Comparative Evaluation of Ultrasonic, High Pressure, and Pulsed Electric Field Processing on the Extraction and Storage Stability of Betalains From Red Beet By-Products. [PDF]

J Food Sci
ABSTRACT This study explores the potential of red beet peel (RBP) and red beet stalk (RBS), often underutilized by‐products, as rich sources of natural pigments and bioactive compounds. Three non‐thermal green extraction methods, namely, high‐pressure processing, ultrasound, and pulsed electric field treatment, were evaluated for their efficiency in ...

The Decisive Step in Betaxanthin Biosynthesis Is a Spontaneous Reaction1 [PDF]

Plant Physiology, 1999
Abstract Experiments were performed to confirm that the aldimine bond formation is a spontaneous reaction, because attempts to find an enzyme catalyzing the last decisive step in betaxanthin biosynthesis, the aldimine formation, failed. Feeding different amino acids to betalain-forming hairy root cultures of yellow beet (Beta vulgaris L.
