Abstract

The objective of the research was to study effect of soaking temperature and soaking time against the physical characteristics of seed and the yield of soybean milk . The research was conducted at laboratory of Agricultural Product Processing Chemistry, Department of Agricultural, Faculty of Agriculture, Sriwijaya University, from February to June 2012. The research was used descriptions through observation, tabulation and graphical presentation with 2 factor treatments that is the soaking time(T) and soaking temperature (P). Each treatment factor consisted of three treatment factors. Observed parameters were weight increment of soybean, volume increment of soybean and texture of soy bean. The result of this research showed that soaking temperature and soaking time significant for yield percentage and rate of centrifugal separation. Soaking for 12 hours significantly improved the percentage yield, which in this study up to 76.90%. Soaking with the temperature 54 ° C significantly increased the percentage of yield of up to 76.82%. The highest rate of separation is 11.08..
