Description

DETAILED DESCRIPTION OF THE INVENTION (A) Object of the Invention (a) Field of Industrial Application The present invention relates to a method for preserving fresh leaves of bear bamboo used for extracting bear bamboo extract containing chlorophyll (chlorophyll). .

(B) Conventional technology Bear bamboo grass used to extract bear bamboo extract is
For this purpose, I didn't think about any particular preservation, so there was no special preservation method.

However, as a treatment method for using the extract of bear bamboo as a herbal medicine, bear bamboo collected from the mountain according to the principle of using no raw materials and no poison of Chinese herbs is used for one month or more. Therefore, it can be said that natural drying is the technology of preservation method.

(C) Problems to be Solved by the Invention (a) Problems of Conventional Technology It is difficult to stabilize (preserve) chlorophyll in leaves by the conventional natural drying method, and the chemical structure of chlorophyll is ,heat,
Easily destroyed by air. Furthermore, we could not expect to extract chlorophyll in hot water.

(B) Technical Problem Therefore, the present invention preserves chlorophyll contained in fresh leaves of bear bamboo in a stable state for a long period of time, and preserves it so that it can be used for extraction of bear bamboo extract containing chlorophyll whenever necessary. Is what you are trying to do.

(B) Constitution Although the present invention is provided for the above object, the constitution will be described below.

(1) About means for solving problems.

Put an appropriate amount of water in a treatment layer having an appropriate volume, add sodium bicarbonate, sodium chloride and sodium carbonate into it and mix well to form a treatment liquid. Heat to 80 ° C or lower, and add an appropriate amount of fresh bear bamboo leaves into the heat treatment liquid.

It is needless to say that the treatment liquid may be a mixture of water and the above chemicals that has been melted in advance and placed in a treatment tank for heating.

Next, while maintaining the temperature of the treatment solution containing the raw leaves of bear bamboo, the bear bamboo is agitated in the treatment tank for an appropriate period of time to allow the treatment solution to penetrate into the bear bamboo.

Next, the bear bamboo leaves are pulled out from the treatment tank, the treatment liquid is drained, and this is completely dried by a dryer. In that case, 60% by weight of the initially used bear bamboo leaves can be obtained as dried bear bamboo leaves.

This dried bear bamboo leaf is put in a container having good air permeability and stored in a place having good air permeability and avoiding sunlight.

(2) About action The medicinal effect of bear bamboo extract has been studied for a long time,
Moreover, it has been used as a folk medicine or a Chinese medicine for various diseases for a long time.

That is, bear bamboo extract is a bear bamboo extract that destroys the cell membrane of bear bamboo leaves and extracts all components contained in the cells, and this bear bamboo extract contains polysaccharides, lignin, dietary fiber, vitamins. It is rich in various vitamins such as A, B ₁ , B ₂ , B ₆ , B ₁₂ , C ₁₂ , E and K, amino acids, minerals and other ingredients, which act synergistically and have medicinal effects. Is to demonstrate.

When chlorophyll (chlorophyll) extracted from bear bamboo leaves in its natural form enters the body, it exhibits a strong affinity for the cells of tissues in the body, and the lipids and proteins forming the cells Since they are bound and integrated, chlorophyll can sufficiently exert the action effect of the nucleus portion (electron transfer effect by the magnesium chelate).

After all, the main effect of chlorophyll is in the nucleus of the unique chemical structure containing Mg, that is, in the chelate part, but Mg bound to the chelate in the center of the molecular structure is for the preservation of bear bamboo or the extraction of bear bamboo extract. Since the chlorophyll in the natural state disappears as a result of a drying process (eg, light, heat, oxygen (air)) as a pre-treatment for the treatment, the natural chlorophyll disappears. It must be said that it is an extract extracted from bear bamboo shoots and the main effect of chlorophyll has disappeared.

Therefore, it is extremely difficult to collect chlorophyll in a natural state and use chlorophyll (chlorophyll) as a product having a molecular structure similar to that in a natural state.

Therefore, the present application intends to provide a technical means capable of preserving bear bamboo leaves for a long period of time without leaving chlorophyll having such a great effect as it is and without losing other various medicinal components.

Therefore, the effect of treating raw bear bamboo leaves with the above-mentioned treatment liquid is as follows. The treatment liquid is hot water at 70 ° C or higher and 80 ° C or lower.

The treatment liquid is weakly alkaline due to sodium bicarbonate.

 Sodium chloride is melted in the treatment liquid.

 The processing time is generally 10 to 15 minutes or less.

When raw bear bamboo shoot extract is added to the above treatment liquid,
As a method of Taman cooking, a method of boiling with a short time of boiling water is used as a method of boiling so as not to lose the green color of vegetables (referred to as Aoni). According to this method, chlorophyll is kept stable and the green color is Not lost Also in the present application, the principle of Aoni is used to keep the temperature above 70 ℃ and below 80 ℃ for a short time (10 to 15 minutes).
Min) When heat-treated, the chlorophyll of bear bamboo leaves is kept stable as green. The reason is that plants have enzymes everywhere such as leaves, stems and roots (distribution), and are deeply involved in decomposition and synthesis reactions, and the action of these enzymes is most active at 40 ° C to 50 ° C. , The effect diminishes when the temperature rises or falls, and it is said that at high temperatures above 80 ° C, the enzyme is destroyed and loses its action.

However, among the enzymes possessed by plants, phenylalanine ammolyase (PAL) is an enzyme that decomposes chlorophyll (chlorophyll) in the fall and synthesizes so-called autumn colored pigment (anthocyan), and chlorophyllase (enzyme).
Is an enzyme that decomposes chlorophyll to produce chlorophyll and phytol.

