Description

本発明は、食品改質剤に関する。   The present invention relates to a food modifier.

油脂は、一般に劣化し易く、保存中に食品の外観および風味を著しく損なう原因となる。さらに、生活習慣病の予防、ダイエットなどの観点から、近年、加工食品中に油脂を多量に含むことは敬遠される傾向にある。そのため、加工食品に含まれる油脂量を減少させること、あるいは加工食品に油脂を全く用いないことが検討されている。しかし、加工食品、特に穀粉を主成分とする加工食品において、油脂は、風味、食感、および外観といった食品の本質的な部分に関与しているため、その代替は容易ではない。   Oils and fats are generally easily deteriorated, and cause significant damage to the appearance and flavor of food during storage. Furthermore, from the viewpoints of prevention of lifestyle-related diseases, dieting, and the like, in recent years, it tends to be avoided to include a large amount of fats and oils in processed foods. Therefore, it has been studied to reduce the amount of fats and oils contained in processed foods, or not to use fats and oils in processed foods at all. However, in processed foods, particularly processed foods based on flour, fats and oils are involved in essential parts of the food such as flavor, texture, and appearance, so that replacement is not easy.

ところで、油脂の劣化を防止する観点から、油脂を粉末化することが提案されている。例えば、特許文献1には、液状脂肪油にアルブミンを結合させた粉末が保存安定性に優れていることが記載されている。特許文献2には、含水エタノール5L中に粉末活性グルテン1kgを加えた液1kgに対して、精製脱臭魚油50gを混合して乾燥して得られた油脂粉末が、含水食品中に添加した場合でも安定であることが記載されている。しかし、これらの油脂粉末は、食品中に油脂を含むことを前提としているため、結局、油脂の劣化による加工食品の風味および外観の低下の問題は残る。さらに、これらの油脂粉末を用いても油脂量は変わらないため、生活習慣病の予防、ダイエットなどの問題もある。   By the way, from the viewpoint of preventing deterioration of fats and oils, it has been proposed to powder the fats and oils. For example, Patent Document 1 describes that a powder obtained by binding albumin to liquid fatty oil is excellent in storage stability. Patent Document 2 discloses that even when a fat powder obtained by mixing 50 g of purified deodorized fish oil with 1 kg of a solution obtained by adding 1 kg of powdered active gluten in 5 L of water-containing ethanol is added to the water-containing food. It is described as being stable. However, since these fat powders are premised on containing fats and oils in foodstuffs, the problem of the fall of the flavor and external appearance of processed foods by fat and oil deterioration remains after all. Furthermore, since the amount of fats and oils does not change even if these fats and oils powder are used, there are problems such as prevention of lifestyle-related diseases and dieting.

加工食品の風味、食感、および外観を損なうことなく、含有される油脂を代替できるような食品改質剤が求められている。

There is a need for food modifiers that can replace the fats and oils contained without impairing the flavor, texture, and appearance of processed foods.
JP 63-44844 A Japanese Patent Laid-Open No. 2-155990

本発明の目的は、加工食品、特に穀粉を主成分とする加工食品の風味、食感、および外観を損なうことなく、含有される油脂を代替することが可能な食品改質剤を提供することにある。   An object of the present invention is to provide a food modifier capable of replacing fats and oils contained therein without impairing the flavor, texture, and appearance of processed foods, particularly processed foods mainly composed of flour. It is in.

本発明者らは、生グルテンと、少量の油脂とを混練して乾燥することによって得られる食品改質剤が、加工食品、特に穀粉を主成分とする加工食品中に含有される油脂と代替した場合においても、得られる加工食品の風味、食感、および外観を損なわず、むしろさらに良好な食感(しっとり感、軽い食感など)および外観を付与することができることを見出した。さらにこの食品改質剤を用いることによって、上記加工食品の老化(特に澱粉の老化)を抑制できることを見出して、本発明を完成するに至った。   The present inventors have replaced a food modifier obtained by kneading raw gluten and a small amount of fats and oils and drying them with processed foods, particularly fats and oils contained in processed foods mainly composed of flour. In this case, it has been found that the flavor, texture and appearance of the obtained processed food are not impaired, but rather a better texture (moist feeling, light texture, etc.) and appearance can be imparted. Furthermore, by using this food modifier, it was found that aging of the processed food (especially aging of starch) can be suppressed, and the present invention has been completed.

本発明の食品改質剤は、生グルテン100質量部に対して、油脂5〜8質量部を混練し、乾燥して得られる。   The food modifier of the present invention is obtained by kneading 5 to 8 parts by mass of fats and oils with respect to 100 parts by mass of raw gluten and drying.

ある実施態様においては、上記油脂は、不飽和脂肪酸を50質量%以上含む。   In a certain embodiment, the said fats and oils contain 50 mass% or more of unsaturated fatty acids.

本発明はまた、上記食品改質剤からなる、食品の老化抑制剤を提供する。   The present invention also provides a food aging inhibitor comprising the food modifier.

本発明はまた、穀粉を主成分とする食品を提供し、該食品は、上記食品改質剤を含む。   This invention also provides the foodstuff which has a flour as a main component, and this foodstuff contains the said food modifier.

本発明の食品改質剤は、得られる加工食品、特に穀粉を主成分とする加工食品に対して、良好な食感(しっとり感、軽い食感など)を付与することができる。特に、この食品改質剤は、穀粉を主成分とし、かつ油脂を含む加工食品において、該油脂の一部または全部と代替した場合にも、得られる加工食品の風味、食感、および外観を損なうことなく、さらにふんわりとした外観、および良好な食感(しっとり感、もちもち感、および軽い食感)を付与することができる。さらに得られる加工食品の老化(特に澱粉の老化)を抑制することができる。そのため、本発明の食品改質剤は、特に穀粉を主成分とする加工食品の油脂の代替に有用である。   The food modifier of the present invention can impart a good texture (moist feeling, light texture, etc.) to the obtained processed food, particularly processed food containing flour as a main component. In particular, this food modifier has the flavor, texture and appearance of the obtained processed food even when it is replaced with a part or all of the fat and oil in a processed food containing fat and oil as a main component and flour. Without impairing, a softer appearance and a good texture (moist feeling, sticky feeling, and light texture) can be imparted. Furthermore, aging (especially aging of starch) of the obtained processed food can be suppressed. Therefore, the food modifier of the present invention is particularly useful as a substitute for fats and oils in processed foods mainly composed of flour.

