Description

本発明は、殺菌甘酒に関し、更に詳しくは、フィチン酸及び/又はその塩を特定量含有する、褐変、変質の少ない高品質で風味の優れた殺菌甘酒に関するものである。   The present invention relates to a sterilized amazake, and more particularly, to a sterilized amazake that contains a specific amount of phytic acid and / or a salt thereof and has a high quality and excellent flavor with little browning and alteration.

甘酒は、米麹と飯米を混ぜて加温しながら糖化させ、これを湯水で薄め又は酒粕を溶かし、更に所望により食塩やショウガを加えて、飲用する日本古来の伝統的甘味飲料である。この甘酒には、水溶性ビタミン類、ミネラル類、アミノ酸類、有機酸類、及び食物繊維など、各種の成分が含まれており、滋養分に富んだ食品である。
しかし、甘酒を米麹と米飯を混ぜて糖化するためには、長時間所定の温度に保持しなければならず、管理に経験と熟練を要する。しかも、米麹の販売所も少ないため、甘酒を手軽に作ることができず、また、酒粕を溶かして甘酒を作る場合も、一度に大量の甘酒ができてしまい、少量の甘酒を手軽に作ることができないというのが現状である。
Amazake is a traditional Japanese sweet drink that is made by mixing rice bran and cooked rice, heating them, saccharifying them, diluting them with hot water or dissolving sake lees, and adding salt and ginger as needed. This amazake contains various components such as water-soluble vitamins, minerals, amino acids, organic acids, and dietary fiber, and is a food rich in nutrients.
However, in order to saccharify Amazake by mixing rice bran and cooked rice, it must be maintained at a predetermined temperature for a long time, and management and experience are required. Moreover, because there are not many rice bran sales offices, it is not possible to make amazake easily, and even when dissolving sake lees to make amazake, a large amount of amazake can be produced at once, making a small amount of amazake easily. The current situation is that it is not possible.

そこで、甘酒製品として、適度の濃度とした甘酒を缶詰などにした密封容器入りの甘酒が販売されている。甘酒を長期保存する場合は通常レトルト殺菌されるが、甘酒はpHが高いため、室温で長期保存しうるだけの十分な高温殺菌を単に行うと変色や変質が起こる。そのため、酸味料を添加し、pHを下げて殺菌条件を弱めること(pH調整)が行われているが、食品衛生法で規定する条件にすると、酸味が強すぎて、甘酒本来のコクや風味が減殺されるおそれがあった。
また、レトルト甘酒の販売にあたり、ホットベンダーや缶ウオーマーなどで長時間加温しておくと、甘酒中に含まれる還元性の糖類がアミノカルボニル反応を起こして褐変したり、風味が損なわれることがあった。特に、甘酒は色が白いために変色が目立ち、少しの変色でも商品価値を失ってしまうおそれがある。
Therefore, as a sweet sake product, a sweet sake in a sealed container in which sweet sake with an appropriate concentration is canned is sold. When amazake is stored for a long period of time, it is usually sterilized by retort. However, since amazake has a high pH, discoloration or alteration occurs if it is simply subjected to high-temperature sterilization sufficient for long-term storage at room temperature. For this reason, acidulants are added to lower the sterilization conditions by lowering the pH (pH adjustment). However, if the conditions specified by the Food Sanitation Law are used, the acidity is too strong, and the original richness and flavor of amazake Could be killed.
In addition, when selling retort amazake, if it is warmed for a long time with a hot bender or canned warmer, the reducing sugars contained in the amazake may undergo an aminocarbonyl reaction and turn brown or the flavor may be impaired. there were. In particular, amazake has a white color, so discoloration is conspicuous, and even a slight discoloration may lose commercial value.

甘酒の変色防止方法としては、例えば、特許文献1及び2が提案されている。
特許文献1には、米麹及び非還元性の甘味成分を含み、エチルアルコール含量が1%以下、グルコース、マルトース及びイソマルトースからなる還元性糖類の含量が10%以下であり、pHが3.5〜5.0である密封容器入り甘酒飲料が開示されている。特許文献1によれば、甘酒の変色防止をある程度改善できるが、さらに効果的な褐変防止が望まれている。
特許文献2には、甘酒の糖化工程中でアスコルビン酸及び/又はエリソルビン酸を0.01〜0.1重量%添加して混合するレトルト甘酒の製造方法が開示されている。しかしながら、特許文献2の方法では、満足すべき褐変防止効果が得られなかった。
For example, Patent Documents 1 and 2 have been proposed as methods for preventing amazake discoloration.
Patent Document 1 contains rice bran and a non-reducing sweetening ingredient, has an ethyl alcohol content of 1% or less, a content of reducing sugars composed of glucose, maltose and isomaltose of 10% or less, and a pH of 3. Amazake beverages in sealed containers that are 5 to 5.0 are disclosed. According to Patent Document 1, amazake discoloration prevention can be improved to some extent, but more effective browning prevention is desired.
Patent Document 2 discloses a method for producing a retort amazake in which 0.01 to 0.1% by weight of ascorbic acid and / or erythorbic acid is added and mixed during the saccharification process of amazake. However, in the method of Patent Document 2, a satisfactory browning prevention effect was not obtained.

一方、フィチン酸などのキレート剤と非イオン界面活性剤からなる食品保存料(特許文献3参照)、フィチン酸類、クエン酸類及びリン酸類などの2種以上からなる食品の品質保持剤(特許文献4参照)が知られている。しかしながら、特許文献3及び4の食品の保存料及び品質保持剤は、水産加工品、魚肉・畜肉加工品、野菜加工品などの変質防止を目的とするものであり、甘酒についての検討はなされていない。   On the other hand, a food preservative comprising a chelating agent such as phytic acid and a nonionic surfactant (see Patent Document 3), a food quality preservation agent comprising two or more of phytic acid, citric acid, and phosphoric acid (Patent Document 4) See). However, the food preservatives and quality-preserving agents of Patent Documents 3 and 4 are intended to prevent alteration of processed fishery products, processed fish / livestock meat products, processed vegetable products, etc., and studies on amazake have been made. Absent.
