Abstract: This paper estimated the stability of peanut milk through mechanism study from three different ways before and after sterilization. Through the rate of centrifugal sedimentation and the rate of fatty float, several macroscopical ways were used to judge the stability of peanut milk emulsion. Through microscopical photographs to estimate the stability of peanut milk from microcosmic way. The pH, viscosity and conductibility were used to help judge the stability of peanut milk emulsion.

Key words: CMC, peanut milk, sterilization, stability
