The replacement of fat up to 25 g/100 g by CMG in pound cakes
presented no significant difference compared to the reference
formulation for the parameter firmness, until day 14.
The results show that 25 g/100 g of fat substitution in pound
cakes is feasible, as we obtained a product with unaltered technological
characteristics, which can be marketed with a specific “fat
reduction” functional claim.
As the vegetable fat was substituted by chia mucilage gel (CMG),
prepared by hydrating lyophilized chia mucilage (LCM) with tap
water (3 g/100 g aqueous solution), and due to the low fat content
in LCM (3.20 g/100 g e Table 2), its contribution to the final fat
content was not significant. Thus, the reduction of fat was effectively
of 25 g/100 g in the final product.
Additionally, cakes were produced with no requirement of additives
or other ingredients, besides CMG, to supply the reduction
of fat, which can also be related with the concept of “clean label”.
Further studies should be done characterizing the proximal
composition and sensory acceptance of the fat-reduced pound
cake, in comparison to the reference.
