Description

【0001】
【発明の属する技術分野】
本発明は、耐酸性水中油型乳化組成物及びそれを用いたゲル状食品に関する。更に詳しくは低pHゲル状食品に用いるのに好適な耐酸性水中油型乳化組成物に関し、さらに該耐酸性水中油型乳化組成物を配合してなる酸性ゲル状食品に関する。
【0002】
【従来の技術】
近年、ヨーグルトや乳感を付与したゲル状食品は、油脂や乳蛋白による呈味が優れていることから、食の多様化に適したデザートとして位置付けられている。しかしながら、乳類を含有する酸性のゲル状食品を作る場合、乳類に含まれる蛋白質が酸により凝集して不溶化し均一なゲルを作ることが難しい。更に衛生面からゲル状食品を容器に充填した後に湯殺菌が行われる。その際には、凝集や、分離等の現象が顕著になり均一な好ましいゲル状態が得られない。そのため商品価値を低下させてしまう課題を抱えていた。この課題を解決するために従来技術としてゲル状食品を作る際に温度を十分に下げ、乳成分を最後に加え速やかにゲル化する方法がとられていたが前述の湯殺菌に耐えることはできない。
また、特開昭54−52756号公報(特許文献1)には、酸性物質とアニオン性水性コロイド及び又はこれらに重合リン酸塩を均質混合した蛋白質系酸性食品の沈殿防止剤が開示されている。しかし、この技術では、アニオン性水性コロイドとしてCMCやペクチンを用いるので口溶けが悪くなる問題があり、且つ酸性ゲル状食品の湯殺菌に耐える熱安定性が付与できない。
【0003】
また、特開昭60−210955号公報(特許文献2)には、コロイド性高分子及びショ糖脂肪酸エステル存在させpHを3.7〜4.4のゲル状食品が開示されているが、HMペクチンによる口溶けが悪化する問題がある。
またさらに、特開平8−298942(特許文献3)には、乳蛋白含有物を配合された酸性ゲル状食品の製造において、容器容積の1.1容量%以上のヘッドスペースを有するように充填し、冷却中に振動又は回転処理する方法が開示されているが、湯殺菌に耐えられる製造方法ではあるがゲル化温度の管理や特殊な製造設備が必要であり一般的ではない。
したがって、低pHゲル状食品において良好な乳感を付与し且つ凝集物が発生しない均一なゲル状態を得ることができ、更に湯殺菌処理を行っても分離等の状態悪化が起こらない素材が求められている。

【発明が解決しようとする課題】
本発明の目的は、低pHゲル状食品において良好な乳感と蛋白質の凝集を防止し均一なゲル状食品を作ることができ、更に低pHゲル状食品を湯殺菌処理しても分離などの状態に悪化しない耐酸性水中油型乳化組成物及びそれを用いたゲル状食品を提供することにある。
【0006】
【課題を解決するための手段】
本発明者は、問題点を解決するために鋭意研究した結果、油脂とホエー蛋白及び有機酸モノグリを特定量含む水中油型乳化組成物を得て、それを用いる低pHゲル状食品が、均一なゲルを形成し、良好な乳感を呈し、且つ湯殺菌処理を行っても蛋白質の凝集物が発生しない優れた熱安定性の低pHゲル状食品となることの知見を得て、本発明を完成するに至った。
すなわち本発明は、以下の(1)〜(5)である。
(1)油脂(A)20〜50重量%、ホエー蛋白質(B)0.5〜5.0重量%、有機酸モノグリ(C)1.0〜5.0重量%からなる耐酸性水中油型乳化組成物。
(2)さらに、クエン酸、リンゴ酸、コハク酸、乳酸、リン酸及びこれら塩類からなる群より選ばれるpH調整剤(D)の1種又は2種以上を用いてpH5.0〜5.8に調整することを特徴とする前記の(1)に記載の耐酸性水中油型乳化組成物。
(3)有機酸モノグリがコハク酸グリセリンステアリン酸、クエン酸グリセリンステアリン酸、乳酸グリセリンステアリン酸から選ばれる1種又は2種以上であり、且つHLB値が8.0以上の有機酸モノグリが有機酸モノグリ中60重量%以上となるように配合することを特徴とする前記の(1)または(2)に記載の耐酸性水中油型乳化組成物。
【0007】
(4)増粘多糖類、ゼラチン等のゲル化剤を配合してなるゲル状食品において、前記の(1)〜(3)に記載の耐酸性水中油型乳化組成物をゲル状食品中5〜40重量%配合し、pHを3.0〜4.2に調整することを特徴とするゲル状食品。
(5)次の工程I〜IIIを行うことを特徴とする酸性ゲル状食品の製造方法。
工程I;油脂(A)20〜50重量%、ホエー蛋白質(B)0.5〜5.0重量%、有機酸モノグリ(C)1.0〜5.0重量%を主成分として乳化分散し、耐酸性水中油型乳化組成物を製造する。
工程II;前記の工程Iで得られた耐酸性水中油型乳化組成物を5〜40重量部と、増粘多糖類、蛋白質等のゲル化剤を0.5〜3重量部、水40〜90重量部、糖類0〜30重量部、pH調整剤を配合してpHを3.0〜4.2に調整して酸性ゲル状食品を製造する。
工程III;前記の工程IIで製造した酸性ゲル状食品を容器に詰め、湯中殺菌を行う。
【0008】
【発明実施の形態】
本発明の耐酸性水中油型乳化組成物は、油脂(A)、ホエー蛋白質(B)、有機酸モノグリ(C)から成る水中油型乳化組成物であって、油脂20〜50重量%、ホエー蛋白質0.5〜5.0重量%、有機酸モノグリ1.0〜5.0重量%からなることを特徴とする。ここで有機酸モノグリは有機酸モノグリセリン脂肪酸エステルを意味する。
