The main production cost of 1.1 kilograms of Xinhui tangerine peel and new peel ≈ (the price of 1 kilogram of fresh fruit and the processing cost of 1 kilogram of fresh fruit) The processing cost (cleaning, peeling, and drying) of a pound of Xinhui mandarins is about 1.2 yuan. Then the cost of new Tianma hides (in the first year) was approximately: (12 1.2) X 20 = 264 yuan/jin. There are many factors that contribute to the price of tangerine peel, the most basic of which are three: cultivation in the place of origin, processing and production, and storage and aging.

2. As we all know, new tangerine peel needs to be aged for three years before it can be called real tangerine peel. According to the characteristics of Xinhui tangerine peel, "the longer it ages, the better". The longer the tangerine peel is aged, the higher its value and the price will increase accordingly. It is generally accepted that Xinhui tangerine peel has an annual growth rate of about 20% in the first three years from new peel to tangerine peel, and after becoming tangerine peel, the annual value increase is about 30%.

1. Xinhui tangerine peel has a regular three-petal shape, and the pieces are rolled up. In terms of color, among the real Xinhui tangerine peels, the inner surface of the younger tangerine peel is snow white or yellowish white, and the outer surface is pig-like. The beard pattern is bright red or dark red in color; the inner capsule of old tangerine peel is naturally peeled off due to weathering, and the pig beard pattern is obvious on the inner and outer surfaces, which is tan or even black. But no matter how old it is, it is clean and distinct, with clear texture and luster. Due to the different origins of the tangerine peel from other places, the color of the tangerine peel is not uniform, ranging from cyan, yellow, and red, and the color may be dark or light. The inner capsule is smooth without the feeling of falling off, and the wrinkles are uneven.

2. Judging from the skin shape, the base of the authentic Xinhui tangerine peel is connected, with regular three-petal shape, and the pieces are rolled up. After decades of aging, if the shape of tangerine peel is still intact with three petals, it is considered the best. On the other hand, dried tangerine peel from other places is mostly irregular and fragmented. "Oil chamber" is a term in the tangerine peel industry. There are countless uniformly sized and concave oil spots on the surface of Xinhui tangerine peel, and the shrinkage is very obvious, which is called "oil chamber". The higher the integrity of the oil chamber, the higher the active substances such as hesperidin contained in tangerine peel, and the better the medicinal health-preserving effect. The oil spots of tangerine peel from other places are unevenly distributed, smaller in number and of different sizes. In terms of tea color, the younger tangerine peels in Xinhui tangerine peels are greenish-yellow (or even cyan) in color. The tea color of old tangerine peel is yellow-red (or even red), and the tea color is golden and transparent. In other places, tangerine peel with different maturity levels is used to make tea, and the color of the tea soup is also different.