本発明の食品改質剤は、生グルテン100質量部に対して、油脂5〜8質量部を混練し、乾燥して得られる。必要に応じて、その他の成分を含有してもよい。この食品改質剤は、主に穀粉を主成分とする加工食品に用いられる。   The food modifier of the present invention is obtained by kneading 5 to 8 parts by mass of fats and oils with respect to 100 parts by mass of raw gluten and drying. You may contain another component as needed. This food modifier is mainly used for processed foods mainly composed of flour.

(生グルテン)
本発明において、生グルテンとは、例えば、穀類から直接、洗浄法、抽出法などの当業者が通常行う方法によって得られるグルテンのうち、乾燥、粉末化などの処理を受けていないグルテンをいう。この生グルテンは、通常、水分を約60質量%〜70質量%含有する。
(Raw gluten)
In the present invention, raw gluten refers to gluten that has not been subjected to a treatment such as drying or pulverization, among gluten obtained by a method commonly performed by those skilled in the art, such as a washing method and an extraction method, directly from cereals. This raw gluten usually contains about 60% to 70% by weight of water.

本発明に用いられる生グルテンの原料としては、小麦、ライ麦などの穀類が用いられる。好ましくは小麦である。上記穀類には、タンパク質であるグルテンが豊富に含有される。グルテンは、S−S結合を含むため弾力性に富むことが知られており、種々の食品の食感に重要な役割を果たしている。   Grains such as wheat and rye are used as raw gluten materials used in the present invention. Preferably it is wheat. The cereal is rich in gluten, which is a protein. Gluten is known to be rich in elasticity because it contains an S—S bond, and plays an important role in the texture of various foods.

上記洗浄法は、例えば、小麦粉などの穀粉に少量の溶媒(例えば、水)を加えて練った生地(ドウ)を、上記溶媒で洗浄すること、あるいは多量の溶媒中でさらに練ることによって行われる。この方法により、澱粉が溶媒中に懸濁して除去され、グルテンが粘弾性の塊として得られる。上記溶媒としては、通常、水が用いられるが、希リン酸ナトリウム溶液、食塩水などを用いてもよい。   The washing method is performed, for example, by washing a dough made by adding a small amount of solvent (for example, water) to flour such as wheat flour with the above solvent or further kneading in a large amount of solvent. . By this method, starch is suspended and removed in a solvent, and gluten is obtained as a viscoelastic mass. As the solvent, water is usually used, but dilute sodium phosphate solution, saline, and the like may be used.

上記抽出法は、例えば、上記ドウに希酢酸−エタノール混合液などを加えて、グルテンを溶解させ、澱粉を不溶物として分別することによって行われる。   The extraction method is performed, for example, by adding a dilute acetic acid-ethanol mixed solution to the dough to dissolve gluten and fractionating starch as an insoluble matter.

(油脂)
本発明に用いられる油脂は、一般に食品に使用される油脂であればよく、特に制限されない。例えば、サフラワー油、ひまわり油、とうもろこし油、アマニ油、米油、大豆油、綿実油、ごま油、オリーブ油、ヤシ油、パーム油、なたね油などの植物性油脂;豚脂、牛脂、魚油、鯨油などの動物性油脂;またはそれらに水素添加した硬化油などが挙げられる。これらの油脂の中でも、得られる食品改質剤の流動性が良好である点、およびこの食品改質剤を用いた場合に加工食品に優れた保湿性(しっとり感)および老化抑制効果を付与する点から、不飽和脂肪酸を50質量%以上含む油脂(例えば、サフラワー油、ひまわり油、とうもろこし油、アマニ油、米油、大豆油、綿実油などの植物性油脂)を用いることが好ましく、不飽和脂肪酸を70質量%以上含む油脂(例えば、サフラワー油、ひまわり油など)を用いることがより好ましい。油脂は、単独で用いてもよく、2種以上を組み合わせて用いてもよい。
(Oil and fat)
The fats and oils used in the present invention are not particularly limited as long as they are generally used for foods. For example, vegetable oils such as safflower oil, sunflower oil, corn oil, linseed oil, rice oil, soybean oil, cottonseed oil, sesame oil, olive oil, palm oil, palm oil, rapeseed oil; pork fat, beef fat, fish oil, whale oil, etc. Animal fats and oils; or hydrogenated hydrogenated oils. Among these fats and oils, the fluidity of the resulting food modifier is good, and when this food modifier is used, the processed food has excellent moisturizing properties (moist feeling) and an anti-aging effect. In view of this, it is preferable to use oils and fats containing 50% by mass or more of unsaturated fatty acids (for example, vegetable oils such as safflower oil, sunflower oil, corn oil, linseed oil, rice oil, soybean oil, and cottonseed oil). It is more preferable to use fats and oils (for example, safflower oil, sunflower oil, etc.) containing 70% by mass or more of fatty acids. The fats and oils may be used alone or in combination of two or more.

(その他の成分)
本発明の食品改質剤は、本発明の効果を損なわない範囲で、必要に応じて、還元剤(ピロ亜硫酸ナトリウム、ピロ亜硫酸カリウム、アスコルビン酸、アスコルビン酸ナトリウム、グルタチオン、システインなど)、酸化防止剤(ビタミンEなど)などのその他の成分を含有し得る。
(Other ingredients)
The food modifier of the present invention is a reducing agent (sodium pyrosulfite, potassium pyrosulfite, ascorbic acid, sodium ascorbate, glutathione, cysteine, etc.), antioxidant, as necessary, as long as the effects of the present invention are not impaired. Other ingredients such as agents (such as vitamin E) may be included.

