【０００１】
【発明の属する技術分野】
本発明は２本又は、それ以上の数の天然腸を接着剤を用いて貼り、繋ぎ合わせて長尺物としたソーセージ用のケーシング及びその製造方法に関する。
【０００２】
【従来の技術】
従来から天然腸類のケーシングは、羊腸、山羊腸、子羊腸等の羊由来のもの、豚小腸、豚大腸、豚胃等の豚由来のもの、牛大腸、牛小腸、牛膀胱、牛盲腸等牛由来のものが用いられているが、これらは屠場で内蔵より分離された原料を収集してつくられるのであり、それには先ず内容物を取り去り、内粘膜を除去し、清浄後規格分類して塩漬けにして保存される。これらの内、ソーセージ用のケーシングに関しての品質についてはサイズが均一で長さが長く、一様であると同時に、新鮮で、丈夫であり、内容物及び脂肪等の付着物が無い事と、ピンホールや損傷が無く、悪臭の無い事等も必要条件であるとされる。
本来天然腸は、１０数メートル〜２０数メートルの長いものであるが長いものでも太さが一様でなく太い部分から細い部分まで２サイズ乃至３サイズ含まれることがあり、この場合にはサイズを揃える事が優先される為、２本又は３本に切ってサイズ別に分けられて供給される。又、内容物、粘膜、脂肪等を取り除く工程で、傷を付けたり、ピンホールをあけてしまったり又、洗浄不充分であったり、塩漬けが不適格であったり、好塩菌の発生等があったりすると悪臭や赤或いは黒の色の付着が起こるばかりでなく、ケーシングがもろくなる等品質の低下を来す場合も生じたりする。従って、これらの内、ピンホールや傷のあるものは、その部分で切って２つの短いケーシングに分け、又、好塩菌発生により色素の付着したものは、適宜切って、短いものとして供給される事になる。
更に、サイズが均一で長さの長いものでも、各ケーシングの長さは一様ではなく、長さをある程度一定にする目的で、切り揃える為に、長さの短いものが発生する。
【０００３】
【発明が解決しようとする課題】
コラーゲン、セルロース、プラスチック等の人工ケーシングは、長さは長く、且つ均一である為、高速充填機による効率の良い充填作業を行う事ができるが、前記、長さが短く、且つ不揃いとなった天然腸の場合には、充填作業が途切れるばかりでなく竿掛け作業に於ける端末処理作業も、多大な労力を必要とする事になってしまうのである。したがって、人工ケーシングに匹敵する長さでしかも太さの均一な天然腸であって、効率の良い充填作業を行うことができる天然腸に対する要望がある。
【０００４】
【課題を解決するための手段】
本発明者は、塩抜きをした天然腸の末端部分同士を繋ぎ合わせるのに、例えば、粉末又は水性分散液のような形態の接着剤成分含有組成物を用いてチューブの状態のまま貼り合わせる事により、２本或いは３本又はそれ以上の天然腸を繋ぐことが出来る事を見出し、本発明を完成した。
したがって、本発明は、所定の長さを有する少なくとも２本の天然腸が互いに接着剤成分により各内腔が連通するように繋ぎ合わされているソーセージ用ケーシングにある。
また本発明は、所定の長さを有する少なくとも２本の塩抜きをした天然腸を各内腔が連通するように互いに繋ぎ合わせて長尺物としたソーセージ用ケーシングの製造方法であって、一方の天然腸の一端部の径を他方の天然腸の一端部の径よりも大とし、互いに重ね合わせようとする前記両一端部の一方または双方の所定部分へ接着剤成分含有組成物を施用し、双方の天然腸の当該一端部を各内腔が連通するように互いに重ね合わせ、これらの天然腸の一端部を互いに接合することにより長尺物としたことを特徴とするソーセージ用ケーシングの製造方法にある。
【０００５】
本発明をさらに具体的に説明する。
塩漬状態で保存されている天然腸は水を漬けて塩抜きを行うが、この塩抜きをした天然腸は膜が薄くしかも生であるため非常に柔らかく、水に湿らせたちり紙の如くそれ自体では形を保てず水の表面張力によって細い紐状になってしまう。従って、そのままの紐状で貼って繋ぎ合わせることができないため、貼り合わせる部分を例えば扁平状やチューブ状のような何らかの形態で広げた状態にする必要がある。そこで、本発明者等は鋭意検討した結果、所定の長さを有する少なくとも２本の塩抜きをした天然腸の一方の天然腸の一端部の径を他方の天然腸の一端部の径よりも大とし、互いに重ね合わせようとする前記両一端部の一方または双方の所定部分へ接着剤成分含有組成物を施用し、双方の天然腸の当該一端部を各内腔が連通するように互いに重ね合わせ、これらの天然腸の一端部を互いに接合することにより長尺物とすることにより、あたかも一本の天然腸の如くすることができることを見出した。
【０００６】
双方の天然腸を重ね合わせる方法には、例えば、一方の天然腸３を、第一の末端１ｂから他端に向かって漸次拡径する第一の部分１ａを有する第一のパイプ１の外周部へ嵌合させて、当該一方の天然腸の一端部３ｂが当該第一の末端１ｂに概ね整合するようにパイピング配置し、他方の天然腸４を、前記第一の部分の前記第一の末端の径よりも大きい径の第二の末端２ｂを有するパイプ２であって且つその第二の末端から他端に向かって漸次縮径する第二の部分２ａを有する第二のパイプ２の外周へ嵌合させて、当該他の天然腸の一端部４ｂが概ね第二の末端２ｂに整合するようにパイピング配置し、第一のパイプの第一の部分１ａを第二のパイプの第二の部分２ａ内に所定距離だけ挿入して重ね合わせた後第二のパイプ２を他の天然腸４から引き抜くことにより双方の天然腸の一端部を各内腔が連通するように互いに重ね合わせることによるか、または、一方の天然腸４の一端部４ａを半径方向外方へ真空吸引することにより拡径し、該拡径した直径よりも小さい直径を有する膨張性のパイプ状物６の外周に他方の天然腸３ａを嵌合配置し、当該他方の天然腸を嵌合配置された膨張性パイプ状物６を前記拡径させた一方の天然腸４の一端部４ａ内へ所定距離だけ挿入した状態で膨張性パイプ状物を膨張させる６’ことにより前記他方の天然腸３の少なくとも一端部３ａを膨張させ、これにより双方の天然腸の一端部３ａ，４ａを各内腔が連通するように互いに重ね合わせることよる等の方法があるが、これらに限定されるものではない。
