Description

本発明は、焙煎大麦の溶剤抽出物からなる飲食品の風味改善剤に関する。   The present invention relates to a flavor improving agent for foods and drinks comprising a solvent extract of roasted barley.

食品や飲料にはその含有成分に由来する独特の風味があり、飲食品によっては不快味を伴うものがある。例えば、乳製品や乳系飲料の生臭さ臭、穀物利用食品の粉っぽさ、魚介類の生臭さ臭、豆乳の青臭さ臭又は豆臭を不快味と感じる人々も少なくない。飲食品の不快味をマスキングあるいは改善するために、飲食物を物理的・化学的に処理したり、香料、酵素、植物の抽出物、合成化学品等を飲食品に添加したりしてきた。このようなマスキング剤又は風味改良剤に関する提案も、従来から数多くなされている。   Foods and beverages have a unique flavor derived from the components contained therein, and some foods and drinks have an unpleasant taste. For example, there are many people who feel unpleasant taste of raw odor of dairy products and milk-based beverages, powdery cereal-based foods, raw odor of seafood, blue odor of soybean milk or bean odor. In order to mask or improve the unpleasant taste of foods and drinks, foods and drinks have been treated physically and chemically, and fragrances, enzymes, plant extracts, synthetic chemicals and the like have been added to foods and drinks. Many proposals regarding such masking agents or flavor improving agents have been made.

例えば、特許文献1には、乳清ミネラルの添加によるカゼインナトリウム類のカゼイン臭の低減方法が開示されている。特許文献2には、高い甘味を示す甘味料のスクラロースを含有する乳感の向上したヨーグルト等の乳含有製品が提案されている。特許文献3には、上記スクラロースを有効成分として、米粉、小麦粉、そば粉、トウモロコシ粉等の穀物粉の粉臭さをマスキングするマスキング剤が提案されている。特許文献4には、マッシュポテト、食パン、うどん等の澱粉加工食品、又はシーチキン、赤貝味付等の魚肉加工食品に、香味野菜、トマト、香辛料及びきのこ類から選ばれる1種以上を原材料とする野菜エキスを添加して、澱粉又は魚肉特有の臭いを低減又は除去し得る呈味改善剤が開示されている。特許文献5には、セスキテルペンを含有する柑橘類由来の抽出物をマスキング剤とする豆乳臭のマスキング用組成物が開示されている。
また、焙煎大麦の水抽出物を風味改善剤とする従来技術としては特許文献6がある。この風味改善剤は、酸味料が添加された加熱処理米飯の酸味及び酸刺激臭を改善するためのものである。

For example, Patent Document 1 discloses a method for reducing casein odor of sodium caseinates by adding whey minerals. Patent Document 2 proposes a milk-containing product such as yogurt with improved milk texture containing sucralose, a sweetener exhibiting high sweetness. Patent Document 3 proposes a masking agent that masks the odor of cereal flour such as rice flour, wheat flour, buckwheat flour, and corn flour, using sucralose as an active ingredient. Patent Document 4 discloses a vegetable processed from starch processed foods such as mashed potatoes, bread and udon, or fish processed foods such as seasoned chicken and red shellfish, and one or more ingredients selected from flavored vegetables, tomatoes, spices and mushrooms. A taste improver is disclosed that can add or extract to reduce or eliminate the odor characteristic of starch or fish meat. Patent Document 5 discloses a composition for masking soymilk odor using a citrus-derived extract containing a sesquiterpene as a masking agent.
Moreover, there exists patent document 6 as a prior art which uses the water extract of roasted barley as a flavor improving agent. This flavor improving agent is for improving the acidity and acid-stimulated odor of heat-treated cooked rice to which a sour agent is added.

