概括
这项研究评估了奶酪中阿弗拉托辛M1 (AFM1) 的丰富系数 (EF). 目前的EF可能高估了AFM1污染风险,这表明需要修订法规,以更好地保护消费者免受这种致癌物质的影响.
科学领域:
- 食品科学 食品科学 食品科学
- 菌类毒理学 菌类毒理学
- 乳制品科学 乳制品科学
背景情况:
- 非洲毒素M1 (AFM1) 是一种在牛奶和乳制品中发现的致癌性菌毒素.
- 欧盟法规 1881/2006 规定了牛奶中的 AFM1 极限值,并强调了奶酪丰富因子 (EF) 的必要性.
- 意大利卫生部在2019年为牛乳制品提出了基于MFFB的EF.
研究的目的:
- 在无脂肪基础上 (MMFB) 测定不同水分含量的乳酪富化因子 (EFs) 对于阿弗拉托辛M1 (AFM1).
- 通过实验获得的EF与意大利卫生部提出的EF进行比较.
主要方法:
- 奶酪制造使用天然被各种AFM1度污染的牛奶.
- 分析牛奶和产生的奶酪中的AFM1含量,以计算EFs.
- 根据无脂肪基础上的水分含量对奶酪的分类 (MMFB).
主要成果:
- 经过实验确定的奶酪平均 EF 值始终低于意大利卫生部提出的值.
- 观察到EF的显著变化,可能与MMFB有关.
结论:
- 目前奶酪中AFM1的丰富系数 (EF) 可能被高估了.
- 为了准确的风险评估和消费者保护,建议重新考虑现有的EF.
- 需要进一步的研究来完善基于MMFB的EFs用于奶酪中的AFM1.

01:29Microbes in Food Production
Microbial fermentation is central to food biotechnology, enhancing flavor, texture, preservation, and stability. Fermentative microorganisms metabolize carbohydrates into organic acids, alcohols, and other metabolites that inhibit spoilage organisms and improve digestibility while contributing distinctive sensory qualities.In baking, amylases naturally present in flour hydrolyze starch into monosaccharides such as glucose, which Saccharomyces cerevisiae ferments anaerobically. Through...
01:25Clinical Significance of Antibiotic Resistance
Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within the One...
