Nitrite content in powders from plasma-activated egg whites

These are source data collected to determine the effects of three quantitative independent variables—plasma treatment time, the distance of the plasma source from the surface of egg whites, and drying temperature—on the nitrite concentration (mg·kg⁻¹) in powdered plasma-treated egg whites sourced from both hens and ostriches. The experimental ranges for these variables were as follows: plasma treatment time (20-180 minutes), plasma source distance (10-30 cm), and drying temperature (40-50 °C). The analysis of nitrite content in all samples was conducted according to the method of Lee et al. (2018) with some modifications. A design comprising 20 experimental runs was generated using Design Expert (version 11) software (Stat-Ease, Inc., USA).
