Abstract: Aqueous extracts of roasted coffee are stripped of aroma, concentrated and thereafter decaffeinated by means of contact with a decaffeinating fluid such as liquid or supercritical carbon dioxide. Aroma loss is minimized by using water to remove caffeine and aroma from the CO.sub.2 stream, recovering aromatics from this caffeine-containing aqueous stream and adding-back these aromatics to the decaffeinated extract. Preferably equipment cost is minimized by use of a single pressure vessel to transfer the caffeine from the extract stream to the CO.sub.2 and from the CO.sub.2 to the water stream.
Abstract translation: 将咖啡的水提取物除去香气，浓缩，然后通过与脱咖啡因流体如液体或超临界二氧化碳的接触而脱咖啡因。 通过使用水从CO 2流中除去咖啡因和香气，从含咖啡因的含水流中回收芳烃并将这些芳族化合物加入到脱咖啡因的提取物中，使香气损失最小化。 优选地，通过使用单个压力容器将咖啡因从提取物流转移到CO 2和从CO 2到水流来最小化设备成本。

Abstract: An adsorbate is removed from an adsorbent by contacting the adsorbent with a near critical liquid which is a solvent for the adsorbate. The near critical liquid containing the dissolved adsorbate is then subjected to at least partial vaporization to form a vapor in which the adsorbate is substantially less soluble thereby making it possible to remove the adsorbate from the near critical liquid. The vapor is then condensed to restore it to the near critical liquid state wherein it is a solvent for the adsorbate so that it may be reused. The process is particularly suitable for adsorbent regeneration in the treating of waste-waters.
Abstract translation: 通过使吸附剂与作为被吸附物质的溶剂的临界液体接触使吸附剂从吸附剂中除去。 然后将含有溶解的被吸附物质的近临界液体进行至少部分蒸发以形成蒸汽，其中被吸附物的溶解度基本上较低，从而使得可以从近临界液体除去被吸附物质。 然后将蒸气冷凝以将其还原成近临界液体状态，其中它是用于被吸附物的溶剂，使得其可以重复使用。 该方法特别适用于废水处理中的吸附剂再生。

Abstract: A method for pressing a liquid extract out of a material to be pressed. The material to be pressed is supplied to a screw press and is transported along a pressing path in the screw press, and a pressing pressure is applied to the material to be pressed. The screw press is supplied with an extraction agent (e.g., carbon dioxide) which is discharged from the material to be pressed together with the extract. The carbon dioxide is supplied to the screw press in the form of dry ice pellets. The dry ice is mixed with and transported together with the material to be pressed through the screw press along the pressing path. The dry ice is converted into liquid or supercritical carbon dioxide, which dissolves in the extract and reduces the viscosity thereof and which effectively cools the material to be pressed in the screw press.

Abstract: An extract of a plant chosen from Tasmannia lanceolata, Drimys winteri, Spilanthes acmella and Polygonum hydropiper is obtained from ground and dried leaves of said plant by supercritical CO2 extraction at a pressure of between 120 and 350 bar and at a temperature from 35 to 60° C. and contains polygodial. A process for obtaining such an extract is disclosed along with compositions comprising, in a physiologically acceptable medium, an effective amount of the extract to promotes wound healing and decrease inflammation in skin disorders.
