Therefore, since the above elements are provided, omega-3, 6, and 9 ingredients Essential Fatty Acids of hemp oil [Oil extracted from raw hemp seed at 40° C. or lower by cold pressed technique without roasting] 120 may be added to the laver. In this way, health-oriented functionality that plays a key role in maintaining and activating the body's function, such as improving heart and cardiovascular function, can be reinforced. In particular, hemp oil 120 includes minerals such as calcium, iron, magnesium, manganese, phosphorus, potassium, zinc and vitamins B1, B2, B3, B6, D and E, and phytosterol of hemp oil 120 can reduce total serum cholesterol by an average of 10% and reduce bad LDL cholesterol by an average of 13%. Further, hemp oil 120 includes 9 essential amino acids and 18 amino acids, GLA (γ-linolenic acid), vitamins, minerals and dietary fibre. Aarginine, which helps fat burning and vasodilation, is also included four times as much as eel and 15 times as much as salmon, and many degenerative diseases due to aging can be prevented by taking the seasoned laver of the present invention. Further, hemp oil 120 has been known to have anti-cancer and antioxidant properties, and is rich in tocopherol, an antioxidant known to be effective in arteriosclerosis and phytol, as well as in Alzheimer's. Therefore, the seasoned laver of the present invention can play a sufficient role as a functional food which can have nutritional significance and physiological effects in favour of diseases and prevention.


In addition, the seasoned laver 100 according to an embodiment of the present invention, as shown in FIGS. 1 and 2, may further include an additive 131 added to the laver 110 to which the hemp oil 120 is applied, and dry flake 132. The additive 131 may include salt, and the dry flake 131 may include dried anchovy, dried shrimp, and dried vegetables. Thus, there is a unique savour and flavour, and the dry flakes 132 such as dried anchovy, dried shrimp, dried vegetables, etc. can enhance the taste and nutrition, and the destruction of nutrients can be minimized.


Hereinafter, referring to FIG. 1 and FIG. 2 continuously, a manufacturing method of the seasoned laver 100 according to another embodiment of the present invention will be described.


First, prepare dry raw laver S110.


Specifically, as shown in FIG. 3, the process of preparing dry raw laver S110 is: cutting raw material of the gathered laver into a set size S111, washing the raw material of the cutted laver to manufacture the raw laver S112, dehydrating the washed raw laver to dry raw laver S113.


More specifically, the preparation process S110 of the dry raw laver prepares the dry raw laver by using the raw material of laver. Generally, raw material of laver is produced from October to April every year and can be easily changed after harvesting, so it is usually processed as dry raw laver. The raw material of laver is red when it changes, and in this state, the pigment protein contained in a large amount of raw material of laver is lost and is not available.


After harvesting the raw material of the laver, dry raw laver in a dried form can be produced by natural drying or the like. For example, after harvesting raw material of laver, the raw material of laver is washed and dehydrated in purified salt water having a salinity of 5 to 7% and a temperature of 40° C. to 45° C., and dried for 20 to 40 hours in the shade of a temperature of 15° C. to 20° C., thereby producing dry raw laver.


In particular, in the present invention by washing the raw material of the laver using purified salt water having the above-described salinity, fine impurities that may remain inside the raw material of the laver by osmotic action can be easily discharged to the outside. Meanwhile, dry raw laver, manufactured in the preparation process S110 of dry raw laver, means a plate-type laver, which is manufactured after washing, dehydrating, and washing the raw material of laver, and then placed in a booboo blind with a certain thickness and width, and then through the drying process.


Then, dring dry raw laver S120.


Specifically, a drying process S120 is a process of manufacturing a dry raw laver by removing the moisture present in the dry raw laver. In the drying process S120, by using an infrared ray or a heater to remove the moisture present in the dry raw laver, it is possible to manufacture dry raw laver.


In particular, in the drying process S120 by drying the dry raw laver in a temperature range of 210° C. to 230° C., it is possible to remove the moisture present in the dry raw laver. As a result of the experiment, it was confirmed that the moisture inside the dry raw laver was not sufficiently removed when drying dry raw laver was performed in the drying process S120 below 210° C., and when drying raw laver was performed exceeding 230° C., it was confirmed that the surface of the dry raw laver was deformed by sudden excessive heat. Therefore, the drying process S120 is preferably carried out in the first in a temperature range of 210° C. to 230° C.


Thereafter, a first roasting S130.


Specifically, the first roasting process S130 is a process of manufacturing roasted laver by adding a heat source to the dry raw laver and roasting. The first roasting process S130 can manufacture the roasted laver by heating the drying raw laver in a temperature range of 250° C. to 280° C. By passing through the first roasting process S1300, the roasted laver has a colour changed to blue-green, and moisture remaining in the drying raw laver can be removed.


