Abstract: A shelf-stable liquid base composition useful for preparing acidified milk based beverages, e.g. by dilution with water in a beverage dispensing machine, comprises: from about 2 to about 10 weight % of denatured milk proteins expressed as solid-not-fat (SNF) milk components; from about 15 to about 80 weight %, expressed as sugar equivalents, of a carbohydrate based or non carbohydrate based sweetener; from about 0.35 to about 1.50 weight % of a carbohydrate based stabilizer; and an acidifying agent present in amounts necessary for achieving a pH of about 3.0 to about 3.8 of the said base composition. Methods for preparing such a base composition and also acidified milk based beverages prepared by means of such a base composition are disclosed.

Abstract: Methods and systems to deliver foamed beverages from liquid concentrate(s) through a dispenser machine are presented. In an embodiment, the method and system for improving foam quality by generating foam with the desired texture, stability and bubble size distribution comprises use of a low viscous liquid(s) to generate a primary foam, which is then stabilized by mixing it with liquid(s) of higher viscosity. To create high quality foam, different dosing protocols including two approaches such as delivery of foaming liquid concentrates at different concentration, or getting different concentration by varying water dosing times and/or flow rates were used. Positive results were found for the dispensing systems using milk and other liquid concentrates at specific dispensing conditions (flow rates and times).
