Description
The present invention relates to a fermented persimmon for use as a natural coloring agent for dyes and paints, and more particularly to a method for producing a fermented persimmon by anaerobic fermentation of the juice with yeast and a dye and a coating composition using the fermented persimmon preferably will be.
Persimmons have traditionally been used to dye fibers as dyes. Traditional persimmon dyeing is a method using fermented persimmon fermented in nature for 1 to 3 years. However, this method not only takes a long time to obtain the fermented persimmon, but also has poor color development. In addition, there is a disadvantage that the persimmon-dyed fiber structure is stiff, and the permeation dye is easily peeled off due to the low adsorption rate of fermented persimmon.
In order to improve the disadvantages of the conventional conventional fermented persimmon fermented persimmon production method using a useful microorganism has been introduced in Korean Patent Publication No. 10-2009-86856. However, this method has a disadvantage that the fermentation time is still long, about 15 to 60 days, and the adsorption rate is not significantly improved. Also, a large amount of acetic acid is generated during the fermentation process, which may damage the fiber which is the dye.
The present invention has been developed to improve the shortcomings of the conventional fermentation has the following technical problems.
First, the fermentation time is to provide a method for producing a short fermented persimmon.
Second, to provide a method for producing a fermented persimmon having a short color development time, high adsorption rate and stable color development.
Third, to provide a dye and paint preferably using the fermented persimmon.
In order to solve the above technical problem, the present invention provides a method for preparing fermented persimmon using yeast and a dye and a coating composition including the fermented persimmon.
Fermented persimmon production method according to the invention, the first step to make the juice by juice persimmon; Anaerobic fermentation of the juice of the first step with leaven fermented by the second step;
The dye composition according to the present invention is characterized in that the lye is mixed with the fermented persimmon prepared according to the above method.
The coating composition according to the present invention is characterized in that the lye and mucus are mixed with the fermented persimmon prepared according to the above method.
According to the present invention, the following effects can be expected.
First, since the development of anaerobic fermentation with yeast promotes tannin's own oxidation by temperature rise, it is possible to quickly produce fermented persimmons that can reduce the color development time and reduce the influence on external conditions.
Second, since the alcohol produced during the anaerobic fermentation of yeast decomposes tannins and fibers, fermented persimmons that can increase the adsorption rate of chromium tannins can be prepared.
Third, since the fermented persimmon by yeast is mixed with lye in dye or paint, the volatilization of alcohol produced during fermentation can be suppressed with lye. Since it can hold | maintain, dye or coating material which has stability of color development can be provided.

The present invention has a technical feature to prepare the fermented persimmon fermented with Nuruk. Specifically, the fermented persimmon production method according to the present invention, the first step to make the juice by juice persimmon; Anaerobic fermentation of the juice of the first step with leaven fermented by the second step;
The second step can be carried out while using the yeast culture solution obtained by floating the yeast in the medium, in the present invention was used the yeast solution obtained by floating the yeast in the medium mixed with water and malt. In addition, the second step, it is preferable to proceed with the fermentation for 5-15 days at a temperature of 5 ℃ ~ 30 ℃ and until the pH of the fermentation persimmon is 3 ~ 3.5, which is the alcohol fermentation by yeast This is to prevent acetic acid fermentation by acetic acid bacteria after the occurrence. After the fermentation proceeds, the third step of ripening at a temperature of 5 ~ 10 ℃ can be carried out.
As described above, the fermented persimmon can be used as a dye or paint after neutralizing the lye, and the fermented persimmon and soybean lye are strongly stirred by a stirrer (magnetic stirrer). However, when used as a dye or paint can be further mixed with the dispersant and the mucus function as an adhesive, in the embodiment of the present invention is used as a lye and mucus, soybean lye and sulfur mucilage, respectively, to complete a natural dye or natural paint . When used as a dye or a paint, it is preferable to apply at 25 to 60 ℃ while increasing contact with air as much as possible. This is to maintain the stability of coloration by allowing the fermented persimmon to be oxidized by oxygen in the air and promoted by temperature. To do this.
Example 1 Change in Absorbance
1 to 2 are graphs showing the change in absorbance of the persimmon extract according to temperature or pH.
Figure 1 shows the change in absorbance at 312nm when the persimmon extract is decompressed by ultrasonic treatment to remove dissolved oxygen and then replaced with nitrogen and left at 25 ~ 80 ℃, the same tendency to increase the colorless tannin oxidized You can see the color development. In particular, at a high temperature, the largest absorbance is observed at about 1 hour, and at that time, the absorbance is rather decreased. This is because the colored material produced by oxidation is insoluble and precipitates as the oxidation proceeds further. In addition, since Figure 1 is a result of removing dissolved oxygen, the oxidation of tannin, which occurs at this time, may be seen as self oxidation in the tannin molecule rather than oxidation by oxygen in the air. It can be seen that it is promoted accordingly.
2 shows the change in absorbance at 216 nm when the persimmon extract is strongly stirred with a stirrer to increase contact with air as much as possible and is left at 25 to 60 ° C., compared with FIG. It can be seen that it is promoted by the temperature.
Figure 3 shows the change in absorbance according to pH at 30 ℃, it can be seen that there is almost no change in absorbance according to pH as shown.
1 to 3, it can be seen that tannin, which is a main pigment component of persimmon extract, is oxidized by oxygen and light in the air and is promoted by temperature.
Example 2 Preparation of Fermented Persimmon
(1) Persimmon, persimmon leaf, and persimmon peel were crushed with a crusher.
(2) A juicer was filled with a juicy juice using a press machine.
(3) The yeast culture solution prepared in advance in a rubber bucket filled with juice was poured at a rate of 4-5% of the juice amount (Fig. 4). The yeast culture solution was crushed into a 1kg yeast tube in 20ℓ of water a day or two before, and 200g of fine gold was used.
(4) The rubber inlet was tightly covered with a cloth and a lid to be sealed and fermented while maintaining a temperature of 28 ° C to 30 ° C for one week. 5 is a photograph taken the fermentation of the fourth day.
(5) It was aged and stored in a low-temperature storage at 7 ℃.
Example 3 Dyeing and Painting with Dyes and Paints
1. Making lye
Lye was made as soybean as in Figure 6, soybean lye was prepared before and after pH11.
2. Dyestuffs and Dyeing thereby
The fermented persimmon prepared in Example 2 was strongly stirred with a stirrer (magnetic stirrer) at a weight ratio of 1: 1 with soybean lye to prepare a dye. This dye was spray dyed onto silk fibers, and FIG. 7 shows the dyed silk fibers.
3. Painting by paint
The fermented persimmon prepared in [Example 2] was mixed with the soybean lye at a weight ratio of 6: 1, and the viscosity was adjusted with a sulfur slime to prepare a paint having an appropriate viscosity. This paint was painted onto the pine with a brush, and Figure 8 shows the painted pine.
