Romain Jeantet
Présentation
Mon activité de recherche s’inscrit dans des problématiques de génie des procédés appliquées aux matrices lait et ovoproduits. Elle est principalement orientée sur l’étude des transferts (matière, chaleur), en intégrant une expertise croissante en physicochimie pour la compréhension des phénomènes. Depuis 1993, j’ai été impliqué dans trois thématiques, en relation avec l’optimisation de procédés, la sécurisation et la maîtrise des propriétés des produits : - une thématique génie des séparations ayant pour objet l’étude et l’optimisation de transferts de matière en nanofiltration tangentielle (1993-2001) ; - une thématique pluridisciplinaire concernant l’étude des opérations de stabilisation thermique et non thermique appliqués aux matrices ovoproduits et lait (1998-2004, puis 2012-…) ; - une thématique opérations de concentration-déconcentration incluant la concentration, le séchage, le stockage et l’étude du mélange /réhydratation, puis de la digestion de bases laitières (depuis 2003)
