Description
METHOD OF PREPARING DEER BONE EXTRACT HAVING INCREASED
AMOUNT OF GANGLIOSIDE
BACKGROUND
1. Field Embodiments of the present invention relate to a method of preparing a deer bone extract in which deer bones are subjected to extraction at normal pressure and extraction under pressure in order to minimize decomposition of deer bone-derived gangliosides by heat and to increase protein extraction yield.
AMOUNT OF GANGLIOSIDE
BACKGROUND
1. Field Embodiments of the present invention relate to a method of preparing a deer bone extract in which deer bones are subjected to extraction at normal pressure and extraction under pressure in order to minimize decomposition of deer bone-derived gangliosides by heat and to increase protein extraction yield.
2. Description of the Related Art According to Shennong classics of material medic, deer bones have a warm temper and are sweet-tasting and non-toxic, and thus, when administered after boiling, the boiled deer bones are capable of treating all kinds of diseases caused by muscle weakness and poor bone function due to general weakness in the body.
Recently, it has been discovered that lean meat and general bones of deer have also contain functional ingredients. In particular, analysis results show that deer bones contain approximately 40% gangliosides, which are known to be contained only in deer antlers. As a result of analysis of ganglioside ingredients, it has been confirmed that deer bones contain 5.66 mg/g of gangliosides, male deer bones contain 0.77 to 2.87 mg/g of gangliosides, and elk deer bones contain 0.92 to 2.31 mg/g thereof. Gangliosides are known to maintain and activate physical function, which activates brain cells together with hemoglobin to thus enhance brain function, improve memory and concentration, and boost immunity. In addition, recent clinical data report that gangliosides improve Parkinson's symptoms and relieve diabetic peripheral neuropathy.
A deer bone extract contains large amounts of main ingredients involved in skeletal formation and metabolism, i.e., protein, phospholipids, and the like and also contains chondroitin, collagen, and the like, and thus, it helps bone and joint health.
In addition, the deer bone extract contains inorganic components, i.e., calcium and phosphorus, and thus enhances nervous system function and facilitates metabolism.
As to research on deer bones, there have been disclosed a method of extracting gangliosides using deer meat and deer bone (Method of preparing a concentrate by using deer meat and deer bone and a food prepared using the same, Korean unexamined published Patent No.: 1020040035336), an extraction method used to prepare a deer bone extract from which fishy odor is removed by including an herbal medicine (Method of preparing a deer bone extract containing an herbal extract, a deer bone extract prepared using the method, and food and medicines including the deer bone extract, Korean unexamined published Patent No.:
1020050104876), an extraction method using deer antlers together (Healthy drink including a deer bone extract and a method of preparing the same, Korean unexamined published Patent No.: 1020100088797), an extraction method using a mixture of deer antlers, deer flesh, and deer bone (Method of preparing a double-boiled deer extract, Korean unexamined published Patent No.: 1020110069622), a method of effectively removing fishy odor of deer bones by extracting protein from a deer bone extract (Method of preparing a deer bone extract, Korean unexamined published Patent No.: 1020130119224), and the like. However, there has been no research into a method of minimizing the decomposition of gangliosides by heat and increasing protein extraction yield by using deer bones alone.
SUMMARY
Therefore, it is an aspect of the present invention to provide a method of preparing a deer bone extract in which gangliosides, which exhibit poor thermal _ resistance, are extracted at a maximum level by extraction at normal pressure and are also extracted under pressure to increase protein extraction yield, and thus, the amount of gangliosides and protein extraction yield are increased.
Additional aspects of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.
In accordance with one aspect of the present invention, a method of preparing a deer bone extract includes performing hot water extraction on deer bones at normal pressure, performing hot water extraction on the deer bones under pressure, separating oil from the extract, filtering the oil-separated solution, and concentrating the filtrate.
The hot water extraction at normal pressure may be performed at about 95 to about 105 C for about 3 to about 12 hours after mixing the deer bones and purified water in a weight ratio of about 1:1.5 to about 1:7.
The hot water extraction under pressure may be performed at about 105 to about 140 C for about 0.5 to about 12 hours after mixing the deer bones and purified water in a weight ratio of about 1:1.5 to about 1:4.

DETAILED DESCRIPTION
Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout.
