Description
本発明は、起泡状態とすることによってホイップドクリームとして使用される油脂組成物とそれを用いた起泡性水中油型乳化油脂組成物およびホイップドクリームに関する。 TECHNICAL FIELD The present invention relates to an oil and fat composition used as a whipped cream by bringing it into a foamed state, a foamable oil-in-water emulsified oil and fat composition using the same, and a whipped cream.
従来より、ナッペ、サンド、トッピング等の食品の各種用途にホイップドクリームが使用されている。ホイップドクリームには、使用用途に応じて、ホイップ後やナッペや注入等の二次加工後に経時的にクリームが硬くなっていく現象（シマリ）や、反対にクリームが軟らかくなっていく現象（モドリ）が調整された硬さ特性が要求される。 Conventionally, whipped cream has been used for various uses of food such as nappe, sand, and topping. Depending on the intended use, whipped cream is a phenomenon that the cream becomes harder with time after whipped or after secondary processing such as nappe and injection (simari), and conversely, the cream becomes softer (modori). ) Adjusted hardness characteristics are required.
特に、多くのクリームをナッペまたは注入するロールケーキ等のサンド用途で使用する場合には、ホイップ後のクリームがナッペまたは注入しやすい程度に硬さが調整されていることだけでなく、切断の際にロールケーキが潰れることなく、クリームがカッターや包丁等に付着しない程度の硬さであることが求められる。また、これらの塗り易さや切断し易さといった作業性に加えて、冷蔵保管中にはクリームの硬さが変化しにくいことが望まれている。 Especially when used in sand applications such as roll cakes where many creams are nappe or poured, not only is the hardness of the cream after whipped adjusted so that it can be easily napped or poured, but also when cutting. In addition, it is required that the roll cake is not crushed and the hardness is such that the cream does not adhere to a cutter or a knife. Further, in addition to the workability such as the ease of application and the ease of cutting, it is desired that the hardness of the cream does not easily change during cold storage.
そこで、これまでにも、ラウリン系油脂や液状油脂等の油脂成分を種々の組み合わせで配合することによって、所望の特性を備えた油脂組成物が提案されている。例えば、近年の消費者の健康志向を踏まえてトランス脂肪酸の循環器系へ及ぼす悪影響を懸念し、トランス脂肪酸の含有量を低減もしくは実質的に含まない組成としつつ、乳化安定性やホイップ性、ホイップ後のクリームの物性が良好な水中油型乳化物、油脂組成物が提案されている（特許文献１〜３）。また、油脂分の割合を抑えつつ、ホイップ後のクリームのシマリを抑制し、クリームの粘度上昇（ボテ）耐性や生産性に優れた起泡性水中油型乳化物が提案されている（特許文献４）。 Therefore, up to now, there have been proposed oil and fat compositions having desired characteristics by blending oil and fat components such as lauric oil and fat and liquid oil and fat in various combinations. For example, in consideration of the recent health consciousness of consumers, there is concern about the adverse effects of trans fatty acids on the circulatory system. Oil-in-water emulsions and oil compositions having good physical properties of the subsequent cream have been proposed (Patent Documents 1 to 3). Further, a foaming oil-in-water emulsion that suppresses creaminess after whipped while suppressing the proportion of oils and fats, and has excellent resistance to viscosity increase (bottom) of cream and productivity is proposed (Patent Document 4).
さらに、流通時の温度条件や温度変化による影響を抑制する観点（特許文献５、特許文献６）や、油脂固化剤の添加により硬さを自在に調整する観点（特許文献７）からのアプローチも提案されている。 Furthermore, there is also an approach from the viewpoint of suppressing the influence of temperature conditions and temperature changes during distribution (Patent Documents 5 and 6) and the viewpoint of freely adjusting the hardness by adding a fat and oil solidifying agent (Patent Document 7). Proposed.
そして、ホイップ開始時の温度条件の変化があってもホイップ時間や含気率などが変化しにくいものとする観点からも、ホイップドクリーム用起泡性水中油型乳化油脂組成物が提案されている（特許文献８）。 Then, even from the viewpoint that the whipped time and the air content are unlikely to change even if there is a change in the temperature condition at the start of whipped, a foamable oil-in-water emulsion oil/fat composition for whipped cream has been proposed. (Patent Document 8).
