Grey oyster mushroom (Pleurotus sajor-caju) is known to contain antioxidant properties<br />

and bioactive compounds. Objective of this study is to investigate and select the best<br />

cooking method based on physicochemical properties, antioxidant activity and total<br />

phenolic content of grey oyster mushroom. Four cooking methods include deep frying,<br />

boiling, microwaving and grilling will be conducted. Physicochemical properties will be<br />

analyzed based on texture, color and proximate composition. Antioxidant activity will be<br />

determined by using 2, 2- Diphenyl-1- plearylhydrazyl (DPPH) scavenging system and<br />

ferric reducing antioxidant power (FRAP) while total phenolic content will be determined<br />

by using Folin- Ciocalteu method. Proximate composition of grey oyster mushroom will<br />

also be affected by different cooking methods. This study will suggest the best cooking<br />

method that will retain high color, antioxidant activity and polyphenol content of grey<br />

oyster mushroom.<br />
