Abstract

<abstract abstract-type="main"> <title>Abstract</title> <sec id="jfq12056-sec-0001" sec-type="section"> <p>The effects of chitosan (CTS, 10 g/L) coating, alone or in combination with nano‐chitosan (N‐CTS, 1.5 g/L), on browning and lignification of fresh‐cut <italic>Z</italic><italic>izania latifolia</italic> were investigated for 12 days at 1C. Results showed that the application of CTS and CTS/N‐CTS coating significantly retarded the increase in total color difference (Δ<italic>E</italic>) and lignin content and inhibited the activity of phenylalanine ammonia‐lyase and peroxidase while improving that of superoxide dismutase, catalase and ascorbate peroxidase, thus reducing malondialdehyde accumulation. The present findings indicate that CTS and CTS/N‐CTS coatings could retard browning and lignification of fresh‐cut <italic>Z</italic><italic>. latifolia</italic> during storage at 1C. As the CTS/N‐CTS coating gives the better effect, it is suggested that the CTS/N‐CTS coating can be used for control of browning and lignification of fresh‐cut <italic>Z</italic><italic>. latifolia</italic>.</p> </sec> <sec id="jfq12056-sec-0002" sec-type="section"> <title>Practical Applications</title> <p>The presented study showed that CTS/N‐CTS coating could inhibit browning‐ and lignification‐related enzyme activity, induce higher antioxidant enzyme activity and reduce lipid peroxidation of fresh‐cut <italic>Z</italic><italic>. latifolia</italic> during storage at 1C. These results suggested that the CTS/N‐CTS coating could effectively inhibit browning and lignification in fresh‐cut <italic>Z</italic><italic>. latifolia</italic>, which provides a theoretical basis for commercial application.</p> </sec> </abstract>
