Description

本発明は、加工食品全般に対して利用しやすい特性を有し、製造コストが安価なマルトオリゴ糖組成物、その製法及び飲食物に関する。   The present invention relates to a maltooligosaccharide composition, a method for producing the same, and foods and drinks that have properties that are easy to use for processed foods in general and are inexpensive to produce.

近年、食品加工技術の発達に伴って、菓子類、デザート類、飲料、乾燥食品、レトルト食品、練り製品等、様々な加工食品が市場に上市されている。これら加工食品の多くには従来から賦型、増量、品質改良、ボディ感の付与、甘味の付与、エネルギー付与等を目的として、水あめやデキストリンが多く使用されている。水あめやデキストリンは、澱粉を酸や酵素で加水分解することによって製造され、分解度や性状(液状又は粉状)により、水あめ、粉あめ、マルトデキストリン、デキストリン等の名称で呼ばれており、加工食品の目的に応じて使用されている。さらに最近では、風味、味質、嗜好性等の多様化、高品質化志向から、より加工食品に使用しやすい素材が求められている。すなわち、低甘味でクセのない味質を有し、適度な粘性を有した素材であるマルトオリゴ糖の需要が高まってきている。   In recent years, with the development of food processing technology, various processed foods such as confectionery, desserts, beverages, dried foods, retort foods, and paste products have been put on the market. Many of these processed foods have been conventionally used in the form of syrup and dextrin for the purpose of shaping, increasing the amount, improving the quality, imparting a feeling of body, imparting sweetness, imparting energy and the like. Water candy and dextrin are produced by hydrolyzing starch with acid or enzyme, and are called by names such as water candy, powder candy, maltodextrin, dextrin, etc., depending on the degree of degradation and properties (liquid or powder) It is used according to the purpose of food. Furthermore, recently, materials that are easier to use in processed foods are being demanded because of the diversification of flavor, taste, and palatability, and high quality. That is, there is an increasing demand for maltooligosaccharides, which are low-sweetness, tasteless, and have a suitable viscosity.

このようなマルトオリゴ糖の製法については種々の技術が開示されている。例えば、澱粉、または澱粉の液化液に、好ましくは枝切り酵素と同時にマルトテトラオースやマルトペンタオース、マルトへキサオース、マルトへプタオース等の生成酵素を作用させ、これらの糖質を高含有したオリゴ糖を製造する方法(特許文献1〜5)、澱粉加水分解物をクロマト分離、膜分離等の分離技術を用いてオリゴ糖成分を分画する方法(特許文献6)、さらには両方法を組み合わせた方法(特許文献7〜10)などがあり、製造方法によって様々な組成のものが存在している。例えば、マルトトリオース(3糖類)を高含有するもの、同様にマルトテトラオース(4糖類)、マルトペンタオース(5糖類)をそれぞれ高含有するもの、さらにはマルトへキサオース、マルトへプタオース(6糖類、7糖類)を主成分とするものなどがあげられ、特定のオリゴ糖成分を高含有することにより、低甘味、低粘度、老化抑制、保湿性等の特性を有するとされている。   Various techniques for producing such maltooligosaccharides have been disclosed. For example, a starch or a liquefied liquid of starch is preferably reacted with a debranching enzyme simultaneously with a production enzyme such as maltotetraose, maltopentaose, maltohexaose, maltoheptaose, and an oligo containing a high content of these sugars. A method for producing sugar (Patent Documents 1 to 5), a method for fractionating oligosaccharide components using a separation technique such as chromatographic separation and membrane separation of starch hydrolysates (Patent Document 6), and a combination of both methods There are various methods (Patent Documents 7 to 10), and various compositions exist depending on the production method. For example, high content of maltotriose (trisaccharide), similarly high content of maltotetraose (4 sugar) and maltopentaose (pentasaccharide), maltohexaose, maltoheptaose (6 Saccharides and heptasaccharides) as main components, and a high content of a specific oligosaccharide component is said to have properties such as low sweetness, low viscosity, anti-aging, and moisture retention.

