Description

本発明は、コラーゲンペプチドの不快な臭いを除去する方法及びそれを利用した飲食品に関するものである。   The present invention relates to a method for removing an unpleasant odor of a collagen peptide and a food or drink using the method.

近年、肌に対する美容効果が期待されるコラーゲンペプチドの摂取を目的とした飲食品が数多く上市されている。コラーゲンペプチドを含めた市販のコラーゲン素材にはコラーゲン臭ともゼラチン臭とも表現されるような独特の不快な臭いがある。そしてコラーゲンペプチドの摂取を目的とした飲食品においては、その独特の不快な臭いのために嗜好性が上がらず、購買意欲を削ぐ要因となっている。コラーゲンを多く含む食品としては、フカヒレ、魚の煮こごり、豚足といったものが挙げられ、これらにもコラーゲン臭は存在するが、これらについては料理を構成する要素として許容されている。しかし中には、このコラーゲン臭を好まないためにこれらの食品であっても食せない人も存在する。そして、コラーゲンペプチドの摂取を目的とした飲食品の場合には、飲料やゼリー、タブレット等の形態で摂る場合が多く、コラーゲンが含まれる食材を使った料理よりもコラーゲン臭による違和感や不快感を感じ易いという問題がある。   In recent years, many foods and drinks have been put on the market for the purpose of ingesting collagen peptides that are expected to have a cosmetic effect on the skin. Commercially available collagen materials including collagen peptides have a unique and unpleasant odor that can be expressed as both a collagen odor and a gelatin odor. And in foods and drinks for the purpose of ingesting collagen peptides, the peculiar unpleasant odor does not improve the palatability, which is a factor in reducing the willingness to purchase. Examples of foods rich in collagen include shark fin, stewed fish, and pork leg, which also have a collagen odor, but these are allowed as a component of cooking. However, some people do not like this collagen odor and cannot eat even these foods. And in the case of foods and drinks for the purpose of ingesting collagen peptides, they are often taken in the form of beverages, jelly, tablets, etc. There is a problem that it is easy to feel.

コラーゲン素材の不快な臭いに対応する方法がいくつか公知となっている。特許文献1には、甘味料を添加することでコラーゲンを摂取しやすくすることが開示されている。しかしながら、これは臭いをマスキングするのみであり、臭いの成分自体に作用するものではない。   Several methods for dealing with the unpleasant odor of collagen materials are known. Patent Document 1 discloses that a collagen can be easily ingested by adding a sweetener. However, this only masks the odor and does not affect the odor component itself.

特許文献2には、コラーゲン製品を製造する何れかの段階において、コラーゲンの機械的特性を改善するものであるコラーゲンの架橋処理を同時に行うことができる活性物質を使用して脱臭処理が施されたものであるコラーゲン製品が開示されている。これは、架橋処理によりコラーゲンの物性が変化するものであり、また化粧品や医薬製品に用いられるものである。   In Patent Document 2, deodorization treatment was performed using an active substance capable of simultaneously performing a crosslinking treatment of collagen, which improves the mechanical properties of collagen, at any stage of producing a collagen product. A collagen product is disclosed. This changes the physical properties of collagen by crosslinking treatment, and is used for cosmetics and pharmaceutical products.

特許文献3には魚皮及び/又は魚骨の抽出物の酵素分解物を逆浸透膜処理して得られる、固形分中の遊離アミノ酸含量が1.0質量%以下、ヒ素含量が2ppm以下であるコラーゲンペプチドが開示されている。これは、主に遊離アミノ酸を除去するものであると考えられ、逆浸透膜処理工程も必要となる。

Patent Document 3 discloses that a free amino acid content in a solid content obtained by subjecting an enzymatic degradation product of fish skin and / or fish bone extract to reverse osmosis membrane treatment is 1.0 mass% or less and an arsenic content is 2 ppm or less. Certain collagen peptides have been disclosed. This is considered to mainly remove free amino acids, and a reverse osmosis membrane treatment step is also required.

本発明は、簡便な方法でコラーゲンペプチドの不快臭成分を除去する方法、及びそれにより得られたコラーゲンペプチドを利用した飲食品を提供することを課題とした。   An object of the present invention is to provide a method for removing an unpleasant odor component of a collagen peptide by a simple method and a food or drink using the collagen peptide obtained thereby.

本発明は、コラーゲンペプチドを少量のエタノールと共に加熱することで、その不快臭成分であるメタンチオール及びジメチルジスルフィドを減少させることができるとの知見によるものである。すなわち本発明は、以下に示されるものである。
(1) コラーゲンペプチドとエタノールが含まれる水溶液を加熱することを特徴とする、コラーゲン臭の除去方法。
(2) コラーゲンペプチドとエタノールが含まれる水溶液中のエタノールがコラーゲンペプチドに対して0.5重量%以上であり、かつ、該水溶液のエタノール含量が10重量%以下である(1)に記載のコラーゲン臭の除去方法。
(3) 60〜140℃に加熱するものである(1)又は(2)に記載のコラーゲン臭の除去方法。
(4) 70〜90℃で3〜30分間加熱するものである(1)〜(3)の何れかに記載のコラーゲン臭の除去方法。
(5) コラーゲンペプチドが魚由来である(1)〜(4)の何れかに記載のコラーゲン臭の除去方法。
(6) (1)〜(5)の何れかに記載の方法により消臭されたコラーゲンペプチド。
(7) (6)に記載のコラーゲンペプチドを含有した飲食品。
The present invention is based on the knowledge that the unpleasant odor components methanethiol and dimethyl disulfide can be reduced by heating the collagen peptide with a small amount of ethanol. That is, the present invention is as follows.
(1) A method for removing a collagen odor, comprising heating an aqueous solution containing a collagen peptide and ethanol.
(2) The collagen according to (1), wherein the ethanol in the aqueous solution containing the collagen peptide and ethanol is 0.5% by weight or more with respect to the collagen peptide, and the ethanol content of the aqueous solution is 10% by weight or less. Odor removal method.
(3) The method for removing a collagen odor according to (1) or (2), wherein the method is heated to 60 to 140 ° C.
(4) The method for removing a collagen odor according to any one of (1) to (3), wherein heating is performed at 70 to 90 ° C. for 3 to 30 minutes.
(5) The method for removing a collagen odor according to any one of (1) to (4), wherein the collagen peptide is derived from fish.
(6) A collagen peptide deodorized by the method according to any one of (1) to (5).
(7) A food or drink containing the collagen peptide according to (6).

