Description

Detailed Description of the Invention

[0001]

[Industrial application] The present invention relates to a fermented seafood product and a method for producing the same, and to impart elasticity and flavor by adding a lactic acid bacterium starter to fish meat, especially salmon ground meat, and fermenting it. Specifically, the present invention relates to a fermented gelled food such as kamaboko, which is made from salmon and trout, and is produced by fermentation with lactic acid bacteria.

[0002]

2. Description of the Related Art Generally, fish paste products are obtained by crushing fish meat together with salt, adding auxiliary ingredients such as seasonings, and heating. Kamaboko is a typical fish paste product. Kamaboko has a long history, and there are already records of its production around 1500. In addition, there are kamaboko, which is known as a local specialty, and is widely popular. Although the fish species as a material is not limited, it is preferable to use fish species that are rich in umami components, have high gel forming ability, and are inexpensive. Therefore, it is common to mix several types of fish. Walleye pollack surimi was developed in the 1955's, and due to the difficulty of securing raw material fish, dependence on walleye pollack surimi increased. As a material for kamaboko, Alaska pollack has a sufficient gel-forming ability, but has a drawback that it lacks umami taste.

[0003] In the conventional manufacturing method of kamaboko, ground fish meat is crushed, salt is added and salted. Next, seasoning such as sodium glutamate and starch as an elasticity enhancer are added and mixed, and then molded. Finally, a gel is formed by heating to obtain a product. Another common method is to leave the surimi to which salt has been added, and to slightly gel it to enhance the "feet" (elasticity, gel strength) and then heat it. Currently, when manufacturing Kamaboko made from Alaska pollack Heats the molded surimi after gelling it at a low temperature.

The salting step is a step performed to elute a sufficient amount of salt-soluble protein from the myofibrils to form a network gel. The salt added at the time of salting is at least 2.5% with respect to fish meat, and it is necessary to add 3 to 10% to increase elasticity (leg). Usually, 2.5 to 3.5% is added in relation to the taste. If the surimi to which salt is added is left to stand, the fibrous protein crosslinks and gels even without heating. This phenomenon is "sit"
It is called "sit" and the easiness of "sitting" varies depending on the fish species.
By heating, a gel of the eluted protein that is much harder than "sitting" is formed, but by heating the surimi once seated, a stronger gel can be formed.
Therefore, it is said that the fish species that are easy to sit on are suitable for the production of kamaboko, and the fish meat minced fish of Alaska pollack, which is currently widely used for the production of kamaboko, has the property of sitting well even at low temperatures.

On the other hand, although salmon has the property of returning when released, has an excellent color tone peculiar to salmon, and has a rich flavor, such as salmon, the surimi has a variety of excellent characteristics not obtained by Alaska pollack, but the surimi has a low temperature. Since it is said that it is difficult to sit in, it is not often used for manufacturing kamaboko. As described above, conventional fish gelled foods have a problem that it is difficult to use them as raw materials unless they are fish species that are comfortable to sit on.

As a gelling method of fish meat surimi other than heating, there are a method of denaturing the protein of surimi with acid to give elasticity and a method of fermenting the surimi with a microorganism to gel.

Kamaboko, which is obtained by acid-denaturing surimi protein by acid denaturation, is called "Shime Kamaboko" (Journal of Fisheries Products Technology, Vol. 6, No. 7, pages 311 to 314, No. 9).
Pages 406-409, No. 12, pages 547-550). However, there are two problems in the manufacturing method of "shimekaboko". One is the general method of making "shimekaboko" by dipping the shaped surimi in an acid solution, but "shimekaboko" gives good elasticity, but the taste of the surimi seasoned before soaking in the acid soaking process Is almost disappeared. In order to compensate for the disappearing taste, there is also a method of seasoning the soaking acid solution. Since the pH rises when the acid solution is seasoned, it is characteristic that the buffer capacity of the acid solution is increased.
The other problem is that "Shimekamaboko" does not penetrate into the central part when it is thick. This problem has not yet been overcome.

