Abstract

PURPOSE:Aqueous paste of crude drugs or herb medicines is irradiated with microwaves in the presence of vinegar to give sterilized seasoning paste keeping original smells of the herbs with high storage stability. CONSTITUTION:Spices, herb medicines such as pepper or clove are crushed to particles of 40-150 mesh and they are mixed with water into a paste. Then, the paste is combined with vinegar or wine vinegar so that the acetic acid concentration becomes 0.5-2%. The resultant paste is charged in a tightly closed system and irradiated with microwaves of 1,000-2,500MHz from the outside of the system.

Description

[Detailed description of the invention] <Industrial application field> The present invention relates to a novel sterile pasty seasoning.

In recent years, a wide variety of herbal medicines, such as koshiyo, clove, cinnamon bark, thyme, sage, and fennel, have been used in the preparation of various foods in ordinary households. These herbal medicines are used to impart their original and excellent aroma (or flavor, hereinafter simply referred to as aroma) to foods.

The present invention provides a sterilized product that is convenient for storage and specific use, retains the aroma inherent to herbal medicines, and can therefore easily and appropriately impart the excellent aroma inherent to herbal medicines to food during cooking. Regarding paste seasoning.

<Prior art and its problems> Traditionally, crude drugs used in the preparation of food in ordinary households are usually dried or ground products.

However, since the dried and crushed products are not such that the unit quantity traded for household use is used in its entirety at one time, the aroma components may be lost during the distribution stage or while being stored at home. The problem is that the original scent of herbal medicines is significantly lost (or damaged) due to natural ventilation and oxidative deterioration with the air. However, there are problems in that it is inconvenient to use, such as scattering during cooking.

<Problems to be Solved by the Invention and Means for Solving the Problems> The present invention solves conventional problems such as slanting.

Therefore, the present invention provides a sterile paste which is made by sterilizing an aqueous paste of crude drugs in a closed system in the presence of at least vinegar by irradiating microwaves from outside the closed system. Concerning seasonings.

In the present invention, the target herbal medicines are not particularly limited, such as koshiyo (black koshiyo, white koshiyo), clove, cinnamon bark, pei leaves, thyme, sage, fennel, etc.
These can be used alone or in combination.

First, an aqueous paste of the crude drug is obtained. The paste-like material in this case is a homogeneous mixture that has a paste-like appearance in order to make the subsequent sterilization by microwave irradiation effective. Therefore, the paste can be obtained by heating dry-crushed or pulverized crude drugs in an aqueous system, or wet-crushed or pulverized crude drugs mixed in an aqueous system, for example, in a closed container. It will be done. The crushing or pulverization of crude drugs may be about 40 to 150 meshes, and the concentration in the aqueous system varies depending on the type of crude drug, for example, the amount of starch contained in the crude drug, but it is generally about 20 to 30 mesh by weight. do it.

Then, when or after obtaining the paste-like material, at least vinegar is allowed to coexist by stirring, mixing, or the like. In this case, sugars, salts, etc. may be similarly allowed to coexist as appropriate. There are no particular restrictions on the vinegar used here; for example, commercially available wine vinegar can be used. The vinegar makes the subsequent sterilization by microwave irradiation more effective, and its own flavor blends well with the herbal medicine, which together make the final sterile paste seasoning suitable for the purpose. shall be taken as a thing. The amount used will vary depending on the type of herbal medicine, but it should generally be such that the concentration of acetic acid in the paste is about 0.5 to 2%. Therefore, especially when using vinegar produced by static fermentation with an acetic acid concentration of about 4%, and even when using vinegar produced by aerated fermentation with an acetic acid concentration of more than 10%, it is usually necessary to consider the number of steps involved. , it is advisable to coexist the vinegar with a suitable amount of water so as to form an aqueous system as described above.

Next, the above paste-like material is charged into a closed system in the presence of at least vinegar. The closed system in this case may be a container for batch processing (preferably equipped with a stirrer or a mixer) or a pipe for continuous processing. The paste-like material is sequentially press-fitted into a pipe equipped with a regulating valve. There are no particular restrictions on the materials for these sealed systems as long as they are materials that effectively transmit microwaves, have a certain degree of heat and pressure resistance, and are insoluble in the paste. For example, ceramics and Teflon may be used. Can be used. Then, the paste-like material charged into the closed system is sterilized by irradiating microwaves from outside the closed system. The microwave in this case is a general 1000~2500MH
A high frequency of about Z is sufficient, and its output etc. are determined depending on the relative relationship with the paste-like material to be sterilized, but 10 Kw is sufficient on a trial basis. Since the paste inside the closed system is sterilized by irradiating microwaves from outside the closed system, the inside of the closed system is put into a pressurized and overheated state at least during the microwave irradiation. This is largely influenced by the type of herbal medicine in the paste and its bacterial properties, but in normal cases, the paste is prepared in a closed system at a temperature of about 110 to 120°C for about 1 to 3 minutes.
The paste-like material is completely sterilized under pressure conditions of 1 to 3 kq/atl.

