LABORATORYPOLIFIBAN (non-extractable polyphenols, antioxdiants and dietary fibre in health)
We are looking for a candidate from outside Spain who plan to submit applications for independent research fellowships through the mobility program Marie Skłodowska Curie Individual Fellowship (MSCA-IF). The candidate would join the POLIBIBAN (non-extractable polyphenols, antioxidants and dietary fibre in health), at the Department of Metabolism and Nutrition, of the Institute of Food Science, Technology and Nutrition (ICTAN-CSIC), in Madrid, Spain.
The Spanish National Research Council (CSIC) is the largest public institution dedicated to research in Spain and the third largest in Europe. Its research is driven by more than 100 hundreds centres and institutes and its more than 15,000 staff, of whom more than 3,000 are staff researchers and the same number again are doctors and scientists who are still training. CSIC has 6% of all the staff dedicated to Research and Development in Spain, and they generate approximately 20% of all scientific production in the country.
ICTAN is placed in the premises of CSIC Campus at the Ciudad Universitaria in Madrid. ICTAN is willing to deploy R&D activities in the forefront of international knowledge and become a worldwide reference center to meet society needs in the area of food production and human well-being through nutrition. For this, it has a total staff of more than 120 people, as well as relevant facilities: Unit of Human nutrition in order to develop nutritional clinical trials; Unit of Sensory Analysis; a Pilot Plan for Food Technology; and a Unit of Analytical Services (with equipments such as mass spectrometers), among others.
Research lines of the research team
POLIFIBAN research team is focused on the study of dietary polyphenols, with especial emphasis to the so-called non-extractable polyphenols. These compounds, present if the food matrix as polymeric structures or linked to polymeric molecules such as dietary fibre (for this reason they are also called macromolecular antioxidants) are common in plant foods and they contribute to the daily intake of polyphenols. Moreover, preclinical and clinical studies have shown relevant health effects of non-extractable polyphenols rich matrixes. Nevertheless, they are still scarcely studied in the field of dietary polyphenols.
Our research team explores these compounds from a multi-disciplinary perspective, including characterization in foods, identification of new sources (including byproducts) for the production new ingredients; evaluation of in vitro bioaccessibility; evaluation of the metabolic fate of these compounds through clinical studies; evaluation of the health effects of these compounds by performing nutritional clinical trials.
We are looking for a junior scientist with experience in the field of food science and nutrition in order to join research lines through MSCA-IF 2021 funding. Potential candidates please send a CV together with a motivation letter to Dr. Jara Pérez-Jiménez (email@example.com)