(食品改質剤)
本発明の食品改質剤は、上記生グルテン100質量部に対して、油脂5〜8質量部を混練し、乾燥して得られる。その他の成分については、その種類に応じて適宜含有され得る。例えば、上記混練時に合わせて添加してもよく、乾燥後に混合してもよい。
(Food modifier)
The food modifier of the present invention is obtained by kneading and drying 5 to 8 parts by mass of fats and oils with respect to 100 parts by mass of the raw gluten. About another component, it may contain suitably according to the kind. For example, it may be added at the time of the kneading, or may be mixed after drying.

混練工程において、生グルテンと油脂との割合は、上記のとおり、生グルテン100質量部に対して、油脂が5〜8質量部である。5質量部未満の場合、生グルテンと油脂との混合物の伸びが悪く、このような割合で調製された食品改質剤では、食品に十分なしっとり感または弾力性を付与することができない。8質量部を超える場合、生グルテンと油脂との混合物に油浮きが生じ、得られる食品改質剤では食品に十分なしっとり感を付与することができない。生グルテン中に油脂が良好に吸収される(例えば、生グルテンと油脂との混合物を遠心分離した場合においても分離しない)点、および得られる食品改質剤の流動性が良好である点から、生グルテン100質量部に対して、油脂を5〜7質量部とすることが特に好ましい。混練は、例えば、ニーダー、ミキサーなどを用いて行われる。   In the kneading step, the ratio of raw gluten and fat / oil is 5 to 8 parts by mass of fat / oil with respect to 100 parts by weight of raw gluten as described above. When the amount is less than 5 parts by mass, the mixture of raw gluten and fats and oils is poorly stretched, and the food modifier prepared at such a ratio cannot impart sufficient moist feeling or elasticity to the food. When the amount exceeds 8 parts by mass, oil floatation occurs in the mixture of raw gluten and fats and oils, and the resulting food modifier cannot give the food a sufficient moist feeling. From the point that fats and oils are well absorbed in raw gluten (for example, the mixture of raw gluten and fats and oils is not separated even when centrifuged), and the resulting food modifier has good fluidity. It is particularly preferable that the fat is 5 to 7 parts by mass with respect to 100 parts by mass of raw gluten. The kneading is performed using, for example, a kneader or a mixer.

次いで、上記混練物を乾燥する。乾燥は、例えば、混練物中の水分量が10質量%以下になるまで行われる。乾燥方法は、真空乾燥、凍結乾燥などの当業者が通常行う乾燥方法であれば特に制限はない。品質保持の点から、60℃以下の乾燥または凍結乾燥が好ましく用いられる。短時間で乾燥させる点からは真空乾燥が好ましく、例えば50℃〜60℃にて乾燥され得る。生グルテンを取り扱う作業性の点からは凍結乾燥が好ましい。凍結乾燥の場合、凍結させた後、予め粉砕機などで粉砕してから乾燥してもよい。このようにして、本発明の食品改質剤が得られる。   Next, the kneaded product is dried. Drying is performed, for example, until the water content in the kneaded product becomes 10% by mass or less. The drying method is not particularly limited as long as it is a drying method usually performed by those skilled in the art, such as vacuum drying and freeze drying. From the standpoint of quality maintenance, drying at 60 ° C. or lower or freeze drying is preferably used. From the viewpoint of drying in a short time, vacuum drying is preferable, and for example, drying can be performed at 50 ° C to 60 ° C. From the viewpoint of workability for handling raw gluten, lyophilization is preferred. In the case of freeze-drying, the material may be frozen and then pulverized with a pulverizer before drying. In this way, the food modifier of the present invention is obtained.

得られた食品改質剤は、必要に応じて、粉砕される。粉砕は、例えば、ミル、ブレンダーなどの当業者が通常用いる機械または道具により行われ得る。粉砕物の粒径は、用いる食品に応じて適宜設定すればよく特に制限はない。粉砕後、粒径を均一にするために篩い分けなどを行ってもよい。   The obtained food modifier is pulverized as necessary. The crushing can be performed by a machine or tool normally used by those skilled in the art, such as a mill or a blender. The particle size of the pulverized product is not particularly limited as long as it is appropriately set according to the food used. After grinding, sieving or the like may be performed to make the particle size uniform.

本発明の食品改質剤は、加工食品中に含有される油脂と代替した場合にも、その加工食品本来の風味、食感、および外観を損なわず、さらにふんわりとした外観、および良好な食感(しっとり感、もちもち感、および軽い食感)を付与することができる。そのため、本発明の食品改質剤は、特に穀粉を主成分とする加工食品の油脂の代替に有用である。   Even when the food modifier of the present invention is replaced with fats and oils contained in the processed food, it does not impair the original flavor, texture and appearance of the processed food, and has a softer appearance and better food. A feeling (moist feeling, sticky feeling, and light texture) can be imparted. Therefore, the food modifier of the present invention is particularly useful as a substitute for fats and oils in processed foods mainly composed of flour.

本発明の食品改質剤はさらに、加工食品中に含有される油脂と代替した場合に、優れた老化抑制効果を発揮する。例えば、本発明の食品改質剤は、加工食品中に含まれる澱粉の老化(β化)を抑制する。そのため、本発明の食品改質剤は、後述の穀粉を主成分とする加工食品、特に冷凍生地(冷凍パン生地、冷凍パイ生地)、製菓(スポンジケーキ、マフィンなど)、パンなどの食品の老化抑制剤として好適に使用することができる。例えば、本発明の食品改質剤を冷凍生地に用いる場合、解凍してから焼成することによって得られる加工食品の保存後においても、老化が顕著に抑制される。あるいは本発明の食品改質剤を製菓またはパンに用いる場合、食品改質剤を含む生地を予め焼成して冷凍保管しておき、使用時に解凍した後においても、従来の冷凍保管によって生じる生地のボリュームダウン、離水など(老化により生じる)が抑制され、良好な保型性および食感(しっとり感)を有している。   Furthermore, when the food modifier of the present invention is replaced with fats and oils contained in processed foods, it exhibits an excellent antiaging effect. For example, the food modifier of the present invention suppresses aging (β-generation) of starch contained in processed foods. Therefore, the food modifier of the present invention suppresses the aging of processed foods mainly composed of flour, which will be described later, especially frozen dough (frozen bread dough, frozen pie dough), confectionery (sponge cake, muffin, etc.), and bread. It can be suitably used as an agent. For example, when the food modifier of the present invention is used for frozen dough, aging is significantly suppressed even after storage of processed food obtained by thawing and baking. Alternatively, when the food modifier of the present invention is used for confectionery or bread, the dough containing the food modifier is pre-baked and stored frozen, and even after thawing at the time of use, Volume down, water separation, etc. (generated by aging) are suppressed, and it has good shape retention and texture (moist feeling).

