| Sumario: | Composition and bioactive properties of x`kijit fruit [
Renealmia alpinia
(Rottb.)
Maas] pulp and peel is unknown so far
.
Therefore, the objective of this study was to
evaluate physicochemical, and nutritional characteristics, bioactive compounds and
antioxidant activity of peel, pulp of the fruit (x`kijit fruit). The fruit pulp was higher in
soluble solids (10.53°Brix) and pH (6.2), while the peel had lower pH (3.9) and soluble
solids (2.3°Brix). The protein and fat contents were higher in pulp with values 4.2 and
8.6%, respectively. Vitamin C, flavonoids, phenolic compounds, and carotenoids were
higher in pulp (28.3 mg ascorbic acid.100 g
-1
FW, 567.8 mg catechin.100 g
-1
FW, 102.4 mg
GAE.100 g
-1
FW, and 332 μg of carotenoid.100 g
-1
FW, respectively) than peel. However,
the peel was higher in anthocyanins (181.4 mg of cyanidin.100 g
-1
FW), yielding an
antioxidant activity of 23.3mMFe
2+
.100 g

. The x`kijit fruit demonstrated to have an
important nutritional composition and a high antioxidant activity.
