IVANOVA, S., I. NACHEVA, D. MITEVA, K. DIMOV and Tsv. TSVETKOV, 2010. Physicochemical composition, atherogenic index and prevantive lipid score of buffalo yoghurt after technological treatment and preservation. Bulg. J. Agric. Sci., 16: 407-411
The physicochemical composition and the content of fatty acids in the mild fat of buffalo yoghurt after lyophilization and treatment with gamma rays with doses 2 and 4 kGó has been studied. A comparatively constant physical-chemical composition of the buffalo yoghurt after treatment by the two technological methods and preservation for six months has been established. The indices atherogenic index /AI/ and lipid preventive score /LPS/ have been used for determining of the quality of the buffalo yoghurt. The studied buffalo milk fat after lyophilization and gamma irradiation has a relatively low atherogenic index which is a nutritionally valuable factor in relation to the risk of cardio vascular diseases. The buffalo yoghurt has a high lipid preventive score which is an index of a relatively high content of saturated fatty acids (SFA) and low concentration of unsaturated fatty acids (MUFA, PUFA).
