PURPOSE:To obtain 'MISO' (paste made of fermented soybean, used for preparing soup), soy sauce and fermented soybeans more tasty than conventional 'MISO', etc., in a short period, by subjecting raw material soybeans dipped in dilute hydrochloric acid to aging and thermal processing by direct electric conductive action, steaming or boiling the resultant soybeans and further fermenting the steamed or boiled soybeans. CONSTITUTION:Raw material soybeans (A) are initially washed with dilute hydrochloric acid (B) and then dipped. The above-mentioned raw material soybeans (A), together with the dilute hydrochloric acid (B), are contained in an insulating heat-resistant container 101 and a current is passed across a pair of electrodes 103 and 103 to carry out aging and thermal processing of the above-mentioned raw material soybeans (A) using the afore-mentioned dilute hydrochloric acid (B) as an electrically conductive medium. Furthermore, the raw material soybeans (A) are steamed in a pressure steaming vessel, etc., or boiled in a pressure cooker, etc., then transferred to a fermentation room and fermented to afford and aimed 'MISO', soy sauce and fermented soybeans. |
