Youxi Kumquat, also known as kumquat, gold bullet. Every year after the winter, it gradually matures, and the winter lunar month is the peak season. The fruit is oval, and the golden and moist particles, such as the size of the thumb, are the ones with larger fruit shape, superior quality and highest economic value. The citrus peel of Youxi is smooth and shiny, and the flesh is firm and full, crisp and juicy, sweet and sour, pleasant and pleasing.

Since the peel of kumquat is thick and brittle, and it is difficult to peel off from the flesh, people usually eat the flesh together and have a high edible rate. This method of eating is conducive to the full absorption of its nutrients. Because its peel and pulp are rich in total sugar, total acid, carotenoids and vitamins A, B, C and P, its nutrient content ranks among the best in citrus fruits.
