The value of Vitellaria fruit pulp beyond energy and heat generation

January-June 2023

The shea nut pulp (SNP) has been used minimally for energy and heat generation. There is increased generation of SNP as waste during the processing of the shea nut fruit (SNF) to butter. Although the pulp is sweet and eaten by human and birds, there is paucity of information on the composition and potential uses of the SNP. This study investigated Vitellaria fruit pulp for their total solids and biochemical components....
