玄米 (BSG) 强化大麦基泡乳液 (BFE) 作为蛋糕中的有效脂肪替代品. 这些BSG增强的BFE提高了机械强度和热稳定性,成功取代了缩短而不会影响制品质量.
科学领域:
- 食品科学与技术 食品科学与技术
- 材料科学 材料科学 材料科学
- 类风病学 类风病学 类风病学
背景情况:
- 烤肉中的关键成分缩短,通常含有和脂肪.
- 开发更健康的脂肪替代品对于改善面包产品的营养状况至关重要.
- 基于比格尔的泡乳液 (BFE) 具有作为结构性脂肪替代品的潜力.
研究的目的:
- 开发和表征一种基于大麦的泡乳液 (BFE),使用单甘油油和玄米 (BSG).
- 评估不同BSG度对BFE特性的影响,并将其应用于饼中的缩短替代品.
主要方法:
- 配方BFEs具有不同的BSG含量 (0-0.5%).
- 描述BFE属性,包括机械强度,相稳定性,学和热稳定性.
- 用BFEs作为部分和完全替代缩短饼配方中的应用.
- 评估蛋糕的质量属性:特定重量,形态,多孔性,特定体积,水分,颜色和质地.
主要成果:
- 增加BSG显著提高了BFE的机械强度 (硬度,粘度,G'1Hz) 和相位稳定性.
- BFEs表现出伪塑性行为,具有更好的热稳定性 (增加融).
- 在饼干中,BFE成功取代了缩短 (50%和100%),而不会对或制品质量产生负面影响.
- 与没有BSG的配方相比,含有BSG的BFE表现出优异的功能角色复制.
结论:
- 玄米有效地增强了基于大的泡乳液,增强了它们的结构和热性质.
- 在面包店应用中,BFEs是可行的脂肪替代品,为缩短提供了营养上改进的替代品.
- 这项研究支持在制造更健康的面包制品时使用BSG修饰的BFE.
