Food and beverages (non-medicinal):
The seeds of Castanopsis eyrei are edible. In parts of southern China they are traditionally collected, lightly boiled or roasted, and may be milled into flour; the flour is used to make steamed cakes, dumplings, or a coarse “powder” added to porridges and desserts. Seeds are also fermented into a distiller’s mash for baijiu-type spirits in local regions, with distillation yielding a neutral spirit typically aged in earthenware. No health or efficacy claims are implied.

Properties relevant to use:
The seeds are starchy with moderate soluble sugars; roasted seeds develop a sweet aroma. Amylose content (typ. ~20–30%) yields a product that gelatinizes readily and produces a gelatinized paste suitable for baking or steaming. The pericarp/telope is hard and brittle, facilitating cracking with minimal breakage.

Standards and regulation:
Edible-seed products (flour and spirits) in China are produced under national hygiene standards for food (e.g., GB 14881 for general food hygiene) and for liquor (GB/T 10781 and related specifications); specifics vary by province and product type.

Sustainability and sourcing:
Seeds are primarily wild-collected from natural forests in Hunan, Jiangxi, Fujian, Zhejiang, and Anhui. Sustainable practice involves staggered harvesting to protect regeneration and maintain wildlife seed caches; local gathering commonly involves handpicking and localized transport, with no industrial orchard scale reported.
