, eau, donc la formation des bulles, accompagnée par une baisse de la température du produit, de la teneur en eau, et donc une augmentation de la température de la transition vitreuse Tg. C'est un phénomène complexe qui englobe la dynamique de nucléation, de croissance, de coalescence et de rupture des bulles dans une matrice viscoélastique, puis la solidification, voire l'effondrement à proximité de Tg. A l'heure actuelle, aucun modèle déterministe n'est disponible pour décrire ces phénomènes conjointement, En outre, un modèle déterministe serait trop complexe et ne pourrait être couplé avec le modèle mécanistique du logiciel de simulation d'extrusion bi-vis (Ludovic ® ), afin de prédire directement la structure cellulaire des mousses amylacées