本発明で用いる油脂(A)としては、食品用に一般的に使用されるものが使用可能であり、具体的には例えば、コーン油、菜種油、大豆油、パーム油、ヤシ油等の植物性油脂;乳脂、豚脂、牛脂及び魚油等の動物性油脂;及びこれら油脂を水素添加したもの、分別したもの、エステル交換したものも使用可能である。本発明の目的であるゲル状食品への乳感や白さを付与するために油脂トータルとしての上昇融点が28℃〜38℃の油脂を用いることが望ましい。融点が低すぎると常温でのゲル状食品の白さが劣り、また経時的に油脂がゲル状食品の表面に流出してくる可能性があり好ましくない。また油脂の融点が高すぎると、食した場合の食感が悪くなり好ましくない。
本発明の耐酸性水中油型乳化組成物中における油脂の含有量は、20〜50重量%であり、20重量%未満ではゲル状食品の乳感が不足し、50重量%よりも多い場合には水中油型乳化組成物の良好な乳化状態を保つことができないためゲル状食品の組織が脆くなりゲル強度等も不十分となる。
【0009】
本発明に用いるホエー蛋白(B)は、その種類に特に限定されるものではない。ホエー蛋白としては、例えば、(i)チーズ製造時に得られるチーズホエー蛋白の濃縮物(ii)カゼイン製造時に得られるホエー蛋白濃縮物、及び(iii)これらを分離精製した分離ホエー蛋白が挙げられ、これらのホエー蛋白を1種単独で、又は2種以上を組み合わせて使用することができる。
ホエー蛋白の配合量は、0.5〜5.0重量%であり、0.5重量%未満ではゲル状食品の乳感が不足し、5.0重量%よりも多い配合ではゲル状食品を湯殺菌した際に部分的に凝集物が発生する可能性が高くなる。
【0010】
本発明に用いる有機酸モノグリ(C)としては、例えば、コハク酸グリセリン脂肪酸エステル、クエン酸グリセリン脂肪酸エステル、乳酸グリセリン脂肪酸エステル、酒石酸グリセリン脂肪酸エステル、酢酸グリセリン脂肪酸エステル等が挙げられる。具体的には例えば、コハク酸グリセリンステアリン酸、コハク酸グリセリンカプリル酸、クエン酸グリセリンステアリン酸、クエン酸グリセリンオレイン酸、乳酸グリセリンステアリン酸、ジアセチル酒石酸グリセリンステアリン酸、アセチル酢酸グリセリンステアリン酸エステル等が挙げられる。
中でもコハク酸グリセリンステアリン酸、クエン酸グリセリンステアリン酸、クエン酸グリセリンオレイン酸が好ましく、更に油脂の構成脂肪酸中の飽和脂肪酸の比率が高いほうが更に好ましい。更に有機酸モノグリのHLB値が8.0以上のものを使用することがより好ましい。
アセチル酢酸グリセリン脂肪酸エステルは酢酸臭が強く、ゲル状食品に酢酸臭が残存する為好ましくない。
有機酸モノグリの配合量は、1.0〜5.0重量%である。その配合量が1.0重量%よりも少ないとゲル状食品に凝集物が発生し易くなり、5.0重量%よりも多い配合では配合量に見合った著しい効果の向上が得られないことに加えて、乳化剤特有のエグ味が発生する。
【0011】
本発明に用いる有機酸モノグリは、コハク酸グリセリンステアリン酸、クエン酸グリセリンステアリン酸、乳酸グリセリンステアリン酸等から選ばれる1種又は2種以上を用いることにより、ゲル状食品を湯殺菌する場合でも凝集物が発生しなくなり、さらに耐酸耐熱性を高めることができる。且つHLB値が8.0以上の有機酸モノグリが有機酸モノグリ中60重量%以上となるように配合することが好ましい。HLB値が8.0以上の有機酸モノグリを有機酸モノグリ中60重量%以上配合することで、さらに耐酸耐熱性を高める効果がある。
【0012】
本発明に用いられるpH調整剤(D)としては、ハク酸、乳酸、リン酸及びこれら塩類が挙げられる。これらの1種または2種以上を用いて乳化液のpHをpH5.0〜5.8になるように配合される。pHを5.0〜5.8にすることで、ゲル状食品に加えた際の凝集を防止し、且つ本発明の水中油型乳化組成物の乳化安定性を著しく高めることができる。pH5.0よりも低いと水中油型乳化組成物に含まれるホエー蛋白質が経時的に凝集し、乳化安定性が低下する。pHが5.8よりも高いと水中油型乳化組成物の安定性は高まるが酸性ゲル状食品に使用した場合、凝集物が発生し易くなる。
【0013】
また、前記の本発明の水中油型乳化組成物を製造する際には、有機酸モノグリの他に、レシチン、ポリグリセリン脂肪酸エステル、モノグリセリン脂肪酸エステル、ショ糖脂肪酸エステル、ソルビタン脂肪酸エステル、プロピレングリコール脂肪酸エステルを少量併用することもでき、その添加量は0〜0.5重量%、好ましくは0〜0.1重量%である。
さらにまた、本発明の耐酸性水中油型乳化組成物には、発明の効果を損なわない範囲において、その他の成分を配合しても差しつかえない。その他の成分としては、糖質、着色料、香料、酸化防止剤、保存料が挙げられる。
【0014】
次に本発明の耐酸性水中油型乳化組成物の製造方法について説明する。
本発明水中油型乳化組成物は、乳化、殺菌設備など特に限定されないが、例えば、次の方法が挙げられる。
