Abstract

- selection of the raw material and agreement with IITA
- development of new methods and modificiation of existing methods
- proximal charcaterization : moisture content, titratable acidity, pH, minerals in the flours (P,K,Ca,Zn,Cr,Pb,Se) and phosphorus in starches, free amino acids in flours, soluble sugars, IP6 phytates;
- rheological characterization of raw and cooked pulps using uniaxial texturometer by relaxation;
- rheological characterization of the pulps by dynamical mecanical analysisat constant strain rate;
- rheological characterization of the gelatinized starches by dynamical mechanical analysis (frequency sweep)
- rheological characterization by viscoamylographic profiles (RVA) in the rheometer starch cell;
- morphological and thermal characterization (lazer sizer and DSC)
- digestibility by enzymatic hydrolysis
- starch content by enzymatic hydrolysis

Perspectives

- scientific valorization (3 papers under redaction + the data produced by molecular starch analysis done at INRA under discussion)
- discussions for further collaboration under progress
