Abstract
The changes of chlorophyll content,chroma value(a*,b* and hue angle),activity of the active oxygen scavenging enzymes(SOD,CAT,POD,APX and GR) and content of malondialdehyde(MDA) of postharvest spinach during 2 ℃ and 9 ℃ cold storage were studied.The results showed that,during storage at the two temperatures,the activity of SOD was overall upward trend,during 9 ℃ storage,the content of chlorophyll,hue angle values,activity of CAT,APX and GR of spinach leaf decreased rapidly,and the membrane lipid peroxidation product MDA rapidly accumulated,during 2 ℃ cold storage,the low temperature could delayed the activities decrease of CAT,APX and GR,prevent the rapid increase of membrane lipid peroxidation product MDA,inhibit the decreases of chlorophyll content and hue angle value,and thereby delay the senescence of spinach.
