Consumers are increasingly demanding the development of ready-to-eat gluten and lactose-free food products that meet their needs and help improve their health. A recent study in Journal of Food Science, published by the Institute of Food Technologists (IFT), shows how new white sauce formulations are being created to meet these demands. Consumers with celiac disease often find that gluten-free products are of inferior quality compared with their traditional, non-gluten-free counterparts. Traditional white sauce is made with milk, flour or starch, oil, and salt...

UC Irvine and Brown University researchers have created a new fruit fly model of inherited epilepsy that's providing insights into the mechanisms underlying temperature-dependent seizures while establishing a platform from which to develop therapies for these disorders. In The Journal of Neuroscience, Diane O'Dowd of UCI, Robert Reenan of Brown and colleagues report their method for placing a gene mutation that causes human fever-induced seizures into drosophila fruit flies. As a result, the mutant flies experience heat-induced seizures...

Leaves of the plant that yields carob - the substitute for chocolate that some consider healthier than chocolate - are a rich source of antibacterial substances ideal for fighting the microbe responsible for listeriosis, a serious form of food poisoning, according to a report in ACS' Journal of Agricultural and Food Chemistry. Nadhem Aissani and colleagues explain that the increase in antibiotic-resistant bacteria has fostered a search for new natural substances to preserve food and control disease-causing microbes...
