In the early 1970s, Eskimos, whose only fish and seafood were produced by Bang and Dyerberg, had a very low incidence of adult diseases such as atherosclerosis, myocardial infarction, high blood pressure, angina pectoris, stroke and diabetes. Since reporting the facts, numerous studies have been conducted on the biological activity of marine organisms. Algae is a generic term for silver plants that grow in seawater, and is classified into green algae, brown algae, and red algae. A total of about 400 species of algae grow wild in Korea's surrounding waters.

Many of them are edible, but their value as stocks is small. The reason is that most carbohydrates of algae are non-digestible polysaccharides, which are relatively stable to acids and alkalis and are difficult to decompose by special bacterial enzymes, and their digestibility is less than one third compared to that of general land plants. . However, the food value of algae is rich in its unique flavor, various minerals, vitamins, trace elements, special amino acids and dietary fiber, and in addition, it is richer in carbohydrates and proteins than other plants, so it has been used for food, food, medicine In addition, it has been widely used as livestock feed and fertilizer.

Algae is an alkaline food containing abundant minerals such as calcium, magnesium, iron, zinc, iodine and selenium, active amino acids, vitamins, and dietary fiber, which induces constitution weakly and helps strengthen disease resistance or resilience. Gives.

In addition to minerals and vitamins, seaweed contains various functional ingredients such as taurine, polyunsaturated fatty acids, alginic acid, laminarin, and dietary fiber that may exhibit physiological activity when consumed by higher animals. Although it contains abundant minerals, vitamins, and bioactive substances, seaweeds are very vulnerable to biological conditions, and although processing is essential, they do not utilize resources efficiently due to lack of current processing level or development of processing technology. I can't do it. However, it is not easy to manufacture processed foods using only seaweeds, so it is difficult to find processed foods prepared using seaweeds as the main raw material.

Therefore, a new seaweed processing method that can maximize the pharmacological effect by fully expressing various pharmacological possibilities using only seaweed is required. In addition, when only natural seaweed is used, the necessity of developing a method capable of fully utilizing the shelf life of the processed seaweed has emerged.

In another aspect, the present invention provides a aging seaweed composition, a method of using the aging seaweed composition as a natural preservative, and a natural preservative composition comprising the aging seaweed composition, characterized in that it is produced by the method for producing the aging seaweed composition.

It will be described in more detail below.

The process of producing the aged seaweed composition of the present invention is characterized by undergoing a preliminary aging step, a first aging step in a closed space, a second aging step in a bath apparatus and a heat drying step.

Seaweed used in the aged seaweed composition of the present invention is mainly seaweed, seaweed, seaweed, green sea and the like can also be used. It is most preferred to use a mixture of the seaweeds in order to prepare the aged seaweed composition, but kelp or seaweed showed good efficacy required by the present invention even when used alone.

The composition of the seaweed for preparing the aged seaweed composition is 1) 100 parts by weight of seaweed, a combination consisting only of seaweed and seaweed consisting of 20 to 500 parts by weight of seaweed, 2) 100 parts by weight of kelp, 1) parts by weight to less than 40 parts by weight, 1 part by weight to less than 60 parts by weight of seaweed, a combination consisting of laver and seaweed, 3) about 100 parts by weight of seaweed, 1 to 40 parts by weight of laver, 4) seaweed 1 to 40 parts by weight and seaweed 1 to 40 parts by weight and seaweed 1 to 40 parts by weight and seaweed 1 to 60 parts by weight It is preferable that it is any one selected from the combination which consists of seaweed, seaweed, seaweed, and seaweed which consist of a part.

It is preferable that the seaweed is naturally dried in the sea breeze, and that the seaweed is dried by hot air.

The preliminary aging step of the present invention is characterized in that it comprises a step of washing the seaweed with water, and then putting the seaweed in water at a temperature of 2 ℃ to 22 ℃, for 1 month to 6 months low temperature aging. If the pre-aging temperature is less than 2 ℃ aging does not occur well, if it exceeds 22 ℃ aging occurs excessively, and also the preservation effect of the final aging seaweed composition is reduced. If the aging period is less than 1 month, the aging is not enough, if more than 6 months does not see the excess aging effect over time, there is also a problem that the storage cost increases. The preliminary aging temperature is more preferably from 5 ° C to 10 ° C, and more preferably from 2 months to 4 months. The preliminary aging step is an optional step that may be omitted.

