Abstract:
he effect of ultra high pressure treatment (100~600 MPa)and treatment time(10~30 min) on peroxidase and polyphenol oxidase activity and contents of Vc, chlorophyll and soluble protein of Juglans regia L flowers were studied. Results showed that residual enzyme activity of POD and OPP were decreased obviously under 500 MPa for 15 min , preventing its browning effectively during storage and maximum while retaining the main nutrition, Vc and color. This research provided the basis for the development and utilization of Juglans regia L. flowers.