所定量の油脂を加熱し油相とする。水に所定量のホエー蛋白質を加え加温溶解し水相とする。有機酸モノグリはそのHLBにより油相及び/又は水相に加え溶解する。有機酸及びこれら塩類などからなるpH調整剤を加える場合にあっては水相に加える。水相に撹拌しながら油相を加え予備乳化した後、ホモジナイザーを用いて均質化し、次いでプレートなどの熱交換器にて殺菌、冷却し再度ホモジナイザーを用いて乳化状態を整え、10℃程度まで冷却する。
【0015】
このようして得られた水中油型乳化組成物は、耐酸性があり、安定性に優れているので、ゲル状食品、特に果汁や酸味で調整した酸性ゲル状食品に好適に使用できる。
【0016】
次に本発明の耐酸性水中油型乳化組成物を用いて製造する酸性ゲル状食品について説明する。
本発明の耐酸性水中油型乳化組成物は、増粘多糖類、ゼラチン等のゲル化剤を配合してなるゲル状食品中に5〜40重量%配合され、pHを3.0〜4.2に調整して用いられる。
ここで酸性ゲル状食品の酸性は、pH3.0〜4.2を意味する。
本発明の耐酸性水中油型乳化組成物の配合率がゲル状食品中5重量%未満では乳感が不足する。乳化組成物の配合率が40重量%を超える配合ではゲル組織が弱くなり離水などの問題が発生し、ゲル組織を高める為にゲル化剤の配合率を高めれば口溶けが悪化する。
【0017】
本ゲル状食品に使用されるゲル化剤は、寒天、ゼラチン、ローカストビーンガム、キサンタンガム、タマリンドシードガム、カラヤガム、ペクチン、カラギーナンなどの多糖類、蛋白質を用いることができる。特に蛋白質やミネラルとの反応性が高いペクチン、カラギーナンを多く配合することは、ゲル状態が不均一になりやすく好ましくなく、ペクチン、カラギーナンの配合率は、ゲル化剤中10重量%以下が好ましい。
【0018】
本ゲル状食品のpHは3.0〜4.2に調整され、pH調整剤としては、例えば、クエン酸、リンゴ酸、乳酸、リン酸、果汁などの酸性成分と、これら塩類からなるアルカリ成分を配合することができ、その種類は限定されない。好ましくはpHをより安定化するために酸性成分とアルカリ成分を併用することがより好ましい。
pHが3.0未満では酸味が強く風味的にも好ましくないが、湯殺菌処理を行った場合、含まれる蛋白質が凝集し易くなり好ましくない。pHが4.2を超える場合でも本発明耐酸性水中油型乳化組成物を用いることができる。しかし、酸性サイドでない一般的な乳製品や乳及び乳製品を主要原料とする食品を用いた場合でも分離の少ないゲル状食品を得ることができるので、本発明の耐酸性水中油型乳化組成物の目的や効果が発揮できない。
また、ゲル状食品の風味調整をする為に、砂糖、シロップ、甘味料、香料、着色料などを用いることもできる。
【0019】
本発明の耐酸性水中油型乳化組成物を用いたゲル状食品の製造方法は、一般的なゼリーなどに代表される製造方法に準じて製造することができ、特には限定はされない。具体的には例えば、適当量の水と本発明の耐酸性水中油型乳化組成物を混ぜ合わせグラニュー糖、ゲル化剤を加え加熱溶解した後、適度に冷却し、次いでpH調整した後に容器に充填され冷却固化してゲル状食品が製造される。湯殺菌する場合においては充填後85℃程度のお湯に必要時間浸して殺菌される。
【0020】
【発明の効果】
本発明の耐酸性水中油型乳化組成物は、優れた耐酸性と耐熱性を有するので、酸性ゲル状食品等に好適に使用できる。
すなわち、前記の乳化組成物をゼリーなどの低pHゲル状食品に加えることにより、蛋白質の凝集や分離などが発生せず均一なゲルを形成することができる。従って、前記の乳化組成物を含有するゲル状食品は、酸性で、良好な乳感と呈味性を有し、さらに湯等の加熱滅菌する場合にも凝集や分離することがない安定なゲルとすることができる。

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to an acid-resistant oil-in-water emulsion composition and a gel food using the same. More specifically, the present invention relates to an acid-resistant oil-in-water emulsion composition suitable for use in low-pH gel foods, and further relates to an acidic gel food prepared by blending the acid-resistant oil-in-water emulsion composition.

[Prior art]
