Development and characterisation of gluten‐free potato bread

SummaryThe aim of this study was to develop a novel and entirely potato‐based staple bread. Bread‐making performance of individual potato components (starch, protein and fibre) were independently evaluated and optimised by their ternary mixture. Flours from yellow and purple potatoes were then incorporated up to 25% of full formula weight to maximise the utilisation of resources. Fresh tuber was further added up to 50% for the full benefits from potatoes. The excessive oven‐rising after the crust hardened was manipulated by delicately balancing the strong swelling power of potato starch, which effectively resolved the cracks on the crust. The resultant potato breads showed a typical bread appearance, loaf size, low porosity but high cell density crumb structure and unique favourable sensory qualities, especially those with 2% potato fibre or 30% fresh tuber. Potato breads staled quickly during storage, but reheating could reverse the bread staleness to a nearly freshly baked state.
