Abstract

Extraction of oligosaccharides from cottonseed meal was carried out by water. Macromolecular impurities in extracts,such as protein,pectin,pigment,were removed by the ultrafiltration. Based on the effect of MWCO( molecular weight cut offs),the optimum parameters were 5 kDa MWCO,20 psi and 35 ℃. The transmittance of total sugar,raffinose,stachyose and sucrose was 88. 7%,86. 3%,87. 2% and 98. 1%,respectively. The protein removal rate was 75%. The conclusion is that ultrafiltration is efficient in purification of oligosaccharides from cotton seed meal water extracts.

Key words： cottonseed oligosaccharides; ultrafiltration; purification
