In the case of Comparative Example 1, feathering was slightly observed when added to coffee after storage at 5 ° C. for 1 week. From the above, it was confirmed that the use of the soybean emulsified composition provided a rich and savory coffee whitener. *
- Example 2 in which a soybean emulsified composition was blended so that the protein content in the coffee whitener was 0.5%, and Examples 3 to 5 in which the average HLB was adjusted by combining organic acid monoglyceride and polyglycerin fatty acid ester Examples 6 and 7 in which organic acid monoglyceride and sugar ester were combined, and Example 8 in which a soybean emulsified composition was blended in a coffee whitener so as to have a protein content of 2.0% were examined. Examples 2 to 7 were rich, and Example 8 was more rich than Example 1. In all of Examples 2 to 8, there was no blue odor of soybeans, and the flavor was good without losing the flavor of coffee. Examples 3 to 7 had a tendency to increase in viscosity slightly after storage at 5 ° C.
- Examples 2 and 8 also had good emulsion stability. In Examples 2 to 5, 7, and 8, almost no feathering was confirmed. From the above, it was confirmed that regardless of the emulsifier, a soy emulsion composition can be used to prepare a coffee whitener that is rich, flavorful and stable in emulsification. In addition, an emulsifier having an average HLB of 5 or more showed good results for feathering. Considering emulsion stability and feathering, the combination of organic acid monoglyceride and polyglycerin fatty acid ester in the vicinity of average HLB 12.7 showed the best results. *
- Example 9 granulated sugar
- Example 10 super white sugar
- Example 11 maltose
- blending soy emulsified composition provides a coffee whitener that feels richer than conventional coffee whiteners using soymilk or isolated soy protein, and has a good flavor without the blue odor of soybeans. can do.

Abstract
Description
通常の未変性(NSI 90以上)の大豆を原料とした場合ではLPは可溶性の状態で存在するため、水抽出すると水溶性画分側へ抽出される。一方、本発明に用いられる大豆乳化組成物の場合、LPが原料大豆中において加熱処理によって失活され不溶化しているため、不溶性画分側に残る。 蛋白質中におけるLPの割合が高まることによって油脂の乳化状態が安定化されるばかりでなく、グロブリン蛋白質を主体とした通常の大豆蛋白質組成では得られない滑らかな物性の食感を得ることができ、また素材にコクのある風味が付与される。
過度に脱脂され脂質含量が少なすぎると本発明に用いられる脂質に富む大豆乳化組成物を得ることが困難となる。特にヘキサン等の有機溶媒で抽出され、中性脂質の含量が1重量%以下となった脱脂大豆は、大豆の良い風味が損なわれ好ましくない。
そのような加工大豆は、加熱処理やアルコール処理等の加工処理を行って得られる。加工処理の手段は特に限定されないが、例えば乾熱処理、水蒸気処理、過熱水蒸気処理、マイクロ波処理等による加熱処理や、含水エタノール処理、高圧処理、およびこれらの組み合わせ等が利用できる。
例えば過熱水蒸気による加熱処理を行う場合、その処理条件は製造環境にも影響されるため一概に言えないが、おおよそ120~250℃の過熱水蒸気を用いて5~10分の間で加工大豆のNSIが上記範囲となるように処理条件を適宜選択すれば良く、加工処理に特段の困難は要しない。簡便には、NSIが上記範囲に加工された市販の大豆を用いることもできる。
また水抽出の際あるいは水抽出後に解乳化剤を添加して豆乳からの脂質の分離を促進させることも可能であり、解乳化剤は特に限定されないが例えば米国特許第6,548,102号公報に開示されている解乳化剤を使用すればよい。ただし本発明に用いられる大豆乳化組成物を調製する場合は解乳化剤を用いなくとも実施が可能である。
通常の大豆粉や分離大豆蛋白に水、油脂を加えて該大豆乳化組成物と類似の組成の乳化組成物にすることは可能であるが、リポキシゲナーゼ蛋白質含量あるいはLCI値を同等なレベルに調整することは困難である。そして本技術により調製された大豆乳化組成物は、このような組み立て製品に比べて格段に風味が良好であり、食品素材としての利用適性が高いことに特徴を有する。
