  • Extraction of gossypol from cottonseed
    Patent number: 5112637
    Abstract: The present invention is drawn to a process for extraction of gossypol for cottonseed using a solvent solution which includes: (a) a water miscible organic solvent; (b) water; and (c) an acid which is strong enough to prevent binding of gossypol to cottonseed protein but which is not so strong as to hydrolyze a substantial portion of the cottonseed protein. The present invention also includes cotton seed meals of reduced gossypol content (and optionally reduced aflatoxin and/or fat content) produced by the aforementioned extraction.

  • Inlet system for direct gas chromatographic and combined gas chromatographic/mass spectrometric analysis of food volatiles
    Patent number: 4245494
    Abstract: An apparatus for analyzing volatile components from raw or processed food products using either direct gas chromatography or combined direct gas chromatography and mass spectrometry is disclosed. An inlet assembly containing a sample is appropriately affixed to a means of supplying helium carrier gas. Volatiles are driven off the sample and fed to a condenser assembly where the moisture is removed. The resultant moisture free volatiles are fed to a gas chromatograph or combined direct gas chromatograph and mass spectrograph for analysis.
