Researchers found that sunflower seeds release a compound that may lower blood pressure, while moderate beer drinking reduces heart attack risk. Sauerkraut contains anti-cancer compounds, and onions help prevent bone loss. Meanwhile, regular hot dogs taste better than low-fat ones due to slower-releasing aroma compounds.
Researchers analyzed eight apple varieties and found Red Delicious and Northern Spy apples to have the highest antioxidant levels. Polyphenols in the skin and flesh of these apples were responsible for the highest antioxidant activity, with epicatechin and procyanidin B2 being key contributors.
Research reveals unique flavors and textures in Hispanic-style cheeses, while scientists also identify ways to make beans healthier and analyze the chemistry of margaritas. The study could lead to improved quality and marketability of these foods as they gain popularity in mainstream cuisine.
McGill researchers identified a link between heat-induced breakdown of amino acids and sugars in food, producing the potential carcinogen furan. Traces of furan have been found in processed and cooked products, particularly canned and bottled foods, but quantities are below considered dangerous thresholds.
New studies examine acrylamide levels in foods such as potato chips, breads and cereals. Researchers have found that cooking conditions influence acrylamide levels, with some foods showing low levels despite popular assumption.
Recent research findings highlight the health benefits of traditional Thanksgiving dishes such as cranberries, which can aid recovery from stroke, and may protect brain cells. Antioxidant-rich foods like hot cocoa tops both red wine and tea in cancer-fighting compounds.
Consuming foods containing trans fatty acids raises LDL cholesterol and the risk of coronary heart disease. Manufacturers can create these unhealthy fats by hydrogenating unsaturated oils, making them artery-cloggers.
Pediatric food allergies affect 6-8% of infants/children, primarily milk. Diagnosis involves a complete work-up, including history, physical, laboratory evaluation, and biopsy. Treatment includes elimination diets, oral challenge testing, and treatment for severe reactions.
Vandenberg discovered isotactic polypropylene, a strong and resistant form of polypropylene used in dishwasher-safe containers and water-resistant outdoor carpets. He has since developed new biomedical polymers with potential applications in implants and medical devices.
Cornell University professor Bruce Ganem proposes an alternative chemical pathway for acrylamide formation in fried or baked foods. He suggests that enzymatic decarboxylation of asparagine is the key step in this process, leading to the loss of carbon dioxide and the formation of acrylamide.
The DuPont team developed the BAX system, which detects harmful bacteria like E. coli and Salmonella in just five hours, reducing reporting time by one to two days.
Researchers at Stockholm University found high levels of acrylamide in fried, oven-baked, and deep-fried potato products. Cooking at higher temperatures increases acrylamide formation, while boiling is considered the safest method.
A new compound has been developed that offers intense cooling properties without the taste or smell of mint. The compound is 35 times more powerful than mint and lasts twice as long, making it ideal for a range of consumer products.
DuPont has donated $100,000 to the ACS Scholars Program, supporting 10 minority students pursuing college-level study in chemistry and chemical engineering. The program aims to develop minority scientists and engineers to address demographic predictions of a workforce shortage.
Researchers found that store-bought tofu, soy cheese, and soy drinks contain significant levels of oxalate, which can bind with calcium in the kidneys to form kidney stones. The American Dietetic Association recommends limiting oxalate intake to 10 milligrams per serving for patients with a history of kidney stones.
Researchers found that wasabi's isothiocyanates can inhibit the growth of Streptococcus mutans bacteria, which cause dental caries. This effect comes from wasabi's ability to interfere with sucrose-dependent cell adherence. Wasabi has been implicated in various health benefits due to its antimicrobial properties.
Chlordane, a persistent organic pollutant, accumulates in the human body and can cause digestive and nervous system disorders; washing food before eating can reduce exposure risk
Historian Alan J. Rocke presents a symposium on the history of futurism in chemistry, exploring divergent visions of science in the year 2000. The event highlights the accuracy of 19th-century predictions about the 20th century and showcases the evolution of chemistry.
The American Chemical Society's 219th national meeting in San Francisco will explore cutting-edge chemistry research, including new prospects for anticancer agents and the environmental impact of MTBE. The conference also addresses food safety and nutrition, as well as substances of abuse.
The American Chemical Society's March 26-30 meeting in San Francisco will feature presentations on emerging trends in chemistry, including anticancer therapies, endocrine disruptors, and new drug delivery techniques. More than 6,000 papers are expected to be presented to the 14,000 attendees.