しかしながら、従来の油脂組成物では、ホイップ後のクリームのシマリを抑制することに主眼を置いて硬化処理やエステル交換処理がされたラウリン系油脂が用いられていたが、ホイップ後から短時間のうちに硬さ変化（シマリ）を得るといったアプローチはなされていなかった。そのため、ホイップ後のクリームの硬さが十分ではなく、特にロールケーキ等のサンド用に用いた場合、切断の際にロールケーキが潰れてしまったり、クリームがカッターや包丁等に付着して切断しにくい傾向にあった。また、冷蔵保管中にシマリの傾向が現れ、口当たりが低下したり、特に、液状油脂と組み合わせた場合には、モドリの傾向が現れ、保形性が低下してしまう等の問題点が懸念されていた。 However, in the conventional oil and fat composition, a laurin-based oil and fat which has been subjected to a hardening treatment or a transesterification treatment with a focus on suppressing the simulation of the cream after the whipped, is used in a short time after the whipped. No approach was taken to obtain hardness changes (similar). Therefore, the hardness of the cream after whipped is not sufficient, especially when it is used for sand such as roll cake, the roll cake will be crushed during cutting, or the cream will stick to the cutter or knife and cut. It tended to be difficult. In addition, there is a concern that a tendency of simulification appears during refrigerated storage, mouthfeel is reduced, and especially when combined with liquid oil and fat, a tendency of foaming appears and shape retention deteriorates. Was there.
このため、これまでの様々な改良の試みにもかかわらず、依然として、ホイップドクリームとした際に良好な硬さ特性を有する油脂組成物が求められていた。 Therefore, in spite of various attempts to improve the oil and fat composition, there is still a demand for an oil and fat composition having good hardness characteristics when it is made into a whipped cream.
本発明は、以上のとおりの事情に鑑みてなされたものであり、ホイップ後から塗り易さや切断し易さ等の作業性が良好である硬さに短時間で変化するとともに、その後、冷蔵保管中には硬さが変化しにくいホイップドクリームとして使用される油脂組成物とそれを用いた起泡性水中油型乳化油脂組成物およびホイップドクリームを提供することを課題としている。 The present invention has been made in view of the circumstances as described above, and changes in hardness in a short time after whipped such that workability such as ease of coating and ease of cutting is good, and then stored in a refrigerator. It is an object of the present invention to provide an oil/fat composition which is used as a whipped cream whose hardness does not easily change, a foamable oil-in-water emulsified oil/fat composition using the same, and a whipped cream.
本発明者らは、上記の課題を解決するために鋭意検討した結果、ラウリン系油脂としてエステル交換処理も硬化処理もされていないものを配合し、油脂組成物中における全構成脂肪酸中のオレイン酸含有量およびＳＦＣに着目して油脂の種類やその組み合わせを精査することによって、ホイップドクリームのシマリ・モドリを調整することが可能となることを見出し、本発明を完成するに至った。 The present inventors, as a result of intensive studies to solve the above problems, as a lauric oil and fat blended those that have not been subjected to transesterification or curing treatment, oleic acid in all the constituent fatty acids in the oil composition The present invention has been completed by discovering that it is possible to adjust Simari-Modori of whipped cream by scrutinizing the types of fats and oils and their combinations by paying attention to the content and SFC.

It is characterized in that the oleic acid content in all the constituent fatty acids in the oil and fat composition is 21 to 30% by mass, and the difference between the SFC at 5°C and the SFC at 15°C is 10 to 30%. ..

本発明の油脂組成物における上記（１）、（２）の油脂の含有量は、油脂組成物全量に対して１５〜６０質量％が好ましく、２５〜５５質量％がより好ましく、３０〜５０質量％がさらに好ましい。 15-60 mass% is preferable with respect to the total amount of oil-fat composition, and, as for content of the oil-fat of said (1) and (2) in the oil-fat composition of this invention, 25-55 mass% is more preferable, 30-50 mass. % Is more preferable.
本発明の油脂組成物は、液状油脂を含有する。液状油脂は、一般に、５℃で流動状を呈し、ヨウ素価が６０以上、好ましくは８０以上である。ホイップ後や二次加工後の冷蔵保管中における硬さ変化を抑制する観点からは、本発明で用いられる液状油脂の全構成脂肪酸中におけるオレイン酸の含有量は、４０質量％以上が好ましく、４５質量％以上がより好ましく、５０質量％以上がさらに好ましい。油脂組成物全体の構成脂肪酸中のオレイン酸含有量を調整しやすいという観点からは、６５質量％以下が好ましい。 The oil/fat composition of the present invention contains a liquid oil/fat. Liquid fats and oils generally have a fluid state at 5° C. and an iodine value of 60 or more, preferably 80 or more. From the viewpoint of suppressing the hardness change during cold storage after whipped or after secondary processing, the content of oleic acid in all the constituent fatty acids of the liquid oil used in the present invention is preferably 40 mass% or more, 45 Mass% or more is more preferable and 50 mass% or more is still more preferable. From the viewpoint of easily adjusting the oleic acid content in the constituent fatty acids of the entire oil and fat composition, it is preferably 65% by mass or less.
