Abstract

Introduction. There are several important aspects requiring a control of fatty acid composition in drinking milk distributed across the retail stores: milk is one of the main consumer products; fatty acids are the main energy substrates, involved in the synthesis of cellular structural components, whereas their interaction might impact the intensity of body growth and development; the fatty acid composition of milk varies depending on the diet and the animal's specific physiological state; in case of udder diseases, a change milk composition may occur; prevention of product counterfeiting distributed across the retail stores.  Material and methods. The present research examined milk samples from five dairy producers that distribute their products across the retailing chains in Kyiv. Milk samples were collected to determine the fatty acid composition. Milk fat was extracted following the Folch method. The milk fatty acid content assessment was carried out by gas chromatography.  Results. 20 fatty acids were identified in the tested milk samples. A higher level of saturated fatty acids was recorded in milk from "Ferma" and "Selyanskoye for kids" dairy producers. The highest content of unsaturated fatty acids was registered in products of “Ukrainskoe” and “Molokia” dairy trademarks.  Conclusions. The fatty acid composition of the drinking cow’s milk distributed across trading networks in Kiev was found to be heterogeneous, by differing in the content of both long-chain saturated fatty acids and unsaturated fatty acids.

Highlights

There are several important aspects requiring a control of fatty acid composition in drinking milk distributed across the retail stores: milk is one of the main consumer products; fatty acids are the main energy substrates, involved in the synthesis of cellular structural components, whereas their interaction might impact the intensity of body growth and development; the fatty acid composition of milk varies depending on the diet and the animal's specific physiological state; in case of udder diseases, a change milk composition may occur; prevention of product counterfeiting distributed across the retail stores
Differences between the compared indicators were considered reliable at a significance level of P≤0.05, P≤0.01. As it has already been mentioned above, the fatty acid composition of consuming milk, distributed across the retail chains, depends on many f2a0ct2o0rs associated with both the quality of raw material supplied to the dairy processing plants and the depth of processing, namely, the technologies used by different dairy manufacturers
The fatty acid composition of Ferma dairy brand (2.5% fat content) contained the highest amount of fatty acids with a chain length from C4:0 to C16:0 (59.33%) as related to the lowest fatty acids content ranging from C17:0 to C22:0, compared with the relative content of the corresponding fatty acids in selected milk samples of other dairy brands

Summary

Introduction

There are several important aspects requiring a control of fatty acid composition in drinking milk distributed across the retail stores: milk is one of the main consumer products; fatty acids are the main energy substrates, involved in the synthesis of cellular structural components, whereas their interaction might impact the intensity of body growth and development; the fatty acid composition of milk varies depending on the diet and the animal's specific physiological state; in case of udder diseases, a change milk composition may occur; prevention of product counterfeiting distributed across the retail stores. The present research examined milk samples from five dairy producers that distribute their products across the retailing chains in Kyiv. Milk samples were collected to determine the fatty acid composition. A higher level of saturated fatty acids was recorded in milk from "Ferma" and "Selyanskoye for kids" dairy producers. The fatty acid composition of the drinking cow’s milk distributed across trading networks in Kiev was found to be heterogeneous, by differing in the content of both long-chain saturated fatty acids and unsaturated fatty acids. If considering the lipid composition of drinking milk and disregarding the impact of pathological factors (such milk is not used), as well as product counterfeiting, the following should be mentioned: breed and physiological characteristics of the lactating animals; the diet composition; technologies for keeping dairy cows (grazing on pastures, exercise, transportation, etc.); technologies for obtaining drinking milk. Some researchers believe that the behaviour, exercise, and grazing intensity and duration of lactating animals can affect the composition and quality of the milk obtained [1, 2].
