Shorea stenoptera

Borneo tallow nut

A tropical tree 6-15 m high with 5-cm nuts. The kernels are enclosed in a thin, brittle case set in an acornlike cup with winglike attachments that enable the nut to fall clear of the parent tree. The nuts are collected from the ground and dried in the sun until the shells are sufficiently brittle to be separated from the kernels by pounding in rice mortars. The seed is usually solvent extracted. The meal, though nontoxic, contains tannic acid and should therefore be used at low levels. It cannot be fed to chicks, and diets for layers should include not more than 10% as higher levels will produce eggs with greenish brown yolks. Similar meals are made from other Shorea species.
