Enzymatic browning experiment: What happens when an already brown potato is treated with ascorbic acid?
Enzymatic browning experiment: What happens when an already brown potato is treated with ascorbic acid?
Homework Answers
Solution:
Brown color of potato occurs due to poly phenol oxidase activity and It is best active at pH in between 5 to 7 when we add the ascorbic acid it lower the pH and activity of poly phenol oxidase stop, consequence of this more browning of potato stop.
