| Zusammenfassung: | The plasma energy is a collection of free particles with positive and negative charges and has demonstrated to be a good prospect for food preservation. The aim of this study was to evaluate the effect of plasma energy on the antioxidant activity, total polyphenol content and yeasts and molds counts in chamomile and cinnamon powder samples treated at 650, 750 and 850 volts for 0, 1, 3 ,5 7 and10 min. Total counts of yeasts and molds in chamomile and cinamon powder samples were determined before and after each treatment with plasma energy. The enumeration was conducted on potatoe dextrose agar suplemented with 0.6% Bengal rose and 2% ampicillin. The antioxidant activity and total polyphenol content were also analyzed. The results showed that plasma exposure on chamomile and cinnamon powder at 850V for 10 minutes significantly reduced (p |
