APPLICATION OF THE FATTY ACID ANALYSIS FOR THE ORGANIC COW’S MILK AUTHENTICATION

Confirmation of the authenticity of organic milk is an urgent problem in recent years due to the rapid development of the organic products market. The cattle diet, season, geographical and climatic characteristics of the region can effect on the fatty acid composition of organic and conventional milk. The aim of this work is analysis of the differences in fatty acid composition between organic and conventional milk for the confirmation of the authenticity of organic milk. It was shown that the content of C18:1t11, Conj C18:2 cis-9, trans-11 were higher in the conventional milk, and C18:3n3 ― in organic. This may indicate the decisive influence of the individual components of fodder on the content of each particular fatty acid. The ratio of Conj C18:2 cis-9, trans-11/ C18:2n6 could be used as a potential marker of organic milk authentication
