The effect of Arabic gum on frozen dough properties and the sensory assessments of the bread produced

The use of hydrocolloids in frozen dough has become frequent as bread improvers due to their anti‐staling effect. Nevertheless, the impact of both different frozen storage and Arabic gum level in non‐prefermented flat dough with following thawing procedure have not been studied. This work intended to study the effect of three different ratio of Arabic gum on rheological properties of 1, 7, and 30 days of frozen storage and the quality of the bread made from. In order to gain the least detrimental effects on gluten network, we used rapid rate freezing and microwave heating in thawing stage. Rheological results showed that the unfrozen samples to which Arabic gum had been added rendered the highest resistance to extension. The resistance of gum fortified samples were less than fresh dough, however the decline was not significant in 3.0% Arabic gum dough kept in a month storage (p > .05). The similar findings were obtained for extensibility and adhesiveness; in which the maximum incorporation of Arabic gum lessen the destructive impact of long freezing storage. Addition of 3% gum could be able to retard staling through an increment in hydrophilic bonds between water molecules and amylose during thawing (p
