- 食品科学 食品科学 食品科学
- 合体和表面化学
- 生物聚合物修饰修饰
背景情况:
- 酸 (SC) 是一种常见的食品乳化剂.
- 由于其敏感性,β-胡卜素需要在乳液中稳定.
- 香料化物具有修改基于蛋白质的乳化剂的潜力.
研究的目的:
- 为了研究使用香料化物 (SA) 作为乳化剂对甲酸盐 (SC) 的修饰.
- 为了稳定β-胡卜素 (β-胡卜素) 乳液.
- 阐明SC和SA之间的结合机制.
主要方法:
- 用甲 (CA),p-anisaldehyde (PAA),n-heptanal (NHA) 和citronellal (CNA) 修改甲酸盐的方法.
- 使用结合机制研究 (结,希夫基反应) 描述SC-SA相互作用.
- 评估SC的结构变化,表面疏水性和乳化特性.
主要成果:
- SA与SC的结合主要是通过非共价相互作用,特别是键.
- 丁甲 (CA) 可以通过希夫基反应与SC形成共价键.
