| Abstract: | Extraction effect of soybean oligosacchride in various solvents was compared using cooled defatted soybean meals as raw material.The better conditions were:1%Na2CO3，extraction temperature 55℃ and extraction time 2 hours.After being dissolved by alkali then being precipitated by acid,remaining protein was removed by Ultrafiltration(UF) and through orthogonal tests.The optimum condition was:25℃,pH6.3,and membrane prssure 20 psi.The product was obtained by concentrated under vacuum after desalting by ion exchange. |
