PROBLEM TO BE SOLVED: To obtain a component having a useful physiological activity from barley, and to use it as a bioactive agent using the same, and to provide a functional food material or a functional food using the same. To provide. SOLUTION: By extracting the barleys which have been subjected to explosion treatment with an aqueous solvent, it is found that an extract mainly from the hull fraction has a useful bioactive activity, The present invention has been made. The active ingredient of the physiologically active barley extract of the present invention is a water-soluble substance, having a molecular weight of 500,000 or less, a main component of which is 100,000 or less, a protein content of 3 to 30%, water-soluble ferulic acid and p-coumaric acid. Rich, immune enhancing, blood pressure lowering, blood flow improving, angiotensin I It has a physiologically active action such as converting enzyme inhibitory action and antibacterial action. A bioactive agent, a functional food material and a functional food are produced using the bioactive barley extract of the present invention. |