【０００７】
接着剤成分含有組成物の施用方法は、繋ぐ為に重ね合わせる天然腸の末端部分は、２本の天然腸の内の、他方の一端部より半径の小さい方の外面に、接着剤成分含有組成物を施用し、他の１本の一末端部分によって、おおい被せる様にするか、又は、２本の天然腸の内の他の一端部より半径の大きい方の内面に接着剤成分含有組成物を施用し、他の１本の一末端部分をはめ込む様にして貼り合わせても良い。または、２本の天然腸の内の他の一端部より半径の小さい方の外面および半径の大きい方の内面双方に接着剤成分含有組成物を施用し両天然腸を重ね合わせても良い。接着剤成分含有組成物の施用は、例えば、接着しようとする重ね合わせる部分の一方または双方に、粉末状の形態の接着剤成分含有組成物をまぶすかまたは濃度０．０１％〜２０％の接着剤成分含有水性分散液を塗布する方法等があるがこれらに限定されない。
接着剤成分含有組成物を施用する前記所定の部分については、天然腸の末端からの長さに制限はないが、好ましくは、０．５ｃｍ〜２０ｃｍである。０．５ｃｍ以下では繋ぎが弱く、２０ｃｍ以上ではおおい被せる様に重ね合わせる作業が困難で実際的でないからである。
【０００８】
本発明の天然腸長尺物は、上記のように双方の天然腸を互いに接合させた後、必要に応じて、食塩等の濃厚水溶液の凝固液に浸漬して、接着剤成分を凝固させ、必要に応じてｐＨを中和し、最後に水洗する事により天然腸同士を繋ぎ合わせることができる。また、同様に順次貼り合わせることで実質的に３〜１０本の天然腸を繋ぎ合わせることができる。
【０００９】
接着剤成分含有組成物の形態には、上述のように、粉末の形態または水性分散液の形態等がある。
接着剤成分には、例えばコラーゲン，ゼラチン，卵蛋白，乳蛋白，血液蛋白，筋肉蛋白等の動物性蛋白質、大豆蛋白，小麦蛋白，唐蜀黍蛋白等の植物性蛋白質、或いはキトサン，コンドロイチン硫酸，アルギン酸ナトリウム，カルボキシメチルセルロース等の多糖類等があり、これらの内の一種若しくは、二種以上の混合物として使用することができる。
接着剤成分含有組成物中に含有させる接着剤成分の濃度は、当該成分の種類により変動し得るが、一般に、組成物の重量を基準に０．０１％〜１００％である。また、当該成分そのものもしくはそれらの混合物であっても良い。
接着剤成分含有組成物が粉末の場合には粒度は細かい方が良く特に１００メッシュパス以下が好ましく、まぶした直後に水分を吸収して水性分散液を用いたと同様になる。接着剤成分含有組成物が水性分散液の場合には、接着剤成分の濃度はその成分の種類により変動し得るが、一般に、水性分散液の重量を基準に０．０１％〜２０％が好ましい。濃度が０．０１％以下では繋ぎが弱く、２０％以上では粘度が高く塗布し難くくなるからである。
【００１０】
接着剤成分を凝固させるための食塩等の濃厚水溶液は、接着剤成分の水分を吸収した粉末或いは水性分散液が凝固するものであれば良く、食塩，硫安，芒硝，炭酸ナトリウム，リン酸ナトリウム，塩化カルシウム，水酸化カルシウム，硫酸アルミニウム，明礬等の無機塩、又はこれに塩酸，硫酸等の鉱酸を添加したもの、或いはアンモニア，水酸化アルカリを加えたもの、アルギン酸ナトリウム，カルボキシメチルセルロース等の多糖類等が使用できる。
凝固させた接着剤成分を中和する場合、用いた接着剤成分或いはその水性分散液のｐＨが酸性であれば、中性乃至弱アルカリ性に、逆にアルカリ性であれば、弱酸性乃至中性にするが、水洗を行ったとき、凝固した接着剤成分が、再溶解する事が無ければ、必ずしも中和はしなくても良い。
最後に水洗を行うが、再度、塩漬けにして保存する場合は、上記中和後、直接塩漬け保存することもできる。
【００１１】
接着剤成分含有組成物が蛋白質から成る接着剤成分の粉末又は水性分散液の場合、接着剤成分凝集架橋剤を供給してやる事で、貼り合わせた繋ぎ部分がより一層強固なものとすることができる。接着剤成分凝集架橋剤を供給する方法は、前記施用した接合した天然腸と共に架橋剤水溶液に浸漬するか、或いは、予め、接着剤成分含有組成物中、例えば、粉末又は水性分散液に添加しておく事もできる。用いられる接着剤成分凝集架橋剤には、燻液，カラメル液等の木材や糖類の加熱処理抽出物、グルタルアルデヒド，グリオキザール等のアルデヒド類、キシロース，グルコース，マンノース，ガラクトース等の還元糖等弱酸性乃至アルカリ性で蛋白質と反応して接着剤成分の水性分散液を水に不溶化させ得るもの等があるが、接着剤成分を凝集架橋し得るものであればどのような凝集架橋剤であっても良い。
接着剤成分凝集架橋剤の濃度は、架橋剤の種類により変動するが、例えば、接着剤成分の粉末をまぶした又は水性分散液を塗布した天然腸を、接着剤成分凝集架橋剤水溶液に浸漬する場合に於いては、燻液、カラメル液の場合、０．１％〜１００％（市販のままの原液）、アルデヒド類の場合、接着剤成分凝集架橋剤水溶液の重量を基準に０．００１％〜２％、還元糖類の場合、接着剤成分凝集架橋剤水溶液の重量を基準に０．０１％〜１０％の各濃度を用い得る。又、予め接着剤成分含有組成物粉末に添加しておく場合に於いては接着剤成分含有組成物の重量を基準に０．０１〜１．０％を又、水性分散液に添加しておく場合に於いては、各々、浸漬する場合の液の濃度の１／５〜１／１０の濃度であれば良い。
【００１２】
蛋白質から成る接着剤成分含有組成物を施用し、接着剤成分凝集架橋剤を供給し、各末端部分を重ね合わせ接合した２本の天然腸は、重ね合わせた部分の接着剤成分含有組成物の水分を吸収した接着剤成分と、天然腸のコラーゲンを凝固脱水しながらｐＨを４．０以上に上げ、含まれる接着剤成分凝集架橋剤により接着剤成分を架橋してやる事が好ましい。すなわち、２本の天然腸の重ね合わせた部分を、通常、ｐＨを４．０〜１３．５に保った無機塩濃厚水溶液に浸漬するか、或いは、この無機塩濃厚水溶液を重ね合わせた部分に塗布してやる事で達成できる。
