Coffee and cowpea beans were kept under refrigeration. For the grinding of samples the first aliquot was discarded. A two-step program was used for cryogenic grinding. Samples were frozen for 5 min and ground for 2 min. Three grinding cycles with a cooling step of 1 min between cycles were applied.

A frozen or chilled product is more brittle, fragile which makes grinding easier. The freezing process prevents the loss of aroma and taste, making the final product more valuable. This cryogenic freezing technique is used to grind herbs, spices (eg. nutmeg, mustard, peper, allspice), seeds (eg. coffee), dried fruits or to reduce powder grade.
