FOAMING COFFEE COMPOSITION Russian patent published in 2014 - IPC A23F5/24 A23F5/32 A23F5/38 

FIELD: food industry.

SUBSTANCE: inventions group relates to food industry. The instant coffee foaming composition contains particles having pour density equal to 0.16 - 0.45 g/cm³. The particles include a continuous phase containing an instant coffee matrix and an interrupted phase containing a foaming component particles; the interrupted phase is captured inside the instant coffee matrix; the foaming component contains at least one of the ingredients in the form of particles having multiple inner cavities containing trapped gas under a pressure higher than atmospheric one, an ingredient in the form of particles having multiple inner cavities containing condensed liquid or supercritical liquid and a gas-containing clathrate. The closed pores volume accounts for at least 0.10 cm³/g. The method involves mixing of the said foaming components particles with a water coffee extract to produce a coffee mixture. The coffee mixture is frozen before the foaming components particles are dissolved, the frozen coffee mixture is granulated to prepare a coffee composition subjected to sublimation drying by way of water removal by way of sublimation. The composition production method version involves the said foaming components particles mixing with instant coffee particles. The mixture of instant coffee particles and foaming components particles is agglomerated at a temperature exceeding the foaming component glass transition temperature to form agglomerated particles including a continuous phase containing an instant coffee matrix and an interrupted phase containing the foaming component particles; the interrupted phase is captured inside the instant coffee matrix; the agglomerated particles are dried. The coffee beverage is prepared by way of addition of hot water to the produced composition.

EFFECT: inventions group is aimed at production of a composition with high foamy efficiency; at the same time, however, the composition is similar to traditional sublimated instant coffee in terms of the composition colour and pour density.