Therefore, inactivating the enzyme contained in these plants to decompose chlorophyll is an important requirement for retaining chlorophyll (chlorophyll).

Therefore, in the present invention, a means for inactivating without destroying these enzymes is adopted, and the temperature of the treatment liquid is 70 ° C. or higher and 80 ° C. or lower as the means, and the bear water is shortened with the hot water. I decided to heat-treat for 10 minutes to 15 minutes. In that case, the enzyme is inactivated.

On the other hand, since this heat treatment is at a temperature of 70 ° C to 80 ° C,
It has the effect of destroying and softening the fibrous tissue of bear bamboo leaves to some extent, and permeating sodium bicarbonate, sodium chloride and sodium carbonate into the tissue of bear bamboo leaves.

Next, the action of sodium bicarbonate, sodium carbonate and sodium chloride in the treatment liquid will be described.

Sodium bicarbonate, sodium chloride, and sodium carbonate are added as chemicals, but sodium bicarbonate and sodium carbonate make the treatment solution weakly alkaline. I mentioned earlier that chlorophyll decomposes to form a pigment called anthocyan, but this anthocyan is a water-soluble pigment that appears in plant leaves and flowers, and is an unstable substance that turns red when dissolved in water. It becomes even brighter red when acidified. However, since it has the property of exhibiting a blue color when it is weakly alkaline, it has the effect of brightening the green and turquoise colors of leaves and stabilizing the green color of chlorophyll.Sodium bicarbonate and sodium carbonate are added for this stabilization, and the solution Is a weak alkali.

In addition, sodium bicarbonate and sodium carbonate have mucolytic and fat-softening effects, and soften plant fibers, further soften the leaf cell tissue that has been somewhat softened by heat treatment, and allow the penetration of sodium bicarbonate and sodium carbonate. Help

Furthermore, sodium chloride has the effect of increasing the osmotic pressure of the treatment liquid.

That is, if the treatment liquid is water, the osmotic pressure is low, so that water is absorbed into the tissue, but by adding sodium chloride, on the contrary, the osmotic pressure of the treatment liquid increases, and It prevents the absorption of water and promotes the leaching of water from the tissue into the processing solution.

Next, the drying process will be described.

Drying is performed to prevent the generation of mold and the action of the enzyme during storage. It is clear that water is related to microbial growth and enzyme action, and that growth of bacteria is suppressed when the water content is 50% or less, and bacteria cannot be grown below 15%. It is well known. However, it is said that it is extremely effective to further reduce the water content of molds.

Therefore, most of the bacteria have been killed by the previous heat treatment and the enzyme has been inactivated. However, in order to improve the storage condition and to ensure quality over a long period of time, dry treatment is performed and the water content is reduced to zero.
Save closer to%.

(3) Example Next, an example will be described.

Put 448 (70%) of water in a treatment tank of 640 in volume, and then add 80 g of sodium bicarbonate, 80 g of sodium carbonate and 80 g of sodium chloride, stir and melt to obtain a treatment liquid.

It is needless to say that the processing liquid may be melted in advance in the above-mentioned amount ratio and placed in the processing tank.

Next, the treatment solution is sprayed with hot steam from a steam boiler to bring the temperature of the treatment solution to 70 ° C to about 80 ° C (below 80 ° C), and 15 kg to 20 kg of fresh bear bamboo leaves (the number of fresh leaves) is applied to the treatment solution. 10 to 14,000 sheets), and the temperature of the processing solution is maintained below 80 ℃ and below 70 ℃ by spraying steam.
Stir for minutes to 15 minutes. In such a case, enzymes such as phenylalanine ammolyase and chlorophyllase present in bear bamboo leaves can be inactivated by heat and the leaf cell tissue (plant fiber) can be softened.

Further, sodium bicarbonate and sodium carbonate soften the vegetable fiber, and sodium chloride enhances the permeation of the treatment liquid.

When the above heat treatment is completed, bear bamboo leaves are pulled out from the treatment tank, the treatment liquid is drained, and then placed in a dryer to be completely dried.

In that case, 60% of the initial weight (9 to 12 kg) of dried bear bamboo leaves can be obtained.

This dried bear bamboo leaf is cut as it is or appropriately cut and put in a well-ventilated container such as a hemp bag and stored in a well-ventilated place away from sunlight, and taken out when necessary to extract bear bamboo extract use.

(C) Effects of the Invention Next, effects of the present invention will be described.

By heat-treating bear bamboo leaves, the enzyme (phenylalanine ammolyase.chlorophyllase) contained in the leaves is inactivated, and the decomposition of chlorophyll (chlorophyll) by the enzyme is blocked, so that the red pigment of anthocyan Green chlorophyll is preserved because synthesis is prevented.

Further, since the treatment liquid is weakly alkaline, it stabilizes (does not oxidize) the green color (pigment) of chlorophyll and makes it fresh.

In addition, the fiber tissue of bear bamboo leaves is softened by the softening action of plant fibers by heat treatment and mucolytic dissolution of sodium bicarbonate and sodium carbonate and the fat softening action, so that the permeability of the treatment liquid (ingredient) is improved and the above-mentioned action effects are obtained. It has the effect of helping and facilitating the subsequent extraction of chlorophyll.

Next, sodium chloride increases the osmotic pressure of the treatment liquid into the bear bamboo leaf tissue, prevents the absorption of water into the tissue, and conversely promotes the leaching of water from the tissue into the treatment liquid, and the green color of the bear leaf It becomes darker. Storage in a completely dry and well-ventilated place has the effect of suppressing the growth of bacteria and mold and contributing to long-term storage.

By the way, no change was observed in the chlorophyll blue-green color even after storage for 5 years.

The extraction of chlorophyll was also good.
