- Description:
WALNUTS - Walnuts are the rounded, single-seeded stone fruits of the walnut tree native to southern Europe, which is a member of Juglandaceae family. The walnut is enclosed in a green, leathery, fleshy husk, which is inedible. Removal of the husk reveals the wrinkly walnut shell, which is in two halves, and encloses the kernel, which is likewise in two halves separated by a partition. The seed kernels are enclosed in a brown seed coat, which contains antioxidants. The antioxidants protect the oil-rich seed from atmospheric oxygen so preventing rancidity (oxidative rancidity).
Walnuts are shell fruit (nut types). Because of their similar characteristics with regard to transport, particularly their high oil content, their requirements regarding care during storage and transport are the same as those of oil-bearing seeds/fruits.
