Effects of packaging material type on the inactivation of total mesophilic aerobic bacteria in steamed rice cakes using in-package atmospheric dielectric barrier discharge cold plasma treatment

Packaging materials	Microbial reduction (log CFU/g)
Low-density polyethylene	0.5 ± 0.1b
Polypropylene	0.7 ± 0.1b
Nylon/low-density polyethylene	1.3 ± 0.2a
Nylon/casted polypropylene	1.3 ± 0.2a

Microbial count of untreated rice cakes: 7.6 ± 0.2 log CFU/g

The results are expressed as the mean ± standard deviation (n = 6). Values followed by different letters in the same column are significantly different (p < 0.05)
