- Softening of meat includes softening of streaks of meat. That is, the meat modifier of the present invention may be, for example, a meat softener, specifically a meat streak softener.
- the combined use of protease and metal-containing yeast can provide an effective effect on meat modification as compared with the case where protease is used alone.
- This effect is also referred to as a “combination effect”.
- the combined effect includes an effect of improving the collagen-specific resolution of the protease and an effect of improving (promoting) the softening of the streaks of meat by the protease. That is, the combined use of protease and metal-containing yeast, for example, compared to the case where protease is used alone, for example, to increase the softness of the streaks of meat and the time required to soften the streaks of meat It may be possible to reduce the amount of enzyme.
- the meat modifier of the present invention contains a protease.
- Protease refers to an enzyme that hydrolyzes peptide bonds of proteins. Proteases are also called proteinases.
- the protease used in the present invention is selected from proteases derived from bacteria belonging to the genus Bacillus and proteases derived from fungi of the genus Aspergillus.

- Aspergillus fungi include, for example, Aspergillus fumigatus, Aspergillus ell storageus, Aspergillus niger, Aspergillus oryzae, and Aspergillus sperm. It is done.
- the protease can be, for example, an acidic protease, a neutral protease, or an alkaline protease.
- the protease may also be, for example, aspartic protease, serine protease, or metalloprotease.
- proteases derived from bacteria belonging to the genus Bacillus include serine proteases such as subtilisin (EC 3.4.21.62; also referred to as protin, biolase, and alcalase), and metalloprotease such as thermolysin (EC 3.4.24.27). ) And other various acidic, neutral or alkaline proteases.
- proteases derived from Aspergillus fungi include neutral proteases such as NPI and NPII, alkaline proteases such as ALP, and aspartic proteases (acidic proteases) such as PEPO.

Description
本発明は、食肉改質剤、食肉加工品の製造方法、および食肉を改質する方法に関するものである。
The present invention relates to a meat modifier, a method for producing processed meat products, and a method for modifying meat.
世界の食肉の消費量は増加傾向にあり、今後も更なる需要の高まりが予想される。食肉のおいしさを決める重要な要因の一つに、「肉のやわらかさ」が挙げられる。また、おいしさのみならず、やわらかい肉は咀嚼しやすいため、食べやすさの面でも優れ、さらに、消化効率も上昇するため、栄養摂取面でも優れる。特に、高齢化が進む先進諸国においては、肉を適度にやわらかくする食肉軟化剤等の食肉改質剤のニーズが高まっている。
Demand for meat in the world is increasing and further demand is expected to increase. One of the important factors that determine the taste of meat is the softness of meat. In addition to deliciousness, soft meat is easy to chew, so it is excellent in terms of ease of eating, and digestive efficiency is also increased, so it is excellent in terms of nutrition intake. In particular, in advanced countries with an aging population, there is a growing need for meat modifiers such as meat softeners that moderately soften meat.
食肉軟化剤としてプロテアーゼを用いる方法は、従来から行われている（特許文献１）。一般的に用いられる食肉軟化剤としては、パパイヤ由来のパパイン、パイナップル由来のブロメライン、キウイ由来のアクチニジン等が挙げられる（特許文献２、３）。しかしながら、これらの酵素を用いる場合、軟化の程度を制御することが難しく、過剰軟化によりレバー様の食感の肉となってしまうことが問題である。また、これらの酵素を用いる場合、筋原線維を主体とする赤身部位の分解は可能であるが、硬質タンパク質（コラーゲン）から構成される結合組織を多く含むスジ部位の軟化は不十分であった。
A method using a protease as a meat softener has been conventionally performed (Patent Document 1). Commonly used meat softeners include papaya derived from papaya, bromelain derived from pineapple, actinidine derived from kiwi, etc. (Patent Documents 2 and 3). However, when these enzymes are used, it is difficult to control the degree of softening, and the problem is that excessive softening results in a liver-like texture. In addition, when these enzymes are used, it is possible to decompose the lean part mainly composed of myofibrils, but the streak part containing a lot of connective tissue composed of hard protein (collagen) has not been softened sufficiently. .
一方、結合組織の構成成分であるコラーゲンやエラスチンを選択的に分解する酵素であるコラゲナーゼやエラスターゼを用いて肉の中の硬質タンパクを主に分解し、軟化する方法も知られている（特許文献４、５）。しかしながら、これらの酵素を用いる場合、上記のパパイン、ブロメライン、アクチニジンに比べて製造および調製が困難であること、硬質タンパクの分解には大量の酵素量または長時間の処理時間が必要であること、酵素量または処理時間を増やした場合でも硬質タンパク質を十分に分解するには至らず、軟化が不十分であることが課題である（特許文献６）。
On the other hand, there is also known a method of mainly degrading and softening hard proteins in meat using collagenase and elastase, which are enzymes that selectively degrade collagen and elastin, which are components of connective tissue (Patent Literature). 4, 5). However, when these enzymes are used, they are difficult to produce and prepare compared to the above papain, bromelain, and actinidine, and a large amount of enzyme or a long processing time is required to decompose hard protein. Even when the amount of enzyme or the treatment time is increased, the hard protein cannot be sufficiently decomposed, and the problem is that the softening is insufficient (Patent Document 6).
以上のように、プロテアーゼを用いた食肉軟化等の食肉改質技術には改良の余地がある。
As described above, there is room for improvement in meat modification technology such as meat softening using protease.
このように、肉の硬さの主要因の１つである結合組織を優位に軟化させる方法は未だ確立されていない。よって、本技術を確立させることで、様々な肉の好ましい改質が可能となり、食肉の更なるおいしさの向上、調理の時間の短縮といった調理簡便化、低品質肉の物性改善、硬くて破棄していた肉部位や老牛の有効利用等の食資源の有効活用等、様々なメリットが期待できる。
Thus, a method for preferentially softening connective tissue, which is one of the main factors of meat hardness, has not yet been established. Therefore, by establishing this technology, it is possible to modify various meats, improve the taste of the meat, simplify cooking such as shortening the cooking time, improve the physical properties of low-quality meat, hard and discard Various merit such as effective utilization of food resources such as meat parts and old beef that have been used can be expected.
そこで、本発明は、食肉の改質方法および食肉加工品の製造方法、並びにそれらのために好適に用いることができる食肉改質剤を提供することを課題とする。本発明は、特に、食肉の結合組織の一つであるスジ部位を軟化させる方法およびスジ部位を軟化させた食肉加工品の製造方法、並びにそれらのために好適に用いることができる食肉軟化剤を提供することを課題としてよい。
Therefore, an object of the present invention is to provide a method for modifying meat, a method for producing processed meat products, and a meat modifier that can be suitably used for them. In particular, the present invention relates to a method for softening streaks, which is one of the connective tissues of meat, a method for producing processed meat products in which streaks are softened, and a meat softener that can be suitably used for them. Providing can be an issue.

As a result of diligent research, the inventor of the present invention used a protease derived from Bacillus bacteria or Aspergillus fungi and a metal-containing yeast such as manganese-containing yeast, thereby providing a collagen-specific resolution of the protease. Has been found to be improved and the softening of streaks in meat can be promoted, and the present invention has been completed.
