Groundnut bran and groundnut skins

Description and recommendations

IMPORTANT INFORMATION: This datasheet is pending revision and updating; its contents are currently derived from FAO's Animal Feed Resources Information System (1991-2002) and from Bo Göhl's Tropical Feeds (1976-1982).

Common names

Groundnut skins, peanut skins, peanut bran, peanut skins

Synonyms

Arachis hypogaea L. subsp. oleifera A.Chev., Arachis nambyquarae Hoehne

Description

Groundut skins, which constitutes about 3% of the seed weight, are a by-product of the processing of groundnuts for human consumption. Peanut bran is a by-product of groundnut oil extraction. Both products contain the skins and variable amounts of seeds.