(食品改質剤を含む穀粉を主成分とする加工食品)
本発明の加工食品は、穀粉を主成分とし、さらに上記食品改質剤を含む。穀粉としては、麦類(小麦など)、米、とうもろこし、あわ、ひえ、いも類(地下茎を含む)、豆などの植物の澱粉質および蛋白質を主体とする粉末などが挙げられる。中でも、麦粉、特に小麦粉(例えば、強力粉、準強力粉、中力粉、薄力粉など)、米粉などが好ましく用いられる。このような穀粉を主成分とする加工食品としては、例えば、ピザ、中華饅頭、饅頭、どら焼、パンなどの生地、スポンジケーキ、ホットケーキ、クッキー、マフィン、ブッセ、シュー皮などが挙げられる。これらの食品に含有される食品改質剤の量は特に制限されないが、好ましくは得られる加工食品中に、0.1〜20質量%、より好ましくは0.5〜6質量%、さらに好ましくは0.5〜3質量%の割合で含有される。
(Processed foods based on flour containing food modifiers)
The processed food of the present invention is mainly composed of flour and further contains the above-mentioned food modifier. Examples of the flour include wheat (such as wheat), rice, corn, awa, koe, potato (including rhizomes), beans and other plant starches and powders mainly composed of proteins. Among these, wheat flour, particularly wheat flour (for example, strong flour, semi-strong flour, medium flour, thin flour, etc.), rice flour and the like are preferably used. Examples of processed foods mainly composed of such flour include doughs such as pizza, Chinese buns, buns, dorayaki, bread, etc., sponge cakes, hot cakes, cookies, muffins, busses, shoe skins, and the like. The amount of the food modifier contained in these foods is not particularly limited, but is preferably 0.1 to 20% by mass, more preferably 0.5 to 6% by mass, and still more preferably in the obtained processed food. It is contained at a ratio of 0.5 to 3% by mass.

本発明の加工食品は、上記食品改質剤を含むため、従来に比べて、同等以上の外観を有し、かつしっとり感(保湿性)、もちもち感、軽い食感などの良好な食感を有している。特に、本発明の加工食品中に、油脂の代替として食品改質剤が含まれている場合、この加工食品は、油脂を含まないにもかかわらず、しっかり保型され、かつ従来の油脂を含む加工食品に比べてふんわりとした外観を有しており、そしてしっとり感に優れている。   Since the processed food of the present invention contains the above-described food modifier, it has an appearance equal to or better than that of the conventional food, and has a good texture such as a moist feeling (moisturizing property), a sticky feeling, and a light texture. Have. In particular, when the processed food of the present invention contains a food modifier as a substitute for fats and oils, the processed foods are firmly shaped and contain conventional fats and oils even though they do not contain fats and oils. Compared to processed foods, it has a softer appearance and is moist.

(実施例1:食品改質剤の調製)
小麦粉100質量部に、水70質量部を加えて混練して生地(ドウ)を得、このドウを水洗して澱粉を除去し、生グルテン(小麦グルテン)を得た。この生グルテン100gと、サフラワー油7gと、ピロ亜硫酸ナトリウム0.03gとをミキサーで混合した後、混合物を急速凍結して凍結乾燥を行った。得られた乾燥物を粉砕して粉末40gを得た(食品改質剤とする)。
(Example 1: Preparation of food modifier)
70 parts by weight of water was added to 100 parts by weight of wheat flour and kneaded to obtain a dough (dough). The dough was washed with water to remove starch, and raw gluten (wheat gluten) was obtained. 100 g of this raw gluten, 7 g of safflower oil, and 0.03 g of sodium pyrosulfite were mixed with a mixer, and then the mixture was rapidly frozen and freeze-dried. The obtained dried product was pulverized to obtain 40 g of powder (referred to as a food modifier).

(実施例2:ピザ台の調製および評価)
実施例1で得られた食品改質剤と、表1に記載の各成分とを表1に記載の割合で混合し、ピザの生地を得た。この生地140gを薄く伸ばして半径約20cmの円形(厚さ0.2cm)に成形した後、オーブンを用いて200℃にて8分間加熱してピザ台を得た(実施例2とする)。このピザ台の質量は115gであり、厚みは1.5cmであった。
(Example 2: Preparation and evaluation of pizza table)
The food modifier obtained in Example 1 and each component listed in Table 1 were mixed in the proportions described in Table 1 to obtain a pizza dough. 140 g of this dough was thinly stretched and formed into a circle (thickness 0.2 cm) with a radius of about 20 cm, and then heated at 200 ° C. for 8 minutes using an oven to obtain a pizza stand (referred to as Example 2). The mass of this pizza stand was 115 g, and the thickness was 1.5 cm.

食品改質剤を用いなかったこと以外は、上記実施例2と同様にしてピザ台を得た(比較試験例2−1とする)。このピザ台の質量は115gであり、厚みは0.7cmであった。   A pizza stand was obtained in the same manner as in Example 2 except that no food modifier was used (referred to as Comparative Test Example 2-1). The mass of this pizza stand was 115 g, and the thickness was 0.7 cm.

