METHODS FOR MANUFACTURING OF NATURAL PAINT WITH BLACK PERSIMMON COMPOSITION BY RIPENING TREATMENT}

The present invention relates to a method for producing a natural paint using a black persimmon composition prepared by ripening persimmon, and more specifically, using a black persimmon prepared by ripening, ripening, red fruit, red fruit, or maturity, and ripening it to make it transparent. Or it relates to a technique for producing a natural black paint having a high paint quality and stable physical properties as compared to the conventional manufacturing method by the opaque natural paint to produce.

In general, synthetic paints are mostly used to paint objects in various hues. However, since synthetic paints contain a large amount of various harmful components such as formaldehyde and organic compounds and cause environmental pollution, recent development and use of natural paints is increasing.

Currently, most of natural paints are developed in the Americas and Europe, and include resin-based resins such as lac resins and copal resins as alcohol solvents, protein-based compounds such as casein and egg white, which have high molecular weights, and cellulose. Polysaccharides or oils such as linseed oil and safflower seed oil are diverse and are very safe for human body.

On the other hand, in Korea, the syrup obtained from the juice is transmitted as a natural paint. It is considered to be the most representative paint along with lacquer because it has a high quality that paints the object several times and develops dark brown color while giving a soft luster.

In order to use persimmon, that is, persimmon as a paint, the collected persimmons are juiced, followed by fermentation and ripening. In general, the fermentation ripening of the juice takes a long period of 1 to 3 years, odors and impurities generated in this process has a problem that significantly lower the usability as a paint.

In addition, tannin, the main component of the juice, has condensation properties, resulting in the formation of red or brown precipitates by polymerization reaction with various products generated during the fermentation process, and gelation after fermentation to change into sludge. Storage is also extremely disadvantageous.

In addition, since only the process of fermenting and aging the juice is significantly lower in color development when used as a paint, it is cumbersome to repeatedly apply the coating several times, which requires a lot of time and labor during construction. There is no situation.

In recognition of the above problems, a technique for improving the physical properties by fermenting the juice using a yeast yeast or yeast yeast bar, for example, Korean Patent Laid-Open No. 10-2011-0097184 includes a fermented persimmon using yeast Dye and paint compositions are known and their specific details are as follows.

The first step of making the juice by juice persimmon and the second step of making the fermentation juice by anaerobic fermentation of the juice of the first step with yeast, the second step using the yeast culture liquid obtained by floating the yeast on the medium, but the medium It is characterized by a mixture of water and malt. In addition, the second step is made for 5 to 15 days at a temperature of 25 ℃ ~ 30 ℃ and after the second step further performs a third step of aging at a temperature of 5 ~ 10 ℃ and the fermented persimmon prepared according to Lye and mucus are mixed to prepare a paint composition.

Korean Laid-Open Patent No. 10-2011-0097184 (2011.08.31) Korea Patent Registration No. 10-1772601 (2017.09.13) Korea Patent Registration No. 10-1680480 (2016.11.28) Korean Patent Publication No. 10 -2009-0086856 (2009.08.14)

The traditional method of manufacturing a sicil according to the prior art is made in the form of juice by making persimmon juice, fermentation and ripening it.

The method for producing a natural paint using the black persimmon composition prepared by aging the persimmon to which the technique of the present invention is applied is an attribute of black persimmon using immature, fallen fruit, red fruit, or ripeness, and a natural paint is prepared using the black persimmon composition formed by ripening it. It is to be noted that the present invention relates to a method for producing a black persimmon paint having a high paint quality and stable physical properties as compared to the conventional method for preparing a paste.

The method for producing a natural paint using the black persimmon composition prepared by aging the persimmon of the present invention for this purpose, the first step (S10) to largely produce the black persimmon raw material, the second step (S20) for manufacturing the black persimmon composition using the black persimmon raw material and , Comprising a third step (S30) of manufacturing a natural paint using the black persimmon composition, specifically as follows.

The first step (S10) is a process of steaming the selected persimmon at a temperature of 60 ~ 90 ℃ to obtain a slime black persimmon and extrusion grinding to prepare a black persimmon raw material. In the first step (S10), the process of steaming in a humid state, and reducing the temperature by steam discharge is repeated several times to produce black persimmon as a property.

As shown in Figure 1, the first step (S10) is a preliminary steaming step (S11), the main steaming step (S12), the first to the fifth subsequent steaming step (S14 ~ S17) and the grinding step (S18).

The preliminary steaming step (S11) is a step of putting the persimmon removed water in a steamer in a humid state, steaming for 12 hours at 60 ~ 70 ℃, the steam is discharged to room temperature.

Persimmon used in the preliminary steaming step (S11) is used to wash the water after screening badness such as breakage or decay by passing immature feeling, falling fruit, red fruit, or ripeness. The washed persimmons are drained and placed in a colander and placed in a steamer.

