METHOD OF UNOSSIFIED ANTLERS PRESERVATION Russian patent published in 2011 - IPC A61L2/02 A01N1/02 

FIELD: process engineering.

SUBSTANCE: invention relates to preservation of unossified antlers used in pharmaceutical industry. Proposed method comprises water cooking of unossified antlers at the day of cutting off at 93-96°C by dipping them three times, cooling down between immersion and prolonged cooling after said immersions, wind cooling and extra cooling in vacuum drier at +50°C to residual humidity of 15%. Note here that, prior to water cooking, unossified antler butt is mashed by dry clay and cooking is performed of dipping whole unossified antler for 50-60 s, cooling for 50-60 s between dipping and 10-minute cooling after three immersions and repeating said cooking performed that very day with wind cooling after second cooking. Note here that unossified antlers are placed, on second day, into vacuum drier to keep them therein at 0.1 atm with 0.1 atm-increase of vacuum every 5 hours of 30 hours.

EFFECT: higher quality of target product.
