methods for analyzing heavy metals, such as GB/T 13079 for total arsenic and GB/T 13080 for lead, as well as GB/T 6435 for drying loss.
FAQs
What products are regulated under GB 7300.201-2019?
It applies to L-Ascorbyl-2-phosphate used as a feed additive, specifically products manufactured through the reaction of L-ascorbic acid with metaphosphates (such as sodium, calcium, or magnesium).
Are there any updates from the previous version of GB 7300.201-2019?
The new standard is mandatory and has introduced stricter limits for heavy metals, reducing the maximum allowable total arsenic to 2.0 mg/kg and lead to 10.0 mg/kg. It also added new specifications for total phosphorus and the proportion of L-ascorbyl-2-monophosphate.
How does GB 7300.201-2019 differ from ISO standards?
The standard incorporates its own specific testing methodologies, such as an enzymatic hydrolysis method and a rapid UV spectrophotometric method for content determination, alongside referencing national analytical standards like GB/T 13080 for heavy metal testing.