[0008] A report on a method for producing a fermented kamaboko which ferments surimi meat with microorganisms to impart gel strength, elasticity and flavor has been reported by Mie University and Sanei Saccharification Co., Ltd. using Lactobacillus plantarum as target fish species (Lactobacillus plantarum) and Lactobacillus casei (Lactobacillus casei) (Journal of Japanese Food Industry, Vol. 39, pp. 519-523, 1992), Pediococcus spp.・ Acid Lactiti (Pediococcus
Example using acidilactici (International Journal of Food Microbiology (Intern
ational Jounal of Food Microbiology) Volume 13, 143-1
(Page 56, 1991), there is an example of using Bifidobacterium as a target fish species of sardines and sea bream (Patent Publication No. Sho 61-35765). However, in these reports, walleye pollock, sardines, and hockey used as raw materials for kamaboko are easy-to-sit materials, but there are no reports of fish-fermented gelled foods made from salmon that are difficult to sit, and fish-fermented gelled foods are not reported. There are still restrictions on the raw fish species used to make food. In addition, the examples of Mie University and Sanei Saccharification Co., Ltd. only describe that the elasticity of the fermented kamaboko became lower than that before heating, but the physical properties of elasticity before heating were not shown. It is unclear to what extent the gel properties will change due to. The example of the University of New South Wales only describes changes in microbiota, and does not describe physical properties such as gel strength as food, taste, and aroma.

[0009]

[Problems to be Solved by the Invention] In the current method for producing gelled foods for fishery products, the production of non-fermented gelled foods such as kamaboko is limited to fish species where the material is easy to sit on. There is a limit to the thickness during the process, and the original flavor of the fish is lost during the acid immersion process. In addition, in the report that fermented conventional fish meat,
In many cases, the fish species used are those that are easy to sit on, and there is a problem that the restrictions on the ease of sitting of the target fish species have not been resolved. Furthermore, the previous report does not describe specific data on the physical properties of the gel after fermentation, so the involvement of fermentation is unclear.

[0010] Therefore, the problem to be solved by the present invention is to use salmon surimi as a raw material, which has been difficult to use because the surimi is difficult to sit despite having excellent characteristics such as scent, color tone and taste. The purpose of the present invention is to provide a fish-fermented gelled food product that makes use of the salmon's excellent characteristics by imparting a flavor due to fermentation of lactic acid bacteria as well as physical properties rich in gel strength and elasticity.

[0011]

[Means for Solving the Problems] According to the present invention, Leuconostoc spp.
Fermenting salmon surimi with lactic acid bacteria of the genus, Pediococcus, or Lactococcus as a starter, the breaking strain value increases with breaking strength, elastic gel is formed, and the salmon's unique flavor and color tone are impaired Therefore, the present invention has been completed, and it was found that a high-quality food product having a sourness or a flavor due to fermentation can be produced, and the present invention has been accomplished.

That is, even when the salmon surimi, which is said to be difficult to sit due to salting, is used as the raw material, the production method of the present invention allows the fermentation gelation having sufficient elasticity and gel strength as food and flavor by fermentation. It is possible to manufacture food. Salmon surimi may be frozen or non-frozen, with or without thickening agents such as starch, with or without salt, and with or without seasoning.
The salmon and trout are applicable to the surimi fish species. The fish-fermented gelled foods that are produced include kamaboko (including "special kamaboko" according to JAS standards), as well as surimi, fish ham, fish sausage, etc., using salmon as its material, and Leuconosto.
The genus c, Lactobacillus genus, Pediococcus genus, or Lactococcus genus, or one obtained by fermenting a plurality of species of microorganisms belonging to these genera as a lactic acid bacterium starter is applicable.

[0013]

[Action] Lactic acid bacteria have an action of producing an organic acid mainly of lactic acid in the fermentation process. It is considered that the generated organic acid causes mild acid denaturation of the protein of fish surimi, which improves elasticity and gel strength.
It is also possible that enzymes such as transglutaminase are produced by lactic acid bacteria during fermentation, which may affect gelation. Furthermore, it is assumed that various metabolites produced by lactic acid bacteria in the fermentation process contribute to the improvement of flavor.

[0014]

[Examples] The following outlines a method for producing a salmon fermentation gelled food and a lactic acid bacterium starter used for production.

The lactic acid bacterium medium is inoculated with the lactic acid bacterium and statically cultured. The bacterial cells are collected from the culture solution, suspended in glycerol, and then frozen and stored to obtain a frozen lactic acid bacterium starter.

Salt is added to the salmon surimi and salted. Further, distilled water, lactic acid bacterium starter and sugar are added and mixed. After degassing the mixed surimi, it is filled in a casing and fermented at 15 to 20 ° C.
