The European Food Safety Authority has concluded that emulsifier E471 is safe at reported levels, but it has recommended new limits to avoid contaminants from the vegetable oil refining process. These include revised maximum limits for trans fatty acids, glycidyl esters, impurities and residual solvents.
A team of scientists has produced a groundnut that is immune to aflatoxins by pairing two processes. The researchers used small proteins to block the formation of the fungus, as well as Host-Induced Gene Silencing, allowing groundnuts such as peanuts to use RNA molecules to stop the synthesis of aflatoxin.
MIT researchers have developed a technique for water-in-oil emulsification that is scalable and does not require mixing. They note that "the oil-surfactant concentration controls the spreading behavior of oil on water, as well as the peak size, polydispersity, and stability of the resulting emulsions."
Mexico will reply to US proposals including a sunset clause and changes to the content rules for automobiles as part of the fifth round of North American Free Trade Agreement talks beginning today.

Projects such as Sasol Chemicals' $11 billion ethane cracker and complex near Lake Charles, La., require collaboration from an array of industries, writes Meredith Whitten. The Kansas City Southern Railway, for example, is revamping its nearby rail yard to help transport feedstocks and materials for Sasol's project.
The 20th anniversary of America Recycles Day, a nationwide recycling initiative sponsored by the American Chemistry Council and other partners, is today. This year's theme is "Be Recycled."
Polymer manufacturers are increasing their production of materials for 3D printing. Lubrizol, Evonik Industries, BASF and Arkema are testing materials under HP's open materials and applications program, and Arkema has developed a new type of polyetherketoneketone as a substitute for metal parts.
