What You Need to Know
Sun-drying reduces moisture content below 10%, enabling rapid heat transfer during roasting where Maillard reactions (between reducing sugars and amino acids) produce melanoidins at 140-160°C. Buckwheat's high rutin content (quercetin-3-rutinoside) undergoes thermal degradation to quercetin, contributing bitterness.
Essential for achieving the characteristic snap and nutty flavor in fasting foods like 'vrat ke papad', serving as a textural contrast to soft buckwheat preparations.
