Description

Tactile dipping processing method of cherry leaf

The present invention relates to a method of tactile dipping of cherry leaves.

Conventionally, the dipping process of cherry leaves has been used for food cooking as confectionery or edible material. When used for such application, the appearance reddish color of the dipping process has the same vivid color on both sides of the surface. ) Or fresh rubber color, so that the flavor (flavor) is well retained.

To this end, conventionally obtained by dipping cherry raw leaves in bome (aqueous solution of magnesium) of boome 16 °, but in recent years, it is difficult to obtain the water, the processing method of using the water is difficult As a result, the use of separate processing methods without using guards was required.

This separate processing means that cherry leaves are soaked in saline at 16 ° saline (high saline immersion) for 2-3 months and then immersed in saline at 10 ° saline (low saline immersion) at 2 ° for 2 days. Then, after immersion (medium immersion) for 10-13 days in the saline of Boomero 16 ° again, and then performing the above-described low saline immersion for 2 days again, the intermediate immersion described above is performed for 10-13 days, again for 2 days After repeating the low concentration saline immersion and the intermediate immersion for 10-13 days several times, the final saline immersion of the cherry leaves was obtained by performing the above high concentration saline immersion. Thus, the conventional processing method not only requires a long period of 5 to 6 months for immersion processing, but is also desirable such that the color tone of both sides of the processed cherry leaves becomes uneven and clear brownish. There was also a dismissal. Such undesirable end of whitening can be changed to a clear raw rubber color by immersing the processed product of the whitening in hot boiling water for 1 to 2 minutes. However, such hot water treatment has caused severe deterioration in quality because it is remarkable to lose the original flavor of the processed product. On the other hand, it is also possible to repeat 5-6 months alternating low and high salt soaks in order to obtain a processed product that retains the original flavor and aroma of cherry leaves, but sometimes microorganisms occur during low salt soaking. The quality is extremely deteriorated.

As described above, in the conventional immersion processing method, there is no simple processing method that does not damage the natural flavor and fragrance of cherry leaves and makes the appearance uniform and vivid starry or raw rubber color. The unclear white brown resulted in a significant reduction in the value of the product and, in some cases, an unusable workpiece, resulting in a significant economic disadvantage for the processor.

The inventors have diligently studied the method of obtaining sake immersed products of good quality by ameliorating some of the above-mentioned shortcomings, and surprisingly, the fresh leaves of cherry blossoms were put in an aqueous medium such as water or saline in an airtight container, By dipping under reduced pressure in the medium and immersing it in the aqueous medium again if necessary, there is no pulmonary pulverization, which is a conventional pulmonary end, and has a good flavor and aroma. It has been found that a cherry leaf processed product having a uniform color is obtained, in particular, the aqueous medium is an aqueous solution having a specific gravity of 8-16 degrees of water or boomer, and is carried out under conditions in which the pH is neutral to acid. It has been found that a very good cherry leaf immersion processed product is obtained and there is no decaying waste end. In addition, when the aqueous medium is water or boomer 8 degrees or less, it was found that the same degree of sapling process of sakura cherry leaves obtained by immersion in the aqueous medium of boomer 16 degrees after decompression.

The present invention has been completed on the basis of the above-mentioned contents, and the uniform color and vivid star color are characterized by immersing the fresh cherry leaves in the aqueous medium in the airtight container and continuously depressurizing them, and then immersing them in the aqueous medium which is a non-toxic aqueous solution. Or it is the immersion processing method of the cherry leaf which has a raw rubber color, The objective is to provide the immersion processing method of the cherry leaf which has favorable commodity value in a short time.

First of all, exemplifying the practice of the present invention, it is easy to make a bunch (about 60-140 grams) of the fresh leaves of cherry blossoms by binding about 50-100 pieces, and to adjust the bundles of each according to the volume of the airtight container, For example, it is easy to use 1000 bundles (about 60-140 kilograms) industrially, and the number of use of the bundle is increased or decreased as needed. The selected cherry leaves are sufficiently washed with water, filled into a container, and then injected with an aqueous medium. The amount of injecting the aqueous medium is such that the previously filled cherry leaves are sufficiently positioned below the surface of the water. In this case, it is preferable that the cherry leaves are sufficiently immersed, for example, by using a suitable weight (eg, mediation). .