A method of preparing a deer bone extract, according to an embodiment of the present invention, will now be described in detail.
First operation: Removal of blood from deer bones Deer bones and purified water are mixed in a weight ratio of about 1:1.3 to about 1:3 and blood is removed from the deer bones for about 2 to about 12 hours.
This process is repeated two to four times.
Second operation: Hot water extraction at normal pressure The deer bones from which blood has been removed in the first operation and purified water are mixed in a weight ratio of about 1:1.5 to about 1:7 and subjected to extraction at about 95 to about 105 C for about 3 to about 12 hours.
When deer bones are subjected to normal pressure extraction at about 95 to about 105 C for about 3 to about 12 hours, decomposition of gangliosides by heat may be minimized and the total extraction yield of gangliosides may be increased.
Third operation: Hot water extraction under pressure The deer bones obtained after hot water extraction at normal pressure has been performed in the second operation and purified water are mixed in a weight ratio of about 1:1.5 to about 1:4 and subjected to extraction at about 105 to 140 C for
5 about 0.5 to about 4 hours. To increase the temperature of an extraction vessel to about 105 to about 140 C, an inner pressure of the extraction vessel is set at about 0.5 to about 3 atm. When the deer bones are subjected to extraction under these conditions, the total amount of gangliosides may be maintained at 500 ppm or more and solids such as protein and the like may be efficiently extracted.
Fourth operation: Oil separation The extracts obtained after the second and third operations are maintained at about 60 to about 90 C for about 0.5 to about 4 hours and then oil is separated therefrom to remove a lipid layer. When oil separation is performed under these conditions, foaming induced by a large amount of protein is minimized so that oil separation and concentration processes are easily performed.
Fifth operation: Filtration The oil-separated solution is filtered using a vibro shifter including a 60 to 300 mesh filter. When the 60 to 300 mesh filter is used, precipitates derived from the deer bones may be effectively removed.
Sixth operation: Concentration The filtrate is concentrated at about 35 to about 70 C and about 0 to about 160 mmHg. Since concentration is performed in this temperature range, heat decomposition of total ganglioside, which is a functional ingredient, may be minimized. In addition, since concentration is performed in such a high vacuum (i.e., about 0 to about 160 mmHg), extraction efficiency of the deer bones may be increased. Moreover, when the concentration process is performed under these conditions, a natural color of the obtained deer bone extract may be retained and generation of bad odors is effectively inhibited.
Seventh operation: Drying The concentrate may be dried to form a powder. Here, the drying method is not particularly limited, and a general drying method such as vacuum drying, hot air

One or more embodiments of the present invention will now be described more fully with reference to the following examples and the accompanying drawings.
However, these examples are provided for illustrative purposes only and are not intended to limit the scope of the present invention.
[Example 1] Preparation of extract through normal pressure extraction 500 kg of deer bones were added to an extraction vessel, 1,000 L of purified water was added thereto, the deer bones were maintained in the purified water for 4 hours, the resulting solution was discarded, and blood was removed from the deer bones using cold water. These processes were repeated three times.
After the blood was removed from the deer bones using cold water, 3,000 L of purified water was added to the deer bones and the deer bones were then subjected to normal pressure extraction at 95 to 100 C for 4 hours.
First, to evaluate the relationship between extraction temperature and the total amount of gangliosides, the total amount of gangliosides during extraction at a temperature of 100 to 180 C for 1 hour was measured and results are shown in FIG.
2. FIG. 2 is a graph showing changes in the total amount of gangliosides during extraction at a temperature from about 100 to about 180 C for 1 hour. As illustrated in FIG. 2, the deer bone-derived ganglioside has poor thermal resistance.
Thus, it is confirmed that high temperature extraction is not desirable if extraction of gangliosides of deer bone is to be maximized.
FIG. 3 is a graph showing changes in the total amount and yield of gangliosides when deer bones are subjected to extraction at normal pressure and 100 C. As shown in FIG. 3, as extraction time increases under normal pressure, the total amount of gangliosides and solid yield increase. In addition, the total amount of gangliosides was greatest when the extraction time was 4 hours.
In addition, the relationship between the amount of water added and extraction amount when deer bones were subjected to normal pressure extraction
