Dried fruit is a semi dry fruit made by peeling and removing the seeds from fresh fruits, cutting them into slices or blocks, soaking them in sugar, and drying them. Candied fruit is a fruit made by impregnating it with honey, concentrated syrup, etc. Dried fruits include: dried peach, dried plum, dried apple, dried pear, etc; Preserved fruits include Yangmei, preserved plum, Ximei, olives, Yingzi, and so on. China has always had the saying of "preserved fruits from the south and preserved fruits from the north". Wet products are mainly used in the south, while dry products are preferred in the north, commonly known as "preserved fruits from the north and honey from the south".

The development of the candied fruit market has a long history, but due to various reasons, the development speed has been relatively slow. However, in recent years, with the introduction of modern production technology for candied fruit preserves, the market for candied fruit preserves has made a leap forward. Candied fruit preserves are made from fresh fruits and vegetables, rich in various vitamins and fiber, nutritious, and have a sweet taste. They are increasingly sought after and loved by consumers. But behind the deliciousness, consumers still have concerns about the food safety of candied fruits. In order to fundamentally change the quality of candied food, it is necessary to reform the process. Candied food enterprises should abandon the traditional operation method of "boiling and sun drying" in the past, adopt mechanized and industrialized production, focus on improving the hygiene conditions of product production, and achieve the future development goal of low sugar, healthy and hygienic products. In addition, candied food enterprises can also take a long-term view, break away from the idea of using vegetables and fruits as raw materials, search for new raw materials such as flowers, wild fruits, and Chinese medicinal materials, and cultivate new candied products. However, in the current market, the main products are candied fruits and vegetables. These occupy a major position in people's lives. The reform of production technology has enabled candied fruits with the same raw materials to taste even more differently.
