COVID-19 cases, hospitalizations, outpatients, and deaths in Mexico by ethnicity and state-level income.

Introduction: Mexico is one of the countries that is most affected by mortality due to COVID-19. Once infected, the indigenous population living in the lower-income states had worse outcomes. Our objectives were to analyze outcomes by ethnic group, and determine the association between state-level income and the incidence, hospitalizations, outpatients, and death rates per 100,000 population.

Development of gelatin/carboxymethylcellulose active films containing Hass avocado peel extract and their application as a packaging for the preservation of berries.

This study aimed to evaluate the effect of incorporating different concentrations (0, 200, 300, and 400 mg L) of avocado peel extracts (EE-AP) on the physicochemical properties and antifungal activity of gelatin-carboxymethylcellulose (Gel-CMC) films and their applicability in berry preservation. The results showed that incorporating EE-AP was compatible with the Gel-CMC film and enhanced the mechanical properties without affecting the integrity and thermal properties. The 200 mg L of EE-AP concentration on films offered the best barrier properties against water vapor (2.

Tapioca starch-galactomannan systems: Comparative studies of rheological and textural properties.

Rheological properties of tapioca starch-galactomannan mixtures at different concentrations (0, 0.3, 0.6 and 1.

Starch-guar gum extrudates: microstructure, physicochemical properties and in-vitro digestion.

Starch-guar gum mixtures were obtained by extrusion using a three-variable Box-Behnken statistic design. Morphology, expansion index, viscosity, crystallinity and digestion in vitro of the extruded samples were analyzed through response surface methodology (RSM). The extrusion temperature and the moisture content were the factors that significantly affected the physicochemical properties of the samples.
