Description

本発明は品質の良好な発酵乳の製造技術に関するものである。 The present invention relates to a technique for producing fermented milk of good quality.

従来乳を発酵させた発酵乳は、そのカードを破砕する、しないに拘わらず経時で乳漿分離を起こす。特に破砕した場合は蛋白凝集を起こし商品価値を失う。
これを防止するためペクチンとか繊維素グリコール酸ナトリウムを添加するが、分離は防止できても、食感が糊っぽく、かつ味のリリースが良くない為、嗜好性を著しく低下させる。
Fermented milk obtained by fermenting conventional milk causes whey separation over time regardless of whether the curd is crushed or not. Especially when crushed, it causes protein aggregation and loses commercial value.
In order to prevent this, pectin or sodium fibrin glycolate is added, but even if the separation can be prevented, the texture is sticky and the taste release is not good, so the palatability is remarkably lowered.

発酵乳の乳漿分離、蛋白凝集防止に関する技術は当該業界ではペクチンとかCMC(繊維素グリコール酸ナトリウム)が一般的に使用されているが、これらの使用はいずれも糊感がでて風味を阻害し、かつ味のリリースが良くないという欠点を有する。また特開2012−105566に開示されている技術は粒ゼリー入りドリンクヨーグルトには有効な技術であるが、通常の発酵乳では解決できない。 Pectin and CMC (sodium fibrin glycolate) are commonly used in the industry as technologies for whey separation and protein aggregation prevention in fermented milk. And has the disadvantage that the taste release is not good. Moreover, although the technique currently disclosed by Unexamined-Japanese-Patent No. 2012-105566 is an effective technique with drink yogurt containing a grain jelly, it cannot be solved with normal fermented milk.

特開2012-105566号公報JP 2012-105566 A

本発明は発酵乳のカードを破砕しても乳漿分離のない、蛋白凝集のない、糊感のでない味のリリースの良い発酵乳を作ることである。 An object of the present invention is to produce fermented milk having a good taste release without whey separation, no protein aggregation, and no stickiness even when the curd of fermented milk is crushed.

本発明の構成要件は
1. ゲルの成分としてコンニャクマンナンを含有したゲルを調整する。
2. このゲルを破砕、カットする、破砕しない場合は小つぶに成形する。
3. この破砕した、カットした、又は成形したゲルを発酵乳に混入してミックスするが、この混入量は発酵乳とゲルの重量の0.01%以上のコンニャクマンナンを含有させること。
発酵乳に混入するコンニャクマンナン含有ゲルは、ゲル化したものをカット又は/及び破砕して混入するが、カットでも、破砕でも、その効果に変わりはない。またこのゲルに耐熱性をもたせ、シロップ漬けとして容器に詰めて殺菌し、シロップと共に混入してもよく、ゲルとシロップをセパレートしシロップのみを混入しても、ゲルのみを混入しても効果に差はない。
コンニャクマンナンを単体で使用しても、乳漿分離防止効果、蛋白凝集防止効果、味のリリース効果は期待できない。
本発明の作用効果はコンニャクマンナンの成分とゲル化性高分子多糖類の成分の協同作用により、乳安定効果をもたらすものと考えられる。
このコンニャクマンナン含有ゲルは、強く硬いゲルでも良く、又はゾルに近いゲルでも良いので、製品の目的により適宜選択すればよい。
The constituent requirements of the present invention are:
1. Prepare a gel containing konjac mannan as a component of the gel.
2. Crush and cut this gel.
3. This crushed, cut, or shaped gel is mixed in the fermented milk and mixed, but the mixed amount should contain 0.01% or more of the fermented milk and gel by weight of konjac mannan.
The konjac mannan-containing gel mixed in the fermented milk is mixed by cutting or / and crushing the gelled gel, but the effect remains the same whether cut or crushed. In addition, this gel can be heat-resistant, packed in a syrup container, sterilized, and mixed with syrup. Separated gel and syrup, mixed with syrup alone, or mixed with gel alone is effective. There is no difference.
Even if konjac mannan is used alone, it cannot be expected to prevent whey separation, prevent protein aggregation, and release taste.
The effect of the present invention is considered to bring about a milk stabilizing effect by the cooperative action of the konjac mannan component and the gelling polymer polysaccharide component.
The konjac mannan-containing gel may be a strong and hard gel or a gel close to a sol, and may be appropriately selected depending on the purpose of the product.

以下試験例、実施例により説明する。
試験例1 コンニャクマンナンの乳漿分離防止、蛋白凝集防止効果の発現する濃度の試験

比較のために、前記試験において、コンニャク粉を使用しない区を調整し、プレーンヨーグルトに添加混合し、乳漿分離防止効果、蛋白凝集防止効果を判定した。この結果は表1〜表23に記載する。
試験に供したプレーンヨーグルトは森永乳業株式会社製ビフィダスヨーグルトである。
又豆乳を乳酸菌発酵させた豆乳ヨーグルトにおいても、同様の試験をしたが、結果は牛乳製品の場合と同じ結果であった。
試験結果の判定基準は次の通りである。
判定基準: 蛋白凝集は、蛋白凝集なし −、蛋白凝集あり +、やや蛋白凝集あり +−。
乳漿分離は、乳漿分離なし −、乳漿分離あり +、やや乳漿分離あり+−。
味のリリースは、味のリリース良くない −、味のリリース良好 +、味のリリースやや良くない +− 。
The test examples and examples will be described below.
Test Example 1 Test of concentration of konjac mannan to prevent whey separation and protein aggregation preventing effect Carrageenan, gellan gum, agar, gelatin, tamarind seed polysaccharide, xanthan gum, sodium alginate and pectin are each 1% by weight as gelling substances. Konjac powder was prepared in 0.1 and 0.07 weight percent aqueous solutions, heated to 80 ° C., cooled, held for 24 hours, adjusted to sol-gel, and 10% by weight in plain yogurt prepared separately. After adding and mixing, the effect of preventing whey separation, the effect of preventing protein aggregation, and the release of taste were determined.
For comparison, in the test, a section where konjac powder was not used was prepared, and added to and mixed with plain yogurt to determine the effect of preventing whey separation and the effect of preventing protein aggregation. The results are shown in Tables 1 to 23.
The plain yogurt used for the test is Bifidas yogurt manufactured by Morinaga Milk Industry Co., Ltd.
The same test was performed on soymilk yogurt obtained by fermenting soymilk with lactic acid bacteria. The result was the same as that of the milk product.
The criteria for the test results are as follows.
Criteria: Protein aggregation has no protein aggregation −, protein aggregation +, some protein aggregation + −.
For whey separation, there is no whey separation-, with whey separation +, with some whey separation +-.
Taste release is not good taste release-, taste release is good +, taste release is not good +-.
