Abstract From the Canadian patent

Processes for dehusking psyllium seeds to obtain high yields of high purity psyllium seed husk. These processes comprise milling intact psyllium seeds in a mill which causes the husk to be fragmented by collision under conditions whereby the husk is fractured and separated from the non-husk portion of the psyllium seed without substantial breakage and size reduction of the non-husk portion. Preferred milling utilizes impact speeds within the range of from about 5m/sec to about 40m/sec.
