Palliatives for enhancing the stability of beer flavor have been evaluated by organoleptic tests, but primarily by use of an accelerated aging technique, followed by estimation of staling substances using thiobarbituric acid (TBA). TBA has also been used to trace the quantities of carbonyl compounds and their precursors through malting and brewing and in beer treated with palliatives and substa...

Staling of bread is cause of significant product waste in the world. We 26 reviewed the literature of last 10 years with the aim to give an up-to-date overview on 27 processing/storage parameters, antistaling ingredients, sourdough technology, and 28 measurement methods of the staling phenomenon. Many researchers have been focusing their 29 interest on the selection of ingredients able to retar...

When a strain of bacteria is streaked on a nutrient agar or gelatin medium containing a large number of its own viable cells, no growth appears even after long incubation. Eijkman (1904) and Powers and Levine (1937) suggested that this phenomenon of "staling" was due to specific, autoinhibitory substances and that it might serve as a basis for selective and differential techniques in determinat...

F resh bakery products have been a staple food for humans for hundreds of years. Freshly baked products have a flavorful aroma, yeasty, sweet taste, and soft but resilient texture. However, the freshness of bakery products can be lost quickly over time. This loss of freshness is due to a series of slow chemical and physical changes that leads to progressive firming of the crumb, commonly referr...

“Pan de Muerto” is a traditional bread type, emblematic of Mexican bakery. This work’s objectives were defining its characteristics, determining the effect fat content, and storage conditions on staling, examining relative impact these crystallization starch retrogradation. Staling was evaluated via changes in Young’s modulus. Fat retrogradation studied considering thermal crystalline propertie...

• Gluten-free bread (GFB) staling was studied by an instrumental and sensory approach. Chickpea flour reduced moisture loss crumb hardness during 7 days of storage. Consumers described chickpea-based GFB as soft fresh with gluten-related disorders considered chickpea-psyllium-based ideally soft. its combination psyllium delayed staling. is generally recognized a product less than satisfying app...