In recent years, yogurt and gel foods with a milky feeling have been positioned as desserts suitable for diversification of foods because of their excellent taste with oils and fats and milk proteins. However, when producing an acidic gel food containing milk, it is difficult to produce a uniform gel because proteins contained in milk are coagulated and insolubilized by acid. Further, from the viewpoint of hygiene, hot water sterilization is performed after filling the gel food into the container. At that time, phenomena such as aggregation and separation become remarkable, and a uniform and preferable gel state cannot be obtained. Therefore, there was a problem that the product value was reduced. In order to solve this problem, as a conventional technique, when making a gel food, the temperature was sufficiently lowered, and a method of rapidly adding the milk component and gelling was taken, but it was unable to withstand the aforementioned hot water sterilization. .
JP-A-54-52756 (Patent Document 1) discloses an acid substance and an anionic aqueous colloid and / or a precipitation inhibitor for a protein-based acidic food in which a homogenous mixture of a polymerized phosphate with them is disclosed. . However, in this technique, since CMC or pectin is used as the anionic aqueous colloid, there is a problem that the dissolution in the mouth deteriorates, and heat stability that resists sterilization of acidic gel foods with hot water cannot be imparted.
[0003]
JP-A-60-210955 (Patent Document 2) discloses a gel food having a pH of 3.7 to 4.4 in the presence of a colloidal polymer and a sucrose fatty acid ester. There is a problem that the dissolution of the mouth by pectin becomes worse.
Further, Japanese Patent Application Laid-Open No. 8-298942 (Patent Document 3) discloses that, in the production of an acidic gel food containing a milk protein-containing substance, filling is carried out so as to have a head space of 1.1% by volume or more of the container volume. Although a method of vibrating or rotating during cooling is disclosed, it is a manufacturing method that can withstand hot water sterilization, but it is not common because it requires management of gelation temperature and special manufacturing equipment.
Therefore, a low pH gel food that can give a good milky feeling and obtain a uniform gel state free from agglomerates, and a material that does not cause deterioration such as separation even when subjected to hot water sterilization treatment is required. Have been.

