FIELD: food and medicinal industry.
SUBSTANCE: invention relates to a method for preparing biologically active product of velvet antlers reindeer breeding. Velvet antlers is milled to particles size 0.5-1 cm3, mixed with deer blood and frozen to -50°C. Freezing and drying is carried out by effect of mechanical low-frequency oscillation with frequency 6- Hz, not less, and with amplitude from 5 to 12 mm by vibration of heat-exchange surface, for example, sublimator device plates wherein on this surface the raw is frozen and dried. Drying is carried out in regimen of temperatures from -50°C to +50°C and in the pressure range from 0.3 to 2 mm of mercury column. Method allows accelerating the drying process of raw taken in any ratios raw : blood, to enhance biological activity of ready product due to acceleration of the drying process, low temperature of drying, and to improve the technical grade quality and expand raw source in preparing biologically active supplements.
EFFECT: improved preparing method.
