GB/T 11425-2008Oil of cassia, China (English PDF)

Foreword

This revised standard adopts ISO 3216:1997 "Chinese cinnamon oil." And ISO 3216:1997 as compared to the main technical differences are as follows.

--- Remove the ISO 3216:1997 method of sampling;

--- Test Methods "Common test methods for spices of" national standards;

--- ISO 3216:1997 specified trans-cinnamic aldehyde content of 70% to 88% of the standard 74% -88%;

--- The ISO 3216. 4.10 1997 as the content of this standard Annex B (informative);

--- Increased inspection rules;

--- For signs, packaging, transportation, storage and shelf life of the contents of specific provisions.

This standard replaces GB/T 11425-1989 "cinnamon." this standard compared with GB/T 11425-1989, the main changes are as follows.

--- Deleted taste indicators;

Determination --- trans-cinnamic aldehyde content by area normalization method instead of the internal standard method;

--- Added Appendix B representative and characteristic component content range.

This standard Annex A, Annex B is informative appendix.
