Extremely high pressure limits to enlarge the effective volume of the device. At the same time, higher equipment manufacturing and running costs restrict the technique and its application in the production of effective components of natural products. 亚临界萃取脂溶物质专利技术是国家科委“火炬计划”、国家计委“科技先导计划”和国家经贸委“科技示范计划”项目。目前已广泛应用于特种食物油、植物蛋白、精细化工、天然色素、医药、食品等行业，先后在国内建成了四十多家项目。亚临界萃取溶剂的主要成分为液化丁烷或丙烷。该溶剂中组分的沸点大多在零度以下，其中丁烷沸点-0.5℃， 丙烷的沸点为-42.1℃，常温常压下为气体，加压后为液态。该工艺的基本原理：在常温和一定压力下（0.3兆帕—1.0兆帕）,用该溶剂逆流浸出油料料胚，然后使混合油（或浸膏）和粕中的溶剂减压汽化，汽化后的溶剂气体再经过压缩机压缩冷凝液化后循环使用。 Sub-critical extraction of lipid-soluble
