ABSTRACT
Production of Peanut Butter was done using roasted groundnuts, salt and yeast. The process involved roasting and grinding into fine paste, after which equal amount of honey and vegetable oil were added, sugar, salt, followed by powdered yolk of an egg was added as colouring agent. The product produced peanut butter was yellowish in colour, had a smooth and soft texture which spread easily on bread and had a fine peanut taste. It was put under observation for microbial growths for twelve weeks and microbial was observed at the end the eleventh week, thus giving it a shelf life of 11-12 weeks without preservative. When sodium bicarbonate was added the lifespan was extended to 20-25 weeks.
