Research Summary

Initially, our research aimed at studying the modifications and interactions of two major macronutrients, carbohydrates and proteins, during storage and/or conventional and alternative thermal treatments of foods. The obtained results allowed the development of new analytical methods and the selection of a series of chemical indicators to evaluate the quality of heat-processed foods.

In recent years, the research lines have focused on the study of low glycemic index carbohydrates with prebiotic properties, given the interest shown towards the potential benefits of these carbohydrates in different aspects related to health not only by researchers and industry, but also by consumers. Therefore, currently, one of the main lines of work is the obtainment, characterization and evaluation of bioactive and technological properties of new carbohydrates and derivatives for subsequent use as food ingredients.

Much of our research activity is focused on the enzymatic synthesis and structural characterization of potential prebiotic oligosaccharides using different types of enzymes (commercial and new carbohydrate-modifying enzymes) and by-products of the food industry (chitosans, cheese permeate and pectins from orange, sunflower and artichoke) in order to improve the management of waste generated in the industries of fishing, dairy and fruit and vegetable processing.

In addition, different studies are carried out to optimize the fractionation, characterization and evaluation of bioactive (prebiotic, anti-adherent, anti-inflammatory, etc.) and technological (sweetness, stability during heat treatment and preservation, rheological properties, among others) properties of the new carbohydrates synthesized to elucidate their potential applications.