As the aqueous medium to be used, water or a non-toxic salt aqueous solution is used, and as the non-toxic salts, salt is preferable, and other ones such as potassium chloride, calcium chloride, sodium sulfate, sodium phosphate, or salts thereof may be used in combination. In addition, the non-toxic salt aqueous solution may have a specific gravity of 8 ° or more of bome, and in particular, it is preferable to prevent decay in a long time by using an aqueous solution having a specific gravity of 12 ° of bome. When the same specific gravity is used, decay of the cherry leaves is prevented, but the soaking time is prolonged, and the preferred concentration of the salt solution is an aqueous solution of 8-16 degrees or 12-16 degrees of boomer. And in order to adjust the pH, it is preferable to add alum, citric acid (citric acid), ascorbic acid and the like to the aqueous medium to adjust the pH to about 5 is used. In particular, in the case of bringing the aqueous medium to pH 5, the color of the desired workpiece increases in vividness and is performed in a short time.

The aqueous medium is filled into an airtight container, and the cherry leaf is immersed in the air and then depressurized. As the airtight container to be used, an airtight container having a capacity of sufficiently filling the required amount of cherry leaf leaves is preferable. Fresh leaf) 50 sheets in a bundle If you want to fill 1000 bundles, you need to fill up to 500 liters of aqueous medium so that you can reduce the pressure by using a steel or stainless steel raised mill that is about 100 × 75 × 80 cm. A container containing 100-200 bundles of cherry leaf leaves can also be put in a hermetic container and depressurized. The degree of decompression is to depressurize the cherry leaves immersed in an aqueous medium, that is, to depressurize the air in the airtight container, and the decompression conditions are related to the decompression time, for example, decompression for 1 minute or more at 700 mmHg or more. It is preferable to reduce the pressure at 750 mmHg for 2 minutes. As a vacuum pump for pressure reduction, a general thing, for example, Genko Seiki Co., Ltd. type SR-800 (exhaust capacity 803 liters / minute) can be used. Next, it is immersed in an aqueous medium. At this time, the aqueous medium may be used as the above-described aqueous medium, and it is preferable to use an aqueous medium of Boomer 12-16 degrees, especially an aqueous medium of Boomer 16 degrees as an immersion liquid. . In addition, the pH of the immersion aqueous medium is about 3 acid, so this acid does not need to be neutralized (pH 7) because it suppresses the growth of decaying bacteria.

As described above, the aqueous medium has the best result when the water medium is about 16, but when the aqueous medium is less than 8, it may decay. However, before decay begins, it is preferable to immerse the treated water in an aqueous medium having a pH of about 3 degrees and having the same kind of salt dissolved therein.

As described above, immersion in the aqueous medium at pH 3 and Boomer 16 degrees is completed for 20-40 days of total immersion days, preferably at least 30 days at room temperature to prepare the cherry leaf immersion process of the present invention. As a result, the obtained cherry leaf immersion does not lose the flavor and aroma of its leaves, and the color of the immersion does not become uneven or uneven white brown color on the front and back, and it is vivid tortoise or raw rubber and decayed. This is not a good thing, which is to obtain a better cherry leaf immersion workpiece in a short time than the conventional one.

Experimental evidence that the color of the immersion workpiece immersed in the brine by depressurizing treatment according to the present invention becomes raw rubber to star color is proved by the contrast experiment with the control described in Example 1. In addition, it is difficult to theoretically explain the color relationship, but it is certain that oxygen existing in the pores of the cherry leaves is removed by the depressurization degassing by depressurizing the cherry leaves of the submerged water. It is presumed that the prevention of the action of the oxidizing element and oxygen which converts the raw rubber-colored coloring material to yellow-white color causes the vivid raw rubber-color to star-red color.

The present invention is not limited only to these examples by the embodiment of the present invention below.

Example 1

With 50 pieces of fresh leaves (60-70 grams), each of which is bound together with its own leaf stems, 1000 bags are packed into a steel hermetic container (110 × 75 × 80 cm) and 500 liters of water is sold. do. In order to sink the cherry blossoms under the surface of the water, a wooden intermediary (middle, 97 × 72 × 3cm) is run over the surface of the water, and two wood chips (10 × 20 × 70cm) are placed on the surface. After sinking, the lid of the airtight container is sealed and immediately suctioned and decompressed with a vacuum pump (from Jinko Seiki Co., Model SR-800, exhaust rate 803 liters per minute) (750 mmHg, 2 minutes). This suction decompression operation was repeated twice to obtain 3000 batches of treated cherry leaves and divided into 500 groups of 6 groups.

On the other hand, for control purposes, 500 groups of 6 groups of control groups were prepared in the same manner as the above-mentioned treatment group except for the decompression treatment.

