The results indicate that soluble cocoa fibre is an encouraging
option for replacing oil in a chocolate muffin formulation. The main
advantages were that adding soluble cocoa fibre gave muffins
higher moisture and a more tender and crumbly texture, as they
were more fragile than the control, and reduced the signs of
hardening during storage. Also, adding soluble cocoa fibre gave
a fair amount of colour. However, there are points that require
improvement, such as the loss of height, perception of bitter taste
and a certain surface stickiness. A study to attempt to correct the
height by reformulating the leavening agent or beating the egg
whites more before adding them to the batter and to correct the
lack of a typical chocolate flavour and colour by adding a small
quantity of cocoa to all the formulations would make it possible to
conduct a wide-ranging consumer acceptance study with information
on the very considerable fat reduction and high fibre
content of the new products
