RESULTS AND DISCUSSION
General composition of guava was 74-87% moisture,
0.8-1.5% protein, 4.2-11.1 total sugars, 2.0-7.2%
crude fiber, 0.4-0.7% fat, and 0.5-1.0% ash. The
composition of guava varies significantly with variety,
stage of maturity, and season (7), but scarce information
about specific physicochemical composition of guava is
reported.
Dietary Fiber, Indigestible Fraction, and Polyphenols.
The results of DF determinations in peel and
pulp of Psidium guajava are shown in Table 1. The peel
and pulp of guava showed a total DF content in the
range 48.00-49.00 g/100 g of dry matter (dm) and
therefore met the first requirement for consideration as
an antioxidant dietary fiber (AODF) (6). The main
fraction was iDF (96-97% of tDF) in both cases. Nahar