Next, prepare two groups of cherry leaves, each of which contains 500 bundles of 1 group, saline solution having a specific gravity of Boome 16 degrees, saline solution of Boome 8 degrees, water, and soaking liquids. After fusion, each group of cherry leaves is pressed down by the weight of the mediation, and the submerged parts of the cherry leaves are stored in a dark place (e.g., in a warehouse). Every 10 days after immersion, 2-3 bundles of cherry leaves are extracted to determine the state caused by the soaking of the cherry leaves. And one of them is neutralized by calcination to neutralize the pH of the solution to about 2.

As a result, the cherry leaf processed product of the present invention and the control group was prepared in the first table (present invention: pH 7), the second table (present invention: pH 3), the third table (control: pH 7), and the fourth table (control: pH 3). ) Is the same as displayed.

(Control: pH 7)

[Table 4]

(Control: pH 3)

± above is uneven and uneven starry or raw rubber color + is uniform and clear starry or green rubber color.

As indicated in Tables 1 to 4 above, the cherry leaves through the reduced pressure treatment of the present invention exhibit good, uniform and vivid star color or raw rubber color, especially those of pH 3 and saline concentration boomer 16 degrees Was not at all and was good.

In contrast, the control was only yellowish white or unclear and uneven. In addition, even in the immersion liquid at 8 degrees, in the present invention, the control group was poor in that the immersion liquid had good penetration by 20 days of immersion.

In addition, although the immersion liquid at 0 degree (immersion liquid is water) is recognized that both of the present invention and the control were decayed together, it was obtained through the reduced pressure treatment of the present invention to obtain cherry blossoms with better color in a shorter time. will be.

Therefore, even if the immersion liquid is pH 7 or pH 3 of the immersion liquid and the color of the immersion is 0 degrees or 8 degrees, the color development is preceded by the step of becoming uniform and vivid star color or raw rubber color. The cherry leaves without rot and immersed in immersion, as immersed in saline at 16 degrees Boe 16 as above Table 1, by immersing in saline at 16 degrees Boe, preferably pH 3 and Boe 16 degrees. Will be obtained.

As for the cherry leaf processed material processed by the processing method of this invention obtained in this way, although the period of immersion is shorter than a conventional thing, the flavor and fragrance which a cherry leaf immersion processed product retains it peculiar to the original green leaf, and the desired star color or raw rubber Since the color is shown uniformly and clearly, the quality is extremely good, making it ideal as an additive for confectionery and other dishes.

Example 2

Using a hermetic container used in Example 1 above and a medium-sized lid made of wood and wood lumber, a 1000 bundle of cherry leaves (unit bundle: 50 pieces each) were charged, and 500 liters of saline (pH 7) at 16 degrees was added thereto. After entering, the cap is closed and sealed, and the vacuum pump is operated to reduce the suction pressure (755 mmHg, 2 minutes).

Next, the saline solution of Boome 16 degrees is transferred to a wooden barrel filled and soaked for 30 days. The obtained product possesses the peculiar flavor and aroma of cherry leaves and is a good cherry leaf dipping process of uniform and clear starry to raw rubber color, without any decay at all.

Example 3

Fifty leaves of cherry tree are bound on the leaf stem and formed into unit bundles (approximately 60-70 grams), and 100 bundles of these are placed in a plastic container (capacity: 20 kg). Each brine with a specific gravity of 23 degrees is layered separately. And each place a wooden intermediary and wood chippings to immerse the bundle of cherry blossoms below the surface of the liquid, and then immerse them for 5 days, 20 days, 35 days.

Next, the above-mentioned immersion material is filled into a plastic container in a gas-tight container made of iron (110 × 75 × 80 cm), and sucked with a vacuum pump (Genko Seiki Co., Model SR-800, exhaust rate 803 / min). Reduce the pressure (750 mmHg, 2 minutes). Next, each of these is immersed in an aqueous medium which is an aqueous salt solution.

As a result, those obtained after 5 days of soaking are listed in Table 5, those obtained after 20 days of soaking in Table 6 and those obtained by 35 days of soaking are listed in Table 7.

In addition, using the saline solution adjusted to pH 5 by adding alum (alum) to this instead of each saline solution described above, the results are shown in Tables 8, 9, and 10, respectively.

As shown in the above Table 5-10, when the color leaves of the cherry tree are immersed by the decompression treatment, there is no white-brown portion which is generated, and again, the better immersion product is obtained by immersing it in the aqueous medium which is a saline solution.

In addition, in Tables 5-7, when the medium used is pH 7, and Table 8-10 is when the pH of the medium used is 5, when pH 5 is used, it is possible to obtain a workpiece in which decay is prevented in a shorter time.
