In‐Vitro Protein Digestibility of Dehydrated Protein Extract from Poultry Bone Residue

摘要

ABSTRACTIn‐vitro protein digestibility of freeze‐ or spray‐dried protein obtained from poultry bone residue by alkali extraction was evaluated by a multienzyme procedure. Digestibility of the dehydrated extracts was significantly lower than chicken breast muscle or mechanically de‐boned poultry. Digestibility of the spray‐dried extracts was about 3 higher than freeze‐dri
