Komal D. Barad, Vijay R. Parmar & Rajesh Raviya

ABSTRACT:

The A. auricula is used as both an edible and medicinal mushroom worldwide. It is the third most cultivated mushroom and is widely grown in East Asian countries. This paper highlights the polyphenol oxidase (PPO) activity in A. auricula. The PPO activity was determined using catechol extract at various concentrations. It was observed that as the concentration increased, the PPO activity also increased. The presence of the PPO enzyme in this mushroom suggests that A. auricula could be very useful in the food industry as a future resource.
