GB 9454-2017Feed additive -- DL-��-tocopheryl acetate (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 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-alpha-Tocopherol Acetate";

--- DL-alpha-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 °C ~

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-alpha-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.
