Proximate compositions
The energy provided by the jams was rather high (266–
274 kcal/100 g) (Table 1). Strawberry jams provide the highest
energy while the grape jams gave the lowest even though these
differences are not different statistically. Strawberry only provides
approximately 4.89 kcal/100 g (Giampieri et al., 2012) of
energy which is much lesser than reported in this study for
strawberry jam. The difference in the energy content between
both the strawberry and strawberry jam could be attributed
to the addition of sugar during the jam making process as it
is a great source of energy (389 kcal/100 g) (US Department
of Agriculture (USDA, 2011).