一般に、液のｐＨはｐＨ４．０以下では反応しないか又は架橋反応に時間がかかり、ｐＨ１３．５以上ではアルカリが強すぎ、後の水洗工程で時間がかかり、実際的でない。又、液のｐＨが４．０〜８．５であり、この工程の後に再度塩漬けにして保存する場合は、水洗工程を省き直接塩漬け保存する事で、架橋剤の添加量を少なくし、且つ、塩漬け保存中に架橋反応を完結させる事が出来る。
無機塩の種類は、食塩、硫安、芒硝、リン酸ナトリウム、炭酸ナトリウム等の飽和水溶液に水酸化アルカリ、アンモニア等を適宜添加してｐＨを調整して用いる。架橋の為の反応時間は用いる架橋剤により多少異なるが、通常、１分間乃至１２０分間行う。架橋反応終了後、水洗により脱塩し、ソーセージエマルション充填用に供する。
【００１３】
接着剤成分が多糖類の場合には直接又は、前記食塩等の無機塩の濃厚水溶液により脱水凝固させた後に、前記キトサン，塩化カルシウム，水酸化カルシウム，硫酸アルミニウム，明礬等の多価陽イオン化合物か、又はアルギン酸ナトリウム，カルボキシメチルセルロース等の多価陰イオン化合物を適宜用いる事によって、脱水凝固と凝集架橋を同時に行うことが可能である。これも必要に応じて中和と水洗を行ってソーセージエマルジョン充填用に供する。
【００１４】
天然腸の末端部を拡張させるために用いる器具、例えば、パイプ等の材質はプラスチックのほか、例えば、ガラス、アルミニウム、ステンレススチール、ゴム管、軟質プラスチック等が可能であり、また、器具の形状は、定形のものについては、例えば、テーパーのついたまたはテーパーのつかないパイプであり、膨張性のものについては、例えば、細長いゴム風船、プラスチックやセルロース製のソーセージケーシング等内側から圧力等により膨らますことができる物である。また、真空吸引するための手段は、例えば、通気性のある内管と通気性のない外管とからなる二重管内を減圧に保ち、この内管に天然腸の末端部分を入れてチューブ状に広げる等の方法である。
【００１５】
【実施例】
実施例により本発明をさらに詳細に説明する。
【００１６】
（実施例１）
塩漬け羊腸のサイズ２０〜２２ｍｍの３メートルアップ品と７メートルアップ品とを用意し、水洗して、塩抜きを行った。これとは別に、天然腸ケーシングをパイピングする場合に用いると同様のパイプの片一方に図１に示す如く、長さ１０ｃｍ，末端１ｂがそこから他端に向かって部分的に漸次拡径する最小直径１９ｍｍ〜最大直径２１ｍｍのテーパー形状の第一のテーパー部分１ａを設けたパイプ１を用意した。又、別のパイプにも図２に示す如く、長さ１０ｃｍ、末端２ｂが最大直径部を有し他端に向けて部分的に漸次縮径する最大直径２２ｍｍ〜最小直径２０ｍｍの逆向きのテーパー形状の第二のテーパー部分２ａを設けたパイプ２を用意した。塩抜きを行った天然腸の内、３メートルアップ品から３〜５ｍ，５〜７ｍのものを、７メートルアップ品から、８〜１０ｍ，１０〜１２ｍのものを選び出し、長さ別に４種に分け、この中から、２本の長さの和がほぼ１５ｍになる様に２本の天然腸（３，４；図３を参照）を取り出し、図３に示す如く、パイプ１およびパイプ２の直径１０ｍｍのパイピング部１ｄ、２ｄに各々の天然腸３、４をパイピングすると共に、さらに、各天然腸３、４の末端部分３ａ、４ａをそれぞれ、パイプの第一および第二のテーパー部分１ａ、２ａを覆う様に被せた。
一方、牛皮由来のコラーゲン繊維分散物と、酵素可溶化コラーゲンの乾燥物換算４：１に混合したコラーゲン水性分散液を濃度１．０％ｐＨ３．０に調整し準備した。
前記、テーパー部分１ａにパイピングされた天然腸３の一末端３ｂから約８ｃｍの長さの末端部分３ａを、コラ−ゲン水性分散液に浸漬しゆっくり引き上げる。次いで、図３に示す如く、このパイプ１のテーパー部１ａを、他方の天然腸４の末端部分４ａをテーパー部２ａにおおい被せた状態のパイプ２の該テーパー部分２ａに対して、挿入する。次いで、パイプ２のテーパー部２ａ上にある天然腸４の末端部分４ａを所定距離だけ図３中の矢印Ｂ方向へ引き出すようにパイプ１のテーパー部１ａ上におおい被せ、パイプ１のテーパー部１ａ上の天然腸３，４の末端部分３ａ、４ａが二重になる様にしながらパイプ２を図３中の矢印Ａ方向へ引き離し、パイプ２を、これにパイピングしてあった天然腸４から全て通過させて、引き抜いた。
次いで、図４に示す如く、このように二本の天然腸が重なって接合して連結されているパイプ１のテーパー部分１ａ、すなわち、天然腸３、４の末端部分３ａ、４ａを、ｐＨ８に調整した飽和食塩水に１０分間浸漬し、両末端部分３ａ、４ａ間のコラーゲン水性分散液を脱水凝固させた後、水洗し天然腸３からをパイプ１を図３中矢印Ｂ方向へ全て引き抜いた。長さ約１４．８ｍのソーセージ用ケーシングが得られた。これにより、二重の天然腸３、４は互いの末端部分３ａ、４ａ部分で接着されて接合部５を形成した。これは塩漬けにして保存した。
【００１７】
（実施例２）
実施例１に於いて、天然腸３の一末端３ｂから約８ｃｍの長さをコラーゲン水性分散液に浸漬し、ゆっくり引き上げたものについて、次の様に処理した。
市販の木材由来の燻液を水により５倍に希釈したｐＨ２．９の液に、上記コラーゲン水性分散液の付着した部分を５秒間浸漬し、次いで、実施例１と同様にパイプ１および２の天然腸３および４を、二重に重ね、パイプ２を引き抜いた。更に、パイプ１のテーパー部分１ａ、すなわち、天然腸３、４の末端部分３ａ、４ａをｐＨ１１．５に調整した飽和食塩水に１０分間浸漬し、両末端部分３ａ、４ａ間の、燻液を含むコラーゲン水性分散液をアルカリ性にすると同時に脱水凝固させた後、水洗して、塩とアルカリを除き、パイプ１から天然腸を引き抜いた。貼り合わせた接合部５は、実施例１よりいくらか柔軟性が減少しており、燻液による着色が僅かに見られた。
長さ約１５．２ｍのソーセージ用ケーシングが得られ、これも塩漬けにして保存した。
【００１８】
（実施例３）
