WebJul 7, 2000 · Bread made with boiled malt flour (30%) had an improved crumb structure, crumb softness, water-holding capacity, and resistance to staling, as well as a fine malt flavor compared with the bread made with grain sorghum flour (30%). Consumers preferred the malted sorghum bread over the bread made with plain sorghum flour. WebJun 12, 2015 · What causes staling? For a long time it was believed that staling was due to dehydration but now it has been clearly determined that the issue comes from “crystallization” of the flour starch. Crystallization is caused by water leaving starch granules and going into spaces in between granules.
WebBread staling occurs most rapidly at 0–4°C. Retrogradation occurs more readily with amylose than with amylopectin since it is a smaller unbranched molecule; therefore the use of waxy starches (low amylose content) in foods can decrease the level of retrogradation ( Singh and Anderson, 2004 ). WebStaling, as it is applied to bakery foods, is a generic term covering a number of changes that occur in the products during normal storage. Consumers judge staleness by direct …
Ingredients affect crumb firming and moisture changes: 1. Fats slow staling by improving loaf volume. 2. Sweeteners slow staling directly by retaining moisture, and most other ingredients that increase absorption usually inhibit staling. 3. High-protein flours improve crumb softness by contributing to a larger loaf … See more Consumer testing, crumbliness, and water absorption are sometimes used to measure bread staling, but the most common method is compressibility.