液状油脂として、具体的には、例えば、ナタネ油（キャノーラ油等）、米油、大豆油、コーン油、綿実油、ヒマワリ油、ゴマ油、オリーブ油などが挙げられる。これらは１種単独で用いてもよく、２種以上を混合して用いてもよい。オレイン酸の含有量等の点では、ナタネ油が好ましい。 Specific examples of liquid oils and fats include rapeseed oil (canola oil and the like), rice oil, soybean oil, corn oil, cottonseed oil, sunflower oil, sesame oil, olive oil and the like. These may be used alone or in combination of two or more. Rapeseed oil is preferable from the viewpoint of the content of oleic acid.
本発明の油脂組成物中における全構成脂肪酸中のオレイン酸含有量は、２１〜３０質量％であり、２２〜３０質量％が好ましく、２２〜２７質量％がより好ましい。なお、油脂組成物中における全構成脂肪酸中のオレイン酸含有量は、ガスクロマトグラフ法（基準油脂分析試験法（社団法人日本油化学会）の「２．４．２．２−２０１３ 脂肪酸組成（ＦＩＤ昇温ガスクロマトグラフ法）」）により測定することができる。 The oleic acid content in all the constituent fatty acids in the oil and fat composition of the present invention is 21 to 30% by mass, preferably 22 to 30% by mass, more preferably 22 to 27% by mass. In addition, the oleic acid content in all the constituent fatty acids in the oil/fat composition is determined by gas chromatography (standard oil/fat analysis test method (Japan Oil Chemists' Society), “2.4.2.2-2013 fatty acid composition (FID It can be measured by the temperature rising gas chromatograph method)").
また、本発明の油脂組成物における５℃のＳＦＣ（固体脂含量）と１５℃のＳＦＣとの差は、１０〜３０％であり、１０〜２５％が好ましい。なお、油脂組成物のＳＦＣは、基準油脂分析試験法(社団法人日本油化学会)の「２．２．９−２００３ 固体脂含量(ＮＭＲ法)」により測定することができる。 Further, the difference between the SFC (solid fat content) at 5°C and the SFC at 15°C in the oil and fat composition of the present invention is 10 to 30%, preferably 10 to 25%. The SFC of the oil/fat composition can be measured by “2.2.9-2003 solid fat content (NMR method)” of the standard oil/fat analysis test method (Japan Oil Chemists' Society).
このように、油脂組成物中における全構成脂肪酸中のオレイン酸含有量および５℃のＳＦＣと１５℃のＳＦＣとの差を設定することによって、ホイップ後直ちにクリームのシマリを惹起し、ホイップ後少なくとも３０分間にわたってナッペや注入しやすい程度の硬さを有するとともに、切断の際にはクリームがカッターや包丁等に付着しない程度に切断し易い硬さであるホイップドクリームとすることができる。さらに、これらの良好な作業性に加えて、ホイップ後や二次加工後の冷蔵保管中において、シマリやモドリといった硬さ変化が起こりにくいホイップドクリームとすることができる。つまり、保形性を損なわない程度の硬さを維持し、冷蔵保管後であっても製造直後と同等の軟らかな口当たりを感じさせる食感が得られる。 In this way, by setting the oleic acid content in all the constituent fatty acids in the oil and fat composition and the difference between the SFC at 5° C. and the SFC at 15° C., the simulant of the cream is induced immediately after the whipped and at least after the whipped. A whipped cream can be obtained which has hardness such that it can be easily injected into a nappe or pouring for 30 minutes, and is so hard that the cream does not adhere to a cutter, a knife or the like at the time of cutting. Further, in addition to these good workability, a whipped cream can be obtained in which the hardness change such as simulant and moduli does not easily occur during cold storage after whipped or after secondary processing. That is, the hardness is maintained to the extent that shape retention is not impaired, and a texture that gives a soft mouth feel similar to that immediately after production even after refrigerated storage is obtained.
