Effects of surfactants and polylactic acid plastic on characteristics of food waste acidogenic fermentation
The output of food waste is increasing year by year.Due to the characteristics of high moisture content and easy spoilage,conventional methods are unable to properly dispose of the food waste.Anaerobic fermentation has the advantages of low cost and minimal secondary pollution in treating food waste over other methods.The main product of anaerobic fermentation is volatile fatty acids(VFAs),which have high added value,a wide range of applications,and convenient storage and transportation.This makes anaerobic fermentation a potential method for resource utilization of food waste.However,the presence of exogenous substances,such as surfactants and polylactic acid plastics,in food waste can affect the acid-producing fermentation process in anaerobic fermentation systems.Based on this,this paper introduces the generation,physicochemical properties,and hazards of food waste at first,while also provides an overview of the current methods of treating food waste.On the basis of combing the principle of producing volatile fatty acids by food waste fermentation,this paper presents the research status of using food waste fermentation to produce volatile fatty acids.Finally,the paper discusses the influence of exogenous substances,such as surfactants and polylactic acid plastics,on the acid-producing fermentation of food waste,aiming to provide guidance for the regulation of acid production in food waste fermentation processes.