実施例１に於いて、コラーゲン水性分散液に予め、燻液を全体の１％宛添加しておく事と、二重にした天然腸とコラーゲン水性分散液を脱水凝固させる飽和食塩水の液のｐＨを１２．０にする以外は実施例１と同様に行ったところ、実施例２と同様に、貼り合わせ部分はいくらか柔軟性が減少していたが、燻液による着色は殆ど見られなかった。
長さ約１５．１ｍのソーセージ用ケーシングが得られ、これも同様に塩漬けにして保存した。
【００１９】
（実施例４）
実施例１に於いて、牛皮由来のコラーゲン水性分散液を用いる代わりに、カルボキシメチルセルロースの濃度５．０％、ｐＨ７．５の水性分散液を準備した。コラーゲン水性分散液を用いたと同様に、天然腸３の末端部分３ａをテーパー部１におおい被せたパイプ１の該テーパー部分１ａの先端１ｂから約８ｃｍの長さを、上記カルボキシメチルセルロ−ス水性分散液に浸漬しゆっくり引き上げる。次いで、このパイプ１のテーパー部１ａを他方の天然腸４の末端部分４ａをテーパー部２ａにおおい被せたパイプ２の該テーパー部分２ａに対して、挿入する。次いで、パイプ２のテーパー部２ａ上にある天然腸４の末端部分４ａを図３中矢印Ｂ方向へ引き出すようにパイプ１のテーパー部１ａ上におおい被せ、パイプ１のテーパー部１ａ上の天然腸３、４の末端部分３ａ、４ａが二重になる様にしながらパイプ２を図３中矢印Ａ方向引き離し、パイプ２を、これにパイピングしてあった天然腸４から全て引き抜いた。
次いで、図４に示す如く、このように二本の天然腸が重なって接合して連結されているパイプ１のテーパー部分１ａ、すなわち、末端部分３ａ、４ａをｐＨ４．５に調整したアンモニウム明礬２０％水溶液に１０分間浸漬し、両末端部分３ａ、４ａ間のカルボキシメチルセルロースの水性分散液を脱水凝固と同時に、凝集架橋させた後、水洗し天然腸３、４からパイプ１を引き抜いた。
長さ１４．９ｍのソーセージ用ケーシングが得られ、これも同様に塩漬けにして保存した。
【００２０】
（実施例５）
実施例１と同様に、二本の天然腸３、４をそれぞれパイプ１，パイプ２に対してパイプのテーパー部分１ａ，２ａをおおう様にかぶせてパイピングし、パイプ１のテーパー部分１ａの天然腸の上から、キシロ−スを重量比で０．０５％宛て添加した卵蛋白の２００メッシュの粉末を均一にまぶす。次いで、パイプ１のテーパー部分１ａを、パイプ２のテーパー部分２ａ挿入し、次いで、実施例１と同様にパイプ２の天然腸を、二重に重ねた後パイプ２を引き抜いた。更に、このように二本の天然腸が重なって接合して連結されているパイプ１のテーパー部分１ａを、ｐＨ８．０に調整した飽和食塩水に１２０分間浸漬し、二重の天然腸５とこれにはさまれた、キシロースを含む水を吸収した卵蛋白をアルカリ性にすると同時に脱水凝固させた後、水洗は行なわずに天然腸からパイプ１を引き抜いた。貼り合わせた接合部５は、実施例１より柔軟性が減少していたが、着色は見られなかった。
長さ１５．２ｍのソーセージ用ケーシングが得られ、これも同様に塩漬けにして保存した。
【００２１】
（実施例６）
実施例１と同様にして選び出した天然腸３の１本を、図５に示す一端部が閉塞している膨張性のパイプ状物６（常圧時の直径１０ｍｍのゴム風船）にパイピングし、天然腸３の先端部３ａと膨張性パイプ状物６の先端部６ａを揃えて天然腸の皺を伸ばした。別に、他の天然腸４の末端部分を、図６および図７に示す多数の通気孔７ａを有する内径２２ｍｍの内管部７ｂと通気孔のない外管部７ｃとの間に吸引室７ｄを形成した二重管７の内管部７ｂ内に挿入する。次いで、吸引室７ｄを吸引口７ｅから吸引することにより減圧して天然腸４を吸引してこの末端部分４ａを拡径した。実施例１に用いたコラーゲン液に前記天然腸をパイピングしたパイプ状物６の先端部分６ａを浸漬しゆっくり引き上げ、図８に示す如く、吸引によって拡げた二重管７の内管部７ｂ内の天然腸４の末端部分４ａ内に差し込む。次いで、パイプ状物６に空気を入れて膨らませて図９に示す膨張パイプ状物６’とし、コラーゲンを挟んで内側と外側の二枚の天然腸３、４を密着させて接合部５を形成した。その後、膨張パイプ状物６’の空気を少し抜き、二重管７の吸引室７ｄ内には空気を入れて陽圧にしながら密着させて接合した天然腸３、４とパイプ状物とを二重管７から引き抜いた。次いで、ｐＨ４．５に調整した０．００２％のグルタルアルデヒドを含む飽和食塩水溶液にパイプ状物を天然腸３、４と共に１５分間浸漬した後水洗し、パイプ状物の空気を抜いてパイプ状物６を天然腸から引き抜いた。１５．０ｍのソーセージ用ケーシングが得られ、これも塩漬けにして保存した。
【００２２】
（実施例７）
上記実施例１〜６に於いて制作した各々約１５ｍのソーセージケーシングを、各１０本ずつ用意し、塩抜き後、ソーセージエマルションを充填し、燻煙処理、蒸煮を行って、スモークソーセージを製造して、リンク部分をカットする前に調査して次の結果を得た。
【表１】

表１の結果から分かるように、本発明のソーセージケーシングは、従来の人工ソーセージケーシングと同様に効率の良い充填作業を行うことができることが確認できた。
【００２３】
【本発明の効果】
長さが短く、しかも長さが不揃いの天然腸を適宜選び出し本発明により繋ぎ合わせる事により、長く、且つ長さのほぼ均等なソーセージ用ケーシングが得られ、これを用いる事によって、ソーセージ充填作業が途切れることが無く、更に、竿掛け作業に於ける端末処理作業も少なくなり、ソーセージ製造を効率良く行うことが出来る事が判明した為、従来短く使用価値の低かった天然腸を高品質のソーセージケーシングに変える事ができる。

BACKGROUND OF THE INVENTION
The present invention relates to a casing for sausage that is made by attaching two or more natural intestines using an adhesive and joining them together to form a long product, and a method for producing the same.
[0002]
[Prior art]