水100gと、サフラワー油7gとを乳化機にて混合し乳化油脂を調製した。食品改質剤の代わりにこの乳化油脂2gを用いたこと以外は、上記実施例2と同様にしてピザ台を得た(比較試験例2−2とする)。   100 g of water and 7 g of safflower oil were mixed with an emulsifier to prepare an emulsified oil. A pizza stand was obtained in the same manner as in Example 2 except that 2 g of this emulsified oil and fat was used instead of the food modifier (referred to as Comparative Test Example 2-2).

実施例1の食品改質剤の調製において、サフラワー油の代わりに、水を用いて、グルテン粉末を得た。食品改質剤の代わりに、このグルテン粉末および乳化油脂を用いたこと以外は、上記実施例2と同様にしてピザ台を得た(比較試験例2−3とする)。   In the preparation of the food modifier of Example 1, gluten powder was obtained using water instead of safflower oil. A pizza stand was obtained in the same manner as in Example 2 except that this gluten powder and emulsified oil and fat were used in place of the food modifier (referred to as Comparative Test Example 2-3).

実施例1で得られた食品改質剤と、表8に記載の各成分とを、当業者が通常用いるスポンジケーキの調理方法にしたがって混合し、オーブンで加熱してスポンジケーキを得た(実施例9−1とする)。スポンジケーキの質量は320gであった。なお、表8の配合において、グルテンを添加するとスポンジケーキの生地が硬くなる傾向があるため、食品改質剤1質量部に対して水を2質量部多く配合している。すなわち実施例9−1において、食品改質剤2gに対して水4gを配合している。
(Example 9: Evaluation of moisture retention)
The food modifier obtained in Example 1 and each component shown in Table 8 were mixed according to a sponge cake cooking method commonly used by those skilled in the art, and heated in an oven to obtain a sponge cake (Implementation) Example 9-1). The mass of the sponge cake was 320 g. In addition, in composition of Table 8, since the dough of sponge cake tends to become hard when gluten is added, 2 mass parts of water is blended more than 1 mass part of the food modifier. That is, in Example 9-1, 4 g of water is blended with 2 g of the food modifier.

NSM(液体マーガリン、株式会社カネカ)の代わりに水を用いること以外は、上記実施例4−1と同様にしてスポンジケーキを得た(実施例9−2とする)。スポンジケーキの質量は320gであった。   A sponge cake was obtained in the same manner as in Example 4-1 except that water was used instead of NSM (liquid margarine, Kaneka Corporation) (referred to as Example 9-2). The mass of the sponge cake was 320 g.

食品改質剤を用いないこと以外は、上記実施例9−1と同様にしてスポンジケーキを得た(比較試験例9−1とする)。   A sponge cake was obtained in the same manner as in Example 9-1 except that no food modifier was used (referred to as Comparative Test Example 9-1).

食品改質剤を用いないこと、およびNSMの代わりに水を用いること以外は、上記実施例9−1と同様にしてスポンジケーキを得た(比較試験例9−2とする)。   A sponge cake was obtained in the same manner as in Example 9-1 except that no food modifier was used and water was used instead of NSM (referred to as Comparative Test Example 9-2).

実施例9−1および9−2のスポンジケーキ、ならびに比較試験例9−1および9−2のスポンジケーキの保湿性について、20名のパネラーに試食させ、「しっとりしている」および「ぱさぱさする」のいずれかで回答してもらった。「しっとりしている」と回答した人数が多い程、保湿性に優れているとして官能評価を行った。さらに、これらのスポンジケーキの水分活性をEZ−100(フロイント産業株式会社製)を用いて測定した。水分活性が高いほど、しっとり感(保湿性)に優れていると判断した。結果を表8に示す。なお、表8の評価結果の欄において、上段には官能評価の結果(「しっとりしている」と回答した人数)を示し、下段には水分活性の測定値を示す。   About the moisture retention of the sponge cakes of Examples 9-1 and 9-2 and the sponge cakes of Comparative Test Examples 9-1 and 9-2, 20 panelists tasted them, “moist” and “paspy” "I had you answer with either. The more people who answered “moist”, the better the moisture retention, the sensory evaluation was performed. Furthermore, the water activity of these sponge cakes was measured using EZ-100 (Freund Sangyo Co., Ltd.). It was judged that the higher the water activity, the better the moist feeling (moisturizing property). The results are shown in Table 8. In the evaluation result column of Table 8, the upper part shows the result of sensory evaluation (number of people who answered “moist”), and the lower part shows the measured value of water activity.

さらに、これらのスポンジケーキをそれぞれ常温にて保存し、保存開始から5日目、8日目、15日目、21日目、および30日目に、上記と同様にして、保湿性の官能評価および水分活性の測定を行った。結果を表8に併せて示す   Further, each of these sponge cakes was stored at room temperature, and on the 5th, 8th, 15th, 21st and 30th days from the start of storage, the moisturizing sensory evaluation was performed in the same manner as described above. And water activity measurements. The results are also shown in Table 8.

Figure 2008136481
Figure 2008136481

表8の結果から、実施例9−1および9−2の食品改質剤を含むスポンジケーキは、比較試験例9−1および9−2の食品改質剤を含まないスポンジケーキに比べて、保存開始0日目(調理当日)の官能評価において「しっとりしている」と回答した人数が多く、保湿性が向上していることがわかる。さらに、官能評価の結果から、これらの実施例9−1および9−2のスポンジケーキは、30日間保存した場合においても良好な保湿性を維持していることがわかる。この良好な保湿性は、保存期間(30日間)中において、スポンジケーキの水分活性が0.93〜0.96と高い値で安定していることからも確認された。このように、本発明の食品改質剤を用いて得られる加工食品は、優れた保湿性を有し、かつこの保湿性が長期間維持される。他方、比較試験例9−1および9−2の食品改質剤を含まないスポンジケーキは、保存開始15日目の官能評価において、しっとりしているとの保湿性を示す回答は全く得られなくなった。水分活性についても30日間保存した場合、0.89以下と低い値であった。   From the results of Table 8, the sponge cake containing the food modifiers of Examples 9-1 and 9-2 was compared with the sponge cake containing no food modifier of Comparative Test Examples 9-1 and 9-2. It can be seen that there are many people who answered “moist” in the sensory evaluation on the first day of storage (cooking day), and the moisture retention was improved. Furthermore, from the result of sensory evaluation, it can be seen that the sponge cakes of Examples 9-1 and 9-2 maintain good moisture retention even when stored for 30 days. This good moisturizing property was also confirmed from the fact that the water activity of the sponge cake was stable at a high value of 0.93 to 0.96 during the storage period (30 days). Thus, the processed food obtained using the food modifier of the present invention has excellent moisturizing properties, and the moisturizing properties are maintained for a long time. On the other hand, the sponge cake that does not contain the food modifier of Comparative Test Examples 9-1 and 9-2 cannot obtain any answer indicating moisturizing properties as moist in the sensory evaluation on the 15th day from the start of storage. It was. The water activity was a low value of 0.89 or less when stored for 30 days.

