<p>PROBLEM TO BE SOLVED: To easily obtainγ-aminobutyric acid useful as a health food ingredient, being a non-protein constituent amino acid and having cerebral metabolism promoting activity and antihypertensive activity, by producing the aimedγ- aminobutyric acid through the decarboxylase activity of lactobacillus in fermented dairy products. SOLUTION: This compound i,e.,γ-aminobutyric acid, useful as an ingredient in health food highly rich inγ-aminobutyric acid, being a non-protein constituent amino acid widely occurring in animals and plants, because of having cerebral metabolism promoting activity and antihypertensive activity as the major inhibitory neurotransmitter, is easily obtained by adding milk to a fermented diary product, such as yogurt, leaving the mixture to stand overnight at 30 deg.C, and after addition of sodium glutamate, again, leaving the 2nd mixture to stand overnight at room temperature, thereby, producing the objectiveγ-aminogutylic acid through the glutamic decarboxylase activity of lactobacillus in the fermented diary product and through the action of vitamin B6 phosphoric compound in the milk.</p> |
