Abstract
Description
本発明は、ベーカリー用油脂組成物に関する。 The present invention relates to an oil and fat composition for bakery.
パン類に代表されるベーカリー製品は、一般的に、仕込み−混捏−発酵−ベンチ−成形−ホイロ−焼成等の工程を経て製造される。市場に出回るパン類の大部分は、工場の製造ラインで大量生産されたものであるが、このような大量生産方式では、パン生地に対する機械的負荷が大きいために生地に損傷が生じやすく、パンの品質が制約される。通常、パン類の品質はソフト感やしっとり感、口解け感や歯切れの良さ、あるいは風味といった観点から評価されるが、このようなパンの品質には、特に、発酵、成形工程での生地物性が大きく影響する。そのため、パン生地の物性を改良するための生地改良剤が開発されてきている。 Bakery products typified by breads are generally produced through processes such as charging, kneading, fermentation, bench, molding, proofing and baking. Most of the breads on the market are mass-produced on the factory production line, but in such a mass-production system, the mechanical load on the dough is large and the dough is easily damaged. Quality is limited. Usually, the quality of breads is evaluated from the viewpoints of softness, moistness, softness, crispness, and flavor, but the quality of such breads is especially characterized by the physical properties of the dough during fermentation and forming processes. Greatly affects. Therefore, dough improving agents for improving the physical properties of bread dough have been developed.
現在、上記の生地改良剤として、モノアシルグリセロール、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、レシチン等を含有する乳化組成物が広く用いられている。
上記モノアシルグリセロールは、生地の泡（気泡）を安定化する作用があることが知られている。また、小麦粉の澱粉と複合体を形成することで生地の機械への付着を抑制してパン製造の効率化に寄与すると同時に、焼成後のパンにおいて澱粉の老化を防ぐことも知られている（特許文献１、２参照）。
また、コハク酸モノアシルグリセロールやジアセチル酒石酸モノアシルグ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てグルテンネットワークを緻密化し、生地の進展性が向上することが知られている（特許文献３、４参照）。
Currently, emulsified compositions containing monoacylglycerol, organic acid monoacylglycerol, stearoyl calcium lactate, lecithin and the like are widely used as the dough improving agent.
The monoacylglycerol is known to have an effect of stabilizing the foam (bubbles) of the dough. It is also known to prevent the aging of starch in the baked bread at the same time as it contributes to the efficiency of bread production by suppressing the adhesion of the dough to the machine by forming a complex with the starch of wheat flour ( (See Patent Documents 1 and 2).
In addition, organic acid monoacylglycerols such as monoacylglycerol succinate and monoacylglycerol diacetyltartrate are known to act on gluten in wheat flour to densify the gluten network and improve the progress of dough ( (See Patent Documents 3 and 4).
モノアシルグリセロールは、液晶状態（ニート相）で使用するとよりソフトなパンが焼き上がることが知られているが、パン製造の作業環境温度（２０〜４０℃程度）で容易に結晶化してしまう。結晶化したモノアシルグリセロールを含む製剤は生地に馴染みにくいだけでなく、生地中の気泡を安定化することができない。したがって、発酵時や焼成時に生地のボリュームの低下を招きやすく、製造されるパンの品質の向上が制約される。このような問題を回避するために、トリアシルグリセロール、ジアシルグリセロール、モノアシルグリセロール、ステアロイル乳酸塩、及びリン脂質を特定量含有する油相と、糖を特定量含有する水相を特定比で組み合わせて乳化油脂組成物とし、これをパン生地に配合することにより、パン生地の発酵時や焼成後にボリュームが向上し、生地伸展性や機械耐性が良く、焼成後のパンの食感向上、老化防止を図ることも報告されているが（特許文献５参照）、これを用いて製造したパンの品質は未だ十分とはいえない。 Monoacylglycerol is known to bake a softer bread when used in a liquid crystal state (neat phase), but easily crystallizes at the working environment temperature (about 20-40 ° C.) of bread production. A preparation containing crystallized monoacylglycerol is not only difficult to adapt to the dough but also cannot stabilize the bubbles in the dough. Therefore, the volume of the dough is likely to be reduced during fermentation or baking, and the improvement of the quality of the produced bread is restricted. In order to avoid such problems, an oil phase containing a specific amount of triacylglycerol, diacylglycerol, monoacylglycerol, stearoyl lactate and phospholipid and an aqueous phase containing a specific amount of sugar are combined in a specific ratio. The emulsified oil and fat composition is blended into bread dough to increase the volume during fermentation and after baking of the bread dough, with good dough extensibility and mechanical resistance, and to improve the texture of bread after baking and prevent aging This has been reported (see Patent Document 5), but the quality of bread produced using this is still not sufficient.
