Microbiota Modulation by Antibiotics

Microbiota Modulation by Antibiotics

Antibiotics have revolutionized modern medicine by saving countless lives from bacterial infections. However, their widespread use has inadvertently harmed the delicate balance of the human gut microbiota. The gut microbiota, a complex community of bacteria, archaea, viruses, and fungi, plays a vital role in regulating metabolism, immune responses, and maintaining intestinal health. Antibiotics, especially broad-spectrum types, disrupt this ecosystem by eradicating both harmful and beneficial...

背景情况:

牛奶中的阿弗拉托克辛M1 (AFM1) 构成了全球公共卫生风险和乳制品行业的经济挑战.
控制牛奶中AFM1污染的有效方法对于消费者安全和市场完整至关重要.

研究的目的:

评估纳米基托桑和粘土托尼特在降低UHT牛奶中AFM1水平方面的有效性.
评估这些药物对UHT牛奶的感觉属性和成分属性的影响.

主要方法:

在UHT牛奶中添加了AFM1并用不同度 (0.25%,0.5%,1.0%) 的纳米基托桑和本托尼特处理.
AFM1度,感官属性 (味道,颜色,外观) 和牛奶成分 (蛋白质,脂肪,乳糖等) 进行了分析.

主要成果:

纳米基托桑将AFM1降低了64.5%至80.2%,而托尼特则降低了21.7%至38.6%.
没有观察到任何药物治疗的牛奶的感觉特性或主要组成参数的显著变化.
两种药物在不同度的AFM1降低中都显示出显著差异 (p<0.05).

结论:

纳米基托桑在从UHT牛奶中吸附AFM1方面非常有效,本托尼特显示中等效率.
这些解毒剂不会对牛奶的感觉特征或营养成分产生不利影响.
建议在自然污染的牛奶中进行进一步的体外验证,以确认实际适用性.
