L. Bravo et al., CHARACTERIZATION OF SYRUPS AND DIETARY FIBER OBTAINED FROM MESQUITE PODS (PROSOPIS-PALLIDA L), Journal of agricultural and food chemistry, 46(5), 1998, pp. 1727-1733
Milled mesquite pods (Prosopis pallida) were washed in a pilot plant w
ith water at two different weight:water ratios, times, and temperature
s to obtain aqueous extracts and solid residues. The extracts were con
centrated under two different conditions to obtain syrups or ''algarro
binas'', and the residues were dried and milled to yield dietary fiber
(DF) concentrates. Total soluble sugars, protein, ash, and polyphenol
ic compounds were analyzed in syrups and DF concentrates, as well as f
iber, starch, and fat in the fiber concentrates. The proximate composi
tion of mesquite pulp was also analyzed. The main components of mesqui
te pulp were dietary fiber (257.1 g/kg) and soluble sugars (539.5 g/kg
). Syrups were compared to three others commercialized locally in some
regions of Peru, showing less sucrose inversion than in the commercia
l ones and the same brown color. Of the two fiber products obtained, o
ne of them was a concentrate rich in total DF (801.9 g/kg) composed of
mainly insoluble fiber. The other product had a lower DF content (447
.7 g/kg) but a higher soluble sugar concentration (263.3 g/kg). The po
tential application of these products in the food industry is discusse
