WP6 - Model food applicability



Leader: Angelo Visconti

Contact details:

Address: Consiglio Nazionale della Ricerche, Instituto di Scienze delle Produzioni Alimentari (CNR-ISPA)
Country: Italy

Phone: +39 08 05 92 93 33

Activity type: RTD
Participants short name:INRA, ADRIA, CNR-ISPA, IFR, KEKI, SOREDAB

To assess the performances of some experimental food models produced in WPs 2-5 in terms of bioavailability of nutrients, phytochemicals and toxicants, and microbial food safety and quality.

Role of participants and methodology:
CNR-ISPA (WP leader): will perform all activities described in tasks 6.4.1 and 6.4.2 with the exception of those performed by ADRIA, and all activities described in task 6.4.3 with the exception of the in vitro digestion experiments (performed by IFR who will deliver biofluids to CNR-ISPA for the analyses).
SOREDAB will perform research activities described in tasks 6.1 and 6.2.
IFR will perform in vitro digestion studies (task 6.3.1) and analyse selected biomarkers in biofluids.
INRA and KEKI will be involved in task 6.3.2 for: i) peptide identification in biofluids by mass spectrometry (INRA) and SDS-PAGE, 2D electrophoresis, immuno-blotting, HPLC, ELISA (KEKI); ii) in vivo studies on food model’s digestion on a rat model (KEKI), and evaluation of the potential absorption of selected biomarkers in a minipig model (INRA). INRA will also perform the human study (task 6.3.3), and could share with KEKI part of the specific marker analysis.
ADRIA will work on the: i) detection of Bacillus species (task 6.4.1); ii) PCR-TTGE on dairy products (task 6.4.2); and iii) implementation of already existing predictive microbiology and food model aided design tools (task 6.4.4).
