  • Patent number: 5534280
    Abstract: A process for treating a solid food product having water soluble and water insoluble volatiles soluble in alcohol and ether. The process includes cutting the product into pieces, placing the product pieces in a volume of water containing an anti-oxidant, and drawing a vacuum on the product pieces in the water to pull air out of the cells of the product pieces. The vacuum is released to cause water, and the anti-oxidant to enter the cells of the product pieces. The product pieces are then heated to dry the pieces and to drive off a mixture of water vapor or steam and the water soluble and water insoluble volatiles. The mixture is directed through an adsorbent to remove the water soluble and water insoluble volatiles from the mixture by an adsorption. Steam is passed through the adsorbent to remove the water soluble volatiles from the adsorbent. Ethyl alcohol is passed through the adsorbent to remove the alcohol soluble, water insoluble volatiles from the adsorbent.
