科学领域:
- 食品科学 食品科学 食品科学
- 营养科学 营养科学
- 微生物学 微生物学
背景情况:
- 果蔬果汁中的多醇在加工和消化过程中容易降解.
- 了解多的生物可访问性和肠道微生物群的生物转化对于优化健康益处至关重要.
研究的目的:
- 调查非热 (高压加工) 和热 (高温短时间) 杀菌对多生物可访问性的影响.
- 为了分析人类肠道微生物群在巴氏杀菌后对多的生物转化.
主要方法:
- 水果和蔬菜果汁经过未经处理的,非热或热巴氏杀菌.
- 样品经过体外胃肠道消化和结肠发酵.
- 聚醇及其代谢物用液体染色学质谱法 (LC-MS) 量化.
主要成果:
- 这两种巴氏杀菌方法都提供了对聚醇降解的保护.
- 与未经处理的 (17%) 和非热处理的 (21%) 滑水相比,热处理导致多生物可访问性 (44%) 增加了两倍以上.
- 肠道微生物群在很大程度上将原生多 (83-87%) 转化为催化剂,热处理增强了代谢物生成.
结论:
- 热巴氏杀菌显著改善了多的生物可访问性和随后的肠道微生物群在牛奶中的生物转化.
