PROBLEM TO BE SOLVED: To provide a bean sprout growing system by which the concentration of ethylene gas is managed in a high accuracy at the concentration of about 0.1-5 ppm even when using ethylene derived from ethanol (fermented ethanol) obtained by fermentation, so as to control the growth of bean sprouts. SOLUTION: The bean sprout growing system includes: an ethylene gas supplying part where the ethylene derived from ethanol obtained by fermentation is stored in a pressurized condition; a bean sprout growing chamber where the bean sprouts are grown; and a control part where the concentration of the ethylene in the bean sprout growing chamber is measured using a gas chromatograph, and the ethylene stored in the ethylene gas supply part is supplied to the bean sprout growing chamber from the ethylene gas supplying part in accordance with a preset concentration through utilizing gas pressure difference between the gas pressure in the ethylene gas supplying part and that in the bean sprout growing chamber so as to control the ethylene concentration in the bean sprout growing chamber in a range of the preset concentration. The bean sprout grown by the system is provided. COPYRIGHT: (C)2010,JPO&INPIT
