The use of methanol and ethanol for the extraction of antioxidant compounds in Chia Seed (Salvia hispanica L.) is studied, but only the effect of a single concentration of these solvents was evaluated. However, factors such as the nature and the concentration of the solvents determines the content of phenolic compounds, the antioxidant capacity and...

Chia (Salvia hispanica L.) seeds contain antioxidants with great benefits for health and are widely used in the food industry. Antioxidants can be degraded by environmental factors, decreasing their biological activity. Their encapsulation in chitosan (CH) particles represents an alternative to protect them and increases their application. The enca...

Research background. Amaranth (Amaranthus hypochondriacus) flour produces films with excellent barrier properties against water vapor, allowing food preservation, but the mechanical properties are poor compared to synthetic films. One strategy to improve these properties is the incorporation of nanoparticles. The particles can also serve as a vehic...

Biodegradable films based on polymers from renewable resources have become a feasible technology to preserve the quality (texture, color, flavor) and safety of food. The addition of antimicrobial agents to films can prevent the growth of pathogenic microorganisms that affect meat and poultry products. In this study, a biodegradable film with sodium...

Nowadays, emerging technologies for food are the most studied, compared to the traditional food preservation. In this book some of the emerging technologies applied in the food industry are revised, such as irradiation that allows to improve food safety and shelf life; the advantages and some limitations of technology are presented, as well as the...

Metabolic syndrome comprises a cluster of diseases like hypertension, dyslipidemia, and insulin resistance, among others. Its treatment is based on lifestyle modification; however, this treatment often fails to improve metabolic syndrome indicators over the long term. In this work, sequences of some representative vegetable proteins were explored t...

Tepexi de Rodríguez is one of the municipalities with the highest rate of extreme poverty in Mexico. The agriculture and the marble extraction industry are the major sources of employment. This region has more than 15 processing factories of marble, where poor safety conditions of work, low salaries and pollution are common denominator. The marble...

Introducción: Se presentan los resultados de tres proyectos elaborados en el Instituto Tecnológico Superior de Tepexi durante los años 2014-2015, los cuales buscan el desarrollo de una de las regiones más pobres de México. Metodología: El primer proyecto consistió en la preparación de un producto de higiene bucal a partir de la planta shoquillo (R...
