A kinetic study on carrot juice treated by dielectric barrier discharge (DBD) cold plasma during storage
Open accessAbstract
This study aimed to investigate the efficacy of DBD cold plasma (CP) on carrot juice quality maintenance and develop suitable shelf life models based on carotenoid degradation and total mesophilic bacteria (TMB) growth. The physicochemical, microbial, and sensory properties of carrot juice treated with CP (8, 10, and 12 kV for 3 min) and heat (80 °C for 7 min) were evaluated during storage at 4 °C for 21 days. Results showed carrot juice treatment with the lowest voltage (8 kV) better preserved the physicochemical properties (ascorbic acid and total phenol), color changes, microbial growth, and sensory deterioration. The temperature effect on TMB growth was modeled using the Baranyi and Roberts model, followed by the Arrhenius and square root models. The Q10 and activation energy (Ea) values of TMB growth were higher than those for carotenoid degradation, proposing that bacterial growth could be a more reliable marker in the self life prediction of carrot juice treated by DBD cold plasma.

Nitric oxide (NO) generated during CP treatment can enhance the activity of dehydroascorbate reductase, thereby promoting the synthesis of ascorbic acid.
“Previous studies have reported that nitric oxide (NO) generated during CP treatment can enhance the activity of dehydroascorbate reductase, thereby promoting the synthesis of ascorbic acid [46].”

Nasri noted that plasma treatment induced the degradation of aromatic rings in carrot juice, releasing more phenolic compounds and thereby augmenting the TPC.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
