Cryogenic grinding of black pepper - ScienceDirect

2008-3-1  During cryogenic grinding, the vapourisation of oils is minimum as most of the oil compounds are retained within the powder itself because of low temperatures, and the oils are present mostly as solid. The dust formation is also marginal. These specific advantages of cryogenic grinding thus show the practical usefulness of this .3.1.3.