In the preliminary steaming step (S11), the steamer proceeds at a temperature of 60 to 70 ° C. in a humid state of 60 to 98%. Be aware that the inflow of outside air during steaming and cooling (cooling) may affect the temperature and humidity due to changes in the amount of saturated steam.

As described above, the pre-steamed persimmon is water-soluble tannin contained in the cell is removed by steaming, and the tannin component is insolubilized while the fruit ripens. The degree of insolubilization may be arbitrarily adjusted and fixed according to the following main steaming step (S12) and the number of times and the conditions of the post-steaming step.

The main steaming step (S12) after the preliminary steaming step (S11), the steam is injected into the steamer to steam for 24 hours at a temperature higher than the preliminary steaming step (S11) for 24 hours, the steam is discharged to room temperature It is a step of temperature reduction.

The first subsequent steaming step (S13) is a step of steaming the steamer after passing through the main steaming step (S12), steaming for 48 hours at 60 ~ 70 ℃, exhausting the steam to reduce to room temperature.

As described above, when the steam is discharged, the volatiles contained in the persimmon are discharged together, and at the same time, as the moisture is reduced, the color of the persimmon is gradually darkened and matured into black persimmon.

The second to fifth post-steaming step (S14 ~ S17) after the first post-steaming step (S13), and repeating the steaming and temperature reduction for 72 hours, 96 hours, 122 hours, 144 hours at 70 ℃, respectively Step.

Through the steaming process as described above, the condensation tannin is stabilized by gradually reducing the steaming temperature and processing the steaming long, and various chemical components contained in the persimmon are destroyed and destroyed through the partial molecular structure change by pyrolysis. It is repeated to form the black color.

After passing through the fifth steaming step, the dark brown black persimmon with reduced water content can be stored in a vacuum, freezing, or hot air drying after being cut into pieces after refrigeration or rapid freezing.

The crushing step (S18) is a step of obtaining a black raw material to be added to the second step will be described later by stabilizing the mucus black black obtained at the fifth subsequent steaming step (S17) at room temperature for 3 to 5 days. to be. Since the black persimmon has evaporated moisture and the internal viscosity is very high, the black persimmon raw material is easily obtained by grinding the black persimmon having high mucus through the grinding step (S18).

On the other hand, the second step (S20) of the present invention is aerobic fermentation by adding water, sumizyme AC, tannase-KTFH, and Cytolase PCL5 to the black persimmon raw material obtained through the first step (S10), 15 ~ Concentrating to 30% by weight to prepare a black persimmon composition.

The second step (S20) is a process for producing a black persimmon composition in a stabilized state that the color development is dark and the physical properties are not modified by fermenting the black persimmon raw material, as shown in Figure 2 the composition step (S21) and the first The fermentation step (S22) and the second fermentation step (S23) and the concentration step (S24).

The composition step (S21) is a step of forming a black persimmon raw material liquid by adding 50 to 100 parts by weight of water with respect to 100 parts by weight of black persimmon raw material in a fermenter equipped with a stirrer.

The first fermentation step (S22) is the sumizyme AC 0.001 ~ 0.05 parts by weight, tannase-KTFH 0.001 ~ 0.05 parts by weight, Cytolase PCL5 0.001 ~ 0.05 parts by weight based on 100 parts by weight of the black persimmon raw material solution 50 ~ 60 Activate the enzyme for 30-720 minutes at ℃.

The sumizyme AC is a cellulase-based enzyme and is a hydrolase of cellulose constituting the third step (S30). As aerobic fermentation takes place, there is no odor.

The tannase-KTFH is an enzyme that decomposes the hydrolyzed tannin contained in the black persimmon raw material, thereby inhibiting insolubilization by fundamentally inhibiting the binding of the hydrolyzed tannin and the condensed tannin.

Cytolase PCL5 is a β-glucanase enzyme and has cellulase or pectinex activity. Therefore, there is a substrate property that breaks down the fiber from the tannins enclosed between the fibers. Gamma tannins separated from fiber are separated into water-soluble and insoluble tannins to minimize the possibility of aggregation.

The sumizyme AC, tannase-KTFH, and Cytolase PCL5 enzymes are preferably added to the black persimmon feed solution in the state of being dissolved in lukewarm water and subjected to catalytic reaction.

In the present invention, the use of a combination of the three specific enzymes as described above is generally due to the fact that the enzyme has a substrate specificity that selectively catalyzes only one reaction or a similar reaction. The first fermentation step (S22) is performed using sumizyme AC, tannase-KTFH, and Cytolase PCL5 enzymes optimized for fermentation. Therefore, the conventional yeast, such as the yeast of the prior art, eliminates the problem of causing an anaerobic fermentation reaction for a long time to cause decay and odor generation.

