Assaying the performance of anion plasma technology applied for food preservation (Case study: Mustard green and orange)

Abstract

Recently, anion plasma technology has gained public interest for the improvement of human health and biological processing. This study aimed to obtain the effect of preserving food using anion plasma technology on food quality of mustard green and orange. The anion plasma was generated through negative ion generator 12VDC that emitted -2 – 6 kVDC and placed in front of an axial fan in a closed chamber. Furthermore, it was used in treating the samples at different processing times ranging from 5 – 15 hours. The investigation was conducted for seven days with non-isothermal storage at room temperature (25 – 33°C) and the examined food quality included pH-value, weight loss, organoleptic quality, microbial contaminant, and nutritional content. The result showed that there was no significant c
