Group of Biophysical Approaches to Food, Food Processing and Preservation (FoodCRYOPHYS)

Description

Objetives

Study of interesting questions in Food Sciences through Biophysics techniques and methods. Physical aspects such as food and biological systems behavior under low temperature and high pressure are specially considered. This is, by nature, a group with interdisciplinary vocation, both in the questions considered and in the methodology employed. Being a small and emergent group, a good part of its activity is based in collaborative relations.

Research Lines

Ice crystal dynamics and glassy state in low-water content systems
Native and high hydrostatic pressure modified polysaccharides characterization (starch, cellulose, chitosan)
Proteins and enzymes at high pressure
Identification, quantification and controlled delivery of natural antioxidants

Skills

Identification, characterization and design of applications of cryoactive and ice crystal formation and growth modulator substances.
Study of the effect of physical and chemical treatments on food microstructure and related properties.
Vehiculization of nutritional and pharmaceutical interest substances (oligoelements, antioxidants) through matrices built of polysaccharides. Natural antioxidant characterization.
Proteins and enzymes at high pressure
Development and characterization of food products based on polysaccharides.
Design of high hydrostatic pressure processes to induce food modifications or to eliminate parasitic or microbiological risks.
