The UK's Department of Health and Social Care has opened a public consultation on possible limits on how food and drink products high in fat, salt or sugar are promoted. Food and Drink Federation executive Tim Rycroft called the announcement "wrong-headed and muddled."
Researchers have found a correlation between unbalanced diets and premature cardiovascular disease death -- specifically diets low in seafood omega-3 polyunsaturated fatty acids, nuts and seeds, and whole grains but high in sodium. The international study, published in the European Journal of Epidemiology, analyzed data from more than 50 countries over a 26-year period, with attention paid particularly to 2010 through 2016.
A team of researchers from the University of California at San Diego has created a CRISPR-based precision-guided sterile insect technique for controlling targeted agricultural pests. The technique involves the simultaneous disruption of genes controlling male fertility and female viability, leading to 100% sterile male progeny, and the introduction of the eggs created using this technology into targeted populations.
Renewal Mill has developed a process that turns okara waste from soy products into a flour substitute, reducing the amount of unused byproduct. The Oakland, Calif. company also plans to use its technology to create useful products out of other food waste, such as potato pulp and pistachio shells.
JAOCS article of the month: understanding biodiesel production from waste cooking oils
Studies have shown that biodiesel yields from waste cooking oil (WCO) can be improved by using an acid-catalyst. Yet, a solid acid catalyst has not been widely applied in biodiesel production because reaction rates are slow and the reaction pathways of triacylglycerols on solid acids are unknown. In this month's JAOCS article of the month researchers from the University of Technology and the Chinese Academy of Sciences in Shanxi, China employ computational models to determine the mechanism of converting WCOs into biodiesel fuel through an acid-catalyzed transesterification reaction. In the paper titled, "A Density Functional Theory Study on the Acid-Catalyzed Transesterification Mechanism for Biodiesel Production from Waste Cooking Oils," corresponding authors Xiaochao Zhang and Caimei Fan report that a solid acid catalyst lowers the activation energy of the transesterification reaction and describe the pathways for how that reaction occurs.

#WebinarWednesday: The AOCS Path to a New Method
Known throughout the world as the most comprehensive collection of analytical testing methods for fats and oils, the Official Methods and Recommended Practices of the AOCS contains more than 450 methods. This webinar will describe the process by which new methods are incorporated into the AOCS methods catalog. Register here for the webinar, which will be held on January 30 at noon CST.
No art or learning is to be pursued halfheartedly ... and any art worth learning will certainly reward more or less generously the effort made to study it.