一方、これらのマルトオリゴ糖を加工食品に利用する場合、マルトオリゴ糖の組成が加工食品に好ましくない影響を与えることがある。例えば、低分子領域のマルトオリゴ糖は、糊感は少ないが甘味が強くボディ感に欠けるなどの問題が、また高分子領域のマルトオリゴ糖は、甘味は低いが糊感があり、高分子成分がゲル形成阻害や離水の要因となるなどの問題が生じることがあり、加工食品の食感や物性を損なう恐れがある。
さらに、これらの先行技術に示されるマルトオリゴ糖組成物を製造するためには、マルトテトラオースやマルトペンタオース、マルトへキサオース、マルトへプタオース等を特異的に生成する特殊な酵素を使用する必要があり、酵素反応も長時間を要する。また、澱粉の加水分解物から、好ましくない成分をクロマト分離装置や膜分離装置を用いて分離、除去して製造されるため、コスト的に高くなる傾向にあった。
On the other hand, when these maltooligosaccharides are used in processed foods, the composition of maltooligosaccharides may adversely affect processed foods. For example, malto-oligosaccharides in the low molecular weight region have problems such as a little sticky feeling but strong sweetness and lack of body feeling. In addition, malto-oligosaccharides in the high molecular weight region have a low sweetness but a sticky feeling, and the polymer component is a gel. Problems such as formation inhibition and water separation may occur, and the texture and physical properties of the processed food may be impaired.
Furthermore, in order to produce the maltooligosaccharide composition shown in these prior arts, it is necessary to use a special enzyme that specifically produces maltotetraose, maltopentaose, maltohexaose, maltoheptaose, etc. Yes, the enzyme reaction also takes a long time. Moreover, since it manufactures by isolate | separating and removing an unfavorable component from the hydrolyzate of starch using a chromatographic separation apparatus or a membrane separation apparatus, it tends to increase in cost.

また、特許文献11には、食品風味を損なうデキストリン特有の風味を低減し、かつ低甘味性を維持したグルコースポリマーとその製造方法についての記載がある。しかしながら、同文献に記載の「DE27以下であり、かつ分子量5,000以上の糖組成物含有量が固形分当たり18重量%以下であり、さらに含まれる単糖類が固形分当たり6重量%以下であることを特徴とするグルコースポリマー」には、市販されているDE=15〜25程度の澱粉加水分解物のほとんどが該当する(例えば、代表的なデキストリンとしてのTK−16、パインデックス#4及びSPD)。そしてこれらの澱粉加水分解物は、上記のマルトオリゴ糖組成物と同様に、糊感、高甘味、高粘性、ゲル形成阻害などが問題となる場合があり、加工食品の食感や物性を損なう恐れがある。また、記載されている製造方法で得られるグルコースポリマーは、製造の第2分解工程で枝切り酵素を使用するためと考えられるが、低温で白濁を起こす性質があり、食品によっては使用が困難となることが予想される。   In addition, Patent Document 11 describes a glucose polymer in which the dextrin-specific flavor that impairs the food flavor is reduced and the low sweetness is maintained, and a method for producing the glucose polymer. However, the content of a sugar composition having a DE of 27 or less and a molecular weight of 5,000 or more described in the same document is 18% by weight or less per solid, and the contained monosaccharide is 6% by weight or less per solid. “Glucose polymer characterized by” includes most commercially available starch hydrolysates having a DE of about 15 to 25 (for example, TK-16 as a typical dextrin, Paindex # 4 and SPD). These starch hydrolysates, like the above-described maltooligosaccharide composition, may cause problems such as pastiness, high sweetness, high viscosity, and inhibition of gel formation, and may impair the texture and physical properties of processed foods. There is. In addition, the glucose polymer obtained by the described production method is thought to be due to the use of a debranching enzyme in the second decomposition step of production, but it has the property of causing white turbidity at low temperatures and is difficult to use depending on food. It is expected to be.

