14. © Food - a fact of life 2009 Cryogens The extremely low temperature are produced by using substances called " cryogens" such as liquid nitrogen and liquid helium. All cryogenic liquids are gases at normal temperatures and pressures. So, these gases must be cooled below room temperature to liquefy them. They have boiling points below -150°C.

Our results suggest that cryogenic grinding enhances protein release rate to almost 1000 fold as compared to ambient condition grinding process. Although DNA release rate was found to be relatively low as compared to that of protein, the release was very high, approximately 1 mg DNA per 100 mg of yeast.
