Description
本発明は、固形分を含む溶液の精製方法及びその装置に関する。 The present invention relates to a method for purifying a solution containing a solid content and an apparatus thereof.
近年、健康に対する関心の高まりから食物繊維の摂取に対する関心が高まっており、果汁飲料、野菜飲料においても清澄していないタイプの製品が多くなってきている。 In recent years, there has been an increase in interest in dietary fiber intake due to an increase in interest in health, and the number of unclear type products in fruit juice beverages and vegetable beverages is increasing.
ところで、飲料の原料となる果汁や野菜には、本来の呈味、香気成分、ビタミン等の有用成分だけでなく、青臭さや刺激臭等好ましくない臭気や、カフェイン等の過剰に摂取することが好ましくない成分（不要成分）、不純物等が含まれており、これらを除去した製品化が必要とされている。また、場合によっては色等の低減も必要となることがある。液相中の臭いや夾雑成分、色の除去のためには、通常活性炭や活性白土、シリカゲル、イオン交換樹脂、脱色樹脂等の吸着剤が使用されるが、粉末状の吸着剤を使用する場合はろ過工程が必要となり、その際、飲料中の懸濁成分（有用成分）も同時に除かれてしまい、清澄な製品しか得られなくなる。また、破砕状、球状、ペレット状といった粒状の吸着剤を用いると、通液中に懸濁物質（有用成分）が粒子間に目詰まりしてしまい、処理の継続が困難になるという課題があった。このため、果汁飲料、野菜飲料から、実質的に有用成分を除去せずに臭気、不要成分、不純物のみを除去することは、本質的に困難であった。 By the way, fruit juices and vegetables, which are the raw materials for beverages, may ingest not only useful components such as original taste, aroma components, and vitamins, but also unfavorable odors such as green odor and pungent odor, and excessive intake of caffeine and the like. It contains undesired components (unnecessary components), impurities, etc., and commercialization with these removed is required. In some cases, it may be necessary to reduce the color and the like. Adsorbents such as activated carbon, activated clay, silica gel, ion exchange resin, and decolorizing resin are usually used to remove odors, contaminants, and colors in the liquid phase, but when powdered adsorbents are used. Requires a filtration step, and at that time, the suspended components (useful components) in the beverage are also removed at the same time, and only a clear product can be obtained. In addition, if granular adsorbents such as crushed, spherical, and pellet-shaped are used, suspended solids (useful components) will be clogged between the particles during liquid passage, and there is a problem that it is difficult to continue the treatment. rice field. Therefore, it is essentially difficult to remove only odors, unnecessary components, and impurities from fruit juice drinks and vegetable drinks without substantially removing useful components.
そこで、飲料の原料に他の成分を添加することにより風味、臭気を改善する（まぎらわせる）方法が提案されている。たとえば、エリスリトールを共存させることによる臭気のマスキング方法が提案されている（例えば、特許文献１参照）。特に子供向けの菓子類に有臭野菜汁を利用するため、有香果実の果汁を加えてマスキングすることで嗜好性を改善する方法が提案されている（例えば、特許文献２参照）。さらに青汁においては、特定品種の六条大麦の葉を用いて呈色性や風味を改善する方法が提案されている（例えば、特許文献３参照）。 Therefore, a method of improving (misleading) the flavor and odor by adding other components to the raw material of a beverage has been proposed. For example, a method of masking an odor by coexisting with erythritol has been proposed (see, for example, Patent Document 1). In particular, in order to use odorous vegetable juice for confectionery for children, a method of improving palatability by adding fruit juice of fragrant fruit and masking has been proposed (see, for example, Patent Document 2). Further, for green juice, a method for improving coloration and flavor by using leaves of a specific variety of six-rowed barley has been proposed (see, for example, Patent Document 3).
しかしながら、提案されている方法ではマスキングのために別成分を添加することから本来の栄養バランス、風味が本来の組成と変わる可能性があるし、特許文献３に記載のような特定の材料を用いる呈色性、風味改善では検討のために多くの組合せによる検討が必要であり、せっかくの有用な飲料がなかなか商品として成立しえないという課題もあった。 However, in the proposed method, since another component is added for masking, the original nutritional balance and flavor may change from the original composition, and a specific material as described in Patent Document 3 is used. In order to improve coloration and flavor, it is necessary to study many combinations for study, and there is also a problem that it is difficult to establish a useful beverage as a commercial product.
このため、本発明は、栄養バランス、風味等を損なわないために別成分を添加せずとも、固形分を含む溶液から臭気、不要成分、不純物等を取り除くための精製方法及びその装置を提供することを目的とする。 Therefore, the present invention provides a purification method and an apparatus thereof for removing odors, unnecessary components, impurities, etc. from a solution containing solid content without adding another component so as not to impair nutritional balance, flavor, etc. The purpose is.