本発明は、生地に練りこむことで品質に優れたベーカリー製品を焼き上げることができる乳化組成物に用いられうる油脂組成物を提供することを課題とする。 This invention makes it a subject to provide the fats and oils composition which can be used for the emulsion composition which can bake the bakery product excellent in quality by knead | mixing to dough.
本発明者等は上記課題に鑑み、鋭意検討を行った結果、モノアシルグリセロールと、ジアシルグリセロールと、ヒドロキシ酸と脂肪酸とのモノエステル化合物とを所定量含有し、かつシス不飽和モノアシルグリセロールの含有量が、該ヒドロキシ酸と脂肪酸とのモノエステル化合物の含有量に対して質量比（シス不飽和モノアシルグリセロール／ヒドロキシ酸と脂肪酸とのモノエステル化合物）で０．０５〜０．５である油脂組成物を用いて調製した乳化組成物が、生地の成形性を向上させる効果があり、また、この生地を用いることでソフト感、しっとり感、口解け感、歯切れ及び風味のいずれも良好で品質に優れたベーカリー製品が焼き上がることを見い出した。 As a result of intensive studies in view of the above problems, the present inventors have found that monoacylglycerol, diacylglycerol, a monoester compound of a hydroxy acid and a fatty acid is contained in a predetermined amount, and cis unsaturated monoacylglycerol. The content is 0.05 to 0.5 in terms of mass ratio (cis-unsaturated monoacylglycerol / monoester compound of hydroxy acid and fatty acid) with respect to the content of the monoester compound of hydroxy acid and fatty acid. The emulsified composition prepared using the oil and fat composition has the effect of improving the moldability of the dough, and by using this dough, the soft feeling, the moist feeling, the feeling of mouth-breaking, the crispness and the flavor are all good. We found that bakery products with excellent quality were baked.

表５の結果から、ジアシルグリセロールの含有量が低すぎる乳化組成物用いると、パンのしっとり感や口解け感が顕著に悪化すると同時に、生地の成形性（作業性）も顕著に悪化した（比較品５及び６）。さらにヒドロキシ酸と脂肪酸とのモノエステル化合物に対するシス不飽和モノアシルグリセロールの割合が本発明で規定するより低い比較品５においては、風味も著しく劣るものであった。また、ヒドロキシ酸と脂肪酸とのモノエステル化合物に対するシス不飽和モノアシルグリセロールの割合が低すぎたり高すぎたりすると、良好な品質のパンが得られなかった（比較品１〜４、７及び９）。さらに、ジアシルグリセロールの含有量が多すぎると、例えヒドロキシ酸と脂肪酸とのモノエステル化合物に対するシス不飽和モノアシルグリセロールの割合が本発明の範囲内であってもパンの品質が劣っていた（比較品８）。
一方、本発明品１〜１１を用いてパンを製造すると、ソフト感、しっとり感、口解け感、風味及び歯切れ並びに作業性のいずれにおいてもバランスよく良好な評価結果が得られ、その総合得点においても２０点以上と比較品に比べて顕著に高い点数であった。ここで、各評価項目は官能試験の特質上やむを得ず点数で評価しているが、各評価項目における１点の差は実際の感覚で比較すると歴然とした差が認められるものであった。
From the results shown in Table 5, when using an emulsified composition in which the content of diacylglycerol is too low, the feeling of moist bread and the feeling of mouthbreaking deteriorated significantly, and at the same time, the moldability (workability) of the dough also deteriorated significantly (comparison) Articles 5 and 6). Further, in the comparative product 5 in which the ratio of the cis-unsaturated monoacylglycerol to the monoester compound of hydroxy acid and fatty acid was lower than that defined in the present invention, the flavor was also significantly inferior. Moreover, when the ratio of the cis unsaturated monoacylglycerol with respect to the monoester compound of a hydroxy acid and a fatty acid was too low or too high, a bread of good quality could not be obtained (Comparative products 1-4, 7 and 9). . Furthermore, if the content of diacylglycerol was too high, the quality of bread was inferior even if the ratio of cis-unsaturated monoacylglycerol to the monoester compound of hydroxy acid and fatty acid was within the scope of the present invention (comparison) Product 8).
On the other hand, when bread is produced using the products 1 to 11 of the present invention, good evaluation results are obtained in a well-balanced manner in any of soft feeling, moist feeling, mouth-feeling, flavor and crispness, and workability, and in the overall score Was 20 points or more, which was a significantly higher score than the comparative product. Here, each evaluation item is inevitably evaluated by a score because of the nature of the sensory test, but a difference of one point in each evaluation item is a clear difference when compared with an actual sense.
