Which process occurs when starch is exposed to dry heat, breaking down to dextrin and turning golden brown?

Explanation:
When starch is heated with dry heat, the long starch molecules break down into shorter dextrin molecules, which gives a golden-brown color and a slight sweetness. This specific chemical change is known as dextrinisation. It relies on dry heat; moisture would drive other reactions instead. Caramelisation involves sugars alone and their breakdown, not starch. The Maillard reaction needs amino acids plus reducing sugars from proteins, not just starch. Roasting is a cooking method and can include dextrinisation, but the process described is the specific change of starch into dextrins.
