Postharvest physiology and storage quality of green asparagus treated by high hydrostatic pressure processing were investigated.Green asparagus were treated at various pressure ranges (20MPa,50MPa,and 100MPa) for 2 minutes,and all the samples were stored at 4℃ and 90% relative humidity for 15 days.During the storage,the changes of respiration rate,malondialdehyde (MDA) content,cell membrane relative permeability,chlorophyll content,firmness,weight loss,and color were determined.The results showed that the samples treated by high hydrostatic pressure exhibited significantly decreased in respiration rate,total chlorophyll content,and maintained higher firmness and better color compared with untreated samples.These results provided a basis for the application of high hydrostatic pressure processing as an approach on postharvest storage of green asparagus.
