Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces SN 0339-1995 "toxin B1 aflatoxin testing method tea for export", SN 0637-1997 "export oilseeds, Kennedy
Fruit and nut products for aflatoxin testing method of liquid chromatography "and SN 1101-2002" Importers aflatoxin in cereals and oilseeds
Test methods "toxins.
This standard SN 0339-1995, SN 0637-1997 and SN 1101-2002 compared to, in addition to editorial changes, the main technical change
Of the following.
--- Modify the standard Chinese name, standard name changed to "food for export Determination of aflatoxin residues in the" standard English name
Called modified accordingly;
--- Measurement matrix extended to maize, tea, peanut fruit, peanuts and bitter almond;
--- Removed SN 0339-1995 in the purification process and pre-column derivatization;
--- The first method HPLC added immunoaffinity chromatography purification method, derived from an increase of actinic after liquid chromatography column
Science and electrochemical derivative derived in two ways;
--- Removed SN 1101-2002 second method thin layer chromatography.
This standard is proposed and managed by the National Certification and Accreditation Administration Committee.
