Fig. 1 is a block diagram illustrating a method of manufacturing a color-coated roasted bird egg according to an embodiment of the inventive concept, Fig. 2 is a block diagram illustrating a method of manufacturing a color-coated roasted bird egg according to another embodiment of the inventive concept, Fig.3 is a front view illustrating a bird egg of which surface is coated with water soluble shellac and color solution, and Figs. 4 and 5 are front views illustrating bird eggs of which surface is expressed by pictures.

As shown in Figs. 1 and 3, the method of manufacturing a color coated roasted bird egg according to the inventive concept S100 comprises cleaning a surface of a bird egg using cleaning water S110; aging the bird egg cleaned by the cleaning water for 40~50 hours at 40°C~50 °C S120; applying water soluble shellac to coat on the surface of the bird egg cleaned by the cleaning water S130; drying the bird egg coated with the water soluble shellac for 4~6 hours at room temperature S140; applying color solution to coat the surface of the dried bird egg S150; drying the bird egg coated with the color solution for 6~8 hours at room temperature S160; and heating the dried bird egg for 50~60 hours at 120℃ ~ 150℃ S170.

The cleaning S110 is a step for cleaning the surface of the bird egg 100 using cleaning solution.

The bird egg may be a quail egg, a duck egg or an ostrich egg.

The bird egg 10 before the cleaning may be distributed with bird's feces, feather and a lot of impurities and contaminated additionally in distribution process.

In specifically, the cleaning 110 remove bird's feces or additionally contaminated impurities or contaminations by cleaning using hand rubbing or apparatus such as a brush and cleaning solution.

The cleaning solution used in the cleaning S110 may be cleaning solution treated using an advanced oxidation process.

The advanced oxidation process (AOP) is a technology that 253.7㎚ of violet wave length and 184.9㎚ of ozone generating wave length are simultaneously generated in a discharging lamp, coupled with oxygen in the air and performed optical decomposition to generate a large quantity of hydroxyl radical and treat oxidation. This is a sterilization technology using oxidation reaction of the hydroxyl radical generated by AOP discharging lamp.

A method of cleaning the bird egg 10 using water treated by AOP can clean extraneous substance on the surface of egg shell of the bird egg 10 by cleaning and sterilization, and has an advantage of sterilizing bacilli on the surface of egg shell of the bird egg 10.

The cleaned bird egg 10 is soaked in salt water or diluted fruit water.

When the bird egg is soaked in the salt water at least for 1 minute, the salt water may be permeated through pores of the bird egg 10. Then salinity of salt is covered such that the bird egg can be eaten without salt even if the ageing and coating is implemented.

The bird egg is corruptible under certain period. However, the bird egg can be preserved for long period without corruption if the bird egg is soaked in the salt water.

Concentration of salt may be differentiated according to environment change. 10~14% of salt concentration may be used in spring, summer and autumn, 15~20% of salt concentration may be used in winter. Since salt concentration is low in spring, summer and autumn, it is preferable that the bird egg 10 is soaked in the salt water for short time in winter.

When the bird egg 10 is soaked in the diluted fruit water of an apple, a peach or a strawberry for at least 1hour, the fruit water is permeated through pores of the bird egg 10 such that white and yellow of the egg can be changed in color.

The bird egg 10 soaked in the fruit water can produce beauty by various color to provide quality improvement.

Concentration of salt or fruit water may be increased by soaking time in the salt water or fruit water.

The aging S120 is a step for aging the bird egg 10 cleaned by the cleaning solution for 40~50hours at 40℃~50℃

The aging S120 provide characteristics matched with target food by leaving the bird egg 10 with insufficient flavor and texture in condition of suitable temperature and time.

In aging S120, moisture in the cleaned bird egg 10 is reduced suitably such that a shell can be peeled easily and fleshiness of bird egg 10 becomes chewy to raise an appetite.

The coating S130 is a step for applying and coating the surface of the aged bird egg 10 with the water soluble shellac 100.

The coating steps S130 and S150 may be separated as a first coating S130 in which the water soluble shellac 100 is applied and coated and a second coating S150 in which color solution is applied and coated.

The water soluble shellac 100 in the first coating S130 is coated on the surface of the bird egg 10 to prevent alcohol from evaporation and increase contact time of alcohol and bacilli such that sterilization of all bacilli is provide and conservation of the bird egg 10 is improved.

The water soluble shellac 100 is a natural resin which is harmless to human and recognized by FDA, and widely used in pharmacy, confectionery and fruit coating agent.

The water soluble shellac 100 is more soluble with alcohol rather than water. Thus alcohol may be used as a solvent.

The surface of the bird egg 10 after aging may be coated with water soluble shellac 100, and the water soluble shellac 100 may be substituted by one of alcohol, wood vinegar or propolis.

The alcohol may be one of methyl alcohol, ethyl alcohol, butyl alcohol, isopropyl alcohol. Ethyl alcohol without harmful for human is preferable.

The alcohol is used as a solvent for dissolving the water soluble shellac 100 and also has a function of sterilizing bacilli on the bird egg 10. If the bird egg 10 is cleaned by only alcohol, bacilli on the surface of the bird egg 10 are partially removed caused by sterilizing function of the alcohol. However, alcohol has short period to contact with bacilli because of rapid evaporation thereby sterilization effect is very low.

