DETERMINATION OF VEGETABLE FATS IN FOOD PRODUCTS

Abstract

Tightening control over the quality and safety of food products leads to an expansion of the list of standardized indicators and the regulatory framework of research methods. Despite the lack of established standards and requirements for fatty acid composition (FAC) of meat products and the content of vegetable fats in it, methods have been developed for determining FAC and vegetable fats. The presented approaches to sample preparation make it possible to extract analytes from a sample as quickly and efficiently as possible, and the capabilities of modern analytical equipment make it possible to determine even trace amounts. The lower limit of determination of vegetable fats is 1.0 mg / kg. Ionization by electron impact, in which the molecule of the analyte breaks down into characteristic daughter ions, as well as the use of a library of mass spectra exclude obtaining false or falsepositive results.