以上の従来技術において、特許文献1は、カゼインナトリウム類に対して乳清ミネラルを大量に添加しなければカゼイン臭の低減効果が得られず、経済的とはいえない。特許文献2,3は、6ppm以上の添加で甘みを感じると記載されているように、スクラロース自体が高い甘味を呈する甘味料であり、可及的に甘味を抑制したい食品への適用が困難であるため、乳感向上剤又は粉臭のマスキング剤としての使用が制限されるという問題がある。特許文献4は、野菜エキス(呈味改善剤)の原材料が多岐にわっており、澱粉又は魚肉特有の臭いを低減又は除去し得る野菜エキスの添加量も比較的多いきらいがある。特許文献5は、豆乳臭のマスキング効果はあるものの、豆乳のコク味が減少するという欠点がある。また、特許文献6には、酸味料添加の加熱処理米飯以外の飲食品に対する焙煎大麦抽出物の風味改善効果については開示がない。
そこで、本発明の目的は、比較的少量で特定の飲食品の不快味をマスキングするかあるいは広範な飲食品の風味を向上させ、しかも、使用が制限されることのない飲食品の風味改善剤を提供することにある。
In the above prior art, Patent Document 1 is not economical unless the whey mineral is added in a large amount to casein sodium, and the effect of reducing casein odor cannot be obtained. Patent Documents 2 and 3 describe that sweetness is felt when added at 6 ppm or more, and sucralose itself is a sweetener that exhibits high sweetness, and is difficult to apply to foods that want to suppress sweetness as much as possible. Therefore, there is a problem that use as a milky feeling improving agent or a powdery odor masking agent is limited. Patent Document 4 has a wide variety of raw materials for vegetable extracts (taste improving agents), and the amount of vegetable extracts that can reduce or eliminate the odor peculiar to starch or fish meat tends to be relatively large. Although patent document 5 has the masking effect of a soymilk smell, there exists a fault that the rich taste of soymilk reduces. Patent Document 6 does not disclose the flavor improving effect of the roasted barley extract on foods and drinks other than the heat-treated cooked rice with acidulant added.
Therefore, an object of the present invention is to mask the unpleasant taste of a specific food or drink with a relatively small amount, or to improve the flavor of a wide range of food or drink, and the use of the flavor improving agent for food or drink is not restricted. Is to provide.

At the same time, the taste can be complementarily improved to further enhance the effect of addition to food and drink.

以下、本発明について詳細に説明する。
本発明の飲食品の風味改善剤は、焙煎大麦の溶剤抽出物を有効成分とする。大麦の品種としては、二条大麦、六条大麦、ハダカ麦等がある。大麦の焙煎処理は、大麦を天然砂と共に加熱する方法、大麦を熱風により加熱する方法、大麦を直接加熱する方法等、焙煎香気を発生させるために麦茶の製造で実施されている方法が適用できる。その際の焙煎の程度の目安となるL値(色の濃淡を示す指数)は、10〜60の範囲にあり、15〜45の範囲にあることが好ましい。
Hereinafter, the present invention will be described in detail.
The flavor improving agent for food and drink according to the present invention contains a solvent extract of roasted barley as an active ingredient. Barley varieties include Nijo barley, Rokujo barley, and Hadaka barley. The barley roasting process is a method carried out in the production of barley tea to generate roasting aroma, such as a method of heating barley with natural sand, a method of heating barley with hot air, or a method of directly heating barley. Applicable. In this case, the L value (index indicating color shading) that is a measure of the degree of roasting is in the range of 10 to 60, and preferably in the range of 15 to 45.

焙煎大麦の溶剤抽出には、人体に安全なエタノール水溶液が用いられる。かかる溶剤のエタノール濃度は0〜95重量%の範囲にある。焙煎大麦の有効成分の抽出処理は、通常40〜100℃の加温下で行われるが、蒸発による溶剤の損失を避けるために、40〜140℃の温度の加圧容器(オートクレーブ)中で実施することもできる。
本発明の飲食品の風味改善剤は水に可溶であるが、水を抽出溶剤とした場合、風味改善効果のない糖類やタンパク質等の非有効成分も同時に抽出されるので、風味改善剤として単位固形分当たりの力価の低いものが得られる。非有効成分はエタノールに不溶であるので、水抽出後にエタノールを添加して非有効成分を沈殿させ、除去することができる。これに代わる抽出法として、エタノール水溶液を用い、焙煎大麦を直接抽出して有効成分を得ることできる。
For solvent extraction of roasted barley, an ethanol aqueous solution that is safe for the human body is used. The ethanol concentration of such a solvent is in the range of 0 to 95% by weight. The extraction process of the active ingredients of roasted barley is usually carried out under heating at 40-100 ° C., but in a pressurized container (autoclave) at a temperature of 40-140 ° C. in order to avoid solvent loss due to evaporation. It can also be implemented.
The flavor improving agent for food and drink of the present invention is soluble in water, but when water is used as an extraction solvent, non-active ingredients such as sugars and proteins that do not have a flavor improving effect are also extracted at the same time. A product having a low titer per unit solid content is obtained. Since inactive ingredients are insoluble in ethanol, ethanol can be added after water extraction to precipitate and remove the ineffective ingredients. As extraction method alternative, using an aqueous ethanol solution, it is possible to obtain an active ingredient by extracting roasted barley directly.

