Of ethyl β-benzoylacrylate and its derivatives, ethyl α-(2-hydroxyethylamino)-β-benzoyl-propionate hydrochloride (EBPE) is a white powder, easily soluble in water and has low toxicity. The effects of various factors on antimicrobial activities of EBPE against Hiochi-bacteria in Sake were studied and sensory test of Sake containing it was carried out. Results are as follows : .1. The minimum concentration for complete growth inhibition against various Hiochi-bacteria in diluted Sake (alc. 13%) or peptone-Sake (diluted Sake, 1% polypeptone added) was 7.8-15.6 ppm and its antimicrobial activity was about thirty times as high as salicylic acid (SA).2. The effect of EBPE against Hiochi-bacteria was not influenced by pH of Sake and kind of Sake, and increased correspondingly to the increment of ethanol concentration in Sake.3. The antimicrobial activity of EBPE was not affected by addition of a sedimentation agent in Sake, but was extremely decreased by addition of active carbon corresponding to the amount added.4. Antimicrobial action of EBPE against Hiochi-bacteria in Sake was as bacteriostatic as salicycic acid.5. From the results of the sensory test, no different taste from the ordinary Sake was found in Sake containing 10 to 15 ppm of EBPE by which putrefaction of Sake was prevented.
