Evaluation of the fatty acid profile of symbiotic chevrotin cheese

Abstract

Foods with probiotic or prebiotic bacteria are included in the category of foods containing bioactive compounds that have aroused interest because of the beneficial effect on health. The objective of this study was to evaluate the effect of chevrotin cheeses from caprine, bovine and mixed milk with the use of a prebiotic (inulin), associated to the use of a probiotic, Bifidobacterium lactis. Nine cheeses were allocated in a completely randomized design with factorial (3x3) in three types of milk and three levels of inulin (0.0%, 2,5% and 5,0%). Fatty acid analysis was performed. According to the results, the percentage of saturated fatty acids (AGS) increased linearly (p < 0.01) the concentration of the monounsaturated acids (MUFA) and the concentration of the polyunsaturated acids (PUFA). Thirty fatty acids were identified, including 17 saturated, 9 monounsaturated and 4 polyunsaturated. The composition of fatty acids in the different types of cheeses presented a higher content of monounsaturated and polyunsaturated fatty acids in goat and mixed cheeses and higher content of saturated fatty acids in cheeses with bovine milk.
