Elimination of Aspergillus flavus from Pistachio Nuts with Dielectric Barrier Discharge (DBD) Cold Plasma and Its Impacts on Biochemical Indices

Table 2

Effect of cold plasma (0–180 sec) on aflatoxin B₁ concentration (ppb) in pure toxin and contaminated pistachio nut powder.

Aflatoxin B1 concentration (ppb)	Time of plasma treatments (sec)
	0	60	120	180
Pure toxin	710.38^a ± 0.93	458.89^b ± 0.88	277.27^c ± 1.06	251.32^d ± 0.88
Pistachio nut powder	383.19^a ± 0.38	259.39^b ± 1.11	211.64^c ± 1.70	182.32^d ± 1.78
