Detecting specific strains of bacteria that cause food poisoning quickly is important to food safety. Current methods can be either time-consuming or expensive. Now, a team of electrical engineers from the United States and Turkey have developed a fast and inexpensive technology to detect and identify specific strains of bacteria like E. coli. Their study […]
Expertos de la UNAM desarrollaron proteínas para frenar el crecimiento de la bacteria patógena Listeria monocytogenes, que puede estar presente en áreas donde se procesan alimentos y transmitirse a los humanos a través de productos lácteos, pescados, embutidos y vegetales contaminados. Esta bacteria es causante de listeriosis, enfermedad que afecta a grupos de alto riesgo […]
Los quelites tienen un importante aporte nutrimental: son ricos en micronutrientes, fibra, minerales y vitaminas; son económicos y, además, tienen potencial en el tratamiento contra la gastritis, reveló un estudio de la UNAM. Científicos encabezados por Irma Romero Álvarez, del Departamento de Bioquímica de la Facultad de Medicina (FM), descubrieron en laboratorio que esta planta […]
Prebiotics (fermentable fibers) and probiotics (beneficial microbes) are key to establishing a healthy gut microbiome. While most dietary prebiotics can successfully traverse the digestive system, most dietary probiotics cannot survive digestion. Scientists at the Chinese Academy of Agricultural Sciences have developed a gel to help probiotics reach their destination: the colon. Probiotics are live microorganisms […]
Investigadores de la UNR estudian el uso de virus bacteriófagos para prevenir el desarrollo de la bacteria Escherichia coli en los alimentos. Escherichia coli es la bacteria responsable de producir enfermedades como la diarrea o el Síndrome Urémico Hemolítico, que es el principal responsable de la insuficiencia renal aguda pediátrica ya que afecta principalmente a […]
Researchers at the University of Toronto have come up with what appears to be an easy and cost-effective approach to reducing the threat of microbial pathogen contamination on food processing equipment: coating it with a thin layer of cooking oil. Scientists in the university’s Dept. of Materials Science and Engineering, working with a food scientist […]
Vitamin K is a fat soluble vitamin commonly found notably in leafy green vegetables, grass-fed cheese and butter. Widely known for playing an integral role in the blood clotting process, more recent research now suggests that vitamin K may also have a critical role in bone health. Studies suggest that this nutrient plays an integral […]
“Research shows [migraine] sufferers have higher levels of bacteria involved in processing nitrates, and could explain why some foods appear to act as migraine triggers,” The Guardian reports. Nitrates are found in processed meats, like bacon, as well as some wines and chocolate. The story is based on a study that used data from the […]
