How to extract red pepper component liquid from red pepper

The present invention relates to a method for extracting red pepper component liquid from red pepper.

In general, red pepper powder varies depending on the cooking method, but it is only a few tenths of the actual content to feel the color or spicy taste of red pepper compared to the actual amount used. This is because no matter how finely ground the red pepper powder is, the color and the spicy taste contained in the particles are not eluted during the intake process.

The present invention is to provide a concentrated solution extracted pepper component solution in view of these problems.

In the present invention, the pepper component solution is composed of water-soluble and oil-soluble components except for the cellulose wood part and fine particles of red pepper (including the epidermis and seeds of the red pepper), which are red pepper components present in the aqueous solution or suspension solution in the aqueous solution. Say solution. Therefore, when the red pepper component of the present invention is used as a seasoning, its taste and aroma are exactly the same as natural black pepper, but its spicy taste reaches several times.

In addition, red pepper powder may be contaminated by mold or bacteria during the storage or use of red pepper powder during drying, storage and grinding of raw red pepper, which is unsanitary, but the present invention is hygienic and mass-produced due to the specificity of the manufacturing method (extraction method). Cheap supply is possible.

In the present invention, the red pepper component solution is prepared in the form of an oil solution or a water suspension, and is used as a seasoning, but it can also be used as a natural powder by making it into fine powder again. In addition, the pepper component liquid of the present invention may be supplied in a concentrated state or may be prepared and supplied in a diluted state.

The red pepper component liquid of the present invention is prepared by applying an organic solvent extraction method, and specifically, after grinding natural red pepper, the red pepper component is separated by extraction with an organic solvent or a mixed solvent at high temperature and high pressure, if necessary, and is purified again. It is a method of manufacturing a component liquid.

Separating only the main components of red pepper from natural pepper and using it as an edible seasoning has not been disclosed until now, but it is only used to produce red pepper seed oil by roasting red pepper seeds and milking them in a milking machine.

In the case of foreign countries, there is no product from which food is extracted, but there is no known method for preparing a pepper component liquid according to the present invention containing vitamins, proteins, and the like obtained by extracting main components from natural pepper.

In addition, as a method of extracting food, a method of preparing a mixed extract of garginine and locust bean gum of Korean Patent Publication No. 83-1706 and a method of preparing a Yulmu beverage solution of No. 83-2005 are disclosed, but all of them are different from the method of the present invention. Not only that, but the target food to be extracted is different.

As a method for separating and purifying the active ingredient of red pepper, large leaching method (including steam distillation method) and compression method may be considered once. And since the separated effective ingredient contains various impurities, it is necessary to refine | purify. As a purification method, it can refine | purify by distillation, steam stripping, redissolution, filtration, etc.

Among the possible methods described above, the crimping method may be completed as in the case of red pepper seed, but compared with the crimping method, the method of the present invention firstly has a high yield and thus a large amount of red pepper extract, and second, various kinds of ingredients. There is an advantage that can be collected as an active ingredient.

When explaining the pepper component liquid production method and apparatus of the present invention in detail.

The natural red pepper is collected and then put into raw material processing process to remove foreign substances, screening and removing bad red pepper, and then adjust the moisture to be suitable for grinding in the drying process. . The grinding process makes the red pepper to fine powder before and after about 60 samples. The red pepper powder is pulverized in the extraction process, which is the center of the manufacturing method, the red pepper component is extracted, and then the extract is prepared through the solvent removal step, concentration step, drying step, purification step and the like. This will be described again by process.

Raw material processing process: The supplied red pepper removes mineral substances such as stones and sand as foreign substances, and also removes poor quality red peppers such as poor quality and immature. Then remove the stem and complete the pepper sorting. The above sorting operation can be carried out with the naked eye and manually or semi-automatically.

Drying process: Selected peppers are adjusted to 7 to 17% of moisture content to facilitate grinding, and it is preferable to dry them as naturally as possible, but in some cases industrial (artificial) hot air drying, infrared drying, Indirect hot plate drying can be used. However, natural drying is easy to extract in the extraction process, which is the next process, it is better to dry as naturally as possible. In addition, when performing industrial hot air drying, it is necessary to try to make the drying conditions similar to the natural conditions.

Grinding process: The dried pepper is ground to 40 to 80 mesh in the grinding process. Pepper milling uses a roller mill and other conventional mills may also be used. The grinding method can be arranged in series with several grinders in series and can be used to grind the size of the pepper in stages with a single grinder. The grinding temperature is carried out at room temperature and does not need to be heated or cooled in particular.

Extraction process: Crushed red pepper is extracted using an organic mixed solvent in the extraction process. The extraction method according to the present invention is not pure solution extraction, but close to the colloidal solution, and therefore, a considerable amount of pepper powder is dispersed. Firstly, a large amount of solvent is required, and since the extraction amount must be extracted in a colloidal form, pepper or pepper The components are extracted at a high temperature as far as possible without causing pyrolysis, and in some cases, may be carried out under pressure. In addition, since the components of the extract vary depending on the extraction temperature and pressure, the extraction process conditions have a great influence on the ratio of each component of the extract as well as the extraction amount.

