Cold atmospheric‐pressure plasma treatment was applied to decontaminate turmeric powder. Cold plasma reduced the aerobic microbial count of turmeric powder by approximately 1.5 log CFU g −1 . Cold plasma exerted both improving and deteriorating effects on essential oil profile of turmeric. Cold plasma enhanced total phenolic and flavonoid contents and diminished antioxidant activity. Cold plasma caused damages on microstructure of turmeric powder.
