Abstract
Cocoa butter a salient ingredient in the chocolate recipe, imparts desirable properties to the
chocolate product unlike other vegetable oils. The unsteady supply and hike in price made
chocolate producers seek alternatives to cocoa butter. The EU passed a legislation that allows
the use of 5% of cocoa butter equivalent on product base in chocolate production. This study
was to formulate cocoa butter equivalent from shea stearin and palm olein and to evaluate the
magnitude of sensorial difference and preference of chocolate made with the cocoa butter
equivalent. Response Surface Method was used to obtain various ratios of shea stearin and
palm olein to use in chocolate formulation. Specific gravity and Refractive indices of the
various oils as well as their peroxide value (PV) and free fatty acid (FFA) value were
analysed. PV and FFA values of all oils used in the chocolate formulation were within the
acceptable limits of below 10meq for PV and not more than 1.75% for FFA. Panellists
observed significant difference between chocolates made with 5% CBEs and that made with
CB only. However, there was no significant difference in panellists acceptance/preference of
chocolates made with either CB or CBEs. This may imply that CBE formulated could
develop consumer acceptable chocolate
