What is Chenpi?

Chenpi consists of the dried outer skin of mandarin oranges, most notably those grown in Xinhui. The peels are sun-dried and then stored to age over time. Fresh peel tastes slightly sweet, but the aging process develops a pungent and bitter aftertaste. In traditional Chinese herbology, the spice is considered to have a warm attribute. It is often cut into thin shreds before being added to dishes or teas.

Where does Chenpi come from?

The use of citrus peels in traditional medicine dates back to the Song dynasty, spanning seven hundred years. The practice grew popular during the Ming and Qing dynasties, with merchants from Xinhui shipping the product to other provinces. A famous doctor named Ye Gui prescribed it in the Erchen Tang decoction. The local industry brought wealth to Xinhui peasants, though it faced decline in the 1990s before regaining popularity through local associations.

What does Chenpi taste like?

The taste profile begins with a mild sweetness that quickly shifts to a sharp, pungent bitterness. This complexity comes from volatile oils within the peel, including compounds like nobiletin, hesperidin, tangeretin, and synephrine. The aroma is characteristic of dried citrus, with notes of carotene and cryptoxanthin contributing to its distinct scent and flavor depth.

How Chenpi is grown and processed

Production focuses on specific peeling and storage techniques, particularly in Xinhui. After harvesting, the peels are sun-dried and aged by storing them in dry conditions. Before use, they are soaked in cold water for up to thirty minutes to soften. The white pith is then gently scraped away to prepare the peel for cooking or medicinal extraction.
