Research lines

The research activity of the Food and Health Omics Group (CF1) is based on three pillars (Environmental Sustainability, Food Quality and Health) with a common denominator which is the use of different omics techniques (metabolomics, proteomics, transcriptomics) as an essential tool to understand the underlying molecular mechanisms present in food after the different effects to be studied.


In turn, each pillar is subdivided into several differentiated lines of research:

Environmental sustainability

  • ​Study of the distribution and bioaccumulation of organic pollutants (both emerging and persistent) in the early stages of primary food production.
  • ​Evaluation of the use of animal waste (manure and bags) as natural fertilizers from the circular economy perspective. Testing the effect of different physical, chemical and microbiological treatments on its polluting load and the effect of its subsequent application on cultivated soils, groundwater and surface water and the agro-food products obtained.

Food Quality

  • ​Study of the molecular mechanisms that modulate the response of the fermentative microbiota of wines (both yeasts and lactic bacteria) to the presence of residues of phytosanitary products (active substances and auxiliaries) in the must. Evaluation of its impact on ethnological parameters and on the sensory quality of the wines obtained (aroma and colour ).
  • ​ Study of the chemical, enzymatic and microbiological mechanisms involved in the generation and subsequent evolution of the aroma during the technological processing of various food origins (with special emphasis on products obtained from vegetables: wine and oil), as well as its stability, including the development of strategies to minimize off-flavours.
  • ​Chemical and functional characterization of various raw materials (grapes, olives, strawberries, pistachios, honey, etc.) and agri-food products (mainly wine and oil).


  • ​Identification of biomarkers of environmental contamination in biological samples from various sectors of the highly vulnerable population (pregnant women, babies, etc.) as well as game species, pets and birds.
  • ​Identification of biomarkers of positive effects on the health of a population with Type 2 diabetes mellitus with dietary supplementation with virgin olive oil obtained with native Galician varieties by conducting randomized clinical trials.
  • Bio accessibility, bioavailability and bioactivity studies (antioxidant, antidiabetic, antihypertensive, neurodegenerative, etc.) of functional foods through or use of static and dynamic models of in vitro gastrointestinal digestion.