(実施例10:硬さ、弾力性の評価)
実施例1の生グルテン100質量部に、サフラワー油5質量部を添加した後、混練した。次いで、この混練物を遠心チューブに入れて脱気し、(真空)凍結乾燥して食品改質剤Aを得た。この食品改質剤Aを蒸し器に入れ、85℃にて50分間蒸してゲルを得た(実施例10−1とする)。
(Example 10: Evaluation of hardness and elasticity)
After adding 5 parts by mass of safflower oil to 100 parts by mass of raw gluten of Example 1, the mixture was kneaded. Next, the kneaded product was put in a centrifuge tube, degassed, and (vacuum) lyophilized to obtain a food modifier A. This food modifier A was put in a steamer and steamed at 85 ° C. for 50 minutes to obtain a gel (referred to as Example 10-1).

還元処理したグルテン100質量部に、サフラワー油7質量部を添加したこと以外は、上記実施例10−1と同様にして食品改質剤Bを得、ゲルを調製した(実施例10−2とする)。   Except that 7 parts by mass of safflower oil was added to 100 parts by mass of the reduced gluten, food modifier B was obtained in the same manner as in Example 10-1, and a gel was prepared (Example 10-2). And).

これとは別に、比較のために3種類のゲルを以下のようにして調製した。上記食品改質剤の代わりに、実施例1の生グルテンのみを用いたこと以外は、上記実施例10−1と同様にしてゲルを得た(比較試験例10−1とする)。還元処理したグルテン100質量部に、サフラワー油3質量部を添加したこと以外は、上記実施例10−1と同様にして食品改質剤Cを得、ゲルを調製した(比較試験例10−2とする)。そして還元処理したグルテン100質量部に、サフラワー油10質量部を添加したこと以外は、上記実施例10−1と同様にして食品改質剤Dを得、ゲルを調製した(比較試験例10−3とする)。   Separately, three types of gels were prepared for comparison as follows. A gel was obtained in the same manner as in Example 10-1 except that only the raw gluten of Example 1 was used instead of the food modifier (referred to as Comparative Test Example 10-1). Except that 3 parts by mass of safflower oil was added to 100 parts by mass of the reduced gluten, a food modifier C was obtained in the same manner as in Example 10-1, and a gel was prepared (Comparative Test Example 10- 2). And the food modifier D was obtained similarly to the said Example 10-1 except having added 10 mass parts of safflower oil to 100 mass parts of reduced gluten, and the gel was prepared (Comparative Test Example 10). -3).

得られた5種類のゲル(実施例10−1および10−2、ならびに比較試験例10−1〜10−3)について以下の試験を行い、硬さおよび弾力性を評価した。   The following tests were performed on the obtained five types of gels (Examples 10-1 and 10-2 and Comparative Test Examples 10-1 to 10-3), and the hardness and elasticity were evaluated.

まず、ゲルを直径2.5cmおよび高さ1.5cmの円柱状にカットし、テキソグラフ(株式会社日本食品開発研究所)にセットした。円柱状のゲルをプランジャーで圧縮し、ゲルの高さが0.6cmになったときの荷重を測定した。   First, the gel was cut into a cylindrical shape having a diameter of 2.5 cm and a height of 1.5 cm, and set in a texograph (Japan Food Research Laboratories). A cylindrical gel was compressed with a plunger, and the load when the height of the gel reached 0.6 cm was measured.

その後、プランジャーを戻し、ゲルの高さ(圧縮終了後の高さ)を測定した。試験前のゲルの高さ(1.5cm)に対する圧縮終了後の高さの割合を回復率として算出した。この試験を10回繰り返して荷重および回復率の平均値をそれぞれ求め、荷重の平均値から硬さを、回復率の平均値から弾力性を評価した。結果を図6および図7に示す。   Thereafter, the plunger was returned, and the height of the gel (height after completion of compression) was measured. The ratio of the height after completion of compression to the height of the gel (1.5 cm) before the test was calculated as the recovery rate. This test was repeated 10 times to determine the average value of the load and the recovery rate, and the hardness was evaluated from the average value of the load, and the elasticity was evaluated from the average value of the recovery rate. The results are shown in FIG. 6 and FIG.

図6および図7から明らかなように、実施例10−1および10−2の食品改質剤AおよびBを用いた場合は、適度な硬さ(20000Pa以上)を有し、かつ優れた弾力性(回復率はそれぞれ73%および76%)を有していた。他方、比較試験例10−1の生グルテンのみ、あるいは比較試験例10−2の食品改質剤Cを用いる場合は、十分な硬さは得られるものの、弾力性の点で劣った(回復率はそれぞれ65%および71%)。比較試験例10−3の食品改質剤Dを用いる場合は、弾力性はあるものの(回復率77%)、十分な硬さが得られなかった。   As is apparent from FIGS. 6 and 7, when the food modifiers A and B of Examples 10-1 and 10-2 were used, they had an appropriate hardness (20000 Pa or more) and excellent elasticity. (Recovery rates were 73% and 76%, respectively). On the other hand, when only the raw gluten of Comparative Test Example 10-1 or the food modifier C of Comparative Test Example 10-2 is used, although sufficient hardness is obtained, it is inferior in elasticity (recovery rate) Are 65% and 71% respectively). When the food modifier D of Comparative Test Example 10-3 was used, although it was elastic (recovery rate 77%), sufficient hardness was not obtained.

