Toona sinensis, a woody vegetable, is highly valued for its nutritional and medicinal properties. However, with the continuous improvement of people's living standards and the general concern about food safety, they want to consume Toona sinensis safely and for a prolonged period. Therefore, new requirements have been put forward for the preservation of Toona sinensis. In this paper, we summarize the research results of Toona sinensis from the perspectives of post-harvest physiological changes and preservation technology, analyze the changes of physiology, biochemistry, and quality of Toona sinensis after harvest, and analyze the effects of different post-harvest preservation technologies on the quality of Toona sinensis, as well as look forward to the future preservation of Toona sinensis and the direction of research. The aim is to extend the storage period of Toona sinensis, improve its economic value, provide a theoretical reference for the study of Toona sinensis processing and preservation technology, and also provide a reference for the preservation of woody vegetables.
