Description

明細書 乳化油脂組成物 技術分野  Description Emulsified Oil Composition Technical Field
本発明は、 パン等のベー力リー製品改良用の乳化油脂組成物に関する。 背景技術  The present invention relates to an emulsified oil / fat composition for improving a baker's product such as bread. Background art
通常、 パンの製造工程は、 仕込み一混捏ー発酵一ベンチ一成型一ホイロー焼成 等から構成されており、 焼成後のパンの品質は、 発酵、 成型工程での生地物性や 品質に大きく左右される。 また、 焼成後においては、 パンの品質は経時的に変化 が少ないことも求められている。  Normally, the bread production process consists of a mix of mashing, fermentation, bench, molding, whirling, etc. The quality of the bread after baking is greatly influenced by the physical properties and quality of the dough in the fermentation and molding processes. . In addition, after baking, the quality of bread is required to change little over time.
パン市場においては、 その製造規模は家内的な小規模のものから広域販売を目 的とする大量生産規模まで大小様々であるが、 市場の流通量から大量生産方式が 大きな比重を占めている。 大量生産方式においては、 製造工程中の機械的負荷が 大きいため、 特に前記成型工程において生地の損傷が起こりやすい。 また、 流通 過程を経るために品質に経時変化が生じ易い。  In the bread market, the scale of production varies widely from small-scale households to large-scale production aimed at wide-area sales, but the mass production method occupies a large proportion due to the market distribution volume. In the mass production method, the mechanical load during the manufacturing process is large, and the fabric is easily damaged especially in the molding process. In addition, the quality tends to change over time due to the distribution process.
これら問題点を改善するために、 機械耐性の良いパン生地を調製するための生 地改良剤が使用され、 流通過程の品質維持のために老化防止剤などの改良剤が使 用されている。  In order to remedy these problems, ground improvers are used to prepare bread dough with good mechanical resistance, and improvers such as anti-aging agents are used to maintain the quality of the distribution process.
製パン用の生地改良剤としては、 モノァシルグリセロール、 コハク酸モノァシ ルグリセロール又はジァセチル酒石酸モノァシルグリセロール等の有機酸モノア シルグリセロール、 ステアロイル乳酸カルシウム又はレシチン等の乳化剤が広く 使用されている。 その中でもモノアシルグリセロールは、 小麦粉の損傷澱粉と複 合体を形成し、 その結果、 パン生地の粘着性を抑制し、 機械への付着を少なくす るばかりでなく、 焼成後のパンの澱粉の老化を防止し、 パンの保存性を向上する という効果がある。 そのため、 製パン用の改良剤の主要成分として広く使用され ている (JP-A 2— 1 240 5 2、 JP-A4— 1 97 1 30)。 As dough improving agents for bread making, emulsifiers such as monoacylglycerol, monoacylglycerol succinate or monoacylglycerol diacetyl tartrate, monoacylglycerol, stearoyl calcium lactate or lecithin are widely used. Among them, monoacylglycerol is more complex with damaged starch of wheat flour. As a result, the stickiness of the bread dough is suppressed, and not only the adhesion to the machine is reduced, but also the starch aging after baking is prevented, and the shelf life of the bread is improved. is there. For this reason, it is widely used as the main ingredient of bread improvers (JP-A 2-1 240 5 2 and JP-A4-1 97 1 30).
また、 コハク酸モノアシルグリセロールゃジァセチル酒石酸モノァシルダリセ ロール等の有機酸モノアシルグリセロールは、 小麦粉中のグルテンに作用し、 グ ルテンネットワークが緻密になり、 生地の伸展性が向上するという効果がある。 そのため、 大量生産するために機械化された製パン用の改良剤の主要成分として 使用されている ( JP-A 5— 2 3 6 9 1 9、 JP-A 7— 7 96 8 7 )。  In addition, organic acid monoacylglycerols such as monoacylglycerol succinate and diacetyl monocyldariserol tartrate act on gluten in wheat flour, and the gluten network becomes dense and the dough extensibility is improved. For this reason, it is used as the main component of mechanized bread improvers for mass production (JP-A 5-2 3 6 9 1 9 and JP-A 7-7 96 8 7).
また、 モノアシルグリセロールや有機酸モノァシルグリセロールの製剤として の使い易さや効果を向上させるために粉末化したり (JP-A5 8— 1 5 8 144、 JP-A2002 - 1 1 269 2 )、 水中油型エマルションとしたり (JP-A63— 7 In order to improve the ease of use and effectiveness of monoacylglycerol and organic acid monoacylglycerol, it can be powdered (JP-A5 8-1 5 8 144, JP-A2002-1 1 269 2), Oil-type emulsion (JP-A63— 7
