Method for processing raising dried yellow corvina full of roe containing elopement

According to the present invention, only a male containing a certain amount of testis is selected from a reference group grown by raising a relative fish instead of manufacturing a oyster by processing a reference group caught in a conventional fishing and breeding under constant environmental conditions in a breeding tank on land. It relates to a method of producing a male reference group cultured gulbi containing a certain amount of testis, characterized in that the processing to the oyster ratio and a male reference group cultured gulbi containing a certain amount of testes produced by the method.

Fishermen's difficulties are increasing due to the strengthening of the WTO system and the expansion of the FTA. Recently, the fisheries industry is further stagnant due to the spike in oil prices and rising international raw material prices, and the development of new high-income aquaculture technology is emerging to revitalize regional fisheries. .

Gulbi is a famous food that was already known to King Lee and Gyeom in the Goryeo Dynasty.The raw material, which is a reference fish, was harvested across the East China Sea and Heuksan Island when it was passed in the middle of March in the lunar calendar. It is rich and golden in color, salted with sun-dried sea salt, washed with clean water, and dried in the clear west sea of Hanniwind, which has been known for its exceptional taste. In addition, it is recorded that the oysters are beneficial to the stomach and are good for stomach uptake, planting, and neurological gastrointestinal disorders, and have no poison and are good for nutrition of children, the elderly, and patients.

Larimichthys polyactis, which is a material of Glory Oyster, is a fish included in the family of aquatic fish. It is generally called early, and the length of the sea urchin is about 30cm, the tail stalk is thin and long with grayish golden color. Lips are reddish and live on a continental shelf about 150m deep. It lays eggs in the spring. During the spawning season, the body color becomes clear and the group comes up close to the surface to make a big cry by using the bures.

It is distributed in Korea's Yellow Sea, South Sea, East China Sea, Taiwan, etc., in late March to mid-April, latitude in Jeonbuk, from late April to mid-May, to Yeonpyeong-do, and to early June, to the sea near Taehwado. It is a peculiar fish species, which is located in the north, and has an eccentric nature, and when exposed to air, the bream ruptures and easily dies even in small wounds. In Korea, the spawning grounds were caught in the waters near Yeonpyeong-do and Yeonggwang, but in recent years, overfishing has not only reduced the number but also the size.

In particular, the reference group, which was dried during the spawning season, was regarded as an egg oyster. The Yeonggwang area has been the main axis of the Yeonggwi fishing village, which earns KRW 350 billion annually, producing 19,000 tons of oysters annually as the main homeland of oysters, but recently, it has been damaged by the production of oysters by imports from China and other places. Due to the overfishing of fish stocks due to the development of fisheries technology, reference fishing grounds are no longer formed in the West Sea. Moreover, domestic brand value is falling due to the low price of early imports from China, which is shaking the domestic oyster industry.

As a result, it is required to develop high value-added products for the recovery of Yeongggul Oyster, which is a local specialty, and the reference fisheries, which have been harvested annually through resource recovery, are miniaturized by artificial seedlings. There is an urgent need to restore the current stocks of fish stocks.

Accordingly, the present inventors have developed a reference method for terrestrial fish, which is a local specialty fish species on the west coast, by registering artificial fish seedlings, and registering it as a domestic registration patent publication No. 10-1059515, contributing to resource recovery of the reference group.

On the other hand, in order to cope with the development and emergence of many functional foods, to differentiate from the late local oyster industry, and to stabilize the local industry through the continuous development of the oyster industry, it is urgently required to develop oysters or develop products. to be.

In this situation, the present inventors provide a method for processing male farmed oysters containing a certain amount of testicles using a farmed reference, as well as securing a raw material of oysters in a situation where a natural reference device is being miniaturized every year due to overfishing. To contribute to stagnant oyster processing.

