Pulsed light treatment affects postharvest quality and regulatory mechanisms of sweet corn
Pulsed light (PL) is a novel non thermal physical sterilization technology that utilizes intense pulsed light radiation with instantaneous peak energy to sanitize products. We have investigated the effect of PL on gene expression and metabolites of sweet corn maintained at 20 °C for 6 d after treatment. PL treatment resulted in the downregulation of PG, PAL, CCR and C4H, genes associated with kernel firmness, and the upregulation of POD, SOD, HSP, PR-1, PR-5, genes associated antioxidant capacity and disease resistance. PL treatment also suppressed the expression of genes related to ethylene biosynthesis and signaling. Metabolomic analysis showed that PL treatments increased the contents of lipids, flavonoids, amino acids and their derivatives, lignans, coumarins, organic acids and other metabolites, especially specific compounds such as phenolic acids, flavonoids. This study elucidated the physiological and molecular level regulation mechanism of PL treatment on the postharvest quality.
期刊介绍：
LWT - Food Science and Technology is an international journal that publishes innovative papers in the fields of food chemistry, biochemistry, microbiology, technology and nutrition. The work described should be innovative either in the approach or in the methods used. The significance of the results either for the science community or for the food industry must also be specified. Contributions written in English are welcomed in the form of review articles, short reviews, research papers, and research notes. Papers featuring animal trials and cell cultures are outside the scope of the journal and will not be considered for publication.
