First claim
Opening claim text (preview).
1 . A growth inhibitor for microorganisms comprising isoxanthohumol as an active ingredient. 2 . The growth inhibitor for microorganisms according to claim 1 , which is for beverage use. 3 . The growth inhibitor for microorganisms according to claim 1 , wherein the microorganisms comprise at least one bacterium selected from the group consisting of a bacterium of the genus Alicyclobacillus , a bacterium of the genus Bacillus , a bacterium of the genus Clostridium , and a bacterium of the genus Staphylococcus. 4 . The growth inhibitor for microorganisms according to claim 1 , wherein the microorganisms comprise at least one species selected from the group consisting of Alicyclobacillus acidoterrestris, Bacillus cereus, Clostridium perfringens, Clostridium difficile , and Staphylococcus aureus. 5 . A method of preventing contamination of a beverage by microorganisms, comprising adding isoxanthohumol to a concentration of 25 mass ppm or more. 6 . The method of preventing contamination by microorganisms according to claim 5 , wherein isoxanthohumol is added to a concentration of 50 mass ppm or more. 7 . The method of preventing contamination by microorganisms according to claim 5 , further comprising adjusting a pH of the beverage to 4.6 or lower. 8 . The method of preventing contamination by microorganisms according to claim 5 , wherein the microorganisms comprise at least one bacterium selected from the group consisting of a bacterium of the genus Alicyclobacillus , a bacterium of the genus Bacillus , a bacterium of the genus Clostridium , and a bacterium of the genus Staphylococcus. 9 . The method of preventing contamination by microorganisms according to claim 5 , wherein the microorganisms comprise at least one species selected from the group consisting of Alicyclobacillus acidoterrestris, Bacillus cereus, Clostridium perfringens, Clostridium difficile , and Staphylococcus aureus. 10 . A beverage comprising more than 50 mass ppm and 180 mass ppm or less of isoxanthohumol and having a pH of 4.6 or lower. 11 . The beverage according to claim 10 , which comprises 60 mass ppm or more of isoxanthohumol. 12 . The beverage according to claim 10 , which is an alcohol beverage, non-alcoholic beer taste beverage, carbonated beverage, functional beverage, or fruit and/or vegetable-based beverage. 13 . The beverage according to claim 10 , which is a non-alcoholic beer taste beverage, functional beverage, carbonated beverage, or fruit and/or vegetable-based beverage.
