This study demonstrated CAP effectively inhibited fungal growth and toxin production without adversely affected oil quality.įood-borne microorganisms are one of the biggest concern in food industry. Oil quality indexes of the CAP-treated peanuts were maintained in the range of excellent grades. flavus and aflatoxin concentrations were significantly lower (p < 0.05) on the group treated with 200 W for 5 min than other treatment groups stored for 29 d. Observation under scanning electron microscope revealed the fungal spores were evidently damaged. niger, the treatments at 180 W for 10 min and 200 W for 5 min resulted in undetected population. After treatments at 180 W for 7.5 min and 200 W for 5 min, A. The initial inoculation levels were 6.39 and 5.83 log CFU/g of A. In this study, a novel CAP device with a rotary jet system was used to inactivate the existing A. Cold atmospheric plasma (CAP) has been demonstrated to inactivate fungi effectively. The major safety risk of peanuts is contamination with aflatoxin.
