Functional Odd- and Branched-Chain Fatty Acid in Sheep and Goat Milk and Cheeses

The inverse association between the groups of odd-chain (OCFA) and branched-chain (BCFA) development diseases in humans have generated interest scientific community. In experiment 1, extent passage odd- fatty acids (OBCFA) from milk fat to fresh cheese was studied sheep goats. Milk collected two processing plants west Sardinia (Italy) sampled every 2 weeks during spring (March, April May). addition, a survey carried out evaluate seasonal variation OBCFA concentrations goats’ cheeses all lactation period January June. Furthermore, assess main differences among goat cheese, principal component analysis (PCA) applied (FA) profile. Concentrations both species were strongly related FA content unprocessed raw milk. average contents 4.12 4.13 mg/100 mg respectively, 3.12 3.17 respectively. concentration did no differed any species. significantly higher than dairy products. composition markedly affected by sampling species: odd branched increased March changes products likely connected variations quality diet. PCA confirmed nutritional for beneficial FA, including compared one, importance definition
