RAPESEED WET GUM AS A DIRECT SOURCE OF HIGH-QUALITY LECITHIN

The acetone deoiling and dehydration processes of rapeseed wet gum wer e investigated for deoiled lecithin preparation. The yield, the deoili ng efficiency and the quality of lecithins obtained from wet gum were compared with those prepared from the commercial raw lecithin. Beside, the extraction parameters were also discussed. Basing on the performe d investigations it could be summarized that the deoiling and dehydrat ion processes are more effective when the lecithin wet gum is used. Th e quality of deoiled lecithin prepared from wet gum is also better tha n that obtained from other commercial raw materials.
