Kekse mit Chemie?

Das macht Braten und Kekse knusprig braun: Philipp Spitzer verrät Spannendes aus der Wissenschaftsküche

Für die einen ist das Backen an sich schon eine Wissenschaft. Für die anderen erst recht der Vorgang, der bewirkt, dass uns Braten und Backwerk zu Weihnachten auf der Zunge zergehen. Chemie-Didaktiker Philipp Spitzer weiß Genaues. So sorgt die sogenannte Maillard-Reaktion dafür, dass sowohl Truthahn als auch Lebkuchen knusprig braun werden. „Man könnte es als Weihnachts-Reaktion bezeichnen“, schmunzelt Spitzer. Und wenn Kekse zerbröseln, ist Physik mit im Spiel. „Frisch aus dem Ofen saugt das Gebäck Feuchtigkeit an, es entsteht Spannung und das Backwerk bricht.“
