概括
橄厂的多提取物对具有高细菌负载的狩猎肉具有有限的有效性. 然而,它们在初始负载较低的游戏肉上显著减少了细菌,只要保持良好的卫生条件.
科学领域:
- 食品科学 食品科学 食品科学
- 微生物学 微生物学
- 自然产品 化学 化学
背景情况:
- 橄厂的植被水是多醇的丰富来源,如氧和醇.
- 聚醇具有抗微生物特性,在食品保存中具有潜在的应用.
- 游戏肉容易受到微生物污染,需要有效的保存策略.
研究的目的:
- 评估橄厂聚烯提取物在减少猎物肉表面微生物群的有效性.
- 为了比较不同聚烯配方和度对细菌负载的影响.
- 评估初始细菌负载对多治疗的抗菌疗效的影响.
主要方法:
- 具有高 (>5 Log cfu/g) 和低 (<5 Log cfu/g) 初始细菌负载的猎物肉被处理为10%和25%的微封装和非封装多提取物的溶液.
- 治疗包括浸泡或浸泡10秒或60秒.
- 细菌数量 (有氧菌群,Enterobacteriaceae,Pseudomonas spp.,乳酸细菌) 在+3°C的真空储存7天后被确定.
主要成果:
- 只有在高细菌负载的肉类上使用10%液体提取物时,才能观察到有氧殖民地数量的显著减少 (0.64日志).
- 对于初始细菌负载较低的野生动物肉,10%的多溶液在7天和14天后显著降低了所有测试细菌的数量 (p < 0.002).
- 对低负荷肉的治疗疗效独立于应用方法 (浸泡与浸泡).
结论:
- 橄厂的多提取物在降低初始微生物负载较低的狩猎肉的细菌污染方面更有效.
- 这些提取物作为食品安全措施的应用取决于在肉类加工过程中保持高卫生标准.
- 进一步的研究可能会探索优化配方或协同组合,以提高高负载肉制品的有效性.

Surface Membrane Barriers

The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

Hand hygiene

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.