Specifically, for example, vegetable oils such as corn oil, rapeseed oil, soybean oil, palm oil, coconut oil and the like can be used. Fats and oils; animal fats and oils such as milk fat, lard, beef tallow and fish oil; and hydrogenated, fractionated and transesterified fats and oils can also be used. In order to impart a milky feeling and whiteness to the gel food which is the object of the present invention, it is desirable to use fats and oils having a rising melting point of 28 ° C to 38 ° C as a total fat and oil. When the melting point is too low, the whiteness of the gelled food at normal temperature is poor, and the fats and oils may flow out to the surface of the gelled food over time, which is not preferable. On the other hand, if the melting point of the fat or oil is too high, the texture when eaten is unfavorably deteriorated.
The content of oils and fats in the acid-resistant oil-in-water emulsion composition of the present invention is 20 to 50% by weight, and if it is less than 20% by weight, the milky feeling of the gel food is insufficient, and if it is more than 50% by weight. Cannot maintain a good emulsified state of the oil-in-water emulsion composition, so that the structure of the gel food becomes brittle and the gel strength becomes insufficient.
[0009]
The type of whey protein (B) used in the present invention is not particularly limited. Examples of the whey protein include (i) a concentrate of cheese whey protein obtained at the time of producing cheese, (ii) a whey protein concentrate obtained at the time of producing casein, and (iii) a separated whey protein obtained by separating and purifying these. These whey proteins can be used alone or in combination of two or more.
The amount of whey protein is 0.5 to 5.0% by weight. If it is less than 0.5% by weight, the milky feeling of the gel food is insufficient. The possibility that agglomerates are partially generated during hot water sterilization increases.
[0010]
Examples of the organic acid monoglyce (C) used in the present invention include glycerin succinate fatty acid ester, glycerin citrate fatty acid ester, glycerin lactate fatty acid ester, glycerin tartrate fatty acid ester, and glycerin acetate fatty acid ester. Specifically, for example, glycerin stearic succinate, glycerin succinate caprylic acid, glycerin stearic acid citrate, glycerin oleic acid citrate, glycerin stearic acid lactate, diacetyltartaric acid glycerin stearic acid, acetyl acetate glycerin stearic acid ester, and the like. Can be
Among these, glycerin succinate stearic acid, glycerin stearic citrate, and glycerin oleate citrate are preferred, and the higher the proportion of saturated fatty acids in the constituent fatty acids of fats and oils, the more preferred. Further, it is more preferable to use an organic acid monoglyce having an HLB value of 8.0 or more.
Acetyl acetate glycerin fatty acid ester is not preferred because it has a strong odor of acetic acid and the acetic acid odor remains in the gel food.
The compounding amount of the organic acid monoglyce is 1.0 to 5.0% by weight. If the amount is less than 1.0% by weight, agglomerates are liable to be formed in the gel food, and if the amount is more than 5.0% by weight, a remarkable effect corresponding to the amount cannot be obtained. In addition, an astringent taste peculiar to the emulsifier is generated.
[0011]
The organic acid monoglycerol used in the present invention is aggregated even when the gel food is sterilized by using one or more kinds selected from glycerin stearic acid succinate, glycerin stearic acid citrate, glycerin stearic acid lactate and the like. No matter is generated, and the acid and heat resistance can be further increased. In addition, it is preferable that the organic acid monoglyce having an HLB value of 8.0 or more is blended so as to be 60% by weight or more in the organic acid monogly. By blending the organic acid monoglyce having an HLB value of 8.0 or more in the organic acid monoglyce in an amount of 60% by weight or more, there is an effect of further increasing the acid-heat resistance.
[0012]
Examples of the pH adjuster (D) used in the present invention include succinic acid, lactic acid, phosphoric acid and salts thereof. One or two or more of these are used to adjust the pH of the emulsion to pH 5.0 to 5.8. By adjusting the pH to 5.0 to 5.8, aggregation when added to the gel food can be prevented, and the emulsion stability of the oil-in-water emulsion composition of the present invention can be significantly increased. When the pH is lower than 5.0, the whey protein contained in the oil-in-water emulsion composition is aggregated with time, and the emulsion stability is reduced. When the pH is higher than 5.8, the stability of the oil-in-water emulsified composition increases, but when it is used for an acidic gel food, aggregates are easily generated.
