Definitions
- the present invention relates to a method for producing plant-based food and drink. More specifically, the present invention relates to techniques for reducing sugars in plant-based food and drink using maltotriose synthase.
- oat beverages are prepared by suspending the oat material in an aqueous medium and using one or more amylases to break down the starch in the oat material.
- the amylase used at this time is ⁇ -amylase or a mixture of ⁇ -amylase and ⁇ -amylase.
- the oat beverage prepared by this method exhibits moderate sweetness due to the production of maltose by the action of ⁇ -amylase (Patent Document 1).
- a maltotriose synthase is an enzyme that catalyzes a reaction that hydrolyzes oligosaccharides contained in starch into maltotriose units.
- a maltotriose synthase is known to be used for the production of maltotriose syrup (Patent Document 2).
- Carbohydrate oxidase is an enzyme that has the property of oxidizing carbohydrates.
- Carbohydrate oxidase is known to be used for the production of sugar acids represented by maltobionic acid (Patent Document 3).
- Vegetable foods and drinks such as oat beverages contain large amounts of sugars represented by glucose and maltose. Therefore, the demand for sugar reduction has not been met.
- the main purpose of this technology is to provide a technology for reducing sugars in plant-based food and drink.
- the inventors of the present application have conducted intensive research on techniques for reducing sugars in plant-based food and drink. We discovered that it is possible to reduce the amount of sugar in the product, and completed this technology.
- the present technology provides a method for producing a plant-based food or drink, which includes a step of allowing a maltotriose-generating enzyme to act on a plant-based raw material.
- a maltotriose-generating enzyme to act on a plant-based raw material.
- a raw material treated with ⁇ -amylase can be used.
- a step of allowing carbohydrate oxidase to act on the plant raw material can be further performed.
- oat milk can be produced as a vegetable food or drink.
- the present technology also provides a saccharide-reducing enzymatic agent containing a maltotriose synthase.
- the saccharide-reducing enzymatic agent according to the present technology can further contain saccharide oxidase.
- the present technology further provides a method for reducing sugars in plant-based foods and drinks, which includes a step of allowing a maltotriose-generating enzyme to act on plant-based raw materials.
- sucrose is a generic term for monosaccharides and disaccharides.
- Method for producing plant-based food and drink, method for reducing sugars in plant-based food and drink> A method for producing a plant-based food and drink and a method for reducing sugars in a plant-based food and drink according to the present technology include a step of allowing a maltotriose-generating enzyme to act on a plant-based raw material (hereinafter also referred to as a “maltotriose-generating enzyme acting step”).
- carbohydrate oxidase acting process the process of causing carbohydrate oxidase to act on the plant raw material
- ⁇ -amylase acting process the process of causing ⁇ -amylase to act on the plant raw material
- the recovery step of recovering the manufactured plant-based food and drink and the plant-based food and drink with reduced sugars is further can also be implemented. Each step will be described in detail below.
- Plant-based raw materials The plant-based raw materials that can be used in this technology are not particularly limited in origin, type, etc., as long as they do not impair the effects of this technology. , can be freely selected.
- legumes such as soy beans, green peas, lentils, chickpeas, black beans, fava beans, mung beans, lupine beans, kidney beans; wheat, barley , oats, rice, rye, buckwheat, millet, millet, and teff; Nuts such as pine nuts; hemp seeds (industrial hemp), chia seeds (Chia), Quinoa, amaranth (Amaranthus), canary seed, linseed and the like. In the present technology, these may be used alone, or two or more of them may be used in combination. Among these raw materials, cereals are preferred, and oats are more preferred.

