GB 7300.201-2019Feed additives - Part 2: Vitamins,provitamins and chemically well-defined substances having similar effect - L-Ascorbyl-2-phosphate (English PDF)

Foreword

Chapters 1, 3, 4, and 5 of this part are mandatory, and the rest are recommended. GB 7300 "feed additives" is divided into several parts by product. This section is Part.201 of GB 7300. This section is drafted in accordance with the rules given in GB/T 1.1-2009. This section replaces GB/T 19422-2003 "feed additive L-ascorbic acid-2-phosphate", compared with GB/T 19422-2003 The main technical changes are as follows:

--- Increased product specifications (see 3.2);

--- Increased the L-ascorbic acid-2-phosphate ester content item index, which is set to 95% ~ 110% of the indicated amount (see 3.4);

--- Increased the indicator of the ratio of L-ascorbic acid-2-monophosphate to L-ascorbic acid-2-phosphate (see 3.4);

--- Increased the total phosphorus index (see 3.4);

--- Modify the total arsenic content <=5.0 (mg/kg) to <=2.0 (mg/kg) (see 3.4,

3.2 of the.2003 version);

--- Modify the lead content <=30.0 (mg/kg) to <=10.0 (mg/kg) (see 3.4,

3.2 of the.2003 version). Please note that some elements of this document may involve patents. The issuer of this document is not responsible for identifying these patents.

1 Scope

GB 7300.201-2019 is the Chinese national standard on feed additives - part 2: vitamins,provitamins and chemically well-defined substances having similar effect - l-ascorbyl-2-phosphate, in the field of agriculture. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 17 December 2019 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 July 2020. Classification: ICS 65.120, CCS B46. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This part of GB 7300 specifies the technical requirements, test methods, inspection rules and requirements for feed additive L-ascorbic acid-2-phosphate ester salt. Labeling, packaging, transportation, storage and shelf life. This section applies to the L-ascorbic acid-2-phosphate ester prepared by the reaction of L-ascorbic acid with metaphosphate (sodium, calcium, magnesium, etc.).