When washing the seaweed with water, it is desirable not to wash too much so that the salt remaining in the seaweed is completely removed. Salt groups remaining in natural seaweeds contain various mineral components, which can increase the commercialization of the aged seaweed composition. In addition, when the aged algae composition is prepared with a sea salt with a certain amount of salt, the preservative effect is better than when the aged algae composition is prepared with the sea salt in which the salt is completely removed. You need to keep salty.

The first step of aging the seaweed of the present invention is to wash at least one or more seaweeds, including kelp naturally dried in the sea breeze, and then to keep the seaweed in a closed space for 15 to 90 days in a temperature of 50 ℃ to 85 ℃ It is characterized by primary aging of the seaweed by arrangement.

The primary aging temperature is preferably 50 ° C to 85 ° C, more preferably 60 ° C to 80 ° C, and most preferably 65 ° C to 75 ° C. If the fermentation temperature is less than 50 ℃ fermentation hardly occurs or the fermentation is insignificant, there is little conversion to a high pharmacological effect of the existing seaweed components, there is a problem that the pharmacological and antiseptic effect of the final aged seaweed composition is insignificant, the maturation temperature 85 ℃ If it exceeds the fermentation rate is too fast there is a problem that is too mature.

The first aging time is preferably 15 to 90 days, more preferably 20 to 60 days, most preferably 25 to 35 days. If the aging time is less than 15 days, there is a problem that the taste of the seaweed composition is inferior due to insufficient fermentation, and if more than 90 days, decay is likely to occur, there is a lot of smell and the seaweed is too retired.

The primary aging is preferably carried out in a closed space (chamber, chamber) through which little air passes. It is preferable to arrange the seaweed in a layered layer in the enclosed space, and then to mature the seaweed in such a manner that the seaweed is heated by a heating wire so that temperature control is easy. In this case, the control of the humidity is important, the humidity is preferably maintained at 80% to 99%, more preferably at 90% to 95%. Humidity can be controlled by sprinkling water.

The algae primary aging composition prepared by primary aging of the pre-aged seaweed during the time at the temperature at the above ratio is excellent in sweet and sour taste or taste.

The second step of aging seaweed of the present invention is the second step of aging seaweed secondary aging for 15 to 60 days at a temperature of 55 ℃ to 95 ℃ using a bath apparatus comprising at least one cooling tower portion of the composition of the first aging step seaweed 2 A tea ripening composition is prepared.

1 to 3 show one embodiment of the bath apparatus of the present invention. Hereinafter, a description will be given with reference to FIGS. 1 to 3.

The bath apparatus includes a bath unit 200 for heating and bathing the seaweed secondary composition, and a heat source 100 for supplying heat to the bath unit opposite to the cooling tower units 300, 400, and 500 of the bath unit. ), The bath 200 and the cooling tower 300, 400, 500 has a structure in which the inside thereof is connected by a connection, the average cross-section of the connection (250a, 250b) is It is preferred that the average cross section is smaller than the average cross section of the cooling section.

The cooling tower unit is more preferably composed of three cooling towers (300, 400, 500) different from each other, the temperature of the three cooling towers different from each other the temperature of the primary cooling tower unit 300 closest to the bath portion 55 It is preferable to maintain the temperature of the secondary cooling tower unit 400 to 30 ℃ to 70 ℃, and to maintain the farthest third cooling tower unit 500 at 15 ℃ to 45 ℃, maintained at ℃ to 95 ℃.

Each of the cooling towers different from each other has a structure in which the inside thereof is connected by a connecting portion, and the average cross section of the connecting portion is smaller than the average cross section of each cooling tower portion.

As a method of cooling the cooling tower portion, ordinary cooling means can be used, but air cooling is preferred in the practice of the present invention. The cooling method of the cooling tower unit 300, 400, 500 by the fan 700 is more preferable. 3 illustrates an embodiment of a cooling method of the present invention for cooling the cooling tower unit with a fan 700.

