Abstract: Lyophilized synbiotic product from cow milk from Bulgarian Rhodopes cattle breed was developеd. As starter culture was used probiotic complex of selected strains of lactic acid bacteria: Lactobacillus bulgaricus 1381, Streptococcus thermophilus 1374, Lactobacillus acidophilus 1379, included in chitosan gel. The composition of the lyophilized product was enriched with natural ingredients – cereals, sesame, linseed oil, mango, stevia. The cow milk and the produced freeze-dried product were examined by physiochemical parameters, fatty acid composition and content of macro- and microelements. The results indicate that the synbiotic product is rich in proteins, sugars, polyunsaturated fatty acids, including the essential fatty acids (ω–3 and ω–6), vitamin C, mineral substances (Mg, Na, P, Mn, Fe, Cu , Zn), some of which are imported by natural additives. Enriched on this basis, fermented cow milk is characterized with improved qualitative composition, which defines it as a functional product with an extended physiological and health benefits.