In the present invention
Separation step, which separates a solution containing solids into a concentrated solution containing a large amount of solids and a filtrate.
By performing a purification step of purifying the filtrate and a mixing step of mixing the refined filtrate with the concentrate, another component can be added so as not to impair the nutritional balance, flavor, etc. At least, odors, unnecessary components, impurities and the like can be removed from the solution containing the solid content without removing useful components.
本発明において、原料として使用する固形分を含む溶液としては、様々な溶液が適用できるが、野菜飲料、果汁飲料、穀物搾汁等のように、飲用溶液に特に適している。野菜飲料の原料野菜としてはケール等の青菜類、トマト等の実、にんじん等の根菜類が挙げられ、果汁の原料果実としては、りんご、なし、みかん、パイナップル等が挙げられ、穀物搾汁の原料穀物としては稲、麦、小麦、トウモロコシ等が挙げられる。これらの溶液は、単独で用いてもよく、2種以上を組合せて用いてもよい。これらの溶液の固形分含有量は特に限定されず、固形分を構成する粒子の大きさも、本発明の方法が、濃縮液とろ液を分離後ろ液を精製し濃縮液と混合する方法であることから限定されることはない。 In the present invention, various solutions can be applied as the solution containing a solid content used as a raw material, but it is particularly suitable for a drinking solution such as a vegetable drink, a fruit juice drink, and a grain juice. Examples of raw vegetables for vegetable drinks include green vegetables such as kale, fruits such as tomatoes, and root vegetables such as carrots. Examples of raw fruits for fruit juice include apples, pears, oranges, and pineapples. Examples of raw material grains include rice, wheat, wheat and corn. These solutions may be used alone or in combination of two or more. The solid content of these solutions is not particularly limited, and the size of the particles constituting the solid content is also the method of the present invention in which the concentrate and the filtrate are separated, and the back liquid is purified and mixed with the concentrate. Not limited to.
本発明において、まず、分離工程として、固形分の多い濃縮液とろ液とに分離する。この分離方法は、特に制限されず、ろ過機により、固形分の多い濃縮液とろ液とに分離することができる。 In the present invention, first, as a separation step, a concentrated solution having a high solid content and a filtrate are separated. This separation method is not particularly limited, and a concentrated solution and a filtrate having a high solid content can be separated by a filter.
分離工程において使用できるろ過機としては、単板式ろ過機、多段ろ過機、遠心ろ過機、遠心分離機（ろ過機以外の手段）、ディスク式回転ろ過機等が挙げられる。濃縮液の排出及びろ過効率の観点から、連続式のろ過機が好ましく、遠心ろ過機、ディスク式回転ろ過機等が好ましく、特に目詰まりを起こし難く、ろ過効率が高いことからディスク式回転ろ過機がより好ましい。 Examples of the filter that can be used in the separation step include a single plate type filter, a multi-stage filter, a centrifugal filter, a centrifuge (means other than the filter), a disk type rotary filter, and the like. From the viewpoint of discharge of concentrated liquid and filtration efficiency, a continuous filter is preferable, a centrifugal filter, a disk-type rotary filter, etc. are preferable, and a disk-type rotary filter is particularly difficult to cause clogging and has high filtration efficiency. Is more preferable.
本発明において、分離工程において使用できるろ過機の濃縮性能としては、特に制限されない。ただし、本発明によれば、ろ液のみを精製するため、より確実に臭気、不要成分、不純物等を除去する観点からは濃縮液中に残存する液体成分は少ない方が好ましい。このような観点から、
一般式１：濃縮比率＝（回収したろ液質量＋濃縮液質量）÷濃縮液質量
で計算した場合、分離手段において精製される濃縮液において、固形分の濃縮比率は4以上が好ましく、6以上がより好ましい。なお、固形分の濃縮比率の上限値は特に制限はないが、通常20である。
In the present invention, the concentration performance of the filter that can be used in the separation step is not particularly limited. However, according to the present invention, since only the filtrate is purified, it is preferable that the amount of liquid components remaining in the concentrated solution is small from the viewpoint of more reliably removing odors, unnecessary components, impurities and the like. From this point of view
General formula 1: Concentration ratio = (Recovered filtrate mass + Concentrate mass) ÷ Concentrate mass In the concentrate purified by the separation means, the solid content concentration ratio is preferably 4 or more, and 6 or more. Is more preferable. The upper limit of the solid content concentration ratio is not particularly limited, but is usually 20.
