Abstract: Rice and starch syrup were isolated from long rice or broken rice by amylase. The results showed that the contentof rice protein was 59.82 percent by adding 5u/g amylase enzyme, pH6.3～6.5. The content of ash could be decreased to 1.52percent by rowing isolation. The content of fat could be decreased to 2.72 percent by cellulase and lipase. The content of proteinin the rice concentrate protein was 70 percent, recovery was 73.96 percent.

Key words: rice, concentrate protein, enzyme, extract, technology
