tailieunhanh - Simultaneous determination of synthetic dyes in gummy candy using novel mesoporous magnetic graphene oxide@zein aerogel followed by a high performance liquid chromatography diode array detector

The present work aimed to determine colorants used as food additives to confirm the gummy candy products authentication using a newly designed adsorbent in magnetic dispersive solid phase extraction. Nowadays, many kinds of synthetic dyes are widely added to food products and should be strictly monitored and regulated like other food additives. | SIMULTANEOUS DETERMINATION OF SYNTHETIC DYES IN GUMMY CANDY USING NOVEL MESOPOROUS MAGNETIC GRAPHENE OXIDE@ZEIN AEROGEL FOLLOWED BY A HIGH PERFORMANCE LIQUID CHROMATOGRAPHY-DIODE ARRAY DETECTOR Samin Hamidi1 Mahboob Nemati2 Farzaneh Lotfipour1 Address es Dr. Samin Hamidi 1 Food and Drug Safety Research Center Tabriz University of Medical Science Daneshgah St. Tabriz 51664 Iran 98 41 33344798. 2 Pharmaceutical Analysis Research Center and Faculty of Pharmacy Tabriz University of Medical Sciences Daneshgah St. Tabriz 51664 Iran 98 41 33344798. Corresponding author hamidisamin@ https ARTICLE INFO ABSTRACT Received 3. 10. 2020 The present work aimed to determine colorants used as food additives to confirm the gummy candy products authentication using a Revised 17. 6. 2021 newly designed adsorbent in magnetic dispersive solid phase extraction. Nowadays many kinds of synthetic dyes are widely added to Accepted 29. 6. 2021 food products and should be strictly monitored and regulated like other food additives. A mesoporous aerogel magnetic graphene Published oxide@zein adsorbent was prepared in a template-free and facile self-assembling manner for magnetic dispersive solid phase extraction extraction of 8 frequently used synthetic dyes in gummy candy samples. The adsorbent was designed and successfully characterized by scanning electron microscopy Fourier transform infrared spectroscopy vibrating-sample magnetometry and Brunauer Emmett Teller Regular article analysis. The isotherm parameters were calculated and the amount of colorant was determined using high performance chromatography. The proposed method was validated according to the FDA guidelines over the concentration range of µg mL. The maximum adsorption capacities of the adsorbent for Tartrazine Quinoline Yellow Ponceau 4R Sunset Yellow Allura Red Carmoisine Indigo Carmine and Brilliant Blue FCF were and mg g-1 .
