Abstract
A process for preparing a natural flavor concentrate comprising flavor chemicals derived from a fruit or vegetable juice distillate, wherein the distillate is subjected to reverse osmosis, is disclosed; the distillate is characterized by being substantially free of saccharide and the reverse osmosis is continued until a retentate is obtained that can phase separate, and the retentate is phase separated into an aqueous phase and a substantially anhydrous organic phase which contains a high proportion of the flavor chemicals, and the organic phase is recovered. The natural concentrate derived from the process, which is substantially free of saccharide, is also disclosed.

A process for preparation of a natural flavour concentrate comprising flavour chemicals derived from a fruit or vegetable juice distillate comprising subjecting the distillate to reverse osmosis characterised in that the distillate is substantially free of saccharide and reverse osmosis is continued until a retentate is obtained that can phase separate, the rententate is phase separated into an aqueous phase and a substantially anhydrous organic phase which contains a high proportion of the flavour chemicals, and the organic phase is recovered.
A natural concentrate derived by concentration of a fruit or vegetable juice distillate, which is substantially free of saccharide and upon dilution is substantially the flavour of the original juice, the concentrate comprising below 25% by weight water, 10-30% C.sub.1-4 alcohols and aldehydes and 50-80% organic chemicals having at least 5 carbon atoms.
