Ginkgo seeds are composed of a fleshy outer seed coat, a hard middle seed coat (husk), a thin inner seed coat (coating), endosperm (kernel slices), and an embryo. The endosperm is the main edible part of ginkgo seeds. The fresh white fruit kernel is green like jade, light yellow or light green after cooking, with a slight bitter and astringent taste, eaten hot, soft and glutinous. In addition, when we pick ginkgo seeds, the annoying smell is actually the outer seed coat of ginkgo seeds, which contains butyric acid and heptanoic acid, and after breaking, it will emit the stench of fruit rotting, which can protect the seeds from being destroyed by the outside world.
