摘要：
FIELD: food industry.SUBSTANCE: group of inventions relates to coffee industry. Coffee milling is performed by introducing particles of a roasted coffee precursor and introducing particles of soluble coffee into milling chamber, jetting a gas into milling chamber to increase, by means of glass flow, speed of coffee particles in chamber. Product is obtained, containing 10 % to 70 % of dry weight of roasted coffee precursor and 30 % to 90 % of dry weight of soluble coffee, by milling, through injecting gas into milling chamber and increasing speed of particles of roasted coffee precursor and soluble coffee in milling chamber, particles of roasted coffee precursor using self-collision and through collision of soluble coffee particles with particles of roasted coffee precursor inside milling chamber. Particles of roasted coffee precursor at step of introduction of particles are characterised by temperature from 5 to 30 °C. Ground and blended coffee product is characterised by dry Helos particle size distribution D90 less or equal to 40 mcm. Use of ground and blended coffee product to include in at least one container suitable for use in combination with machine for beverage preparation, for example, a flexible capsule made at least partially from filtering material, or rigid, semirigid or flexible cartridge, made essentially of air- and water-impermeable material. Method for beverage preparation includes a step of mixing milled and blended coffee product with water-containing liquid, preferably with hot water.EFFECT: group of inventions enables to reduce size of particles of roasted coffee without negative effect, which is manifested by early extraction of coffee oils of roasted coffee precursor, absorption by soluble coffee of a certain quantity of coffee oils, introduction of roasted milled coffee with small-size particles into a dried frozen soluble coffee product provides a darker colour, which is visually reminiscent of roasted ground coffee.21 cl, 17 dwg, 13 tblГр
