Abstract

A method for processing guar endosperm in which guar splits are brought into contact with an amount of liquid ammonia at least sufficient to wet the guar splits at a pressure higher than atmospheric pressure and at a temperature of at least 25° C. The remaining available guar split/liquid ammonia system volume is increased in an explosion like manner by reducing the pressure by at least about 5 bars resulting in the sheaths of the guar splits being torn open to result in a product that can be processed more easily, such as by grinding.
