Cryogenic technique in value addition of spices

Traditional grinding techniques can be used to grind the spices but because of the increase in the temperature during grinding process natural flavour and aroma will be lost. Cryogenics is the study of low temperature and behaviour of material under low temperature conditions. Precooling of the raw spice and the continuous low temperature maintained within the cryogenic system reduces the loss of volatile oil and moisture. Cryogenic grinding