Korean Patent Application Publication No. 10-2000-027673 discloses freezing and pulverization of frozen oysters with the head and scales removed below -30 ° C, and 1-5 parts of red pepper paste and additives in 1-2 oyster powders dried at 10-40 wt% moisture. After mixing, it is matured in the shade to produce a kochujang oyster. Korean Patent Application Publication No. 10-2007-042358 discloses a step of drying and treating dried oysters in a salt solution mixed with an organic acid and a spirit in a low concentration salt solution in order to prevent germ contamination and obesity and to remove fishy oysters. Remove the by-products by peeling and cutting to a certain size to obtain premature flesh, and add red pepper paste to the red pepper paste with the extract and moisturizer of green tea, ginger or donkey and mature at 20-25 ℃. A manufacturing method is disclosed. Korean Patent Publication No. 2010-0130110 discloses a method for preparing oysters that can provide antimicrobial and antioxidant effects using useful microorganisms and alkaline reduced water, and Korean Patent No. 0994673 uses hot air drying and cold air drying. A method for producing hygienic dry oysters is disclosed. However, the above prior art is limited to a method of selectively processing fish caught in a fish and processing them into oysters, and selecting only males having testis from a reference group grown to a fixed size to secure fish and processing them into oysters. The manufacturing method is not disclosed.

The present invention is derived from the above requirements, the present invention is separated from the natural raw material caught in the existing fishery and separated from the way of processing in the oysters of similar quality by a certain size, farmed in the breeding tank of the land Only the males having a certain amount of testis in the reference period are selected and processed through the process of freezing and thawing, and then processed into oysters using sea breeze, and processed into male oysters containing 100% of testes. To produce a consistent oyster with a quality.

In order to solve the above problems, the present invention contains a certain amount of testis, characterized in that only the males having a certain amount of testis out of the reference period grown and reared from the parent fish and grown in a land breeding tank and processed into oyster ratio Provided are a method of processing a reference male cultivation ratio and a male reference cultivation ratio containing testes prepared by the method.

More specifically, when the water temperature of the reference breeding tank falls in November, maintaining the constant water temperature by warming the water temperature to 12 ° C. at the time when the sea water temperature drops to 12 ° C. or lower; From November to March of the following year to maintain the water temperature at 12 ~ 13 ℃ feed feed formulated to form and improve the testis; Only males full of stomachs are screened alive in mid-March through late March, when the males reach their peak size from February to March when they mature. The water content at the time of screening is higher than that of natural products, usually 78 ~ 79%. The step of storing the selected reference group males by rapidly freezing them at -20 ° C to -30 ° C as alive, and thawing (water content of 74-76%) by processing them into oysters 18-24 hours before processing the rapidly-frozen reference group into oysters. Provided is a male reference group cultured gulbi ratio processing method comprising a testis, characterized in that consisting of a step.

According to the present invention, since only males having a certain level of testis are selected from the cultured reference periods, 100% of the oysters having a constant quality and manufactured are processed into male reference group oysters containing a certain amount of testicles, thereby distinguishing them from the existing ones. It has the advantage of providing consumers with high quality oysters, including% testis.

In addition, by supplying nutrient-enriched feeds while maintaining a constant water temperature during aquaculture in the breeding tank of the reference period, it is possible to grow early in a healthier state by improving the stamina of the reference group, thereby improving the early meat quality and testicles that become raw materials. You can.

Particularly, processing the oyster by fertilizing seedlings fertilized from parent fish can save cost and time than sorting and processing the reference group caught by conventional fishery. The quality is maintained and the taste and texture can be enhanced to be processed into oysters suitable for all consumers' tastes.

In order to achieve the object of the present invention,

(a) selecting only males from the reference stages in which the reared fertilized eggs from the rearing broods were reared in a land breeding tank;

(b) freezing and storing the selected male reference group of step (a); And

(c) thawing the stored male reference group of step (b) to provide a method for processing a reference group male cultured gulbi containing testis, characterized in that the processing comprises a step of processing.

