Polyelectrolyte complex of Aloe vera, chitosan, and alginate produced fibroblast and lymphocyte viabilities and migration.

Chitosan, sodium alginate and gel of Aloe vera (Aloe barbadensis Miller) were employed for the preparation of polyelectrolyte complexes at pH 4 and 6. FT-IR spectroscopy analysis showed evidence on complexes formation and incorporation of the Aloe vera gel. The ζ potential determination of the polyelectrolyte complexes revealed the presence of surface charges in the range of -20 to -24 mV, which results in stable systems.

Exploring the Potential of Mesquite Gum-Nopal Mucilage Mixtures: Physicochemical and Functional Properties.

Unlabelled: In this work the physicochemical and functional properties of mesquite gum (MG) and nopal mucilage (NM) mixtures (75-25, 50-50, 25-75) were evaluated and compared with those of the individual biopolymers. MG-NM mixtures exhibited more negative zeta potential (ZP) values than those displayed by MG and NM, with 75-25 MG-NM showing the most negative value (-14.92 mV at pH = 7.

Rheological properties of tamarind (Tamarindus indica L.) seed mucilage obtained by spray-drying as a novel source of hydrocolloid.

Tamarind seed mucilage (TSM) was extracted and obtained by spray drying. The power law model well described the rheological behavior of the TSM dispersions with determination coefficients R higher than 0.93.
