ABSTRACT

Chemical and sensory evaluation of peanut butter using two varieties of peanut (arachis hypogea)

Two varieties of peanut (Arachis hypogea) used for peanut butter making are Valencia from Gombe in Northern part of Nigeria and Virginia from Ogoja in cross-River state of Nigeria. The peanut butter obtained was evaluated chemically and sensually to determine the variety that performed better. Proximate analyses were carried on the samples. The result of there analyses showed ash 5%, moisture 4.5%, and fat 40%. The properties evaluated include fixture, consistency. The organoleptic properties evaluated for are flavour. The Virginia (ogoya) variety is more acceptable than the Valencia (Gombe). This project has proved that peanut butter making is technically possible.