The method of processing a male reference group cultured oyster ratio containing testis of the present invention can be carried out for 4-6 months while maintaining the reference group cultured water temperature of step (a) at 12 ~ 15 ℃. More specifically, during the fall of November, when the seawater temperature drops below 12 ° C, the land breeding tank water temperature is maintained at 12 ~ 13 ° C, and the mixed feed containing fresh shrimp is kept from December to February next year. After the supply, when the January to March of the next year, while maintaining the water temperature of the tank to 13 ~ 15 ℃ to feed the compound feed and squid and cultured until March to April.

Farming by the above method, can maintain the early winter stamina to prevent diseases caused by the decline in physical strength and can be farmed as a reference that can be processed into oysters with excellent meat and taste, and as mentioned above, Testes form and develop.

In the method of processing the male reference group cultured gulbi containing testis of the present invention is mid-March to the end of March, when the testis is most developed, only the males are separated and processed into oysters, and the testis is soaked with the highest quality. It is possible to enhance the consumer's preference, and when the amount of testicles of the reference group is small, there is a problem that the preference decreases when processing with the oyster ratio.

In addition, in the method of processing a male reference group cultured gulbi containing testis of the present invention, the freezing of the selected male reference group may be carried out at -20 ° C to -30 ° C, but is not limited thereto.

In addition, in the method of processing a male reference group cultured gulbi containing testis of the present invention, the thawing in the step (c) is preferably thawed 18 to 24 hours before processing the reference group to the gulbi. The thawed male reference group has thicker scales than the natural reference group, and has a lot of moisture (78-79%), mucus, and fleshy features.

Therefore, the salt is used to remove the salt water, and the amount of salt used is about 15kg males to 0.8 ~ 1L salt amount is salted 08-12 hours, preferably 9-10 hours. When salting, it is necessary to make the salt (sprinkle less salt in the gills and oral cavity), there is an advantage of not only shortening the salting time through the salt, but also evenly well liver.

In the method of processing a male reference group cultured gulbi containing testis of the present invention, the processing with the gulbi of the step (c) is preferably shaded for 3 to 5 hours by sea wind after salting the reference group. As such, the processed oyster fertilizer occupies 67-70% (optimum 68-69%), and can be processed to consumers' favorite oyster ratio.

 In the method of processing a male reference group cultured oyster containing the testis of the present invention by vacuum-packing the processed oyster 2 or 3 by about three can be packaged for convenient use by consumers, but is not limited thereto. Vacuum packaging has the advantage of being easy to use and store, can keep the freshness continuously, consumers prefer the vacuum-packed oysters easy to purchase.

The present invention also provides a male reference group aquaculture ratio containing testes processed by the above method.

Hereinafter, embodiments of the present invention will be described in detail. However, the following examples are illustrative of the present invention, and the present invention is not limited to the following examples.

1. Breeding production of oyster production reference machine

1 is a diagram illustrating a processing method of aquaculture oyster ratio containing testis of the present invention, Figure 2 shows a reference group in the breeding, fertilization, breeding in the breeding tank of the land. A reference group for the production of aquaculture dens containing a certain amount of testis can be secured by breeding in land breeding tanks as follows.

That is, seedlings grown from young fish by hatching fertilized eggs spawned from the reference group can be nurtured in the breeding tanks on land. 3 shows a modified reference group, and FIG. 4 shows a growth change of the hatching daily reference group. 70 days after hatching, the reference group was grown to a size of about 20 mm and a total length of 60 mm.

As described above, the form of the reference group for the production of male reference group cultured gulbi containing testes grown to a certain size is as follows. Seeds grown from larvae by hatching fertilized eggs in the reference period can be nurtured in tanks. From then on, 5 ~ 7cm of fry are housed in round polypropylene tanks (3x3m) for flounder farming and managed from July. The height of the breeding tank was maintained at 100-120cm in the center of the tank, and the feeding was provided 12 times (mixed feed 1.6mm) every hour from 7:00 to 18:00 every 80 days of incubation.

