abstract:
In the study an attempt was made at removing saponin from the surface of quinoa grains (Chenopodium quinoa Willd.) by means of mechanical abrasion. The influence of abrasion intensity and of the time of the operation was examined with relation to the content of saponin on the surface of grains. In the research two kinds of abrasion drums were applied, and three kinds of abrasive materials. The content of saponin was determined with the foam test. It was demonstrated that the that kind abrasive used and the duration of the operation had a considerable effect on the level of saponin content on the surface of the grain. A considerable reduction in the level of saponin could be achieved with proper selection of those parameters.
