Study on the degradation of T-2 toxin in beer by glow discharge plasma
Objective:Exploring the optimal process for the degradation of T-2 toxin in beer by glow discharge plasma(GDP)and its impact on the physicochemical indicators of beer.Methods:Based on single-factor experiments,a response surface optimization experiment with four factors and three levels was conducted using the Box Behnken method to determine the optimal degradation conditions for T-2 toxin in beer.Results:When the discharge voltage was 570 V,the action time was 18 minutes,the discharge current was 99 mA,and initial concentration of T-2 toxin was 8.5 μg/mL.Under the control of these conditions,the degradation efficiency of the T-2 toxin was the highest(89.21％).After GDP treatment,the physical and chemical indicators of beer were tested,and the results showed a significant decrease in beer foam retention(P＜0.05),while other indicators remained unchanged.Conclusion:The optimal degradation conditions of GDP obtained by the response surface optimization model are accurate and reliable,which can be used for the degradation of T-2 toxin in beer.GDP can affectthe brewing ability of beer,but it will not have a significant impact on other indicators.
