GB 7293-2017Feed additive-DL-alpha-Tocopheryl acetate(Powder form) (English PDF)

Foreword

The first chapter of this standard, Chapter 3 and Chapter 5 is mandatory, the rest are recommended. This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 7293-2006 "feed additive vitamin E powder." This standard compared with GB/T 7293-2006, the main technical differences are as follows:

--- Standard name changed to "feed additive DL-alpha-tocopherol acetate (powder)";

--- Increasing the scope of the standard carrier and auxiliary materials requirements;

--- Chemical Name DL-alpha-tocopherol acetate was changed to DL-2,5,7,8-tetramethyl-2- (4,8,12-trimethyltridecyl) -6- benzene Chromanol acetate;

--- The original standard first method (Arbitration Law) column was changed to a capillary column, the internal standard was changed to hexadecanoic acid hexadecanoate;

--- The shelf life of the product made a classification requirements in the provisions of the packaging, storage conditions, organic materials as the carrier of the shelf life For 12 months, inorganic materials as a carrier of the product shelf life of 36 months. This standard is proposed and managed by the National Feed Industry Standardization Technical Committee (SAC/TC76). This standard was drafted unit. Zhejiang Veterinary Drug Feed Supervision, China Feed Industry Association, Shanghai Veterinary Drug Feed Inspection, Zhejiang and new Co., Ltd., Zhejiang Pharmaceutical Co., Ltd. The main drafters of this standard. Zhu Cong Ying, Zhang Zhijian, Qiu Chengjun, Huang Juan, Wang Liwen, Lv Weijun, Shang Jun, Jiang Yin, Yang Jinshu, Shi Dongming, Jiang Hongjun. This standard replaces the standards previously issued as.
