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 9454-2008 "feed additive vitamin E".
This standard compared with GB/T 9454-2008, the main technical differences are as follows.
--- The standard name changed from "Feed Additive Vitamin E" to "Feed Additive DL-α-Tocopherol Acetate";
--- DL-α-tocopherol acetate content from ≥ 92.0% modified to ≥ 93.0%;
--- Acidity from the original 1g sample consumed 0.1mol/L sodium hydroxide shall not exceed 2.0mL revised to 1g sample consumption
0.1mol/L sodium hydroxide can not exceed 1.0mL;
--- Increased health indicators arsenic requirements and the corresponding determination method;
--- Increased specific rotation and peak identification;
--- The original standard first method (Arbitration Law) only retained by capillary gas chromatography, column packed gas chromatography was removed, and the internal standard more
Hexadecanoate to hexadecanoate;
--- Capillary gas chromatography chromatography conditions increased shunt ratio 20. 1, flow rate was changed to 2mL/min, column temperature was changed to 270 ℃ ~
280 ° C;
--- Factory inspection from "all the indicators specified in this standard for the factory inspection items" to "Chapter 3 listed in the project, the appearance and character,
DL-α-tocopheryl acetate content, refractive index, specific rotation, absorption coefficient, acidity and tocopherol as the factory inspection items. "
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. Zhang Zhijian, Wu Yubo, Zhu Congying, Ren Yuqin, Zhou Fengchao, Shi Xingfen, Wu Wang, Jiang Yin, Yang Jinshu,