As the extraction solvent, it is preferable to use 2 to 4 times of the ground red pepper standard, and the extraction temperature is suitable to be in the range of 50 to 80 ° C. Extraction times are generally temperature dependent but range from 1 hour to 10 hours. The extraction device may be a batch type extraction tube, or may be continuously operated as a continuous extraction machine. As the solvent, alcohols, hexane, ether, water or a mixture of one or more thereof are used, and inexpensive solvents are used for the price. The amount of solvent used is extracted by batching at a ratio of 2 to 4 weight times of red pepper powder.

The solvent type is selected in consideration of the solvent dissolving ability to selectively dissolve only the active ingredient of red pepper. For example, ethyl alcohol extracts more carbohydrate-based components, while hexane extracts phospholipids, proteins, pigments, and flavors. Ether preferentially extracts fat. The recovered solvent is used for recycle.

Solid-liquid separation hole: The solid-liquid separation process is performed by a conventional stationary separation, a centrifugal separation method, a conventional filtration method, or a combination of these methods. As a preferred solid-liquid separator, a rotary vacuum filter is advantageous.

Concentration and solvent recovery process: The filtrate through the filter is separated from the solvent in the concentration process. That is, the filtrate is heated in concentration for solvent distillation to evaporate the solvent and to give a concentrate as a residue. The evaporated solvent is condensed in the condenser and, if necessary, separated from the condensed condensate and separator at the same time and then used repeatedly. The product, concentrated to residue, contains a small amount of solvent, but can be removed by blowing water vapor directly to remove it, or completely eliminating the solvent by using a vacuum system.

Refining Process: If refining is necessary, refine the red pepper solution using the refining method. In the present invention, conventional purification methods, that is, methods such as distillation, filtration and solvent extraction may be used again.

Finishing process: The prepared red pepper solution is stored in a storage tank and then packaged as a commodity.

되어서 특정 목적과 향기를 가지는 고추 추출물을 만들 수 있다.As another method of the present invention, it may be extracted for each active ingredient of red pepper by a solvent fractionation method. In this case, perfal, liquid propane and various alcohols are used as the solvent. As a method of operation, a solvent or a mixture of solvents with selective extraction ability is prepared, extracted with sufficient contact with red pepper powder, left to stand in equilibrium, and then allowed to settle in the upper and lower layers, respectively. After separating and obtaining each of the layers (Roffinate) filled with red pepper powder, it is possible to obtain each of the red pepper components having different mutual properties by removing the solvent therefrom. Each chili ingredient thus obtained is prepared again as needed.

It can be used to make pepper extracts with a specific purpose and aroma.

EXAMPLE

From the mature natural cultivated peppers, foreign substances and bad peppers are removed, and the dried and red peppers, which are 9% moisture-selected and dried peppers, are pulverized with laboratory mortar, and 95% pass through 60 mesh.

The pulverized pepper was added to a 1 Kl Soxhlet extractor, and 250 l of a mixed solvent (methanol and hexane ratio of 5: 1) was added, followed by extraction for 4 hours while maintaining the extraction temperature at about 70 ° C. After the extraction is complete, the Soxhlet flask is separated, and then the extract is separated, followed by solid-liquid separation using 30 micron filter paper. After the filtrate was distilled again under vacuum to completely remove the solvent, the red pepper component solution was concentrated by continuing vacuum distillation at a temperature of 50-60 ° C. The concentrated red pepper solution was found to be excellent in fragrance and spicy taste. The following is an example of comparing the red pepper powder and the red pepper component liquid of the present invention.

Yes :

Mix 100g boiled bean sprouts with 5g high quality red pepper powder, mix them separately, and mix equal amount of boiled bean sprouts with red pepper component liquid extracted from 5g of homogeneous red pepper powder. It was confirmed that the taste of radish was five times as hot as the taste of radish mixed with red pepper powder.

These results confirm that the hot and hot color extract from red pepper powder did not elute more than 50% of the hot components even after 5 hours of drinking water boiling water extraction. In addition, by confirming that more than 60% of the spicy content is not eluted, it can be proved that the spicy taste felt by ingesting red pepper powder in an unspoiled state is extremely weak.

Since the red pepper component concentrate of the present invention is about 10% of the red pepper amount, eventually the red pepper storage amount can be reduced by 1/10, and in actual usage, it has the same sensory value as 1/10 of the red pepper amount. Waste). In other words, when pepper consumption is 50 tons / day, it is 5 tons / day of component liquid and 50 tons / day × 1/10 = 5 tons / day, which is extracted from 5 tons / day. Since it is the same as the red pepper component solution, it can be concluded that 45 tons of red pepper can be saved. Therefore, if it is possible to replace red pepper powder with ingredient extract at the national level, it will have the effect of reducing red pepper powder usage by at least 50%.
