Description

本発明は、エキス成分抽出用荒節およびその製造方法に関するものであり、さらに詳しくは、旨味成分が多く、苦味成分が少なく、多孔質であるので薫香を吸着して保持し易く、しかも破砕し易いエキス成分抽出用荒節および、経済的に容易にかつ製造日数を大幅に削減できる製造方法に関するものである。   The present invention relates to a rough knot for extracting an extract component and a method for producing the same, and more specifically, because it is rich in umami components, low in bitter components, and porous, it is easy to adsorb and hold musk, and is crushed. The present invention relates to an easy-to-extract rough section for extracting an extract component, and a manufacturing method that can be economically easily performed and greatly reduce the number of manufacturing days.

従来、削り節用魚節を製造するには原料魚の焙乾処理の前に90〜95℃で30分〜180分の煮熟を行い、肉質の自己消化を阻止するとともに表面の硬質化や内部の身割れを防止する処理が行われていた。
しかしこの煮熟によって肉質が変性してしまい、その後の焙乾処理でのエキス分の増加が少ないという問題があった。
Conventionally, in order to manufacture fish buns for shaving, ripening is performed at 90 to 95 ° C. for 30 to 180 minutes before roasting of the raw fish to prevent the self-digestion of the meat quality and to make the surface hardened or internal Treatment to prevent cracking was performed.
However, there is a problem that the meat quality is denatured by this ripening, and the increase in the extract content in the subsequent roasting treatment is small.

そこで原料魚を温水で1分前後処理してエキス分の増加を図ることが提案されている(特許文献1参照)。
しかし、この方法では、エキス分の増加は増加するが、自己消化が進行し、イノシン酸が分解されヒポキサンチンが生成されるので、苦味がでる問題がある。
Thus, it has been proposed to increase the extract content by treating the raw fish with warm water for about 1 minute (see Patent Document 1).
However, this method increases the extract content, but has a problem of bitterness because autolysis progresses and inosinic acid is decomposed to produce hypoxanthine.

そこで、温水で魚肉の中心温度を55〜65℃に保持して5〜15分加熱処理した後、焙乾処理してエキス分を保持するとともにヒポキサンチン含有量を少なくする方法が提案された(特許文献2参照)。
しかしこの方法は、原料魚を温水に浸漬するためにエキス分が温水に流出し、エキス分が少なくなる問題があった。
Therefore, a method has been proposed in which the center temperature of the fish meat is maintained at 55 to 65 ° C. with hot water and heat-treated for 5 to 15 minutes, and then dried to retain the extract and reduce the hypoxanthine content ( Patent Document 2).
However, this method has a problem that the extract component flows out into the warm water because the raw fish is immersed in the warm water, and the extract component decreases.

そこで温水で加熱処理せず、蒸気やマイクロ波や遠赤外線などで加熱して表面温度を50〜70℃に5〜20分保持して自己消化酵素を失活させて、イノシン酸の分解を防ぎ、苦味の原因のヒポキサンチン生成を阻害し、その後、焙乾処理する製造方法が提案された(特許文献3参照)。
しかしこの方法では、通常行われている焙乾処理(例えば、100〜120℃で12時間)を行い、次いで、あん蒸処理(例えば、室温で12時間)を行なうという操作を、水分が20%になるまで複数回(例えば、10回)繰り返すので、手間と時間がかかり、コストアップになるという問題がある。
Therefore, heat treatment with steam, microwaves, far-infrared rays, etc. is not performed with warm water, and the surface temperature is maintained at 50 to 70 ° C. for 5 to 20 minutes to inactivate self-digesting enzymes to prevent decomposition of inosinic acid. A production method has been proposed in which hypoxanthine production that causes bitterness is inhibited, followed by roasting treatment (see Patent Document 3).
However, in this method, an operation of performing a usual drying process (for example, 100 to 120 ° C. for 12 hours) and then performing an fumigation process (for example, 12 hours at room temperature) Since it is repeated a plurality of times (for example, 10 times) until it becomes, there is a problem that it takes time and effort, and the cost is increased.

一方、焙乾処理の途中で水分が25〜55%になった時、マイクロ波を照射して、内部水分の拡散を行なうことで、あん蒸処理操作を不要とする製造方法が提案されている(特許文献4参照)。
しかし、この方法はあん蒸処理操作を不要とするものであって、原料魚の加熱処理や焙乾処理などは従来技術の通りであるので、従来技術の前記の問題を有している。
On the other hand, a manufacturing method has been proposed in which when the moisture becomes 25 to 55% in the course of the roasting treatment, the inside moisture is diffused by irradiating microwaves so that the fumigation treatment operation is unnecessary. (See Patent Document 4).
However, this method does not require the fumigation treatment operation, and the heat treatment and roasting treatment of the raw fish are as in the prior art, and thus have the above-mentioned problems of the prior art.

