Apricot jam sugars were sucrose (22.49%), glucose (21.04%) and
fructose (21.34%). The initial total sugars content of jam decreased
by 5.52%, 9.02% and 7.46% after 60 days of storage at 5 C, 25 C,
and 37 C, respectively (Table 3). Statistical analysis revealed that
the interaction time–temperature factor had significant effect
(p < 0.05) on these individual sugars. Chauhan, Archana, Singh,
Raju, and Bawa (2012) indicated that the total sugar content of
the coconut jam decreased by 0.56% and 0.87% after storage for
6 months at 28 C and 37 C, respectively.
In our experiment, fructose levels decreased by 7.26% and 7.12%
after 60 days at 5 C and 25 C, respectively. However, for the samples
stored at 37 C, fructose content decreased significantly at day
twenty (7.49%) but increased after storage for 40 and 60 days. This
increase can be explained by the hydrolysis of sucrose. The sucrose
content decreased by 19.79% at 37 C after 60 days while it decreased
only by 6.49% at 5 C.
