蜂蜜干粉对面包面团热机械学、烘焙及老化特性的影响

Effect of honey powder on thermomechanical properties of dough, baking and staling properties of bread

  • 摘要: 采用Mixolab、质构仪和差式扫描量热仪(DSC)研究蜂蜜干粉对面包面团热机械学、烘焙和老化特性的影响。Mixolab实验表明,蜂蜜干粉对蔗糖的取代提高了面团的吸水率和稳定时间,当蜂蜜干粉取代比例超过50%时,蛋白质弱化值C1-C2和弱化度α显著增加(p<0.05);此外蜂蜜干粉会降低淀粉的回生值C5-C4,蜂蜜干粉的取代比例为100%时,C5-C4降低了21.03%。新鲜面包的烘焙数据表明,与空白组相比,蜂蜜干粉使得面包比容变大,硬度减小,当蜂蜜干粉的取代量为总蔗糖量的50%时,面包烘焙品质最佳。面包老化实验发现,蜂蜜干粉加入面包中,可以减小面包硬化速率和水分减少速率;长时间储藏使得面包的老化焓值△H增加,与空白组相比,面包储藏7d后,蜂蜜干粉取代比例为25%、50%、75%和100%时,使得老化焓值分别降低了4.93%、9.87%、16.92%和22.77%,这表明,蜂蜜干粉在面包中的应用可延缓淀粉回生,延长面包货架期。 

     

    Abstract: Mixolab, Texture Analyzer and Differential Scanning Calorimeter (DSC) were used to investigate the effect of honey powder on thermomechanical characteristics of dough, baking quality and staling properties of bread. Mixolab experiment showed that, compared to the control, honey powder increased the water absorption and stabilization time significantly. When the substitution level of honey powder was more than 50%, C1-C2 and αincreased significantly (p<0.05) . In addition, with the increasing replacement level of honey powder, C5-C4 decreased, compared to the control, C5-C4 was reduced by 21.03%. Baking quality of fresh bread showed that the specific volume of bread increased, while the hardness decreased. The bread made with 50% addition of honey powder showed the best baking performance. The staling of bread was investigated and it was found that, during storage, the bread containing honey powder had lower rate of hardness and water loss. During 7d storage, honey powder at 25%, 50%, 75% and 100% levels decreased △H by 4.93%, 9.87%, 16.92% and 22.77% respectively, showing that the addition of honey powder could delay starch retrogradation and prolong shelf life of bread.
