Abstract

Few reports are on the application of cold plasma (CP) for mold and mycotoxin control in grain. The aim of this study was to evaluate the viability of CP for mycotoxin and mold control in rice grain. Rice grains artificially contaminated with molds or mycotoxins were subjected to CP treatment. The microbial activities of Aspergillus niger, Rhizopus oryzae, Penicillium verrucosum and Fusarium graminearum were significantly inhibited by CP treatment. The maximal reduction of DON and OTA were 61.25 % and 55.64 %, respectively. The electrical conductivity and malondialdehyde content in rice grain increased at most by 30.14 % and 103.27 %, respectively. The seed germination reduced significantly when treatment time reached 8 min. The major nutrients of rice grain were not affected except for prolamine, which was generally consistent with the results of electron microscopy and Fourier-transform infrared analysis. Cold plasma is a promising method for mold and mycotoxin control in rice grain.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Cold plasma significantly inhibited the microbial activity of Aspergillus niger, Rhizopus oryzae, Penicillium verrucosum, and Fusarium graminearum on rice grains artificially contaminated with mold or mycotoxins.

    “For example, a recent study showed that when rice grains artificially contaminated with mold or mycotoxins were subjected to cold plasma, microbial activity of Aspergillus niger, Rhizopus oryzae, Penicillium verrucosum and Fusarium graminearum was significantly inhibited36.”

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.
