FIELD: food industry.SUBSTANCE: invention relates to a method for preparation of a sublimation-dried aerated milk or milk-substituting composition including stages as follows: provision of a milk or milk-substituting ingredient; emulsifier addition; thermal treatment of the mixture produced; the mixture fermentation; a gas admixture to the fermented mixture; continuous and simultaneous aeration of the mixture with the gas and the mixture whipping until its final overrun degree varies from 30 to 50% to produce an aerated composition; formation of portions of the aerated composition having a preset shape, the diameter amounting to 13-22 mm, height - to 7-12 mm and weight - to 0.8- 1.3 g; the portions cooling and sublimation drying. Bt way of the said method one produces sublimation-dried aerated milk or milk-substituting composition containing at least: milk or a milk-substituting ingredient, an emulsifier and a viscosity booster; the composition has a strength value at maximum load varying from 0.5 to 8 pounds force and solubility within the maximum load range from 0.1 to 8 pounds force. By way of the said method one ensures production of a sublimation-dried aerated milk or milk-substituting composition containing at least milk or a milk-substituting ingredient as well as 0.001-1 wt % of lactilated mono- and diglycerides.EFFECT: invention ensures production of a sublimation-dried aerated fermented and physically stable product having an optimal balance of viscosity, strength and solubility.33 cl, 3 ex |