油脂組成物中における全構成脂肪酸中のオレイン酸含有量および５℃のＳＦＣと１５℃のＳＦＣとの差が上記の範囲外である場合には、ホイップドクリームとしての所望の硬さ特性が十分に得られない場合がある。具体的には、油脂組成物中における全構成脂肪酸中のオレイン酸含有量が２１質量％未満の場合には、ホイップ後や二次加工後の冷蔵保管中に、硬くなり続け、食感としても口当たりの滑らかさが損なわれる場合がある。また、油脂組成物中における全構成脂肪酸中のオレイン酸含有量が３０質量％を超える場合には、ホイップ後や二次加工後の冷蔵保管中に、モドリ傾向が強くなり保形性が低下する場合がある。そして、５℃のＳＦＣと１５℃のＳＦＣとの差が１０％未満である場合、ホイップ時間が長くなったり、所望のホイップドクリームが得られず作業性が低下する場合がある。５℃のＳＦＣと１５℃のＳＦＣとの差が３０％を超える場合には、二次加工後の冷蔵保管中において硬くなり続け、食感としても口当たりの滑らかさが損なわれる場合がある。 When the oleic acid content in all the constituent fatty acids in the oil and fat composition and the difference between the SFC at 5°C and the SFC at 15°C are out of the above ranges, the desired hardness characteristics as a whipped cream are sufficient. May not be obtained. Specifically, when the oleic acid content in all the constituent fatty acids in the oil and fat composition is less than 21% by mass, the oleic acid content continues to be hard during chilling storage after whipped or after secondary processing, and even as a texture. The smoothness of the mouth may be impaired. Further, when the oleic acid content in all the constituent fatty acids in the oil/fat composition exceeds 30% by mass, the tendency of moduli becomes strong and the shape retention is deteriorated during refrigerated storage after whipping or after secondary processing. There are cases. When the difference between the SFC at 5° C. and the SFC at 15° C. is less than 10%, the whipped time may be long, or the desired whipped cream may not be obtained, and the workability may be deteriorated. When the difference between the SFC at 5° C. and the SFC at 15° C. exceeds 30%, it may continue to be hard during refrigerated storage after secondary processing, and the texture may be unsmooth to the touch.
本発明の油脂組成物では、ホイップ後のクリームのシマリ・モドリを調整し、作業性をより向上させる観点からは、本発明の油脂組成物におけるラウリン系油脂Ａの含有量は、３５〜５０質量％であることが好ましく、また、液状油脂の含有量は、１０〜２５質量％であることが好ましい。 In the oil and fat composition of the present invention, the content of the lauric oil and fat A in the oil and fat composition of the present invention is 35 to 50 mass from the viewpoint of adjusting the simulant/modori of the cream after whipped and further improving the workability. %, and the content of the liquid oil/fat is preferably 10 to 25% by mass.
ラウリン系油脂Ａの含有量が５０質量％以内の場合や、液状油脂の含有量が１０質量％以上の場合には、ホイップ後のクリームに対し、ある程度のシマリを持たせつつ、シマリ続けるのを抑制することができる。また、ラウリン系油脂Ａの含有量が３５質量％以上の場合や、液状油脂の含有量が２５質量％以内の場合には、ホイップ後のクリームのモドリ傾向が強くなるのを抑制することができる。 When the content of lauric oil and fat A is within 50% by mass or when the content of liquid oil and fat is 10% by mass or more, the cream after whipped has a certain amount of summary, and it is necessary to continue the summary. Can be suppressed. In addition, when the content of the lauric oil and fat A is 35% by mass or more, or when the content of the liquid oil and fat is 25% by mass or less, it is possible to suppress the tendency of the cream after whipped to become modri. ..
また、本発明の油脂組成物では、ホイップ後や二次加工後の冷蔵保管中における保形性をより向上させる観点からは、油脂組成物におけるラウリン系油脂Ａと液状油脂との含有質量比（ラウリン系油脂Ａ／液状油脂）は、１．７〜２．５であることが好ましい。 Moreover, in the oil/fat composition of the present invention, from the viewpoint of further improving the shape retention during refrigeration storage after whipped or after secondary processing, the content ratio by mass of the lauric oil/fat A and the liquid oil/fat in the oil/fat composition ( The lauric oil/fat A/liquid oil/fat) is preferably 1.7 to 2.5.
ラウリン系油脂Ａと液状油脂との含有質量比が上記の範囲内である場合には、ホイップ後や二次加工後の冷蔵保管中における保形性が低下するのを抑制することができる。 When the content mass ratio of the lauric oil and fat A to the liquid oil and fat is within the above range, it is possible to suppress the deterioration of the shape retention property during refrigerated storage after whipped or after secondary processing.