9 times at 100 days of hatching (mixed feed 1.8mm), 5 times at 120 days of hatching (mixed feed 2.0mm), 3 times at 140 days of age (mixed feed 2.5mm), 2 times / day from 160 days after hatching 3.5 mm) was supplied continuously. The reason for the frequent feeding at the beginning of hatching is to reduce the official phenomenon.

The growth of the reference period shows the growth rate starting from 63mm at 70 days of hatching, 106mm at 110 days of hatching, 132.5mm at 150 days of age, and 178mm at 190 days of age. After that, it grew to 210mm at 320 days of age, and after one year, it grew to a reference period and became possible to spawn.

The method for producing a cultured oyster ratio containing a certain amount of testis of the present invention can be carried out for 4-6 months while maintaining the reference group cultured water temperature of step (a) at 11 ~ 15 ℃. More specifically, when the seawater temperature drops to 12 ℃ or lower in November of autumn, the feedstock containing raw shrimps is supplied from December to February next year while maintaining the temperature of the breeding tank to 12 ~ 13 ℃. After that, when the first to March of the following year, while maintaining the water temperature of the tank to 13 ~ 15 ℃ to feed the formulated feed and squid and cultured until March to April.

Farming in the above manner, it was possible to maintain the early winter stamina to prevent diseases caused by the decline in physical strength and can be farmed as a reference that can be processed into excellent meat and taste oysters. As described above, the male of the reference phase in the aquaculture process is the ovary is formed and the egg quality is improved.

2. Oyster processing of reference machine

Processing of the male reference group cultivars containing testes begins with the development of testes early in the water temperature control and the selection of good males.

In general, the reference group uses natural seawater while maintaining a livelihood minimum water temperature, and since egg and testis mature in 1-2 months later than in the present invention, the securing of excellent testicular oysters is delayed. In addition, the size of the fish is also fixed when coming up to the catch is necessary for discrimination and screening of male and female.

Therefore, in November, the reference period, which is farmed in breeding tanks, is maintained at 12 ~ 13 ℃ while maintaining the tank water temperature at 12 ~ 13 ℃. When the mixture is fed and feed to the squid while maintaining the temperature at 13 ~ 15 ℃ until mid-March, the testes and ovaries of the reference period is formed and the testes develop first. Testes in the maturation phase of the maturity of males are completed from February to March, and the size of the testis reaches its peak at mid-March to late March. Unlike the ovary, the testes are processed into oysters and heated to form a solid silver white in the form of fine particles. Therefore, it is important to include the testes as much as possible rather than to adjust the content to a certain amount.

Testicular content of the reference period is monitored by measuring the weight and amount of testis by sampling the reference period from November to February each month or February to February, when breeding begins at the reference farm's aquaculture farm and begins to form a testis.

 In mid-March to late March, when the size of the testis reaches its climax, only males whose stomachs are convex are selected and separated. The water content of the body is about 78 ~ 79%. In the case of female egg ventilator having egg quality, male to egg is formed one month later than April to May GSI value is 7-10%, so it is suitable to make a product, males can be selected as a product first and shipped. Fig. 5 shows a male anatomy photograph of the reference group in which testes are formed. The male of the reference phase of this photo shows that the testis is formed in the ventral part one month before the testis fully develops.

The selected male reference group is kept alive by rapid freezing at -20 ° C to -30 ° C. Normally, the freezing temperature can be lowered to -40 ℃, but unlike the large fish such as tuna, the reference body is small, so it is possible to freeze at the quality suitable for the production of oysters in the above temperature range. The water content in the fish can be reduced by freezing the raw materials.

In addition, thawing is required to process the frozen reference machine to the oyster ratio according to the shipping time, and thawing is preferably thawed from 18 to 24 hours before processing the reference machine to the oyster, and the moisture content is reduced by 3 to 4%. The moisture content of is maintained at about 74-76%. 6 shows a photograph before processing the aquaculture reference. Before processing, it can be seen that the aquaculture reference group contains water on the body surface.

