Abstract

The main aim of this review is to summarize the knowledge of size reduction theory in grinding, working and importance of cryogenic grinding over convention method. Conventional grinding methods can be used to grind the species, but the problem of increase in the temperatures during grinding may lose the volatile oil compounds, natural flavour and aroma. But, in cryogenic grinding those quality attributes could be retained by using cryogenic liquids which maintains low temperatures during grinding.
