Document Type : Original Article

Abstract

This study was carried out to investigate the effect of using
avocado or canta loupe puree as a fat substitution with the following
levels 0%, 25%, 50%, 75% and 100% on quality characteristics of
muffins. The results indicated that a significant increase in moisture as
substitution levels of both avocado or cantaloupe puree increased
relative to a significant lowered in fat content. The substitution of fat
with avocado or cantaloupe puree at different levels lowered the
weight, volume, height and specific volume of muffins. The texture
profile analysis (TPA) showed that both puree increase hardness and
resilience of the muffins formulated with 75% and 100% substitution
which more was pronounced in avocado puree substituted muffins
than control. The sensory evaluation of muffins showed that muffins
formulated with avocado (25, 50, 75 and 100%) showed darker color
of crumb compared to the control muffins, however, it was more
acceptable than the muffins formulated with cantaloupe in the other
quality properties. Therefore, avocado can be used as butter substitute
in bakery products, since quality properties of muffins were improved
by substitution of butter with avocado puree.
