Pectin in fruit jams formulations
The amount of pectin in fresh prepared fruit jams of
different formulations is shown in Table 2. There was no
significant difference in pectin content (p > 0.05) for all
fruit jams with the same treatment with the exception of
A. digitata L. jam that showed significantly higher pectin
content (0.82%). The higher pectin content in jam treated
with A. digitata L. powder (APP) and commercial pectin
(CPT) as a pectin source was due to high content of
pectin in A. digitata L powder and commercial pectin,
respectively. This observation is supported by the results
presented for A. digitata L. jam where the addition of
other pectin sources resulted in higher pectin level
beyond the recommended level (0.5%) of pectin as
suggested by Belitz and Grosch (1999) for jam. The
observation of the current study is consistent with the
hard texture exhibited by A. digitata L. jam reported by
Tiisekwa et al. (2002). These results show that A. digitata
