FERMENTATION METHOD AND FERMENTATION APPARATUS

摘要

PROBLEM TO BE SOLVED: To shorten the fermentation time and improve the quality of fermentation product by applying a weak ELF (extremely low frequency) magnetic field to various yeasts. SOLUTION: Water is poured into a vessel 10 and heated to a proper temperature with a heater 12. The heater 12 is removed at the start of the experiment, yeast and water are put into a fermentation test tube 13 and a weak ELF magnetic field is applied to the test tube 13 with a coil 11. The progress of fermentation can be determined by measuring the pH of water in the fermentation test tube 13. The fermentation of yeast can be promoted or suppressed according to the magnetic field intensity and fermentation time by controlling the weak ELF magnetic field.
