The molecular state of gelatinized starch in surplus bread affects bread recycling potential

نویسندگان

چکیده

Surplus bread is a major bakery side stream that should be strictly kept within the human food chain to reduce waste and ensure resource efficiency in baking processes. Optimally, surplus recycled as dough ingredient, however, this known detrimental volume texture of bread. The purpose study was investigate how gelatinized starch bread, untreated or enzymatically hydrolyzed, affects development, textural attributes. Starch hydrolyzed various degrees using commercial α-amylase amyloglucosidase. Bread hydrolysates containing different carbohydrate profiles (untreated, 75%, 57%, 26% remaining) were evaluated ingredients. More complete hydrolysis resulted better visco-elastic properties higher level, reduced water absorption by 13%. Nonetheless, breads hydrolysate with high-malto-oligosaccharides had lowest intrinsic hardness similar yield when compared control Furthermore, slurry, high-malto-oligosaccharides, crumb 28% staling rate 42%, increased specific 8%. present findings show enzymatic dramatically transforms impact starch. Thus, selecting correct bioprocessing approaches, recycling performance may significantly improved.

Browning indicators in bread.

Bread is the most important food in the Spanish household and represents the largest proportion of products produced by commercial bakeries. The browning indicators furosine, hydroxymethylfurfural (HMF), and color were determined to evaluate heat effects induced during manufacture of these foods. The breads analyzed were common, special, sliced toasted, and snack breads. Identical sample prepar...

Molecular Features of Wheat Endosperm Arabinoxylan Inclusion in Functional Bread

Arabinoxylan (AX) is a major dietary fibre component found in a variety of cereals. Numerous health benefits of arabinoxylans have been reported to be associated with their solubility and molecular features. The current study reports the development of a functional bread using a combination of AX-enriched material (AEM) and optimal commercial endoxylanase. The total AX content of bread was incr...
