概括
过氧酸 (PAA) 有效地消毒蔬菜,如生菜和胡卜,减少有害细菌而不会影响味道. 这项研究表明,PAA对于食品安全而言,是一种比二 (SH) 更安全的替代品.
科学领域:
- 食品科学 食品科学 食品科学
- 微生物学 微生物学
- 食品安全 食品安全
背景情况:
- 新鲜蔬菜引起的食物传播疾病是一个重大的公共卫生问题.
- 二 (SH) 是一种常见的消毒剂,由于残留物和消毒副产品 (DBPs) 存在风险.
- 过氧酸 (PAA) 已获得批准,但其工业有效性和对蔬菜的风味影响需要系统评估.
研究的目的:
- 为了比较PAA和SH在生菜和红上对关键的食源病原体的杀菌效果.
- 用电子鼻子技术评估PAA对蔬菜风味的影响.
- 为了确定PAA的适用性作为工业消毒剂替代SH.
主要方法:
- 对PAA和SH对大肠杆菌,沙门氏菌, Typhimurium和 Staphylococcus aureus 的杀菌有效性进行测试.
- 使用电子鼻子技术进行风味特征分析.
- 评估PAA在pH范围 (3-9) 的性能.
主要成果:
- PAA (60-80 ppm) 显示出强大而快速的病原体减少,PAA的60 ppm降低了低于检测极限的生菜上的病原体.
- 在较低度下,PAA显示出优于SH的疗效;60ppm的PAA与200-300ppm的SH相当.
- 在80ppm的PAA下观察到风味变化,但在≤60ppm的度下可以忽略不计.
结论:
- PAA是一种高效的杀菌剂,可以对新鲜蔬菜上常见的食源性病原体产生高效的杀菌作用.
- PAA为SH提供了一个更安全的替代品,避免有害的DBPs,并在广泛的pH范围内保持有效性.
- PAA,特别是度 ≤60 ppm,为工业蔬菜消毒提供了可行的选择,对感觉影响最小.

Chemicals play important roles in controlling microbial growth by targeting microbial structures and functions as sanitizers, antiseptics, disinfectants, and sterilants.Alcohols are commonly used sanitizers, effectively disrupting lipid membranes, which compromises cell integrity. They are also used as antiseptics and disinfectants due to their rapid action and versatility.Phenols and their derivatives phenolics , known for denaturing proteins and disrupting cell membranes, are particularly...

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.

In healthcare, the chemical method of sterilization uses chemical sterilants to treat surgical instruments and medical supplies to help prevent the transmission of infectious pathogens to patients. Due to heat sensitivity, most medical supplies and equipment should not be exposed to high temperatures. These parts include rubber, plastic, glass, and other similar elements.
Using chemical sterilization rather than heat to clean out equipment is recommended. It eradicates and removes all bacteria,...

Acids are classified by the number of protons per molecule that they can give up in a reaction. Acids such as HCl, HNO3, and HCN that contain one ionizable hydrogen atom in each molecule are called monoprotic acids. Their reactions with water are:

Weak Acid Solutions
44.1K
Few compounds act as strong acids. A far greater number of compounds behave as weak acids and only partially react with water, leaving a large majority of dissolved molecules in their original form and generating a relatively small amount of hydronium ions. Weak acids are commonly encountered in nature, being the substances partly responsible for the tangy taste of citrus fruits, the stinging sensation of insect bites, and the unpleasant smells associated with body odor. A familiar example of a...
