Fatty acid composition of mayonnaise based on sunflower and linen oil
Abstract
The study demonstrates the peculiarities of the fatty acid composition of oils and samples of mayonnaise prepared on the basis of these oils. The fatty acid profile of sunflower and linseed oil samples and control and experimental mayonnaise samples was investigated by gas-liquid chromatography. It was established that the ratio between PUFAs of the ω-9/ω-6/ω-3 families in the investigated sunflower oil samples is 177 : 553 : 1. This is due to the high content of linoleic and oleic acids. In the studied samples of linseed oil, the content of α-linolenic acid is 52 %, and the content of oleic (ω-9) and linoleic (ω-6) acids is 22.3 and 16.2%, respectively. Therefore, the ratio between ω-9/ω-6/ω-3 PUFAs in the studied samples of linseed oil is 1.4 : 1 : 3.2. It was established that mayonnaise (Control – K), which was prepared on refined sunflower oil with its content of 71.78 %, was characterized by a high content of PUFAs of the ω-6 family and a low content of PUFAs of the ω-3 family. The ratio of PUFAs of the ω-3, ω-6 and ω-9 families in this sample of mayonnaise is 1:13:7.3. In the sample of mayonnaise (Experiment – E) with a content of 35.03 % of sunflower and linseed oils, the total content of PUFAs of the ω-3 family is 24.0 %, which is 20.3 % more than in K. Such an increase in the content of PUFAs of the ω-3 family is due to the high content of α-linolenic acid – 23.1 %. The total content of PUFAs of the ω-6 family in mayonnaise E is 33.6 %, which is 16.04 % less than in sample K. The content of PUFAs of the ω-9 family in sample E is not significantly different from that in sample L. The ratio between the content PUFA of the ω-3/ω-6/ω-9 families in sample E is 1:1.4:1.1. Sample E of mayonnaise has a lower total content of saturated fatty acids, which was 14.88 %, compared to 18.26 % in sample K. Thus, replacing 50 % of sunflower oil with linseed oil in the manufacturing process of mayonnaise sample E gives a number of positive advantages compared to sample K, which contains only sunflower oil in its composition. Thus, the total content of PUFAs of the ω-6 family decreases, the total content of PUFAs of the ω-3 family increases, the ratio between the content of PUFAs of the ω-3 / ω-6 / ω-9 families is balanced, the content of saturated fatty acids decreases and, accordingly, the content of unsaturated fatty acids increases. The results of the analysis of the fatty acid composition of mayonnaise sample E allow recommending this emulsion oil-fat product as a functional product due to the high content of PUFAs of the ω-3 family and the balanced ratio between the content of PUFAs of the ω-3 / ω-6 / ω-9 families.