In this way, the sterile pasty seasoning according to the present invention is obtained, but the specific means and form before and after sterilization of the final product may be according to well-known conventional methods. For example, the product sterilized as described above is cooled as soon as possible. In batch processing, the container may be put into water after the microwave irradiation is stopped, or in continuous processing, a series of tubes is provided with a microwave irradiation section followed by a cooling section. The cooling section may be externally water cooled. The cooled product is then aseptically filled into tubes, bags, etc. to produce the final product. For example, before sterilizing as described above, a paste-like material is filled into a bag or a bag-like material, and then sterilized by irradiation with microwaves and then cooled to produce a final product.

The important point of the present invention is that the aqueous paste of herbal medicines is sterilized from the outside by microwaves in a closed system in the coexistence of at least vinegar. Herbal medicines are
Because of its origin, it naturally contains an extremely large number of viable bacteria, and there are also many heat-resistant bacteria. Therefore, in order to obtain a sterile pasty seasoning like the one of the present invention, a correspondingly severe sterilization treatment is essential. There have long been various methods for sterilizing crude drugs, such as simple indirect heat sterilization (using electricity or steam), direct heat sterilization with superheated steam, radiation sterilization, and even a combination of these.

However, in such simple indirect heat sterilization or direct heat sterilization using superheated steam, complete sterilization takes a relatively long time and the original aroma of crude drugs is significantly lost. Further, in direct heat sterilization using superheated steam, it is actually extremely difficult to prepare the sterilized product into a sterile paste seasoning as in the present invention. Furthermore, food hygiene problems cannot be avoided with radiation sterilization. The reason why the present invention sterilizes herbal medicine pastes from the outside using microwaves in a closed system, and at least vinegar is coexisting during this sterilization, is that the final sterilization of a suitable flavor (lance) is achieved. The purpose is to obtain a paste-like seasoning and to make maximum use of the excellent aroma inherent in crude drugs in the sterile paste-like seasoning.

<Functions and Effects of the Invention> As explained above, the present invention relates to a sterile paste seasoning, which by its nature is filled into cheeses, bags, etc. Therefore, during the distribution stage or while being stored at home, there is almost no diffusion of fragrance components or oxidative deterioration with the air, and the original fragrance is retained for a long period of time. Moreover, because of its form, it is convenient to store at home, and it is convenient to use because it does not scatter during cooking. In particular, the sterile paste seasoning according to the present invention has the excellent aroma inherent to crude drugs and has a suitable flavor balance. That is, as mentioned above, in the present invention, microwaves are irradiated to an aqueous paste of crude drugs that has a paste-like appearance in the presence of vinegar.
In the paste, each crushed or ground herbal medicine particle is uniformly impregnated with moisture, and this moisture acts as a receptor for microwaves, so each particle is rapidly absorbed. is internally heated. Furthermore, since such internal heating occurs in a closed system in the presence of vinegar, the paste-like material is completely sterilized in an extremely short period of time under pressure and superheat conditions.

In the sterilization of crude drugs that have a large number of viable bacteria and many heat-resistant bacteria, the sterilization effect that meets the purpose of the present invention can be obtained by removing boiling water or superheated steam from the outer surface of each particle of crushed or ground crude drug particles. This cannot be achieved by the conventional means of bringing the two into contact with each other and heating them externally.

<Examples> Hereinafter, examples will be given to make the structure and effects of the present invention more specific.

Add and mix commercially available wine vinegar with an acetic acid concentration of 4.6% and water to the herbal medicines so that the total acetic acid concentration is 0.7% for black koshiyo and 1.0% for mixed herbal medicines. The mixture was heated in a closed container for a short time to reach a temperature of 80° C. to form a paste. Next, this is continuously press-fitted into a Teflon tube with an inner diameter of 20 mm while irradiating microwaves from outside the tube, and the paste-like mixture is held in the tube at a predetermined temperature for a predetermined period of time. The tube was cooled with water to obtain a sterile paste seasoning (4 categories in total). The sterilization data is shown in Table 1, and the gas chromatography analysis data of the fragrance components is shown in Table 2. The obtained sterile paste seasonings (4 categories in total) were all inspected by three carefully selected inspectors.
As a result of a sensory test in which 0 people compared the paste with the corresponding paste before sterilization, the scent was evaluated to be exactly the same. The herbal medicines used here were all dry-pulverized to 40 to 60 mesh, and the representative examples with a large number of viable bacteria, Kurokoshiyo, were produced in Malaysia, cloves were produced in Sanjibar, and cinnamon and fennel were produced in China. Leaves and sage are from Turkey, and thyme is from France, and the mixed herbal medicines in the table are equivalent combinations of the above herbal medicines.

Table 1 Note: The number of viable bacteria was measured after culturing on a standard agar medium for 48 hours (cells/g).

Table 2 Note: The aroma components used as indicators are: A is β-caryophyllene, B is
is eugenol, C is cinnamaldehyde D carinalol, E is thymol, F is d-camphor, G is anethole, and the total component is the sum of all peaks displayed on the gas chromatograph chart including these. All numerical values in the table are relative values when the area of the corresponding peak displayed on the gas chromatograph chart before killing is set as 100. Gas chromatography analysis was carried out as follows: A sample was extracted for 92 hours using a Nickerson-Rickens steam distillation continuous extraction apparatus, and the resulting extracted ether solution was subjected to gas chromatography. The gas chromatograph used at this time had a glass column of 3 m diameter x 3 m, a packing material of Salmon 1500 (manufactured by Shinso Kako Co., Ltd.), a carrier gas of nitrogen gas, a detector of FID, and a temperature of 240°C.
