Review on the Mechanism and Control Technologies of Greening of Postharvested Potato Tubers
Potato is the world's third largest food crop and is susceptible to greening during post-harvest storage,transportation,and marketing.Although greening is not directly related to solanine,it may cause safety concerns and affect consumers'purchasing desires.The article first made a scientific explanation of the relationship between potato greening and solanine and then elaborated on the physiological and biochemical mechanism of potato greening from the two biological processes of conversion of amyloplasts to chloroplasts and chlorophyll accumulation.In addition,the article analyzed the effects of light conditions,temperature,and variety on the greening process,outlined a variety of methods for detecting greening in potatoes,of which non-destructive testing technology has a broad market prospect,and finally reviewed the prevention and control of greening from three aspects,namely,physical method,chemical method,and cross-breeding.The summary of the article helps to deepen the understanding of potato greening and provides technical guidance for the scientific prevention and control of greening.
