摘要：The purpose of experimental research was to determine the number of viable cells L. acidophilus of the strain La-5 and Flora Danica when storing cultured butter. For this purpose, we employed different temperature modes of the fermentation of cream, as well as various technologies. The original concentration of cultures in cream is 1•106 cfu/cm3; with a combination of cultures – the ratio of 1:1 at original concentration in cream of 1•106 and 1•106 cfu/cm3, respectively). We prepared 4 groups of butter:– group I (samples BW (Butter Winter)1, BW2, BW3 and BS (Butter Summer)1, BS2, BS3 at souring the cream by FD, FD + La-5, La-5, respectively, in winter and summer). Cream fermentation was conducted at temperature (30±1) ºC;– group II (BW4, BW5, BW6, BS5, BS6, BS7 at souring by FD, FD+La-5; La-5) – fermentation (37±1) ºC;– group III (З7, З8, З9 at souring by FD, FD+La-5, La-5, respectively) – (8±1) ºC→(20±1) ºC→(12±1) ºC – winter stepwise cultured butter production mode similar to the Alnarp mode. (BS7, BS8, BS9) – (20±1) ºC→(6±1) ºC→(10±1) ºC – summer stepwise mode similar to the Danish one;– group IV (BW10, BW11, BW12, BS10, BS11, BS12 at souring by FD, FD+La-5, La-5, respectively) – introduction of souring cultures to a butter grain. The original concentration of cells at inoculation – 1•108 cfu/cm3.The largest number of viable cells of La-5 was registered for the sample in which we used FD+La-5 and the fermentation of cream at temperature (30±1) ºC. Duration of storing the cultured butter with the probiotic properties is 35 days at temperature 0…–5.
