Fatty acid composition in beebread
V. ČEKSTERYTĖ, J. RAČYS, V. KAŠKONIENĖ, P. R. VENSKUTONIS
Pollen and fatty acid composition were studied in the beebread collected in spring and summer. Willow pollen in spring beebread comprised 45.1 ± 3.0%, while rape pollen in summer beebread constituted 78.7 ± 4.5%. Twenty-two fatty acids were identified in beebread, including five ω-3, four ω-6 and three ω-9 polyunsaturated fatty acids. The ratio of ω-6 and ω-3 fatty acids was 1 : 1 in beebread samples where rape pollen constituted 45.1 ± 3.0% and 61.7 ± 4.0%, while this ratio was 2 : 1 in the beebread with a higher content of rape pollen, 78.7 ± 4.5%.
