Combined Vacuum and Ascorbic Acid Treatment Enhances Texture and Antioxidant Capacity in Fresh-Cut Potatoes: Transcriptomic Elucidation of Glutathione Metabolism Mechanisms.

ABSTRACT: This study investigated the mechanism by which combined vacuum packaging and 0.5% (w/v) ascorbic acid treatment (VP-AsA) preserves fresh-cut potatoes at 4 °C, integrating physiological and transcriptomic analyses. Transcriptome sequencing revealed 2246 differentially expressed genes (DEGs) in the VP-AsA group. Notably, key genes involved in glutathione metabolism and NADPH regeneration-encoding glutathione reductase (GR), glutathione S-transferase (GST), isocitrate dehydrogenase (IDH), glucose-6-phosphate dehydrogenase (G6PDH), and ornithine decarboxylase (ODC)-were significantly up-regulated. This transcriptional reprogramming, which was associated with increased glutathione (GSH) content, provides a molecular basis for the enhanced antioxidant capacity observed in the treat
