Description

The present invention relates to a beverage containing ferulic acid, rice flour, and one or more selected from water-soluble dietary fiber, vitamin B and vitamin C.

Ferulic acid (4-hydroxy-3-methoxycinnamic acid) is a kind of polyphenol, and has a strong antioxidant effect like other polyphenols, and has an effect of improving hypertension, an effect of improving endurance and an anti-fatigue effect, and an ethanolic hepatitis. It is known to have a healing effect and a symptom improving effect in patients with Alzheimer's disease.

From the above, the demand for ferulic acid as a material for health foods is increasing, and Patent Document 1 describes diseases such as hypertension, which are mainly related to the onset and progression of lifestyle-related diseases and aging. , A preventive food for diseases to which ferulic acid is added is described.

On the other hand, ferulic acid is known to exhibit unpleasant tastes such as bitterness and astringency peculiar to polyphenols. Patent Document 2 describes that the unpleasant taste of a functional material is masked by adding dextrin having certain characteristics to a functional material such as ferulic acid.

However, it cannot be said that the technique for masking the unpleasant taste of ferulic acid has been sufficiently developed. Although Patent Document 2 describes that the unpleasant taste of a functional material is masked by adding dextrin having certain characteristics, it has been confirmed that the taste of foods containing ferulic acid is improved. not. Further, Patent Document 2 does not describe or suggest improvement in the texture and aftertaste of foods containing ferulic acid.

On the other hand, as a form of health food, beverages that can be easily ingested have been attracting attention in recent years. However, beverages are characterized in that they are more likely to feel the unpleasant taste of ferulic acid when ingested, as compared with tablets and capsules. Against this background, there has been a demand for the development of beverages containing ferulic acid as a functional material and further improving the taste of ferulic acid.
