Sugar plays an important role in both the flavour and structure of confectionery. Targets have been set to reduce sugar; however, common strategies often result in changes in flavour and consumer rejection. In this study, an approach was developed to reduce sugar in confectionery gels by aeration, without significantly affecting perceived chewiness. Gelatine based gels with a 23% and 38% reduction in density were formulated using aeration. Mean bubble size was consistent across all gels (0.05-0.06 mm). Time-intensity sensory evaluation was carried out by a trained sensory panel (n = 10). With aeration, no significant difference in overall flavour perception was observed in the 23% and 38% reduced sugar and aroma gels. Air inclusions create a greater surface area, therefore accelerating mass transfer of volatiles and release of sucrose at the food-saliva interface. Consequently, we propose that less calorie dense products can be produced without compromising flavour by using gel aeration technologies.
糖在糖果的味道和结构中都起着重要作用。已经设定了目标来减少糖的含量;然而,常见的方法通常会导致味道的改变和消费者的拒绝。在这项研究中,开发了一种通过充气来减少糖果凝胶中糖含量的方法,而不会显著影响可咀嚼性的感知。使用充气法配制了密度降低 23%和 38%的基于明胶的凝胶。所有凝胶的平均气泡大小均保持一致(0.05-0.06 毫米)。通过受过训练的感官小组(n=10)进行了时间强度感官评估。通过充气,在 23%和 38%低糖和低香凝胶中,整体风味感知没有明显差异。空气夹带会产生更大的表面积,从而加速挥发性物质的质量转移和蔗糖在食物-唾液界面的释放。因此,我们提出,通过使用凝胶充气技术,可以在不影响风味的情况下生产出卡路里密度更低的产品。