本発明により、簡便にコラーゲンペプチドの不快臭を減じることができ、コラーゲン臭の苦手な人にとっても親しみやすい、コラーゲンペプチドを含む飲食品を提供することができる。   According to the present invention, an unpleasant odor of a collagen peptide can be easily reduced, and a food or drink containing a collagen peptide that can be easily familiar to those who are not good at collagen odor can be provided.

本発明のコラーゲン臭の除去方法においては、まずコラーゲンペプチドを溶解した水溶液を準備し、それにエタノールもしくはエタノールを含む原料を添加する。コラーゲンペプチドとは、魚や牛、豚の皮等に大量に含まれるコラーゲンを加水分解して低分子化し、体内で吸収しやすくしたものを言う。エタノールを含む原料は、ビール、ワイン、焼酎、日本酒、ウイスキー、ブランデー等の酒類やみりんがよい。エタノールは、コラーゲンペプチドに対して0.5重量%以上であるのが好ましい。これを下回ると充分な不快臭低減効果が得られない。また、当該水溶液中のエタノール濃度は、10重量%以下であることが好ましい。10重量%を越えると製造中またはその後に沈殿が生じる危険性があるので好ましくない。そして必要に応じて、果汁や甘味料、酸味料、香料等を加えても構わない。   In the method for removing a collagen odor of the present invention, first, an aqueous solution in which a collagen peptide is dissolved is prepared, and ethanol or a raw material containing ethanol is added thereto. Collagen peptides are those that hydrolyze and reduce the molecular weight of collagen contained in large amounts in fish, cattle, pig skin, etc., and make it easier to absorb in the body. The raw material containing ethanol is preferably beer, wine, shochu, sake, whiskey, brandy and other alcoholic beverages and mirin. Ethanol is preferably 0.5% by weight or more based on the collagen peptide. Below this value, a sufficient unpleasant odor reducing effect cannot be obtained. In addition, the ethanol concentration in the aqueous solution is preferably 10% by weight or less. Exceeding 10% by weight is not preferred because there is a risk of precipitation during or after production. And as needed, you may add fruit juice, a sweetener, a sour agent, a fragrance | flavor, etc.

次にこれを好ましくは60〜140℃に加熱する。60℃を下回ると充分に不快臭が除去できない。また、140℃にてUHT殺菌をしても効果的であるが、これ以上温度が高いと加熱時間が極端に短くなるので、品質にバラツキが生じるおそれがあり、品質管理上好ましくない。そしてより好ましくは70〜90℃で3〜30分間程度保持するのがよい。   This is then preferably heated to 60-140 ° C. If it is below 60 ° C., the unpleasant odor cannot be removed sufficiently. Moreover, although it is effective even if UHT sterilization is performed at 140 ° C., if the temperature is higher than this, the heating time is extremely shortened, and therefore there is a possibility that the quality may vary, which is not preferable in terms of quality control. And more preferably, it is good to hold | maintain at 70-90 degreeC for about 3 to 30 minutes.

上記の処理により、コラーゲンペプチドの香気成分のうち特に、イオウ化合物であり、発酵臭を呈するメタンチオール及びジメチルジスルフィドを顕著に減少させることができる。なお本発明は、豚、牛、鶏等を由来とするコラーゲン素材にも使用できるが、特に魚由来のコラーゲンペプチドの消臭に好ましく使用できる。コラーゲンペプチドを抽出する魚としては、例えばサケ、マス、タラ、サバ、アジ、タイ、ティラピア、スズキ、ニシン等が挙げられ、主にこれらの魚皮や鱗から抽出できる。こうして得られたコラーゲンペプチドを含む水溶液は、コラーゲン含有飲食品の原料としてさらに加工してもよく、そのまま飲料として使用してもよい。
以下、実施例等により本発明をさらに詳細に説明するが、本発明はこれらに限定されるものではない。
By the above treatment, methanethiol and dimethyl disulfide, which are sulfur compounds among the aromatic components of the collagen peptide and exhibit a fermentation odor, can be significantly reduced. In addition, although this invention can be used also for the collagen raw material derived from a pig, a cow, a chicken, etc., it can be preferably used especially for deodorizing the collagen peptide derived from a fish. Examples of fish from which collagen peptides are extracted include salmon, trout, cod, mackerel, horse mackerel, Thailand, tilapia, sea bass, and herring, and can be extracted mainly from these fish skins and scales. The aqueous solution containing the collagen peptide thus obtained may be further processed as a raw material for collagen-containing food or drink, or may be used as it is as a beverage.
