Read MoreCryogenic grinding is a method of powdering spices at sub-zero temperatures ranging from 0 to minus 70°F. The spices are frozen with liquid nitrogen as they are being powdered. This process does not damage or alter the chemical composition of the spices in any way. Normal grinding processes which do not use a cooling system can reach up to 200°F.
Read MoreCryogenic grinding not only retains the volatiles in both the genotypes but enhanced the recovery also. Non cryogenic or normal grinding at ambient temperature causes 18-19 % loss of volatile oil in both the genotypes. A significant increase (28.28%) in oleoresin percentage was observed when seeds of RZ 209 were ground using cryogenic grinding.