[0013]
When producing the oil-in-water emulsion composition of the present invention, in addition to the organic acid monoglycemic, lecithin, polyglycerin fatty acid ester, monoglycerin fatty acid ester, sucrose fatty acid ester, sorbitan fatty acid ester, propylene glycol A small amount of a fatty acid ester may be used in combination, and the amount added is 0 to 0.5% by weight, preferably 0 to 0.1% by weight.
Further, other components may be added to the acid-resistant oil-in-water emulsion composition of the present invention as long as the effects of the present invention are not impaired. Other ingredients include carbohydrates, colorants, flavors, antioxidants, and preservatives.
[0014]
Next, the method for producing the acid-resistant oil-in-water emulsion composition of the present invention will be described.
The oil-in-water emulsified composition of the present invention is not particularly limited in terms of emulsification, sterilization equipment, and the like, and examples thereof include the following method.
A predetermined amount of fat or oil is heated to make an oil phase. A predetermined amount of whey protein is added to water and dissolved by heating to obtain an aqueous phase. The organic acid monoglyce is added and dissolved in the oil phase and / or the aqueous phase by its HLB. When adding a pH adjuster composed of an organic acid and salts thereof, it is added to the aqueous phase. The oil phase was added to the aqueous phase while stirring, and the mixture was pre-emulsified. The mixture was homogenized using a homogenizer, then sterilized and cooled using a heat exchanger such as a plate, cooled, and again emulsified using a homogenizer, and cooled to about 10 ° C. I do.
[0015]
The oil-in-water emulsion composition thus obtained has acid resistance and excellent stability, and thus can be suitably used for gel foods, particularly acidic gel foods adjusted with fruit juice or acidity.
[0016]
Next, an acidic gel food produced using the acid-resistant oil-in-water-type emulsified composition of the present invention will be described.
The acid-resistant oil-in-water emulsion composition of the present invention is blended at 5 to 40% by weight in a gel food containing a gelling agent such as a thickening polysaccharide and gelatin, and has a pH of 3.0 to 4.0. Adjusted to 2 and used.
Here, the acidity of the acidic gel food means pH 3.0 to 4.2.
If the compounding ratio of the acid-resistant oil-in-water-type emulsified composition of the present invention is less than 5% by weight in the gel food, milky feeling is insufficient. If the blending ratio of the emulsified composition exceeds 40% by weight, the gel structure is weakened and problems such as water separation occur. If the blending ratio of the gelling agent is increased in order to increase the gel structure, the dissolution in the mouth deteriorates.
[0017]
As a gelling agent used in the present gel food, polysaccharides and proteins such as agar, gelatin, locust bean gum, xanthan gum, tamarind seed gum, karaya gum, pectin, and carrageenan can be used. In particular, it is not preferable to mix a large amount of pectin and carrageenan, which have high reactivity with proteins and minerals, because the gel state tends to be nonuniform, and the mixing ratio of pectin and carrageenan is preferably 10% by weight or less in the gelling agent.
[0018]
The pH of the present gel food is adjusted to 3.0 to 4.2, and as the pH adjuster, for example, an acidic component such as citric acid, malic acid, lactic acid, phosphoric acid, fruit juice, and an alkaline component composed of these salts And the type is not limited. It is more preferable to use an acidic component and an alkaline component together in order to further stabilize the pH.
When the pH is less than 3.0, the acidity is strong and the flavor is not preferable, but when sterilized with hot water, the contained protein is easily aggregated, which is not preferable. Even when the pH exceeds 4.2, the acid-resistant oil-in-water emulsion composition of the present invention can be used. However, even in the case of using a general dairy product that is not an acidic side or a food product containing milk and dairy products as main raw materials, it is possible to obtain a gel food with little separation, so the acid-resistant oil-in-water emulsion composition of the present invention. The purpose and effect of can not be demonstrated.
In addition, sugar, syrup, sweetener, flavor, colorant, and the like can be used to adjust the flavor of the gel food.
[0019]
The method for producing a gel food using the acid-resistant oil-in-water-type emulsified composition of the present invention can be produced according to a production method represented by a general jelly or the like, and is not particularly limited. Specifically, for example, an appropriate amount of water and the acid-resistant oil-in-water-type emulsified composition of the present invention are mixed together, a granulated sugar, a gelling agent is added thereto, and the mixture is heated and dissolved. Filled, cooled and solidified to produce a gel food. In the case of hot water sterilization, after filling, it is immersed in hot water of about 85 ° C. for a required time and sterilized.
[0020]
【The invention's effect】