In particular, in the first roasting process S130, the dried raw laver can be roasted by heating the dry raw laver that is not seasoned to a temperature range of 250° C. to 280° C. As a result of the experiment, it was confirmed that the dry raw laver was not roasted sufficiently when the roasting of the dry raw laver was performed at the first roasting process S130 below 250° C., and when the roasting was performed exceeding 280° C., the dry raw laver was burned by sudden excessive heat. Therefore, the first roasting process S130 is preferably carried out in a temperature range of 250° C. to 280° C.


Then, apply the hemp oil S140.


Specifically, the applying process S140 of the hemp oil is a process of manufacturing seasoned laver by applying the hemp oil to the roasted laver. In the applying process of the hemp oil S140, by applying the hemp oil to the roasted laver, it is possible to enhance the flavour of the seasoned laver to be manufactured.


Here, the raw hemp seed oil extracted by cold pressing is used as the hemp oil without roasting the raw hemp seed. For reference, the hemp seed oil is replaced with at least one vegetable oil selected from the group consisting of sesame oil, Perilla oil, Schizandra, olive oil, soybean oil, corn seed oil, corn oil, grape seed oil, sunflower seed oil, canola oil, safflower seed oil and cottonseed oil used as the existing oil.


By applying hemp oil to the roasted laver, it is possible to enhance the useful ingredients of the hemp oil and the flavour of the seasoned laver. As the temperature for expressing oil is extracted below 40° C. by cold press technique, useful ingredients in the hemp oil can be protected.


Thereafter, additives and the like are added for additional seasoning S150.


Specifically, the adding process S150 is a process of adding, mixing and seasoning the additives containing salt and the dry flakes including dried anchovies, dried shrimp and dried vegetables to the roasted laver applied with hemp oil. In the adding process S150, hemp seed powder may be further added together with the dry flake.


For example, in the addition process S150, when the hemp oil is applied roasted laver, it is 100% by weight, by adding 0.5% to 2% by weight of salt, the roasted laver can be seasoned, and by adding 1% to 5% by weight of dried flake including dried anchovies, dried shrimp, and dried vegetables, the taste and nutrition can be enhanced to increase consumer preference. By adding more hemp seed powder to the roasted laver, the taste and nutrients can be enhanced to increase consumer preference. Further, in the present invention, salt from deep sea water rich in minerals may be used as the salt used in the adding process S150.


Meanwhile, in the adding process S150, an additive including salt and dry flakes including dried anchovy, dried shrimp, and dried vegetables are added to prepare roasted laver, as an example, but the technical idea of the present invention is not limited to the above example, and in addition to the dry flakes including the additive including salt and dried anchovies, dried shrimp, and dried vegetables, according to consumers' preferences and manufacturing purposes, the application amount, content, additives, etc. may be variously modified, and these modifications are included in the scope of a right of the technical idea of the present invention.


Next, a second roasting S160.


Specifically, the second roasting process S160 is a process of manufacturing seasoned laver by adding a heat source to the seasoned laver and roasting. In the second roasting process S160, the seasoned laver can be manufactured by heating the seasoned laver in a temperature range of 170° C. to 200° C. which is a temperature below the smoke point of the oil. By going through the second roasting process at a temperature below the smoke point as described above, no harmful ingredients such as benzopyrene are produced, preventing the occurrence of an obnoxious odour due to the denaturation of oil at high temperature, thereby producing seasoned laver with savoury flavour.


For reference, in the manufacture of seasoned laver, in the case of existing technologies for heating oiled laver above the smoke point, carcinogens such as benzopyrene or harmful ingredients to human body such as trans fats, active oxygen, and peroxides may be produced by denaturation of oil ingredients, and in the present invention, the formation of such harmful ingredients can be prevented.


As a result of the experiment, it was confirmed that the hemp oil does not permeate sufficiently in the second roasting process S160 when the roasting of the seasoned laver is performed below 170° C., and that harmful ingredients are generated when the roasting is performed exceeding 200° C. Therefore, the second roasting process S160 is preferably carried out in a temperature range of 190° C. to 200° C.


Finally, the cutting and packaging S170.


Specifically, the cutting and packaging process S170 is a process of cutting the seasoned laver by a certain unit, then packaging and commercializing. In the cutting and packaging process S170, the element for cutting the seasoned laver, then packaging and commercializing, may be variously modified according to the purpose of the manufacturer or user, and since the elements of such commercialization are prior art, for convenience and clarity of description of the technical idea of the present invention, a detailed description will be omitted.


Hereinafter, the manufacturing method of seasoned laver according to another embodiment of the present invention will be described in more detail.