本発明は、エキス成分抽出用荒節およびその製造方法に関するものであり、さらに詳しくは、旨味成分が多く、苦味成分が少なく、多孔質であるので薫香を吸着して保持し易く、しかも破砕し易いエキス成分抽出用荒節および、経済的に容易にかつ製造日数を大幅に削減できる製造方法に関するものである。   The present invention relates to a rough knot for extracting an extract component and a method for producing the same, and more specifically, because it is rich in umami components, low in bitter components, and porous, it is easy to adsorb and hold musk, and is crushed. The present invention relates to an easy-to-extract rough section for extracting an extract component, and a manufacturing method that can be economically easily performed and greatly reduce the number of manufacturing days.

従来、削り節用魚節を製造するには原料魚の焙乾処理の前に90〜95℃で30分〜180分の煮熟を行い、肉質の自己消化を阻止するとともに表面の硬質化や内部の身割れを防止する処理が行われていた。
しかしこの煮熟によって肉質が変性してしまい、その後の焙乾処理でのエキス分の増加が少ないという問題があった。
Conventionally, in order to manufacture fish buns for shaving, ripening is performed at 90 to 95 ° C. for 30 to 180 minutes before roasting of the raw fish to prevent the self-digestion of the meat quality and to make the surface hardened or internal Treatment to prevent cracking was performed.
However, there is a problem that the meat quality is denatured by this ripening, and the increase in the extract content in the subsequent roasting treatment is small.

そこで原料魚を温水で1分前後処理してエキス分の増加を図ることが提案されている(特許文献1参照)。
しかし、この方法では、エキス分の増加は増加するが、自己消化が進行し、イノシン酸が分解されヒポキサンチンが生成されるので、苦味がでる問題がある。
Thus, it has been proposed to increase the extract content by treating the raw fish with warm water for about 1 minute (see Patent Document 1).
However, this method increases the extract content, but has a problem of bitterness because autolysis progresses and inosinic acid is decomposed to produce hypoxanthine.

そこで、温水で魚肉の中心温度を55〜65℃に保持して5〜15分加熱処理した後、焙乾処理してエキス分を保持するとともにヒポキサンチン含有量を少なくする方法が提案された(特許文献2参照)。
しかしこの方法は、原料魚を温水に浸漬するためにエキス分が温水に流出し、エキス分が少なくなる問題があった。
Therefore, a method has been proposed in which the center temperature of the fish meat is maintained at 55 to 65 ° C. with hot water and heat-treated for 5 to 15 minutes, and then dried to retain the extract and reduce the hypoxanthine content ( Patent Document 2).
However, this method has a problem that the extract component flows out into the warm water because the raw fish is immersed in the warm water, and the extract component decreases.

そこで温水で加熱処理せず、蒸気やマイクロ波や遠赤外線などで加熱して表面温度を50〜70℃に5〜20分保持して自己消化酵素を失活させて、イノシン酸の分解を防ぎ、苦味の原因のヒポキサンチン生成を阻害し、その後、焙乾処理する製造方法が提案された(特許文献3参照)。
しかしこの方法では、通常行われている焙乾処理(例えば、100〜120℃で12時間)を行い、次いで、あん蒸処理(例えば、室温で12時間)を行なうという操作を、水分が20%になるまで複数回(例えば、10回)繰り返すので、手間と時間がかかり、コストアップになるという問題がある。
Therefore, heat treatment with steam, microwaves, far-infrared rays, etc. is not performed with warm water, and the surface temperature is maintained at 50 to 70 ° C. for 5 to 20 minutes to inactivate self-digesting enzymes to prevent decomposition of inosinic acid. A production method has been proposed in which hypoxanthine production that causes bitterness is inhibited, followed by roasting treatment (see Patent Document 3).
However, in this method, an operation of performing a usual drying process (for example, 100 to 120 ° C. for 12 hours) and then performing an fumigation process (for example, 12 hours at room temperature) Since it is repeated a plurality of times (for example, 10 times) until it becomes, there is a problem that it takes time and effort, and the cost is increased.

一方、焙乾処理の途中で水分が25〜55%になった時、マイクロ波を照射して、内部水分の拡散を行なうことで、あん蒸処理操作を不要とする製造方法が提案されている(特許文献4参照)。
しかし、この方法はあん蒸処理操作を不要とするものであって、原料魚の加熱処理や焙乾処理などは従来技術の通りであるので、従来技術の前記の問題を有している。
On the other hand, a manufacturing method has been proposed in which when the moisture becomes 25 to 55% in the course of the roasting treatment, the inside moisture is diffused by irradiating microwaves so that the fumigation treatment operation is unnecessary. (See Patent Document 4).
However, this method does not require the fumigation treatment operation, and the heat treatment and roasting treatment of the raw fish are as in the prior art, and thus have the above-mentioned problems of the prior art.
