Determination of triclosan in foodstuffs

Abstract

A reverse-phase high-performance liquid chromatographic (RP-HPLC) method coupled with an ultraviolet detector was developed to determine triclosan which had migrated into foodstuffs from packaging materials. The method includes extraction with hexane, followed by evaporation to dryness and residue re-dissolution in ACN 90%. Chromatographic separation was performed with a Kromasil 100 C18 column (15 cm x 0.4 cm ID, 5 microm particle size) at 30 degrees C and using ACN and water as mobile phases. Regarding recoveries, good results (higher than 83% and lower than 112%) were obtained for the three representative food matrixes selected (orange juice, chicken breast meat, and Gouda cheese).

Engineering Properties of Polymeric-Based Antimicrobial Films for Food Packaging: A Review

“…Such binding blocks vital biological processes for microbial survival and reproduction [42]. In the second case, triclosan may kill bacteria by altering the synthesis of lipids that form part of the cell wall [33]. Companies that currently offer antimicrobial materials containing Ag are DuPont (USA), Milliken Co. (USA), Surfacine Development Company (USA), and Ishizuka Glass Co. (Japan).…”

“…Current analytical techniques that have been reported for the quantification of triclosan in different environmental matrices include gas chromatography-atomic emission detection, gas chromatography-ion trap mass spectrometry, liquid chromatography-ultraviolet detector, liquid chromatography-mass spectroscopy, chemiluminescence and voltammetric methods [3,4,[9][10][11][12][13][14][15][16][17][18]. These methods are very sensitive and reliable.…”

“…It is also being considered as a possible additive in food packaging polymers and surfaces in contact with foodstuffs in the processing industry [3,4]. TCS may be used for the manufacture of plastic materials and items intended to come in contact with foodstuffs [5].…”

“…LC-MS, unfortunately, is not an available technique in all laboratories. Moreover, LC methods for TCS determination in food matrices with UV detection have also been described [4,42].…”