このようにして濃縮液とろ液とに分離した後、ろ液に精製処理を施す（精製工程）。濃縮液は、有効成分濃度が高められており、また、溶液が少ないために臭気、不要成分、不純物量は少ない。一方、ろ液中には、臭気、不要成分、不純物等が相当程度含まれているため、ろ液を精製することにより、臭気、不要成分、不純物等を除去することができる。このような臭気、不要成分、不純物等の除去工程は連続式であってもよいし、装置内にタンクを設置してバッチ式に処理してもよい。 After separating into the concentrate and the filtrate in this way, the filtrate is purified (purification step). The concentrated solution has a high concentration of active ingredients, and since the amount of solution is small, the amount of odor, unnecessary components, and impurities is small. On the other hand, since the filtrate contains a considerable amount of odors, unnecessary components, impurities and the like, the odors, unnecessary components, impurities and the like can be removed by purifying the filtrate. The step of removing such odors, unnecessary components, impurities and the like may be a continuous process, or a tank may be installed in the apparatus and the process may be performed in a batch system.
ろ液を精製する方法としては、特に制限はなく、例えば、吸着剤によりろ液中の臭気、不要成分、不純物等を吸着することが挙げられる。この際使用できる吸着剤としては、特に制限はなく、種々様々な吸着剤を使用することができ、例えば、活性炭、活性白土、シリカゲル、アルミナ、脱色樹脂、イオン交換樹脂等通常用いられる吸着剤が挙げられる。これらの吸着剤は、単独で用いることもでき、2種以上を組合せて用いることもできる。なかでも、脱臭及び不要成分の除去能力の観点からは活性炭が好ましい。吸着剤の形状は、粒状、粉末状及び繊維状のいずれも採用できる。たとえば、本発明の吸着剤が活性炭からなる場合、粒状活性炭、粉末状活性炭及び繊維状活性炭のいずれも採用できる。また、吸着剤のサイズも特に制限されず、除去しようとする臭気、不要成分、不純物等の大きさによって適宜調整することができる。また、フィルター状等に成形した吸着剤を使用することも可能である。ろ液に吸着剤を接触させる温度は特に制限はなく、冷却下、常温下及び加温下のいずれも採用でき、10～50℃等が採用でき、通常は常温とすることができる。また、ろ液に吸着剤を接触させる時間も特に制限はなく、1分～24時間程度とすることができる。この精製処理は、1回のみ行うこともできるし、複数回繰り返すことも可能である。処理後は、必要に応じてろ液から吸着剤を除去することにより、精製されたろ液を得ることができる。 The method for purifying the filtrate is not particularly limited, and examples thereof include adsorbing odors, unnecessary components, impurities and the like in the filtrate with an adsorbent. The adsorbent that can be used at this time is not particularly limited, and various adsorbents can be used. For example, commonly used adsorbents such as activated carbon, activated clay, silica gel, alumina, decolorizing resin, and ion exchange resin can be used. Can be mentioned. These adsorbents can be used alone or in combination of two or more. Of these, activated carbon is preferable from the viewpoint of deodorizing and removing unnecessary components. The shape of the adsorbent can be granular, powdery or fibrous. For example, when the adsorbent of the present invention is made of activated carbon, any of granular activated carbon, powdered activated carbon and fibrous activated carbon can be adopted. Further, the size of the adsorbent is not particularly limited, and can be appropriately adjusted depending on the size of the odor, unnecessary components, impurities, etc. to be removed. It is also possible to use an adsorbent molded into a filter shape or the like. The temperature at which the adsorbent is brought into contact with the filtrate is not particularly limited, and can be used under cooling, at room temperature, or under heating, at 10 to 50 ° C., and usually at room temperature. Further, the time for contacting the adsorbent with the filtrate is not particularly limited, and can be about 1 minute to 24 hours. This purification process can be performed only once or repeated multiple times. After the treatment, a purified filtrate can be obtained by removing the adsorbent from the filtrate as needed.
このようにしてろ液を精製した後、分離工程で得た濃縮液と混合することにより、精製した溶液を得ることができる。混合方法は特に制限されず、常法にしたがうことができる。 After purifying the filtrate in this way, the purified solution can be obtained by mixing with the concentrated solution obtained in the separation step. The mixing method is not particularly limited and can follow a conventional method.
以上のようにして、固形分を含む溶液に別成分を添加せずとも、有効成分を除去することなく臭気、不要成分、不純物等を除去することが可能である。上記した分離工程、精製工程及び混合工程は、それぞれ1回のみ行うこともできるし、分離工程、精製工程及び混合工程を1セットとして複数回繰り返すことも可能である。 As described above, it is possible to remove odors, unnecessary components, impurities and the like without removing the active ingredient without adding another component to the solution containing the solid content. The separation step, the purification step, and the mixing step described above can be performed only once, or the separation step, the purification step, and the mixing step can be repeated a plurality of times as one set.
