背景情况:
- 益生菌,如果糖寡糖 (FOSs) 和银糖寡糖 (GOSs),有益于肠道健康,但它们的食物含量数据有限.
- 了解益生菌成分对于评估饮食摄入量和健康影响至关重要.
研究的目的:
- 在35种不同的食品中量化FOS (基糖,尼糖,1F-β-果酸尼糖) 和GOS (拉菲糖,糖).
- 估计意大利人口每日摄入这些益生菌的摄入量.
主要方法:
- 食品样本使用高性能离子交换染色学与脉冲电压检测 (HPAEC-PAD) 分析了益生菌含量.
- 用100名健康的意大利成年人的食物频率问卷数据估计了益生菌摄入量.
主要成果:

01:27Microbes in the Production of Fermented Foods
Lactic acid bacteria (LAB) and molds are instrumental in fermenting plant-based foods to enhance preservation and ensure year-round availability. These microbial processes convert plant carbohydrates into organic acids and other metabolites that inhibit spoilage organisms and contribute to the sensory qualities of the final product.In sauerkraut production, cabbage goes through a microbial succession that starts with cocci such as Leuconostoc mesenteroides. These microbes begin fermentation by...
01:22Probiotics
Probiotics are live, non-pathogenic microorganisms that confer health benefits by modulating the gut microbiota. The human gastrointestinal tract harbors a complex microbial ecosystem, and the balance of this microbiota is crucial for digestive and systemic health. Among the most extensively studied and utilized probiotics are species formerly classified within the genera Lactobacillus and Bifidobacterium. These organisms not only naturally colonize the human gut but are also consumed through...
