Abstract:Based on the synergistic effect of ultrasonic technology and low-temperature plasma-activated water,the degradation of residual antibiotics in Auriculɑriɑ ɑuriculɑ was performed to provide a technical method for pollutant control in A.ɑuriculɑ production.The results showed that when A.ɑuriculɑ with an antibiotic concentration of 0.5 mg/kg was immersed in low-temperature plasma activated water and treated for 45 min under the conditions of ultrasonic power of 480 W,temperature of 30 ℃,frequency of 25 kHz,the degradation rates of ciprofloxacin and enrofloxacin in A. ɑuriculɑ were 51.92% and 55.47%,respectively. The antibiotic degradation effect after the response surface optimization test was not significantly different from the predicted value.After treatment,the contents of total sugar,crude protein and crude fat in A. ɑuriculɑ decreased by 5.24%,1.24% and 0.12%,respectively,while crude fiber and ash had no obvious change.All of them can meet the requirements of physicochemical indexes of A.ɑuriculɑ in national standards.Therefore,ultrasonic-assisted lowtemperature plasma-activated water has a good degradation effect on the antibiotics in A.ɑuriculɑ.
