Abstract: A method of making a clear beverage concentrate, which comprises a nanoemulsion of a liquid flavour oil in an aqueous phase, comprising the emulsification of the flavour oil into water in the presence of an emulsifier, which emulsifier consists of at least 5% by weight quillaja saponins, optionally containing at least one other emulsifier, characterised in that, prior to emulsification, the pH of the aqueous phase is adjusted to 4.0 maximum. The method allows the preparation of beverages that not only are crystal-clear, but which also have substantially more of the full flavour of the original flavour oil.

Abstract: A tea-flavoured beverage concentrate, comprising a beverage concentrate base in which tea flavour is provided by the incorporation of tea distillate. Dilution of this composition results in a tea-flavoured beverage that suffers from less of the cloudiness, precipitation or sedimentation that has previously been encountered in preparing tea-flavoured concentrates.
