It has been observed that the aqueous extract of red kidney beans was extremely difficult to filter. Attempts have been made to eliminate the difficulty in filtration of the bean extract through the use of some commercial good-grade enzyme preparations. Among the enzymes used, only Cellulase 36 and Rhozyme HP-150 were found satisfactory for this purpose. The improvement in filterability of the bean extract appeared to be a result of enzymatic breakdown of bean polysaccharides and oligosaccharides into simple, soluble sugar units. The enzymes were also capable of improving greatly the extractability of nitrogenous constituents from red kidney beans.