The second fermentation step (S23) is a step of losing the catalyst function by inactivating the enzyme for 10 to 30 minutes by increasing the temperature to 80 ~ 100 ℃ after the first fermentation step (S22). If necessary, the temperature may be increased to 100 ° C. or higher to kill microorganisms.

During the first fermentation step (S22) and the second fermentation step (S23), the fibers and pectin contained in the black persimmon raw material are enzymatically decomposed in a short time and the cause of the odor is removed by aerobic fermentation.

The concentration step (S24) is a step of centrifuging the black persimmon raw material passed through the second fermentation step (S23) and concentrating at low temperature at 55 to 60 ° C. in a vacuum concentrator to obtain a high concentrated black persimmon composition of 15 to 30% by weight. A pocket filter can be used instead of the centrifuge to filter foreign matter.

In addition, the black persimmon composition obtained through the concentration step (S24) is preferably sterilized by adding sodium benzoate as a preservative at about 103 ℃.

Residual organic acids and alcohol components generated through the first to second fermentation steps (S22 to S23), such as methanol, ethanol, propanol, iso-butyl alcohol, iso-amyl alcohol and acetaldehyde, are vacuumed. To remove from the condenser. Therefore, the concentration step (S24) to obtain a highly concentrated black persimmon composition of the stabilized state is minimized the components such as acetaldehyde listed above.

The black persimmon composition prepared according to the second step (S20) as described above is insoluble tannin between the fibers in the process of steaming the black persimmon in the first step (S10) is condensed in a paste state due to the low momentum insolubilized Polycondensation with protein or polysaccharide lectin inherent to prevent macromolecule binding, and in the process of mixing natural oils, minerals and natural pigments in the third step, it is possible to maintain a stabilized state by eliminating coagulation. have.

On the other hand, the third step (S30) of the present invention by mixing the persimmon to the black persimmon composition obtained through the second step (S20) to produce a transparent paint, or to the black persimmon composition natural pigments, natural material additives, It is a process to prepare opaque natural paint by mixing persimmon.

The persimmons to be mixed in the black persimmon composition is a conventional fermented persimmons, powdered persimmons, juice. As the conventional fermented persimmon can be used persimmon juice fermented for 1 to 3 years by juice persimmon as illustrated in the background technology, or the anaerobic fermented persimmon juice using yeast yeast, detailed description is omitted. do.

The natural substance additive used in the preparation of the opaque natural paint in the third step (S30), includes alginic acid, casein, shellac, gum arabic, linseed oil, glycerin, the first composition as shown in FIG. It comprises the obtaining step to the fifth composition obtaining step (S31 ~ S35), natural paint manufacturing step (S36), and after-treatment step (S37).

The first composition obtaining step (S31) is a step of dissolving the alginic acid and water in a 1: 10 weight ratio and then dissolved in a bath at 100 ℃. Alginic acid controls the viscosity of the paint.

The second composition obtaining step (S32) is a step of mixing the casein borax mixture with 15 parts by weight of borax added with respect to 100 parts by weight of casein and water in a 1: 7 weight ratio and then dissolving it in a bath. Casein adds adhesion to the paint and can be further mixed with alkaline and non-toxic borax.

The third composition obtaining step (S33) is a step of mixing 6 to 12 parts by weight of the first composition and 7 to 10 parts by weight of the second composition.

The fourth composition obtaining step (S34) is a step of adding 5 to 8 parts by weight of a mixture of 1: 2.8 parts by weight of shellac and alcohol with respect to 100 parts by weight of the third composition. Shellac is a natural finish, such as varnish, which gives a coating effect.

The fifth composition obtaining step (S35) is a step of adding 3 to 5 parts by weight of the mixture dissolved in a 1: 2.5 weight ratio gum arabic and water with respect to 100 parts by weight of the fourth composition. Arabian gum improves the adhesion of paints made of natural resins.

The natural paint manufacturing step (S36) is 6 to 10 parts by weight of linseed oil, 3 to 5 parts by weight of glycerin, and 10 to 20 parts by weight of persimmon with respect to 100 parts by weight of the fifth composition and stirred for 30 minutes or more. , 25 to 55 parts by weight of the black persimmon composition prepared in the second step (S20) is added.

The linseed oil added in the natural paint manufacturing step (S36) is preferably a dry oil such as voile oil. Boiled linseed oil provides a gloss effect, especially when painting the surface of wood, etc., and has a faster drying time than ordinary linseed oil.

The glycerin prevents freezing of the coating and controls drying. Instead of glycerin, propylene glycol having excellent solubility can be substituted.

Persimmon used in the natural paint manufacturing step (S36) may be used a conventional fermented persimmon or juice.

The post-treatment step (S37) is a step of adjusting the physical properties of the paint by adding a natural pigment and auxiliaries for color development to the natural paint. The auxiliary agent may include natural calcium, kaolin, sodium silicate, antisettling agent, dispersant, and the like to form the physical properties of the paint.
