摘要： This invention is directed to a process for the production of extracts from spices in two stages by extraction with a non-toxic gas as solvent, the improvement which comprises in a first stage extracting from the spices essential oils functioning as aroma components by contacting the spices with liquid solvent, at a pressure in the supercritical range and a temperature in the subcritical range, separating the solvent from the spice, evaporating the solvent and separating essential oils, and in a second stage extracting from the spices the portions acting as flavor carriers by contacting the spices from the first stage with gaseous solvent, at a pressure and a temperature both in the supercritical range, separating the gaseous solvent from the spice, reducing the pressure and temperature, and separating the flavor carriers from the gaseous solvent.

摘要： This invention relates to a process for concentrating aqueous solutions having temperature-sensitive components. More particularly, this invention relates to an improved process for concentrating aqueous solutions having temperature-sensitive components which comprises the steps of:(a) subjecting the aqueous solution to an ultrafiltration procedure to provide a permeate solution and a residual solution; and(b) subjecting the permeate solution from step (a) to freezing and removing ice crystals formed thereby.
