Table 2. Effects of pilot-scale plasma-activated water (PAW) treatment on the pH of mung bean sprouts during storage at 4°C for 14 days

Storage time (day)	pH
	Distilled water-treated	NaOCl-treated	PAW-treated
0	6.00±0.14Ab	5.95±0.05Aa	5.90±0.10Ab
3	6.10±0.05Aab	5.96±0.06Ba	6.00±0.05Bab
7	6.17±0.02Aab	5.98±0.09Ba	6.04±0.09Ba
10	6.17±0.02Aa	5.99±0.08Aa	6.04±0.08Ba
14	6.16±0.01Aab	6.01±0.13Ba	6.12±0.02ABa

Plasma discharge time: 30 min, treatment time: 30 min.
Means followed by the same lowercase letter within a column are not significantly different between the same treatment, while those followed by the same uppercase letter within a row are not significantly different between the treatments stored at each storage day (p>0.05).
