Abstract

<abstract abstract-type="main"> <title>Abstract</title> <sec id="jfpp12078-sec-0001" sec-type="section"> <p>Effect of nano‐packing combined controlled atmosphere (CA + NP) on postharvest physiology and biochemistry of Gynura (<italic>Gynura bicolor</italic> D.C) was investigated during 20‐day storage at 0C. The results showed that the CA + NP had a quite beneficial effect on physicochemical and sensory quality of Gynura compared with nano‐packing (NP) or normal polyethylene packaging with a controlled atmosphere (CA). After 20‐day storage, decay index was increased to 8.97% for CA + NP, 9.23% for NP and 9.64% for CA, respectively. Relative leakage rate, O<sub>2</sub><sup>●‐</sup> production and MDA content of CA + NP were significantly inhibited. Meanwhile, CA + NP effectively reduced the activities of PPO, and enhanced the activities of the enzymes POD, CAT and SOD. These results indicated that CA + NP could provide a promising alternative for extending storage life and improving postharvest quality of Gynura.</p> </sec> <sec id="jfpp12078-sec-0002" sec-type="section"> <title>Practical Applications</title> <p>Gynura, a Chinese herbal medicine, has also been used as food substances throughout Asia for centuries. Since the main pharmacological composition on it has not been determined, the fresh Gynura demand increases gradually. However, postharvest decay of Gynura is the main limitation to market acceptance, this study has given an experimental evidence that CA + NP could provide a promising alternative for extending storage life and improving postharvest quality of Gynura. Furthermore, these nano‐packing materials have the advantages of simple processing and industrial feasibility in contrast with other storages, some of which are time‐consuming and costly.</p> </sec> </abstract>