In a process of making charcoal from wood, smoke is liquefied to be wood vinegar. When wood is burning and producing smoke, an entrance of a kiln is closed with remaining a small vent hole. Then the smoke from the vent hole contacts with outer air to be cooled naturally thereby liquid is dropped to be the wood vinegar.

The wood vinegar in the inventive concept affects inner ingredients of the bird egg 10 to purify heavy metals and to be a deodorant during keeping in a refrigerator.

It is known that the propolis has various remedial effects. Typical effects are ant-inflammatory, antibiosis, anti-oxidation, cell restoration, tissue restoration. Recent research has introduced about cancer control effect that perform an auxiliary role to control a cancer.

The sterilization function of the coating component on the surface of the bird egg 10 may be doubled by the sterilization of the propolis. In addition, secondary bacilli contamination can be prevented during distribution process of the bird egg 10 and the sterilization effect can be maintained and improved because the propolis does not evaporate from the mixed composition solution.

The drying S140 is a step to dry the bird egg 10 coated with the water soluble shellac 100 for 4~6hours at room temperature.

In the drying S140, the bird egg 10 coated with the water soluble shellac 100 may be dried at room temperature such that the water soluble shellac 100 is toughly welded on the surface (shell) of the bird egg 100.

The second coating S150 is a step to coating the surface of the dried bird egg 10 with a color solution 200.

The color solution 200 in the second coating S150 may be liquid form by mixing with 20 w% of color powder, 50~70w% of water soluble shellac and 15~25w% of alcohol.

The color power over 20 w% may produce natural color and be capable of mixture at least two colors to produce beauty.

Specifically, the color powder may be formed from natural mineral matter and manufactured by selecting one color from gold, silver or chocolate color.

As described above, the water soluble shellac 100 may be a natural resin which is harmless to human and recognized by FDA, and widely used in pharmacy, confectionery and fruit coating agent.

If the color solution 200 mixed with water soluble shellac 100 and alcohol is coated on the surface of the bird egg 10, alcohol is not evaporated for sufficient period while alcohol in the coating layer penetrates cell membranes of bacilli and coagulates protein to sterilize bacilli. Thereby, remained bacilli of the bird egg 10 can be sterilized.

The color solution 200 in the second coating S150 may be liquid form by mixing with 20 w% of color powder, 20~30w% of water soluble shellac and 15~13w% of alcohol or by mixing with 30 w% of color powder, 30~40w% of water soluble shellac and 20~30w% of alcohol. However, the color solution described above is preferable to produce natural color and most elegant beauty.

The second coating S150 may provide effectiveness that salmonellae as well as normal bacilli and colon bacilli can be sterilized at 99.9% and discoloration is prevented and a coating portion is not peeled.

The thermocolor is a dye which is changing color in accordance with temperature and is powder form. As temperature is increasing, an original color is removed or changed into another color and the original color is returned or generated as the temperature is decreasing.

The preserved condition of the bird egg 10 may be verified by eyes using the state of the thermocolor in accordance with temperature.

For example, the bird egg 10 coated with thermocolor maintains white color at normal state and changed into red color to indicate sanitary or unsanitary states in accordance with preserved condition.

A person, who recognizes an unsanitary bird egg throws away it to prevent another person eating it without knowing. The thermocolor may be changed into yellow before changing into red from white such that the progress state of fault is indicated to people in advance, and then preparation can be prepared.

The color may be formed of reversible color (dye) or irreversible color (dye). The difference of the reversible color and irreversible color is whether the color is changed as increasing temperature and the color is reversible or not as decreasing temperature.

The reversible color can use repeatedly because the original color is returned, but the irreversible color is one time that is not returned to the original color.

The dye may be dyed a color with fastness to a fiber or other materials.

The food coloring may be formed of artificial coloring and natural coloring and is harmless to human because the food coloring is assigned as food additives.

The artificial coloring may be a coloring which produces a color same as the natural color, and may be classified into tar group and non-tar group.

The drying S160 is a step to dry the bird egg 10 coated with the color solution 200 for 6~8hours at room temperature.

Specifically, in the drying S160, the bird egg 10 coated with the color solution 200 may be dried at room temperature of 20℃~30℃ to weld toughly on the surface (shell) of the bird egg 10 coated with the color solution 200.

The heating S170 is a step to heat the bird egg 10 after drying for 50~60hours at 120℃~150℃.

Specifically, the heating S170 may use a heating apparatus such as a kiln to make the bird egg 10 after drying into a roasted bird egg such as a stone-plate cooked egg. The product may be completed after heating the bird egg for 50~60hours at 120℃~150℃.

In the heating S170, the bird egg 10 may be heated with increasing heating temperature slowly without increasing heating temperature rapidly.

For example, the heating temperature may be increased to 120℃ ~ 150℃ from 80℃ for 2hours, 90℃ for 3hours and 100℃ for 4hours.

The reason of phased heating is that the shell of bird egg 10 may be broken or cracked by rapid elevation of inner steam pressure if the heating temperature is increasing rapidly. If the heating temperature is increasing from low temperature to high temperature in phases, the inner steam pressure of the bird egg 10 is increasing in phases to prevent the shell of the bird egg 10 from being broken.
