| Abstract: | In this experiment,colony count in fresh soybean milk was determined by dilution method of plate counting.Three types of colonies,one kind of white bacterial colony,one kind of black and one kind of white actinomycete,appeared in peptone beef medium.The colony count was 8.3×108 CFU/mL.Colony count in fresh soybean milk was determined after being heated to begin boiling.It was 610 CFU/mL.And it was zero when the fresh soybean milk was heated to boil and kept at least 2 minute.So the fresh soybean milk needs to be heated before being drinked. |
