Impact of the reduction or replacement of NaCl during production and ripening of raw cured pork and turkey sausages

• Sun, 07/21/2024 - 04:00
• European Food Research and Technology

• There are health concerns with regard to the consumption of sodium. Excessive consumption of sodium is suspected to cause high blood pressure, among other things. Therefore, sodium should be reduced or replaced during the production of food. In the present study, in the first part, raw fermented sausages from pork and turkey meat, produced with reduced NaCl concentrations, were investigated.

Relationship between Salmonella enterica attachment and leaf hydrophobicity, roughness, and epicuticular waxes: a focus on 30 baby‐leaf salads

• Sun, 07/21/2024 - 04:00
• Journal of the Science of Food and Agriculture

• Abstract BACKGROUND The first step in the contamination of leafy vegetables by human pathogens is their attachment to the leaf surface. The success of this is influenced strongly by the physical and chemical characteristics of the surface itself (number and size of stomata, presence of trichomes and veins, epicuticular waxes, hydrophobicity, etc.).

Time Trends in Causes of Death in People With HIV: Insights From the Swiss HIV Cohort Study

• Sat, 07/20/2024 - 04:00
• Clinical Infectious Diseases

• Background Advancements in access to antiretroviral therapy (ART) and human immunodeficiency virus (HIV) care have led to a decline in AIDS-related deaths among people with HIV (PWH) in Switzerland. However, data on the ongoing changes in causes of death among PWH over the past 15 years are scarce. Methods We investigated all reported deaths in the Swiss HIV Cohort Study between 2005 and 2022.

Volatile profiles of Murcott and Ponkan mandarins obtained by stir bar sorptive extraction technique and their contributions to the fruit aroma

• Sat, 07/20/2024 - 04:00
• Journal of Food Science

• Abstract Citrus species have undergone immense diversification ever since their ancestral origin. Ponkan and Murcott are two mandarin varieties widely consumed in Brazil and their aroma producing active compounds have not yet been extensively investigated. The present study analyzed the volatile constituents of the Ponkan and Murcott varieties employing the stir bar sorptive extraction (SBSE) technique and gas chromatography‐mass spectrometry (GC‐MS) analysis for the first time.

• Mycotoxin Research

• Yogurt, a milk-derived product, is susceptible to mycotoxin contamination. While various methods have been developed for the analysis of dairy products, only a few have been specifically validated for yogurt. In addition, these methods are primarily focus on detecting aflatoxins and zearalenone. This study aimed to conduct a preliminary investigation into the presence of regulated, emerging, and modified mycotoxins in natural and oat yogurts available in the Spanish market.

Droplet digital PCR and real-time PCR for the sensitive and specific detection of Vibrio vulnificus based on the novel target genes

• Fri, 07/19/2024 - 04:00
• European Food Research and Technology

• Vibrio vulnificus poses a significant risk to public health due to its high pathogenicity and mortality rates as a common seafood-borne pathogen. Therefore, rapid, accurate, and specific detection methods for V. vulnificus are crucial for ensuring human safety and minimizing economic losses. This study identified vvhA and vv08030 as promising targets for V. vulnificus detection using bioinformatics screening and PCR analysis.
