Chocolate can be fruity or flowery, if you skip the roasting step
"Natural" foods are trendy, and proponents claim that little or no processing helps preserve the food's inherent flavor. Research now published in the Journal of Agricultural and Food Chemistry shows that, at least for certain artisanal, bean-to-bar.....»»
DNA barcoding identifies the plants a person has eaten
What people say they've eaten and what they've actually eaten are often two very different lists of foods. But a new technique using DNA barcoding to identify the plant matter in human feces may get at the truth, improving clinical trials, nutrition.....»»

Testing antimicrobial resistance in non-typhoidal Salmonella from retail foods collected in 2020 in China
Non-typhoidal Salmonella (NTS) is a major cause of human salmonellosis globally. Food animals are major NTS reservoirs. An increase in antimicrobial resistance (AMR) in foodborne NTS has led to clinical treatment failures. To examine the prevalence a.....»»
Breaking barriers: Advancements in meta-holographic display enable ultraviolet domain holograms
The term meta means a concept of transcendence or surpassing, and when applied to materials, metamaterials encompass artificially engineered substances that exhibit properties not naturally found in the environment. Metasurfaces, characterized by the.....»»
Study in mice links heat-damaged DNA in food to possible genetic risks
Researchers have newly discovered a surprising and potentially significant reason why eating foods frequently cooked at high temperatures, such as red meat and deep-fried fare, elevates cancer risk. The alleged culprit: DNA within the food that's bee.....»»