Conventionally, natural intestine casings are derived from sheep such as sheep intestine, goat intestine, lamb intestine, etc., derived from pigs such as pig small intestine, pig large intestine, pig stomach, cow large intestine, cow small intestine, cow bladder, cow cecum etc. Cattle-derived products are used, but these are made by collecting the raw materials separated from the built-in in the slaughterhouse. First, the contents are removed, the inner mucous membrane is removed, and the product is classified after cleaning. Stored in salt. Among these, regarding the quality of the sausage casing, the size is uniform, long and uniform, and at the same time, it is fresh and strong, and there is no deposit such as contents and fat. It is said that there are no holes, damage, and no bad odor.
Naturally, the natural intestine is a long one of 10 to 20 meters, but even long ones are not uniform in thickness, and may be included in 2 to 3 sizes from thick to thin. Since it is given priority to align, it is cut into two or three pieces and supplied by size. Also, in the process of removing contents, mucous membranes, fats, etc., scratches, pinholes, inadequate cleaning, inadequate salting, generation of halophilic bacteria, etc. If there is, not only bad odor and red or black color adhesion may occur, but also the quality may be deteriorated such that the casing becomes brittle. Therefore, of these, pinholes and scratched ones are cut at that part and divided into two short casings, and those with pigments attached due to the generation of halophilic bacteria are cut appropriately and supplied as short ones. It will be.
Furthermore, even if the size is uniform and the length is long, the length of each casing is not uniform, and in order to make the length constant to some extent, a short length is generated in order to cut the length.
[0003]
[Problems to be solved by the invention]
Artificial casings made of collagen, cellulose, plastic, etc. are long and uniform, so they can be filled efficiently with a high-speed filling machine, but the length is short and uneven. In the case of natural intestines, not only filling work is interrupted, but also the terminal processing work in the hanging work requires a great deal of labor. Therefore, there is a demand for a natural intestine that has a length comparable to that of an artificial casing and has a uniform thickness and can perform an efficient filling operation.
[0004]
[Means for Solving the Problems]
