Abstract
There are disclosed two types of apparatus using membrane extractions of citrus juice bittering agents, both using extraction fluids. 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.
