Description

酸性液状食品及びその製造方法Acidic liquid foods and their manufacturing methods
 本発明は、酸性液状食品に関し、詳細には、少なくとも、水、加熱糊化型澱粉、及びガム類を含む酸性液状食品に関する。また、本発明は、少なくとも、水、加熱糊化型澱粉、及びガム類を含む酸性液状食品の製造方法に関する。 The present invention relates to an acidic liquid food, and more particularly to an acidic liquid food containing at least water, heat-gelatinized starch, and gums. The present invention also relates to a method for producing an acidic liquid food containing at least water, heat-gelatinized starch, and gums.
 従来、コンビニエンスストアやスーパーマーケットにて販売されているパンや弁当、おにぎり等は調味のため、ソース等の液状食品が使用されている。これらの液状食品は、それ自体の持つ本来の風味が良いことが求められるだけでなく、使用する目的によっては機能性が求められる。この機能性のなかでも特に求められる機能性として、パンや弁当、おにぎり等に調味した後、パンや米飯にすぐに染み込んでしまわないということが挙げられる。 Conventionally, liquid foods such as sauces are used for seasoning such as bread, bento boxes, and rice balls sold at convenience stores and supermarkets. Not only are these liquid foods required to have a good original flavor, but also functionality is required depending on the purpose of use. Among these functions, the one that is particularly required is that after seasoning bread, bento boxes, rice balls, etc., it does not immediately soak into bread or cooked rice.
 例えば、パンや生地などから液だれしにくく、食材等への染み込みがなく、焼成時の耐熱保形性及び色の保持性に優れ、懸濁安定性、容器から取り出す際の流動性に優れた液状食品として、耐酸安定性に優れるセルロース複合体と、果実及び/又は野菜を含有する液状食品が提案されている(特許文献1参照)。 For example, it does not easily drip from bread or dough, does not soak into foodstuffs, has excellent heat-resistant shape retention and color retention during baking, has excellent suspension stability, and has excellent fluidity when taken out of a container. As a liquid food, a liquid food containing a cellulose complex having excellent acid resistance stability and fruits and / or vegetables has been proposed (see Patent Document 1).

 本発明者らは、酸性液状食品に多量の澱粉を含有させて粘性を上げ、パンや米飯に染み込み難くすることを試みたが、澱粉として冷水膨潤型澱粉を用いた場合、酸性液状食品の製造工程の初期段階で増粘してしまい、原料の撹拌・混合を容易に行うことができず、製造適性が劣るという課題を知見した。そこで、酸性液状食品に澱粉として冷水膨潤型澱粉の代わりに加熱糊化澱粉を用いたところ、今度は長期保存後で粘性を維持できず、さらには離水し易いという新たな課題を知見した。また、加熱糊化澱粉は冷水膨潤型澱粉のように製造工程の初期段階で増粘しないため、澱粉自体が沈殿してしまい、製造適性が劣るという課題も知見した。 The present inventors have attempted to add a large amount of starch to an acidic liquid food to increase its viscosity so that it does not easily soak into bread or rice. However, when cold water-swelling starch is used as the starch, an acidic liquid food is produced. It was found that the starch was thickened at the initial stage of the process, the raw materials could not be easily stirred and mixed, and the production suitability was inferior. Therefore, when heated gelatinized starch was used as the starch in the acidic liquid food instead of the cold water swelling type starch, it was found that the viscosity could not be maintained after long-term storage and the water could be easily separated. It was also found that the heat-gelatinized starch does not thicken at the initial stage of the production process unlike the cold water swelling type starch, so that the starch itself precipitates and the production suitability is inferior.
 本発明は、上記の課題に鑑みてなされたものであり、製造適性に優れ、長期保存後の離水及び粘度低下を防止し、かつパンや米飯に染み込み難い酸性液状食品を提供することにある。 The present invention has been made in view of the above problems, and an object of the present invention is to provide an acidic liquid food product which is excellent in manufacturing suitability, prevents water separation and viscosity decrease after long-term storage, and does not easily soak into bread or cooked rice.
 本発明者等は、上記課題を解決するために鋭意検討した結果、驚くべきことに、加熱糊化型澱粉及び特定のガム類を一定の割合で含有させ、かつ、粘度及びブリックスを調節することによって、上記課題が解決できることを知見した。本発明者等は、当該知見に基づいて、本発明を完成するに至った。 As a result of diligent studies to solve the above problems, the present inventors surprisingly contain heat-gelatinized starch and specific gums in a certain ratio, and adjust the viscosity and brix. It was found that the above problems can be solved. The present inventors have completed the present invention based on the findings.

 澱粉には、加熱糊化型澱粉と冷水膨潤型澱粉があり、本発明では加熱糊化型澱粉を用いる。加熱糊化型澱粉は、水を加えて高温で、より具体的には、例えば70℃程度以上で加熱することで糊化し、吸水して膨潤すると同時に粘性を呈する澱粉である。一方、冷水膨潤型澱粉は、糊化した状態の性質がそのまま維持された澱粉であり、加熱を必要とせず常温(20℃)の水で膨潤し粘性を呈する澱粉である。本発明においては、澱粉として加熱糊化型澱粉を用いると、酸性液状食品の製造工程の初期段階では高温がかからずに増粘しないため、原料の撹拌・混合を容易に行うことができる。その後、混合物の加熱処理の際の熱により増粘し、適度な粘性の酸性液状食品を得ることができる。一方、澱粉として冷水膨潤型澱粉を用いると、酸性液状食品の製造工程の初期段階で増粘してしまい、原料の撹拌・混合を容易に行うことができず、製造適性が劣るものとなる。
(Heat gelatinized starch)
There are two types of starch, heat gelatinized starch and cold water swelling starch, and in the present invention, heat gelatinized starch is used. The heat-gelatinized starch is a starch that gelatinizes by adding water and heating at a high temperature, for example, about 70 ° C. or higher, absorbs water, swells, and at the same time exhibits viscosity. On the other hand, the cold water swelling type starch is a starch that maintains the properties of the gelatinized state as it is, and is a starch that swells with water at room temperature (20 ° C.) and exhibits viscosity without requiring heating. In the present invention, when the heat-gelatinized starch is used as the starch, the raw materials can be easily stirred and mixed because the starch does not become thickened at the initial stage of the manufacturing process of the acidic liquid food. After that, the mixture is thickened by the heat of the heat treatment, and an acidic liquid food having an appropriate viscosity can be obtained. On the other hand, when cold water-swelling starch is used as the starch, the viscosity is increased at the initial stage of the manufacturing process of the acidic liquid food, and the raw materials cannot be easily stirred and mixed, resulting in poor manufacturing suitability.
