In one type, a membrane contactor facilitates contact between bittering agents present in a citrus juice feed and a hydrophobic bittering agents extraction fluid; a second membrane contactor may be used to extract bittering agents from the hydrophobic extraction fluid by use of a basic stripping fluid on the permeate side. In a second type, an immobilized liquid membrane containing hydrophobic extraction fluid supported within the pores of a microporous hydrophobic polymeric membrane is used to facilitate transport of bittering agents across the membrane.Field of SearchMEANS TO TREAT FOODBy applying fluid Particular liquid Brine Water By isolating a fluid constituent By separating liquids having distinct characteristics With removal of solid foreign matter BEVERAGE Treatment of liquid with nongaseous material other than water per se Fruit and vegetable juice Fruit and vegetable juice INVOLVING ION EXCHANGE, SEQUESTERING OR CHELATING MATERIAL Solid polymer derived from ethylenically unsaturated reactant only Treated with sulfur-containing material | |