The thawed male reference group has thicker scales, more mucus and more flesh than the natural reference group, and the salted salt is the salt minus the liver water, and it is used according to the amount of salt in the ratio of 0.8 to 1ℓ based on 15 kg of males. 10 hours), salt must be salted (salt less salt in the gills and oral cavity), the salt shortens the salting time and evenly spread the liver. The amount of salt can be used to fill the 1 L vessel or to fill the vessel to the 0.8 L line. The weight of a male is measured by placing a fish to be treated in a container. Three-year sun-dried salt is used for salting, and as the salting proceeds, the water content of fish is about 69 to 71%. Three-year-old salt does not use salt, and salt is spread in the fish when salted in oysters. In addition, there is an advantage that the salt absorption time is short due to the fast absorption rate of salt.

The salted reference group was dried for 3 to 5 hours by sea breeze, and was dried over the rake without bundling the reference group during sea breeze drying. After drying the sea breeze, the water content of the reference period is reduced by 1 ~ 2%, and finally it is processed to the oyster ratio of 67 ~ 70% (optimum 68 ~ 69%). Figure 7 shows the completed photo in the oyster ratio after processing the aquaculture acid reference machine.

In addition, when drying using the freezing air temperature can be blown in the range of -50 ℃ to -70 ℃, when the temperature is very low temperature, the meat quality is rapidly dried, so the texture may drop, so that the moisture content can be changed Adjust appropriately.

3. Commercialization of Reference Oyster

In the method of processing a cultured oyster fertilizer containing a certain amount of testis of the present invention can be packaged for convenient use by consumers by vacuum packing about 2-3 oysters processed by each. Normally, vacuum packaging is easy to use and store, can keep freshness, and consumers prefer to pack a small amount by vacuum, because the oysters vacuum-packed are more convenient to purchase. The sale can be packaged in a fixed number of forms in the conventional crests, but is not limited thereto.

Example  1: Sensory Evaluation of Male Reference Group Oysters

Oysters processed by the method of Example 1 of the present invention and oysters manufactured by the method of Example 1, but selected and processed only in the live state of males in February and March (Comparative Example 1) and the processing example 1 Prepared by the method of male but the testes of male oysters processed in the oysters selected in January and February when the maturity (Comparative Example 2) was recorded and the average value of these was obtained. 5: very good, 4: good, 3: normal, 2: bad, 1: very bad.

Sensory test result of male reference group gulbi Item Processing example 1 Comparative Example 1 Comparative Example 2 color 3.6 ± 0.1 3.4 ± 0.2 3.4 ± 0.4 incense 4.0 ± 0.1 3.8 ± 0.1 3.9 ± 0.2 flavor 4.3 ± 0.2 3.5 ± 0.1 3.4 ± 0.3 Overall preference 4.5 ± 0.1 3.4 ± 0.2 3.6 ± 0.1

As can be seen in Table 1, the preference for color and aroma did not show a large difference in all the oyster ratios, but the preference for the taste showed the highest oysters processed by the method of Example 1 of the present invention. In addition, the overall degree of preference shows the highest degree of preference of the oyster ratio of the present invention, it was found that the processed oysters by using a reference group screened in the most developed state of the testis in a particular month of the present invention exhibits an excellent flavor to improve the preference . In other words, the size of the testis of the reference group was most developed, and it was judged to have a synergistic effect due to the well matched texture with the chewing texture and salt.

Only a certain size is selected from the existing natural raw materials and processed into a similar quality oyster ratio, and only males having a certain level or more from the reference periods in the breeding tanks of the land are selected and frozen and thawed. And by processing with oysters by using the freezing wind, by processing with the male reference machine oysters containing 100% of the excellent testis, all the oysters can be produced in a uniform and excellent quality of oysters, including a certain amount of eggs, and dried compared to the conventional oysters processing method And by reducing the processing time and cost and time can be reduced, it is possible to provide the most suitable oysters of consumers' preferences.
