title: Insoluble condensed tannins of canola/rapeseed.
abstract: The contents of soluble, SDS-extractable, and insoluble condensed tannins were determined in canola/rapeseed hulls from several varieties by utilizing the proanthocyanidin assay. The total amount of tannins in rapeseed/canola hulls ranged from 1913 to 6213 mg per 100 g of oil-free hulls. Insoluble tannins predominated in canola/rapeseed hulls and comprised from 70 to 95.8% of total tannins present. The amounts of SDS-extractable tannins were comparable to those of soluble tannins but constituted only 4.7-14. 1% of insoluble tannins present.
