Effects of mango peel powder on starch digestion and quality characteristics of bread

This study investigated effects of mango peel powder on starch digestion properties and quality characteristics of bread, and discussed underneath mechanisms. Starch digestion rate and extent of bread were evaluated in vitro, and bread quality characteristics, including moisture content, volume, color and texture, were evaluated. The results showed that adding mango peel powder could significantly reduce starch digestion rate and digestion extent in bread, and the reduction degree was positively related to the amount of mango peel powder applied. Bread moisture content was improved by mango peel powder, while bread volume was reduced. Bread color was also impacted, showing increased L*, a* and b* values. And incorporation of mango peel powder apparently affected bread texture, resulting in increased hardness and chewiness, as well as decreased cohesiveness. These influences were generally proportional to the amount of mango peel powder applied. When
