Abstract
This study was conducted to investigate the proteolysis and extraction conditions of deer antler for application of food materials. ProteAX (A) was the most effective enzyme for proteolysis of deer antler and the proteolysis condition was 0.5% (w/w) for enzyme concentration and 5 hr for proteolysis time. The effect of mixing enzyme ProteAX (A)+KFEN 2 (C) treatment in , 5 hr was investigated; soluble solid and protein content were the highest with A 0.5% (w/w) and B 0.5% (w/w) concentration. Result for DAH (deer antler hydrolysate) and DA (deer antler) prepared with extraction in atmospheric pressure (AP, 6~18 hr) and extraction under pressure condition (UP, 15~60 min) after hydrolysis on preceding established condition descriptions indicated that difference in pH according to enzyme treatment and extraction conditions was not significant. Sugar content of DA was , DA-UP (under pressure) and DAH-AP (atmospheric pressure) were ; the highest sugar content of was observed in DAH-UP for 60 min extraction. Also total free sugar, crude protein and collagen content were the highest in DAH-UP for 60 min recording at 1.97%, 742.7 mg/100 g and 498.8 mg/100 g, respectively. From these results, deer antler hydrolysate prepared with extraction under pressure was the most effective for functional characteristics enhancement. Hereafter, various practical uses of materials with enhanced characteristics of antler is expected.