In the present invention, “DE” is a value represented by the formula “[(mass of direct reducing sugar (expressed as glucose)) / (mass of solid content)] × 100”. This is the analysis value.

本発明のマルトオリゴ糖組成物は、澱粉を酸で加水分解した後、α−アミラーゼ、又はα−アミラーゼと枝切り酵素で加水分解することによって調製することができる。詳しくは、澱粉をボーメ18〜22程度のスラリーとした後、塩酸、蓚酸等の酸を加えてpHを1.8〜2.0程度に調整する。次いでオートクレーブ、加熱加圧蒸煮釜等の加熱装置を用いて、100〜130℃に加熱して40分〜80分間程度加水分解を行い、DE=10〜15程度、好ましくは12〜13に液化する。このときのDEが低すぎると高分子成分が多く残り、高粘性や糊感の要因となり、反対に高すぎるとブドウ糖の発生が多くなり、甘味の要因となる。炭酸カルシウム等により中和後、pHを5.5〜6.5程度に調整し、液化型α−アミラーゼを添加して80〜95℃で30〜80分程度、酵素反応を行い、DE=20〜25に加水分解した後、温度を130℃まで上げるか、蓚酸などの酸を用いてpHを3.5以下に調整してα−アミラーゼの酵素作用を終了させる。この液化型α−アミラーゼとしては市販品、例えばクライスターゼKM(大和化成(株)社製)やターマミル120L(ノボザイムズジャパン社製)などが使用できる。酵素の失活に酸を用いた場合は、炭酸カルシウムなどの中和剤でpHを5〜6に調整する。   The maltooligosaccharide composition of the present invention can be prepared by hydrolyzing starch with acid and then hydrolyzing with α-amylase, or α-amylase and a debranching enzyme. Specifically, after the starch is made into a slurry of about 18-22 Baume, an acid such as hydrochloric acid or oxalic acid is added to adjust the pH to about 1.8-2.0. Next, using a heating device such as an autoclave or a heating and pressure cooking kettle, the mixture is heated to 100 to 130 ° C. and hydrolyzed for about 40 to 80 minutes, and liquefied to DE = 10 to 15, preferably 12 to 13 . If the DE at this time is too low, a large amount of polymer components remain, causing high viscosity and a feeling of paste, while if it is too high, glucose is generated more and causes sweetness. After neutralization with calcium carbonate or the like, the pH is adjusted to about 5.5 to 6.5, liquefied α-amylase is added, and an enzyme reaction is performed at 80 to 95 ° C. for about 30 to 80 minutes. DE = 20 After hydrolysis to ˜25, the temperature is raised to 130 ° C. or the pH is adjusted to 3.5 or lower using an acid such as succinic acid to terminate the enzymatic action of α-amylase. As this liquefied α-amylase, commercially available products such as Christase KM (manufactured by Daiwa Kasei Co., Ltd.) and Termamyl 120L (manufactured by Novozymes Japan) can be used. When an acid is used for enzyme deactivation, the pH is adjusted to 5-6 with a neutralizing agent such as calcium carbonate.

本発明のマルトオリゴ糖組成物の原料として使用する澱粉は、特に制限されない。例えば、タピオカ澱粉、コーンスターチ、馬鈴薯澱粉、甘藷澱粉、小麦澱粉、米澱粉、サゴ澱粉、等が挙げられる。   The starch used as a raw material of the maltooligosaccharide composition of the present invention is not particularly limited. Examples include tapioca starch, corn starch, potato starch, sweet potato starch, wheat starch, rice starch, and sago starch.