The present inventor uses, for example, an adhesive component-containing composition in the form of a powder or an aqueous dispersion to bond the end portions of the salted natural intestine together in a tube state. As a result, it was found that two, three or more natural intestines can be connected to complete the present invention.
Therefore, the present invention resides in a sausage casing in which at least two natural intestines having a predetermined length are connected to each other so that each lumen communicates with each other by an adhesive component.
The present invention also relates to a method for producing a sausage casing having a predetermined length, which is obtained by connecting at least two salted-out natural intestines so that each lumen communicates with each other. The diameter of one end of the natural intestine is larger than the diameter of one end of the other natural intestine, and the adhesive component-containing composition is applied to one or both predetermined portions of the one end to be overlapped with each other. The production of a sausage casing characterized in that the end portions of both natural intestines are overlapped with each other so that the respective lumens communicate with each other, and the end portions of these natural intestines are joined together to form a long product Is in the way.
[0005]
The present invention will be described more specifically.
The natural intestines preserved in the salted state are soaked in water, but the salted natural intestines are very soft because they are thin and raw, so that they are moistened with water and are like paper. The shape itself cannot be maintained, and it becomes a thin string due to the surface tension of water. Therefore, since it cannot be pasted and joined together in the form of a string as it is, the part to be pasted needs to be spread in some form such as a flat shape or a tube shape. Therefore, as a result of intensive studies, the present inventors have determined that the diameter of one end of one natural intestine of the natural intestine having a predetermined length and the salt removed is larger than the diameter of one end of the other natural intestine. The adhesive component-containing composition is applied to one or both predetermined portions of the one end portions to be overlapped with each other, and the end portions of both natural intestines are overlapped with each other so that the respective lumens communicate with each other. In addition, it has been found that by making one end portion of these natural intestines into a long product by joining them together, it can be made like a single natural intestine.
