FROZEN AERATED FOOD PRODUCT CONTAINING SURFACE-ACTIVE FIBRES Russian patent published in 2012 - IPC A23L1/00 A23G9/04 A23L1/534 

FIELD: food industry.

SUBSTANCE: inventions group relates to food industry, in particular, to ice-cream, fruit ice, frozen cream etc. The product has overrun equal to at least 30%, contains surface-active fibres of non-waxy material (in an amount of 0.001 - 10 wt %) modified with ethylcellulose and/or hydroxypropyl cellulose; the fibres length to diameter ratio value is equal to 10 - 1000. The product preparation method involves stages of preparation of a water dispersion containing surface-active particles, addition of fibres (in the form of dry powder or water dispersion) to the said dispersion, introduction of air and homogenisation of the produced mixture whereby the fibres join with the surface-active particles in situ on the boundary surface between the air and water phases as a consequence of interaction attraction between the surface-active particles and the fibres for formation of stable foam and freezing of the produced foam. A dry or liquid premix of components for the product production.

EFFECT: inventions group allows to produce a product with good stability of the air phase, storage stability, good melting properties; the product may be transported unfrozen without loss of shape.