[でんぷん糖化力活性測定法:マルトトリオース生成酵素の活性測定方法]
基質とする溶性デンプンに酵素を作用させ、生じた還元糖をソモギー・ネルソン法により比色定量した。
50mLネスラー管に溶性デンプン溶液0.5mL及び0.1mol/L酢酸・酢酸ナトリウム緩衝液(pH6.0)(0.05mol/LCaCl2を含む)を0.4mL量り、よく振り混ぜ40±0.5℃で10~15分間放置した後、試料溶液0.1mLを加え、直ちに振り混ぜた。この液を40±0.5℃で正確に15分間放置した後、アルカリ性銅試液を1mL加え、振り混ぜて栓をし、沸騰水浴中で正確に20分間加熱し、直ちに冷却した。冷却後、ネルソン液1mLを加え、亜酸化銅の赤色沈殿が完全に溶けるまでよく振り混ぜた後、室温で20分間放置し、水を22mL加え、よく振り混ぜた。この液につき水を対照として、波長520nmにおける吸光度を測定した。1分間に1μmolのブドウ糖に相当する還元糖を生成するときを1単位とした。
適当量の酵素を量り、冷却したpH7.0のリン酸カリウム・水酸化ナトリウム緩衝液(0.1mol/L)を加えて溶解又は均一に分散して50mLとしたものを試料液とした。D(+)-グルコース2.50gを量り、水を加えて溶かし、25mLとしたものを基質溶液とした。基質溶液0.5mL、リン酸カリウム・水酸化ナトリウム緩衝液(0.1mol/L、pH7.0、フェノール含有)2mL、パーオキシダーゼ試液(25単位/mL)0.5mL及び4-アミノアンチピリン溶液(1→250)0.1mLを石英セルに入れ、37℃で10分間加温した。この液に試料液0.1mLを加えてよく混ぜて37℃で加温し、検液とした。別に試料液の代わりにpH7.0のリン酸カリウム・水酸化ナトリウム緩衝液(0.1mol/L)又は水を用いて検液の調製と同様に操作し、比較液とした。検液及び比較液につき、試料液添加2分後及び5分後の波長500nmにおける吸光度を測定した。生成したキノンイミン色素のモル吸光係数から酸化されたグルコース量を定量した。条件下、1分間に1μmolのグルコースを酸化するのに必要な酵素量を1単位とした。
<実験例1>
実験例1では、マルトトリオース生成酵素による糖類低減効果を調べた。
ビーカーにオートフラワー(スローフードキッチンPTEMIUM OAT FLOUR)を12.5g計り取り、液量が100mLになるように水を加えた。そこにα-アミラーゼを0.5(w/wオートフラワー)%、マルトトリオース生成酵素をオートフラワー1g当たり12U加え、60℃水浴中に入れ、溶液の温度が60℃に達した後、2時間静置した。その後、煮沸水浴中に入れ10分間静置し酵素を失活させオート飲料を調製した。マルトトリオース生成酵素をβ-アミラーゼ0.3(w/wオートフラワー)%に置き換えたものをコントロールとした。
表1に示す通り、β-アミラーゼ処理したオート飲料及び市販のオートミルクの糖類含有量は、いずれも27mg/mL以上であった。一方、マルトトリオース生成酵素を使用することで、糖類の量を20mg/mL以下にできることが確認された。
実験例2では、糖質酸化酵素による糖類低減効果を確認した。
実施例1の方法に準じて、マルトトリオース生成酵素を使用したオート飲料を調製し、200mL計り取り500mL容三角フラスコに入れた。そこに、Acremonium chrysogenum由来の糖質酸化酵素をグルコースオキシダーゼ活性が600単位となるように添加、三角フラスコを40℃水浴中に入れ、2mm径のチューブで適度な空気を送りながら撹拌し2時間反応させた。酵素反応後のオート飲料を煮沸水浴中に入れ10分間静置し酵素を失活させた。失活させたオート飲料に既定の処理を行い、ICSep ICE-ION-300 column(Transgenomic Inc., New Haven,CT,USA)を用いてHPLCで生成した糖を分析した。
実験例3では、α-アミラーゼ作用工程を、マルトトリオース生成酵素作用工程前に、行った場合、更に、各種酵素作用条件を変更した場合の効果について確認した。
ビーカーにオートフラワー(スローフードキッチンPTEMIUM OAT FLOUR)を12.5g計り取り、液量が100mLになるように水を加えた。そこにα-アミラーゼを0.5(w/wオートフラワー)%加え、60℃水浴中に入れ、溶液の温度が60℃に達した後、2時間静置した。その後、煮沸水浴中に入れ10分間静置し酵素を失活させオート飲料原料を調製した。オート飲料原料に、マルトトリオース生成酵素をオートフラワー1g当たり1.2~120U加え、40℃又は50℃水浴中に入れ、溶液の温度が60℃に達した後、1~3時間静置した。その後、煮沸水浴中に入れ10分間静置し酵素を失活させオート飲料を調製した。
表3および表4に示す通り、α-アミラーゼ処理後にマルトトリオース生成酵素処理をした場合でも、糖類低減効果が確認できた。また、マルトトリオース生成酵素の添加量、処理温度、処理時間を変えた場合でも、糖類低減効果が確認できた。
