FIELD: food industry.
SUBSTANCE: invention relates to primary processing of medical-and-technical raw materials, namely to preservation of reindeer unossified horns (antlers). Reindeer unossified antlers preservation method includes freezing, thermal treatment using infrared radiation spectrum till normal moisture content is reached. Unossified antlers, frozen at -20-24°C are sawn into plates 0.5-0.7 mm thick, put on reticulate cassettes (without defrosting) and thermally treated with active ventilation at wave length 1.6-2.4 mcm, 6 hours and at 45°C. After that they are left for cooling during 12 hours, plates are turned over and thermal treatment process is repeated till production with moisture content 12-19% is obtained.
EFFECT: invention provides for production of high-quality raw material with high content of biologically active substances, reduction of technological operations amount and preservation time.
