  • WG5 on digestive amylases and starch digestion
  • WG6 on in silico (mathematical) models of digestion

Participation to these WG meetings will be free of charge, do not forget to confirm your participation when registering to the conference. In the “comments” box, please indicate to which WG meeting you’d like to participate (WG4 or WG5 or WG6).