[0006]
In the method of overlapping both natural intestines, for example, the outer peripheral portion of the first pipe 1 having a first portion 1a that gradually expands the diameter of one natural intestine 3 from the first end 1b toward the other end. Are fitted so that one end 3b of the one natural intestine is substantially aligned with the first end 1b, and the other natural intestine 4 is connected to the first end of the first portion. To the outer periphery of the second pipe 2 having a second end 2b having a diameter larger than the second end 2b and having a second portion 2a gradually decreasing in diameter from the second end toward the other end. Fitting and piping arrangement so that one end 4b of the other natural intestine is generally aligned with the second end 2b, and the first portion 1a of the first pipe is the second portion of the second pipe. After inserting a predetermined distance into 2a and superimposing the second pipe 2 on another natural intestine 4 By pulling out, one end of both natural intestines are overlapped with each other so that each lumen communicates, or one end 4a of one natural intestine 4 is vacuum-extracted radially outward to increase the diameter. Then, the other natural intestine 3a is fitted and arranged on the outer periphery of the expandable pipe 6 having a diameter smaller than the expanded diameter, and the other natural intestine is fitted and arranged. 6 'is expanded to expand at least one end 3a of the other natural intestine 3 by expanding the expandable pipe-like material in a state in which 6 is inserted into the one end 4a of one natural intestine 4 whose diameter has been expanded by a predetermined distance. Thus, there is a method such as superimposing the one

end portions

3a and 4a of both natural intestines so that the respective lumens communicate with each other, but the method is not limited thereto.
[0007]
The application method of the adhesive component-containing composition is such that the end portion of the natural intestine to be overlapped is connected to the outer surface of the two natural intestines with the smaller radius than the other one end. The composition containing the adhesive component is applied to the inner surface of one of the two natural intestines having a larger radius than the other end of the two natural intestines. May be applied, and the other one end portion may be fitted together. Alternatively, the adhesive component-containing composition may be applied to both the outer surface with the smaller radius and the inner surface with the larger radius than the other one end of the two natural intestines, and the two natural intestines may be overlapped. Application of the adhesive component-containing composition is performed by, for example, spraying the adhesive component-containing composition in powder form on one or both of the overlapping portions to be bonded, or bonding at a concentration of 0.01% to 20%. Although there is a method of applying an agent component-containing aqueous dispersion, it is not limited thereto.
The predetermined portion to which the adhesive component-containing composition is applied is not limited in length from the end of the natural intestine, but is preferably 0.5 cm to 20 cm. This is because the connection is weak at 0.5 cm or less, and it is difficult and practical to superimpose it so that it can be covered at 20 cm or more.
[0008]
The natural intestine long product of the present invention, after joining both natural intestines as described above, is immersed in a coagulation liquid of a concentrated aqueous solution such as salt, if necessary, to coagulate the adhesive component, The natural intestines can be joined together by neutralizing the pH as necessary and finally washing with water. Similarly, 3 to 10 natural intestines can be joined together by sequentially laminating.
[0009]
The form of the adhesive component-containing composition includes, as described above, a powder form or an aqueous dispersion form.
Examples of adhesive components include animal proteins such as collagen, gelatin, egg protein, milk protein, blood protein, and muscle protein, plant proteins such as soybean protein, wheat protein, and pepper protein, or chitosan, chondroitin sulfate, and alginic acid. There are polysaccharides such as sodium and carboxymethyl cellulose, and one of these can be used, or a mixture of two or more.
The concentration of the adhesive component contained in the adhesive component-containing composition may vary depending on the type of the component, but is generally 0.01% to 100% based on the weight of the composition. Moreover, the said component itself or those mixtures may be sufficient.
When the adhesive component-containing composition is a powder, the particle size should be finer and particularly preferably 100 mesh pass or less, which is the same as when an aqueous dispersion is used by absorbing moisture immediately after the dusting. When the adhesive component-containing composition is an aqueous dispersion, the concentration of the adhesive component may vary depending on the type of the component, but is generally preferably 0.01% to 20% based on the weight of the aqueous dispersion. . This is because when the concentration is 0.01% or less, the connection is weak, and when the concentration is 20% or more, the viscosity is high and the coating becomes difficult.
[0010]
The concentrated aqueous solution such as salt for coagulating the adhesive component may be any powder or aqueous dispersion that absorbs the moisture of the adhesive component, and can coagulate salt, ammonium sulfate, sodium sulfate, sodium carbonate, sodium phosphate, Inorganic salts such as calcium chloride, calcium hydroxide, aluminum sulfate, and alum, or those added with mineral acids such as hydrochloric acid and sulfuric acid, or those added with ammonia or alkali hydroxide, sodium alginate, carboxymethylcellulose, etc. Sugars and the like can be used.
