Physicochemical Characterization of Resistant Starch Type-III (RS3) Obtained by Autoclaving Malanga () Flour and Corn Starch.

The feasibility of obtaining resistant starch type III (RS3) from malanga flour (), as an unconventional source of starch, was evaluated using the hydrothermal treatment of autoclaving. The physicochemical characterization of RS3 made from malanga flour was carried out through the evaluation of the chemical composition, color attributes, and thermal properties. In addition, the contents of the total starch, available starch, resistant starch, and retrograded resistant starch were determined by in vitro enzymatic tests.

Chitosan Films Obtained from (Girard) and Its Evaluation on Quality Attributes in Sausages during Storage.

High molecular weight chitosan (≈322 kDa) was obtained from chitin isolated from (Girard) to produced biodegradable films. Their physicochemical, mechanical and water vapor permeability (WVP) properties were compared against commercial chitosan films with different molecular weights. chitosan films (CFBM) exhibited similar physicochemical and mechanical characteristics to those of commercial chitosans.