さらに、実施例10−2の食品改質剤B、比較試験例10−1の生グルテンのみ、および比較試験例10−3の食品改質剤Dをそれぞれ用いて、各種食品(スポンジケーキ、中華饅頭、コッペパン、および食パン)を常法により調製し、外観および風味について評価した。その結果、実施例10−2の食品改質剤Bを用いる場合は、いずれの食品も適度なボリューム感を有し、かつしっとり感、ふんわり感が良好であった。他方、比較試験例10−1の生グルテンのみを用いる場合、得られる食品はいずれも硬く、口溶けが悪く、しっとり感がなかった。そして比較試験例10−3の食品改質剤Dを用いる場合は、いずれの食品も、風味に油っぽさを感じ、生地にべたつきがあった。   Furthermore, various foods (sponge cakes, Chinese foods) were obtained using only the food modifier B of Example 10-2, only the raw gluten of Comparative Test Example 10-1, and the food modifier D of Comparative Test Example 10-3. The buns, chopped bread, and bread) were prepared by conventional methods and evaluated for appearance and flavor. As a result, when the food modifier B of Example 10-2 was used, all the foods had an appropriate volume feeling, and were moist and soft. On the other hand, when only the raw gluten of Comparative Test Example 10-1 was used, the foods obtained were all hard, poorly melted in the mouth, and did not feel moist. And when using the foodstuff modifier D of the comparative test example 10-3, all the foods felt oily to flavor and the dough was sticky.

(実施例11:老化抑制効果の評価1(スポンジケーキ))
卓上ミキサー5DM型(株式会社品川工業所)を用いて、実施例10−2で調製された食品改質剤Bと、表9に記載の各成分とを、表9の割合で、オールインミックス法により混合して(高速攪拌2分)、スポンジケーキ生地1および2を得た(実施例11−1および11−2)。なお、対照例として、食品改質剤Bの代わりに、市販の液体油脂のみを用いてスポンジケーキ生地3を調製した。これらの生地1〜3の比重は、いずれも0.46〜0.48であった。
(Example 11: Evaluation 1 of antiaging effect (sponge cake))
Using a tabletop mixer 5DM type (Shinagawa Kogyo Co., Ltd.), all-in-mix of the food modifier B prepared in Example 10-2 and the components shown in Table 9 in the proportions shown in Table 9 Mixing by the method (high speed stirring for 2 minutes) gave sponge cake doughs 1 and 2 (Examples 11-1 and 11-2). As a control example, sponge cake dough 3 was prepared using only commercially available liquid oil and fat instead of food modifier B. The specific gravities of these fabrics 1 to 3 were all 0.46 to 0.48.

各生地(生地1〜3)120gを直径12cmのケーキ型に流し込み、170℃にて30分間焼成してスポンジケーキ1〜3(デコ台)を得た。得られたスポンジケーキ1〜3について、β−アミラーゼ・プルラナーゼ法(BAP法)を用いて糊化度(α化度:製造直後の糊化度)を測定した。BAP法は、試料中の澱粉をアルカリ処理により完全糊化したα化澱粉の量を100%として、試料を酵素分解したもののα化澱粉の量の割合を測定する方法である。糊化度(%)は、その値が低い程、澱粉のβ化が進み、老化していることを示す。なお、測定にはスポンジケーキの中心部分を用いた。   120 g of each dough (doughs 1 to 3) was poured into a cake mold having a diameter of 12 cm and fired at 170 ° C. for 30 minutes to obtain sponge cakes 1 to 3 (deco table). About the obtained sponge cakes 1-3, the gelatinization degree (alpha conversion degree: the gelatinization degree immediately after manufacture) was measured using the (beta) -amylase pullulanase method (BAP method). The BAP method is a method of measuring the ratio of the amount of pregelatinized starch in a sample obtained by enzymatic degradation, with the amount of pregelatinized starch obtained by completely gelatinizing the starch in the sample as 100%. The degree of gelatinization (%) indicates that the lower the value is, the more β starch is aged and it is aging. In addition, the center part of the sponge cake was used for the measurement.

さらに、各スポンジケーキ1〜3を常温にて保存し、保存してから20日目および30日目に、各スポンジケーキの糊化度を測定した。結果を図8に示す。   Furthermore, each sponge cake 1-3 was preserve | saved at normal temperature, and the gelatinization degree of each sponge cake was measured on the 20th day and 30th day after it preserve | saved. The results are shown in FIG.

図8から明らかなように、実施例11−1の食品改質剤を含むスポンジケーキ1(液体油脂非含有)の糊化度は、製造直後で78%、保存30日後で41%であり、30日間の保存により38%低下した。実施例11−2の食品改質剤を含むスポンジケーキ2(液体油脂含有)の糊化度は、製造直後で74%、保存30日後で38%であり、30日間の保存により36%低下した。他方、対照例の食品改質剤を含まないスポンジケーキ3の糊化度は、製造直後で72%、保存30日後で22%であり、30日間の保存により50%低下した。このように、実施例11−1および11−2の食品改質剤を含むスポンジケーキ1および2は、対照例の食品改質剤を含まないスポンジケーキ3に比べて、澱粉の老化が抑制されていることがわかる。さらに実施例11−1および2から明らかなように、食品改質剤を含む場合は、液体油脂の有無に関わらず、澱粉の老化が抑制されていた。このような澱粉の老化抑制効果は、得られる加工食品の食感(しっとり感)の維持に反映されることが期待される。   As is apparent from FIG. 8, the degree of gelatinization of the sponge cake 1 (containing no liquid fat) containing the food modifier of Example 11-1 was 78% immediately after production and 41% after 30 days of storage. It decreased by 38% after 30 days of storage. The degree of gelatinization of sponge cake 2 (containing liquid fat) containing the food modifier of Example 11-2 was 74% immediately after production, 38% after 30 days of storage, and decreased by 36% after 30 days of storage. . On the other hand, the gelatinization degree of the sponge cake 3 containing no food modifier of the control example was 72% immediately after production, 22% after 30 days of storage, and decreased by 50% by storage for 30 days. Thus, in the sponge cakes 1 and 2 containing the food modifiers of Examples 11-1 and 11-2, aging of the starch was suppressed as compared to the sponge cake 3 not containing the food modifier of the control example. You can see that Furthermore, as is clear from Examples 11-1 and 2, when a food modifier was included, aging of starch was suppressed regardless of the presence or absence of liquid fat. Such an anti-aging effect of starch is expected to be reflected in the maintenance of the texture (moist feeling) of the obtained processed food.