また、本発明のマルトオリゴ糖組成物は、前記酸分解後、液化型α−アミラーゼでDEを15〜20程度としてpHを4〜5に調整した後、さらに枝切り酵素、または枝切り酵素と糖化型α−アミラーゼによってDE=20〜25に加水分解して製造することもできる。この枝切り酵素、糖化型α−アミラーゼはいずれも市販品が使用できるが、例えば枝切り酵素であればOptimax L−1000(ジェネンコア協和社製)やプロモザイムD2(ノボザイムズジャパン社製)などが、また糖化型α−アミラーゼであれば、ファンガミル800L(ノボザイムズジャパン社製)やビオザイムL(天野エンザイム(株)社製)などがある。その後、活性炭による脱色、イオン交換樹脂による脱塩等によって精製し、濃縮後噴霧乾燥により粉末とするか、75質量%程度に濃縮して液状品とする。さらに、澱粉加水分解物をクロマト分離装置や膜分離装置を用いて分画処理を行ない、分子量特性値Bが0.8〜1.5の範囲を外れない程度に、高分子成分や低分子成分を分離除去しても良い。   In addition, the maltooligosaccharide composition of the present invention, after acid decomposition, after adjusting pH to 4-5 with DE of about 15-20 with liquefied α-amylase, and further saccharifying with debranching enzyme or debranching enzyme It can also be produced by hydrolyzing to DE = 20-25 with a type α-amylase. Commercially available products of this debranching enzyme and saccharified α-amylase can be used. For example, Optimax L-1000 (Genencor Kyowa Co., Ltd.) and Promozyme D2 (Novozymes Japan Co., Ltd.) can be used. In addition, for saccharified α-amylase, there are Fangamyl 800L (manufactured by Novozymes Japan) and Biozyme L (manufactured by Amano Enzyme). Then, it is purified by decolorization with activated carbon, desalting with an ion exchange resin, and the like, and after concentration, it is powdered by spray drying or concentrated to about 75% by mass to obtain a liquid product. Furthermore, the starch hydrolyzate is subjected to fractionation using a chromatographic separation device or a membrane separation device, so that the molecular weight characteristic value B does not deviate from the range of 0.8 to 1.5. May be separated and removed.

このようにして得られるマルトオリゴ糖組成物は、(1)70質量%、30℃における粘度が1000mPa・s以下であり、(2)甘味度が25以下であり、(3)分子量10,000を超える成分の割合が3質量%以下で、分子量1,000以下の成分の分子量1,000〜10,000成分に対する比が0.8〜1.5の範囲であり、さらに、(4)糖組成中のオリゴ糖(2糖類〜10糖類)の割合が65質量%以上であるという全ての要件を満たす。
甘味度、粘度が上記の値よりも高いと甘味が高く食感的にも糊感が強くなり、さらに粘度的に取り扱いが不便となり好ましくない。さらに分子量の特性値と糖組成が上記の範囲から外れると、低分子成分や高分子成分の比率が高くなり、組成的に均一性が欠けてくるため、味質や風味発現性が悪くなったりゲル形成阻害を起こすなど、食品の食感や物性に対して好ましくない影響を与えてしまう。
The maltooligosaccharide composition thus obtained has (1) 70% by mass, a viscosity at 30 ° C. of 1000 mPa · s or less, (2) a sweetness level of 25 or less, and (3) a molecular weight of 10,000. The ratio of the component exceeding 3% by mass and the ratio of the component having a molecular weight of 1,000 or less to the molecular weight of 1,000 to 10,000 is in the range of 0.8 to 1.5, and (4) sugar composition All the requirements that the ratio of the oligosaccharide (2 saccharides to 10 saccharides) is 65% by mass or more are satisfied.
If the sweetness level and viscosity are higher than the above values, the sweetness is high and the feeling of paste is strong, and the handling is inconvenient in terms of viscosity. Furthermore, if the molecular weight characteristic value and the sugar composition are out of the above ranges, the ratio of the low molecular component and the high molecular component increases, and the composition is not uniform, resulting in poor taste quality and flavor expression. Unfavorable effects on food texture and physical properties such as gel formation inhibition.
