Summary: The aim of the study was to determine the effects of coconut fat content on selected parameters of a fermented coconut “milk” beverage stored for 28 days at 6 °C. Two variants of coconut beverages were prepared, namely, the low-fat (containing 20 g·kg-1 fat) and the full-fat (containing 150 g·kg-1 fat), obtained by addition of raw „organic” coconut oil. Raw “organic” coconut oil is rich in saturated fatty acids, mainly lauric and myristic acids (51.3 % and 15.6 % of total fatty acids, respectively). The sterol profile of the raw coconut oil indicated the presence of beta-sitosterol (274.2 mg·kg-1), delta-5-avenasterol (159.8 mg·kg-1), stigmasterol (89.9 mg·kg-1) and campesterol (40.5 mg·kg-1). The populations of lactic acid bacteria (> 6 log CFU·ml-1), bifidobacteria (> 6 log CFU·ml-1) and pH (in range of 4.17–4.50) of the fermented coconut beverages did not depend on the fat content. The two variants of coconut beverages differed significantly in hardness, adhesiveness and syneresis, but did not differ in consistency visually.
