Abstract

Objective : Kyenegum has been frequently used for characterizing digestive symptoms in the traditional and oriental medicines. This study was conducted to investigate the characteristics of extracts from velvet antlers using the 4 different kinds of extracting methods. Methods : The extracts of velvet antlers were extracted using a $65^{\circ}C$ DW (9hrs), a Kyenegum crude enzyme, a $121^{\circ}C$ DW (2hrs), and a Kyenegum protease. To evaluate the characteristic of velvet antler extracts, we examined the brix, soluble solid, amino acid, mineral composition, and collagen protein. Results : As a result of the comparisons of velvet antlers extracted by the traditional extraction and the crude enzyme of kyenegum, the brix and soluble solid showed the higher contents for kyenegum enzymes. Also, mineral contents of the extracted velvet antlers were higher, particularly in Ca and P for those. The contents of collagen protein, hydroxyproline and hydroxylysine, were found to be more than twice in kyenegum protease compared with other extracting methods. Conclusion : These results indicated that the Kyenegum crude enzyme and protease are very effective to extract of velvet antlers.
