Composition of cakes
It is clear from Table 4 that cakes prepared by replacing sugar
with stevioside, SO and additives and DFSP had higher moisture and
protein contents. The fat content of cakes with and without sugar
ranged between 27.2 and 28.4%. The cakes with sugar had 22.9%
sucrose while cakes with stevioside and SO, additives and DFSP had
negligible sucrose (p < 0.05). Use of DFSP increased the dietary fiber
content of cakes with SO and stevioside, additives by 5.0 times
(p < 0.05). Bakr (1997) carried out studies on the preparation of
acceptable, low energy, fiber enriched and diabetic jams, cakes and
biscuits using different formulas of sugar substitutes with the partial
replacement of wheat flour with bran as a source of dietary fiber.
They opined that highly nutritious and acceptable cakes and biscuits
for low energy supply and for diabetic subjects can be sweetened
with low level of aspartame in combination with fructose, sorbitol
and xylitol. Addition of wheat bran not only reduced both energy
value of these products and blood glucose but it also improved
peripheral insulin activity by its system modification.
