A METHOD OF EXTRACTING LECTIN FROM THE COMMON BEAN AS WELL AS A LECTIN PREPARATION

摘要

A method of the industrial production of a lectin preparation from bean seeds, in which a lectin fraction is extracted from bean seeds in an extraction system containing acetic acid, an antioxidant, as well as a highly volatile organic acid or its salt, at a lowered temperature and substantially without mixing, and subsequently, after concentrating, preferentially on membranes, the resulting PHA fraction is supplemented with a poorly volatile preservative and it is dried by spray- drying resulting in a lectin preparation with a lectin activity of no less than 128 HU/100 mg of preparation, with a lowered level of ballasting substances.
