Other claims from this paper (10)
- Intervention effect Melatonin delayed loss of water, soluble solids and Vitamin C in fresh-cut lotus roots.
- Intervention effect Melatonin decreased microorganism growth on lotus roots.
- Intervention effect Melatonin enhanced total phenolic content.
- Intervention effect Melatonin improved total antioxidant capacity.
- Intervention effect Melatonin lowered reactive oxygen species contents.
- Intervention effect Melatonin enhanced phenylalanine ammonialyase, polyphenol oxidase and superoxide dismutase activities.
- Association NnSOD, NnCAT and some NnPOD transcripts followed a pattern similar to enzyme activity.
- Mechanism The authors infer that melatonin enhanced antioxidant and AsA-GSH systems through ROS-related genes, improving browning resistance and quality.
- Intervention effect Melatonin suppressed spoilage organisms in the lotus microbiome.
- Observation Metabolites from four metabolic pathways were implicated in the browning process.
