额外处女橄油 (EVOO) 具有益生菌性质,促进有益的肠道细菌,如乳酸菌和双菌. 这项研究发现,许多EVOO比胰岛素更有效地刺激肠道微生物群和短链脂肪酸生产.
科学领域:
- 营养科学 营养科学
- 微生物学 微生物学
- 食品科学 食品科学 食品科学
背景情况:
- 橄油是地中海饮食的关键组成部分,以其健康益处而闻名.
- 新兴研究表明,橄油的潜在益生菌作用.
- 益生菌选择性地刺激有益的肠道细菌,影响宿主健康.
研究的目的:
- 为了研究额外处女橄油 (EVOO) 的益生菌潜力.
- 评估单变种EVOO对肠道细菌群和短链脂肪酸 (SCFA) 生产的影响.
- 为了比较EVOO的益生菌活性与已知的益生菌inulin.
主要方法:
- 使用体外发酵系统来模拟肠道条件.
- 分析了来自五种意大利品种的20个单变种EVOO样本.
- 对特定细菌物种 (乳杆菌,双菌) 的选择性刺激和SCFA的产生进行了监测.
主要成果:
- 所有经过测试的EVOO都显示出对Lactobacillus spp.的选择性刺激,超过了inulin的效果.
- 特别是来自Raggia品种的EVOO样本显著增加了Bifidobacteria种群.
- 与对照组相比,在24小时后的所有EVOO发酵中,SCFA含量,包括酸和酸,显著增加.
结论:
- 大多数研究的EVOO具有显著的前生物活性.
- EVOO的益生菌潜力相当于或甚至比inulin更强.
- 可以认为EVOO是一种功能性食品成分,通过益生菌机制支持肠道健康.
