Abstract:
Taking ginger as test materials,the effect of O2/CO2 controlled atmospheres on active oxygen metabolism and storage quality of ginger were studied by using five different treatments of 100%O2,90%O2+10%CO2, 80%O2+20%CO2,70%O2+30%CO2,and natural air CK were set as control,and the oxygen metabolism and storage quality of ginger were measured during storage at 20℃.The results showed that proper O2/CO2 controlled atmosphere especially 100%O2 treatment could maintain high activities of superoxide dismutase (SOD) and peroxidase (POD),reduce the contents of O?-2 and H2O2,and enhance ginger’s defense system for reactive oxygen,maintain soluble sugar content and vitamin C content of ginger,extend the shelf life of fresh ginger.The effect of 90%O2+10%CO2 treatment was a little worse than that of 100%O2 treatment,but there was no significant difference between them.70%O2+30%CO2 treatment behaved the worst effect among all treatments.
