  • Removal of xanthine stimulants from cocoa
    Patent number: 4861607
    Abstract: Xanthine stimulants are extracted from a cocoa material containing a fat by adding water to the cocoa material for swelling it with at least 0.1 part by weight of water per part by weight of cocoa. The swollen material is then contacted with a food-acceptable solvent gas which is supercritical in respect to temperature and pressure, after which the solvent gas containing the stimulants is separated from the swollen cocoa material which thereupon has a reduced content of stimulants.
    Type: Grant

  • Recovery of xanthine stimulants from aqueous media
    Patent number: 4407834
    Abstract: A process for the recovery of xanthine stimulants from an aqueous solution containing xanthine stimulants extracted from cocoa material, which comprises contacting the solution with a substantially neutral adsorbent and separating the adsorbent, with the xanthine stimulants adsorbed thereon, from the aqueous solution having a reduced content of xanthine stimulants.

  • Spice extract
    Patent number: 4158708
    Abstract: A process for the production of an aromatic spice extract, which comprises(a) grinding a spice and collecting an aromatic fraction A, consisting of the gases given off during grinding,(b) treating the spice with an apolar organic solvent so as to obtain an aromatic fraction B contained in this apolar solvent, and(c) treating the spice with at least one polar solvent so as to obtain an aromatic fraction C contained in this polar solvent,The combination of the aromatic fractions A, B and C constituting the aromatic spice extract.The polar and apolar organic solvents may be used in mixture, especially in azeotropic mixture.
