Formation of Green-Blue Compounds in Brassica rapa Root by High Pressure Processing and Subsequent Storage

Abstract

The effect of high pressure treatment on biochemical changes during storage was investigated using Brassica rapa root. High pressure treated samples with 400 and 600 MPa formed unique green-blue color during 7-d storage at 4 °C. The mechanism of green-blue compound formation would be based on biochemical pathway for a unique green-blue pigment synthesis, containing O₂-dependent steps and possibly enzymatic reactions.