ここで、図1は、焙煎大麦を各種エタノール濃度の水溶液で室温下に一夜静置して抽出したときの水での抽出量に対する可溶成分の抽出率を示す。図2は、同様の条件下で抽出される焙煎大麦中の可溶成分の量(重量%)を示す。図1,2から、エタノール濃度が高くなるに従って、抽出率及び可溶成分量は低下することが分かる。図3は、焙煎大麦の熱水抽出物にエタノールを加えて所定のエタノール濃度としたときに生じる沈殿量を熱水抽出物に対する比率(沈殿率)で表したものである。上記非有効成分の沈殿率は、エタノール濃度が30重量%から約60重量%にかけて急激に上昇し、60重量%からはなだらかに高くなるが、75〜95重量%ではほぼ一定である。
沈殿率を示す図3から、非有効成分の抽出を抑制して風味改善剤の力価を高めるためには、濃度30〜95重量%、特に60〜75重量%のエタノール水溶液を抽出溶剤とすることが好ましい。
Here, FIG. 1 shows the extraction rate of soluble components with respect to the extraction amount in water when roasted barley is extracted with aqueous solutions of various ethanol concentrations by standing overnight at room temperature. FIG. 2 shows the amount (% by weight) of soluble components in roasted barley extracted under similar conditions. 1 and 2 that the extraction rate and the amount of soluble components decrease as the ethanol concentration increases. FIG. 3 shows the amount of precipitation that occurs when ethanol is added to a hot water extract of roasted barley to obtain a predetermined ethanol concentration as a ratio (precipitation rate) to the hot water extract. The precipitation rate of the above-mentioned inactive ingredients increases rapidly from 30 wt% to about 60 wt% and gradually increases from 60 wt%, but is almost constant at 75 to 95 wt%.
From FIG. 3 showing the precipitation rate, in order to suppress the extraction of inactive ingredients and increase the potency of the flavor improving agent, an aqueous ethanol solution having a concentration of 30 to 95% by weight, particularly 60 to 75% by weight, is used as the extraction solvent. It is preferable.

低濃度エタノール水溶液に溶解した抽出物は、腐敗を避けるために、噴霧乾燥、凍結乾燥等により粉末化することが好ましい。また、飲食品の風味を損なわない賦形剤を用いて顆粒状とすることもできる。
高濃度エタノール水溶液に溶解した抽出物は、エキスとしてそのまま製品としてもよいが、更に力価を高めるために、濃縮した後エタノール又はその水溶液で濃度調整を行ってもよい。エキスのエタノール濃度は、30〜95重量%、好ましくは40〜75重量%の範囲にある。エタノール濃度が40重量%より低いと腐敗の虞があり、濃度が75重量%より高くなると、有効成分の一部が析出するので好ましくない。
風味改善剤をエキスの形態で使用する場合、風味改善剤が析出しない濃度であれば特に支障はないが、風味改善剤の濃度は、5〜30重量%、更に10〜20重量%の範囲にあることが好ましい。
The extract dissolved in the low-concentration ethanol aqueous solution is preferably pulverized by spray drying, freeze drying or the like in order to avoid spoilage. Moreover, it can also be granulated using the excipient | filler which does not impair the flavor of food-drinks.
An extract dissolved in a high-concentration ethanol aqueous solution may be used as an extract as it is, but in order to further increase the titer, concentration may be adjusted with ethanol or an aqueous solution thereof after concentration. The ethanol concentration of the extract is 30 to 95% by weight, preferably 40 to 75% by weight. If the ethanol concentration is lower than 40% by weight, there is a risk of spoilage. If the ethanol concentration is higher than 75% by weight, a part of the active ingredient is precipitated, which is not preferable.
When the flavor improving agent is used in the form of an extract, there is no particular problem as long as the flavor improving agent does not precipitate, but the concentration of the flavor improving agent is in the range of 5 to 30% by weight, more preferably 10 to 20% by weight. Preferably there is.
