Abstract:

Citrus is the largest category of fruit in China, which is widely planted and has many cultivars for fresh fruit market. To extend shelf life, promote intensive processing, improve enterprise’s benefit, current research progresses related to fruit storage and processing have been reviewed. At first, new preservation technologies applied in Citrus fruits’ storage were summarized. Subsequently, innovation technologies for processing products and by-products utilization were discussed. Finally, functional components in Citrus with potential application in pharmaceutical industry were also reviewed. Therefore, depending on different cultivars in production areas, fruit sorting system after post-harvest are recommended for orange and lemon varieties. Meanwhile, the non-thermal processing technology and enzymatic digestion for de-peeling is utilized for tradition processing products, such as sweet orange and tangerine. Functional components in Citrus will be extracted and prepared to medicinal and edible food. In conclusion, new technology for storage and processing are used in Citrus to extendindustry chain, which significantly boost industry development in future.
