about mass technology in analyzing trace toxins and high-throughput screening technique
development. In addition, 16 oral presentations and 68 posters are presented, and awards of
excellent theses were presented at the closing ceremony of the seminar. Through this conference,
the TFDA exchanges analytical techniques and experiences with experts from food-analytical

TFDA actively enhances the analytical technology of illegal food additives. We conduct
the analysis for cross-category food additives with high-resolution mass spectrometry and
the application of the newest international non-target screening technology. We also created
a database of 100 legal and illegal additives such as colorants, antioxidants, sweeteners,

ions and the exact molecular weight of two ion pairs. With the information from the original
database, one test can simultaneously detect 3000 compounds or more, to achieve the goal
of screening cross-category additives. This technology was applied to the 101 post market

surveillance cases of food additives in the beverages, snacks, sauces and processed dried meat
in 2018. In the results, 1 sample is determined the non-compliant sweetener, 3 samples and 8
samples are found the colorants and sweeteners not in the label, respectively. As for the food
random inspections, 8 specimens were detected non-compliant colorants and 4 specimens did
not match the label from a total of 104 specimens of imported products at borders and 32 local
inspection specimens. In the future, we will continuously increase the items with screening
compounds in the database, in order to completely apply the multi-inspection technology for

(1) Development of testing methods for contaminants in food processing
Monochloropropanediol (MCPD) and Glycidyl (GD) are the contaminants be generated
in the process of high-temperature deodorization of oils and fats, which may be digested
in gastrointestinal tract to form Glycidol (GD) and Monochloropropanediol (MCPD). GD
and MCPD are listed as Group 2A and Group 2B carcinogens by the International Agency