In particular, while maintaining the temperature of the bath 100 is 55 ℃ to 95 ℃ is the first cooling tower 300 above the bath 100, the second cooling tower 400 and the first in order thereon When the cooling tower unit 500 is present, a method of cooling the cooling tower units 300, 400, and 500 with the fan centered on the second cooling tower unit 400 is more preferable.

In particular, there is a connection between the bath 200 and the cooling tower 300, 400, 500 and between each cooling tower, the average cross-section of the connection (250a, 250b) is smaller than the average cross-section of the bath and cooling tower portion. In other words, that is, when each connection portion is in a constricted shape, each cooling tower portion is cooled with a more distinct temperature difference.

When the three cooling towers, the temperature of the primary cooling tower 300 is preferably maintained at a temperature lower than the temperature of the bath 200, the secondary cooling unit 400 is 30 ℃ to 70 ℃ It is good to keep as. If it is out of this temperature range, there is a problem that the taste is poor. The third cooling tower unit 500 is preferably maintained at a low temperature, and more preferably maintained at about 15 ° C to 40 ° C. If the temperature of the third cooling tower 500 is less than 15 ℃ energy consumption is a big problem, if 40 ℃ there is a problem that does not catch all the volatile components.

The temperature of the bath 200 is preferably maintained at 55 ° C to 95 ° C, more preferably 60 ° C to 75 ° C. When the temperature of the bath 200 is less than 55 ° C., the fishy taste of seaweeds including kelp may be severe (particularly, when it is less than 45 ° C., the fishy smell may be severe), and when it exceeds 95 ° C., the sweetness of seaweed including kelp may be increased. Not only does the taste disappear, but there is a problem that the loss of energy used to cool the cooling towers 300, 400, and 500 located on the bath 200 is too large.

The time for hot water in the bath 200 is preferably 15 days to 60 days, more preferably 20 to 40 days, and most preferably 25 to 35 days. When the bath time is less than 15 days, there is a problem that the human affinity of the seaweed aging composition is lowered and the antiseptic effect is weakened, and when the bath time exceeds 60 days, the energy entering the bath is increased to increase the production cost, rather, the antiseptic effect. Has the problem of falling.

If there is one or two cooling towers, it is preferable to maintain the temperature of the cooling tower having the lowest temperature at 15 ° C to 40 ° C.

The cooling tower unit 300, 400, 500 is a great help in the function of increasing the pharmacological and antiseptic effect by catching the vapor in the form of steam coming from the hot water bath while also catching the volatile components.

The humidity of the bath 200 is preferably maintained at 90% or more, more preferably at 95%.

Subsequently, the seaweed secondary aging composition is taken out of the bath apparatus and dried. The drying step is to heat the seaweed secondary ripening composition for 30 to 80 hours while heating with a heating device maintaining a temperature of 70 ℃ to 100 ℃ to evaporate the water contained in the liquid component of the seaweed secondary ripening composition In a way. The drying is preferably heated for 48 to 72 hours while heating the seaweed secondary aging composition with a heating device maintaining a temperature of 90 ℃ to 95 ℃. If the temperature of the heating device is less than 70 ℃ evaporation of water through the heating is not easy, the time is excessively added to the completion of the process, if the temperature exceeds 100 ℃ may be too quickly evaporated to dry excessively. If the heating time is less than 30 hours, the level evaporation is not easy. If the heating time is more than 80 hours, there is a possibility that the water is excessively evaporated and overdried. The dried seaweed secondary ripening composition is cooled under atmospheric pressure.

When preparing the seaweed ripening composition of the present invention, the first step of aging seaweed and the second step of aging seaweed may be repeated two or more times within five times.

The seaweed ripening composition treated 1 to 5 times may be dried to prepare a powder.

In addition, the seaweed aging composition may also be used as a natural preservative. The antiseptic effect was identified as an antimicrobial activity test consisting primarily of a hypotonic test and an observation of an increase in E. coli after inoculation with E. coli. Detailed descriptions thereof are given in the following storage test and antiseptic test, and the results are shown in Tables 2 and 3 below.
