Cryogenic grinding not only retains the volatiles in both the genotypes but enhanced the recovery also. Non cryogenic or normal grinding at ambient temperature causes 1819 % loss of volatile oil in both the genotypes. A significant increase (%) in oleoresin percentage was observed when seeds of RZ 209 were ground using cryogenic grinding.
Cryogenic grinding of plant and animal tissue is a technique used by microbiologists. Samples that require extraction of nucleic acids must be kept at −80 °C or lower during the entire extraction process. For samples that are soft or flexible at room temperature, cryogenic grinding may be the only viable technique for processing samples.
