Particle size analysis of pristine food-grade titanium dioxide and E 171 in confectionery products: Interlaboratory testing of a SP-ICP-MS screening method and confirmation with transmission electron microscopy.
sugar-coated confectionery and pristine food-grade titanium dioxide was developed. Special emphasis was placed on the sample preparation procedure, crucial to reproducibly disperse the particles before analysis. ...
Optimization and validation of an analytical method for the quantification of short- and medium-chained chlorinated paraffins in food by gas chromatography-mass spectrometry
quantification (LOQ s) estimated for food samples ranged from 0.7 to 6.0 ng/g wet weight (ww) for ∑ SCCP s and 1.3–12 ng/g ww for ∑ MCCP s. The applicability of the optimized protocol was assessed in each of the ...