When neutralizing the solidified adhesive component, if the pH of the used adhesive component or its aqueous dispersion is acidic, it is neutral to weakly alkaline, and conversely if it is alkaline, it is weakly acidic to neutral. However, it is not always necessary to neutralize the solidified adhesive component if it does not re-dissolve when washed with water.
Finally, it is washed with water, but when it is stored in a salted state again, it can be stored in a salted state directly after the neutralization.
[0011]
In the case where the adhesive component-containing composition is a powder or aqueous dispersion of an adhesive component made of protein, the bonded joint portion can be made even stronger by supplying an adhesive component cohesive crosslinking agent. . The method of supplying the adhesive component cohesive cross-linking agent is either immersed in the aqueous solution of the cross-linking agent together with the applied bonded natural intestine, or previously added to the adhesive component-containing composition, for example, a powder or an aqueous dispersion. You can also keep it. Adhesive component cohesive crosslinking agents used include wood and sugar heat treatment extracts such as smoked liquid and caramel liquid, aldehydes such as glutaraldehyde and glyoxal, and weak sugars such as reducing sugars such as xylose, glucose, mannose and galactose There are those that are alkaline and can react with the protein to insolubilize the aqueous dispersion of the adhesive component in water, but any aggregation cross-linking agent may be used as long as it can aggregate and cross-link the adhesive component. .
The concentration of the adhesive component aggregation cross-linking agent varies depending on the type of the cross-linking agent. For example, a natural intestine coated with powder of the adhesive component or coated with an aqueous dispersion is immersed in the aqueous solution of the adhesive component aggregation cross-linking agent. In the case of a liquid or caramel solution, 0.1% to 100% (stock solution as it is commercially available), in the case of aldehydes, 0.001% based on the weight of the adhesive component aggregation cross-linking agent aqueous solution In the case of ˜2% reducing sugars, each concentration of 0.01% to 10% can be used based on the weight of the adhesive component aggregation crosslinking agent aqueous solution. In addition, when added to the adhesive component-containing composition powder in advance, 0.01 to 1.0% based on the weight of the adhesive component-containing composition is added to the aqueous dispersion. In some cases, the concentration may be 1/5 to 1/10 of the concentration of the liquid in the case of immersion.
[0012]
Two natural intestines obtained by applying an adhesive component-containing composition comprising a protein, supplying an adhesive component coagulating cross-linking agent, and superposing and joining each terminal portion are the components of the adhesive component-containing composition of the overlapped portion. It is preferable to increase the pH to 4.0 or higher while coagulating and dehydrating the collagen component of the natural intestine with the moisture-absorbing adhesive component, and crosslinking the adhesive component with the contained adhesive component aggregation cross-linking agent. That is, the overlapping part of the two natural intestines is usually immersed in a concentrated inorganic salt aqueous solution whose pH is maintained at 4.0 to 13.5, or the overlapping part of this inorganic salt concentrated aqueous solution is used. This can be achieved by applying.
In general, the pH of the solution does not react at pH 4.0 or lower, or it takes time for the crosslinking reaction, and at pH 13.5 or higher, the alkali is too strong, and it takes time for the subsequent water washing step, which is not practical. In addition, when the pH of the solution is 4.0 to 8.5 and is preserved by salting again after this step, the addition amount of the crosslinking agent is reduced by omitting the water washing step and storing directly by salting, and The cross-linking reaction can be completed during salting and storage.
The inorganic salt is used by adjusting the pH by appropriately adding an alkali hydroxide, ammonia or the like to a saturated aqueous solution of sodium chloride, ammonium sulfate, sodium sulfate, sodium phosphate, sodium carbonate or the like. The reaction time for crosslinking varies depending on the crosslinking agent used, but is usually 1 minute to 120 minutes. After completion of the crosslinking reaction, the solution is desalted by washing with water and used for filling a sausage emulsion.
[0013]
When the adhesive component is a polysaccharide, the polyvalent cation compound such as chitosan, calcium chloride, calcium hydroxide, aluminum sulfate, and alum after directly or after dehydrating and solidifying with a concentrated aqueous solution of inorganic salt such as sodium chloride Alternatively, by appropriately using a polyvalent anionic compound such as sodium alginate or carboxymethylcellulose, dehydration coagulation and coagulation crosslinking can be performed simultaneously. This is also neutralized and washed with water as necessary, and used for filling the sausage emulsion.
[0014]
Instruments used to expand the end of the natural intestine, such as pipes, can be made of plastic, glass, aluminum, stainless steel, rubber tubes, soft plastics, etc. For a regular type, for example, a tapered or non-tapered pipe, for an inflatable type, for example, an elongated rubber balloon, a sausage casing made of plastic or cellulose, etc. It is a thing that can be. The vacuum suction means is, for example, a tube-like structure in which a double tube comprising a breathable inner tube and a non-breathable outer tube is kept under reduced pressure, and the end portion of the natural intestine is placed in the inner tube. It is a method of spreading to.