(実施例12:老化抑制効果の評価2(コッペパン))
卓上ミキサー5DM型(株式会社品川工業所)に、実施例10−2で調製された食品改質剤Bと、表10に記載のマーガリン以外の各成分とを表10の割合で投入し、低速で4分間および高速で4分間攪拌して混合した。次いで、マーガリンを表10の割合で投入し、さらに低速で4分間および高速で4分間攪拌して混合し、生地を得た。この生地を、湿度80%の条件下で28℃にて20分間1次発酵を行った。次いで、この生地を50gに分割し、ベンチタイムを20分間確保した。さらに、湿度80%の条件下で38℃にて50分間2次発酵(ホイロ)を行い、200℃にて14分間焼成した。冷却後、コッペパン1を得た。なお、対照例として、食品改質剤を使用しないこと以外は、上記と同様にしてコッペパン2を得た。
(Example 12: Evaluation 2 of aging inhibitory effect (copper bread))
A table mixer 5DM type (Shinagawa Kogyo Co., Ltd.) was charged with the food modifier B prepared in Example 10-2 and each component other than margarine listed in Table 10 in the proportions shown in Table 10, and the low speed And stirred for 4 minutes at high speed and 4 minutes at high speed. Next, margarine was added at the ratio shown in Table 10, and the mixture was further stirred for 4 minutes at low speed and for 4 minutes at high speed to obtain a dough. This dough was subjected to primary fermentation at 28 ° C. for 20 minutes under the condition of 80% humidity. Next, this dough was divided into 50 g, and a bench time was secured for 20 minutes. Further, secondary fermentation (probing) was performed at 38 ° C. for 50 minutes under the condition of 80% humidity, followed by baking at 200 ° C. for 14 minutes. After cooling, copper pan 1 was obtained. In addition, as a control example, a cupe bread 2 was obtained in the same manner as above except that no food modifier was used.

Figure 2008136481
Figure 2008136481

得られたコッペパン1および2について、β−アミラーゼ・プルラナーゼ法(BAP法)を用いて糊化度(製造直後の糊化度)を測定した。なお、測定にはコッペパンの中心部分を用いた。その後、各コッペパン1および2をポリエチレン袋に入れ、常温にて保存し、保存してから2日目および3日目に、コッペパン1および2の糊化度をさらに測定した。結果を図9に示す。   About the obtained coppe bread 1 and 2, the gelatinization degree (gelatinization degree immediately after manufacture) was measured using the (beta) -amylase pullulanase method (BAP method). In addition, the center part of the copper pan was used for the measurement. Thereafter, each of the coppe breads 1 and 2 was put in a polyethylene bag, stored at room temperature, and the gelatinization degree of the coppe breads 1 and 2 was further measured on the second and third days after storage. The results are shown in FIG.

図9から明らかなように、食品改質剤を含むコッペパン1(実施例12)の糊化度は、製造直後で80%、保存3日後で67%であり、3日間の保存により13%低下した。他方、食品改質剤を含まないコッペパン2(対照例)の糊化度は、製造直後で79%、保存3日後で56%であり、3日間の保存により23%低下した。このように、食品改質剤を含むコッペパン1は、食品改質剤を含まないコッペパン2に比べて、澱粉の老化が抑制されていることがわかる。このような澱粉の老化抑制効果は、得られる加工食品の食感(しっとり感)の維持に反映されることが期待される。   As is clear from FIG. 9, the degree of gelatinization of Coppé bread 1 (Example 12) containing a food modifier is 80% immediately after production, 67% after 3 days of storage, and is reduced by 13% after storage for 3 days. did. On the other hand, the gelatinization degree of Coppépan 2 (control example) containing no food modifier was 79% immediately after production, 56% after 3 days of storage, and decreased by 23% after storage for 3 days. Thus, it can be seen that the coppe bread 1 containing the food modifier has suppressed starch aging compared to the coppe bread 2 not containing the food modifier. Such an anti-aging effect of starch is expected to be reflected in the maintenance of the texture (moist feeling) of the obtained processed food.

本発明によれば、加工食品、特に穀粉を主成分とする加工食品に対して、しっとり感および軽い食感を付与することができる食品改質剤が提供される。特に、穀粉を主成分とし、かつ油脂を含む加工食品において、該油脂の一部または全部を、上記食品改質剤と代替した場合、得られる加工食品の風味、食感、および外観を損なうことなく、さらにふんわりとした外観、および良好な食感(しっとり感、もちもち感、および軽い食感)を付与することができる。さらに、得られる加工食品の老化(特に澱粉の老化)を抑制することができる。したがって、本発明の食品改質剤は、特に穀粉を主成分とする加工食品の油脂の代替に有用である。   ADVANTAGE OF THE INVENTION According to this invention, the food modifier which can provide a moist feeling and a light texture with respect to processed food, especially processed food which has flour as a main component is provided. In particular, in processed foods mainly composed of flour and containing fats and oils, when part or all of the fats and oils are replaced with the above-mentioned food modifiers, the flavor, texture and appearance of the obtained processed foods are impaired. In addition, a softer appearance and a good texture (moist feeling, sticky feeling, and light texture) can be imparted. Furthermore, aging (especially aging of starch) of the processed food obtained can be suppressed. Therefore, the food modifier of the present invention is particularly useful as a substitute for fats and oils in processed foods mainly composed of flour.
