on January 10, 2005 (G/TBT/N/CHN/77). The notification allows 60 days
for comments. All comments from interested U.S. parities should be sent

## BEGIN TRANSLATION

# Foreword

The technical requirements in Chapter 4 of this Standard are mandatory,
the others are recommended.

The technical requirements of this Standard adopt the fourth edition of
the American Food Chemicals Codex (FCC IV, 1996) in an equivalent
manner.

This standard revises GB 13509 - 1992 "Food Additive - Xylitol".

Major technical differences between this Standard and the original
standard GB 13509 - 1992 are as follows:

\- to cancel the index of total alcohol content from the physical and
chemical indexes, and adds the index of lead content;

\- to raise the index of Xylitol content, strictly limit the indexes of
loss on drying, other polyhydric alcohols and reducing sugar, and amend
the index of melting point;

\- to determine the content of Xylitol by using gas chromatography (GLC)
(arbitration method) or liquid chromatography (HPLC).

This Standard is presented by the China National Light Industry
Associations

This standard resides in the National Food & Fermentation
Standardization Center.

Hebei Baoshuo Co., Ltd. Xyfur Branch, Shandong Yucheng Futian Pharmacy
Co., Ltd., Henan Huixian County Hongtai Chemical Co., Ltd. Xylitol
Branch, Beijing Jianli Pharmaceutical Co., Ltd., Zhejiang Pharmaceutical
Co., Ltd. and China National Academy of Food and Fermentation Industries
are in charge of drafting this Standard.

This Standard is drafted mainly by Wu Jibiao, Zhu Lujia, Lu Zhinuan,
Wang Ping and Li Huiyi.

This Standard was first promulgated in 1992.

The original edition superceded by this Standard is GB 13509 - 1992.
