COMPARATIVE ANALYSIS OF METHODS FOR PRESERVING EMBRYOS OF ANTLERED DEER
A method for preserving embryos of antlered deer using vacuum equipment at the temperature of 40-45°C and pressure of 1 atmosphere has been revealed to be optimal. Period of time for drying 1 g raw material and obtaining finished products has been determined. Investigations on biochemical characteristics and biological activity of powders from embryos were carried out as compared with the traditional preservation method, infrared and freeze drying. Biochemical characteristics of powder substances obtained at preservation in vacuum dryer are optimal as to fat and ash contents and amino acid ration, exceed the data of infrared and freeze drying as to E vitamin content almost 2 times and B vitamin content 1.6 times. The content of mineral substances at vacuum drying is at a sufficiently high level, the macro elements content is 1.2 times higher than that at infrared and freeze drying, microelements 2 and 1.7 times, respectively.
