基于植物 (PB) 和基于肉 (MB) 的汉堡在组成和行为上有很大的不同. 肉汉堡表现出优越的结构强度,而基于植物的选择在复制肉类肉类方面面临挑战.
科学领域:
- 食品科学 食品科学 食品科学
- 分析化学 分析化学
- 生物化学 生物化学
背景情况:
- 植物性 (PB) 汉堡是传统肉类 (MB) 汉堡的越来越受欢迎的替代品.
- 了解组成和结构上的差异对于提高PB产品质量至关重要.
研究的目的:
- 综合分析和比较PB和MB汉堡的化学和物理化学特性.
- 评估各种方法对汉堡特性的影响.
- 确定影响纹理和结构完整性的关键因素.
主要方法:
- 高性能液体染色学-双重质谱法 (HPLC-MS/MS) 用于化学分析.
- 物理化学分析包括损失,收缩,pH值,水分,水容量,颜色和质地.
- 主要组件分析 (PCA) 用于数据解释.
主要成果:
- MB汉堡具有更高水平的氨基酸和脂,有助于更大的结构强度.
- PB汉堡含有丰富的黄酸,酸和有机酸,具有抗氧化功效,但结构支持有限.
- 微波显著改变了汉堡的特性,增加了损失和硬度,特别是在PB配方中.
- 与PB汉堡相比,MB汉堡的pH值较低,水容量降低,损耗较高,质地明显更坚固.
结论:
- PB和MB汉堡之间的内在组成差异是行为和最终产品属性的变化的主要驱动因素.
- 在实现MB对应产品的纹理和结构品质方面,PB产品面临着重大挑战.
- 需要对配方策略进行进一步的研究,以增强植物性肉类替代品的纹理特性.

Classifying Matter by Composition
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or...
