1. A method for processing of guar endosperm to isolate the galactomannan of D-galactose and mannose component (guaran) therefrom, comprising:
- providing guar endosperm halves;
bringing the halves into contact with liquid ammonia at an initial pressure, higher than atmospheric pressure, and at a temperature of at least 25°
C., the amount of liquid ammonia being sufficient at least for wetting the surface of the guar endosperm halves; and
increasing the volume available to the system of guar endosperm halves and liquid ammonia explosively by lowering the pressure by at least about 0.5 Mpa (5 bar) to tear open the sheaths of the guar endosperm halves to isolate the guaran.

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.
