Abstract

A method for rapid low-salted pickling of aquatic products is disclosed, which includes preliminary processing of raw materials, bacteria-reducing treatment of plasma activation gas, marinade adding and plasma treatment, cyclic bacteria-reducing treatment with the plasma activation gas and vacuum pickling. The marinade adding and plasma treatment include respectively injecting the marinade and plasma working gas into a tumbler, with a flow rate of ionic working gas injected into the tumbler of 1.5-2 L/min and a flow rate of a pickling solution of 0.5-0.8 L/min: and at the same time, starting a plasma power supply, and performing low-temperature plasma treatment on the aquatic products to be pickled, with a plasma treatment voltage of 12000-15000 V, a current of 60-80 mA, a frequency of 8-10 kHz, which is a second bacteria-reducing treatment, with plasma treatment time of 15-20 min.
