| Abstract: | ![]()
Calcium soaps of high oleic sunflower oil (HOS-Ca) were prepared, using alkaline hydrolysis and calcium precipitation, and freeze-dried. Cows’ diets were prepared to provide 0, 0.85 kg or 1.7 kg HOS-Ca/day. Fatty acids and cholesterol were determined by gas chromatography. Sensory evaluations of milk from cows fed 0 and 1.7 kg HOS-Ca/day were conducted using triangle tests. The 18:lco9 concentration in milk from cows fed the 1.7 kg HOS-Ca diet increased from 22.9 to 35.2% compared to the control (p<0.05). Concentration of total medium-chain saturates (C12-C16) decreased from 40.7 to 31.4% (p<0.05). Feeding HOS-Ca resulted in increases of monoene fatty acids and lower medium-chain saturated fatty acids but no change in milk flavor. |
