2014 AOCS Annual Meeting & Expo
From the challenges that were addressed to the ideas and technologies that were presented, the 2014 AOCS Annual Meeting & Expo in San Antonio (May 4–7) was proof positive that everything is bigger in Texas.

Advances in biodiesel production
This issue of Inform features two advances in biodiesel technology—one based on a liquid lipase and the other on solid catalysts.

Using enzymes to make biodiesel from low-quality oils
A new lipase technology makes it possible to produce biodiesel from oils widely varying in quality—regardless of their free fatty acid content. Compared to a standard chemical catalyst, the liquid lipase is much cheaper to produce and provides technological as well as cost benefits. It has already been used in full-scale production, and the enzymatic biodiesel application is expected to be commercially available later this year.

Innovative catalysts open new opportunities in biodiesel market
Solid catalysts offer several economic advantages. They last for several years, enable continuous production at commercial scale without reference to periodic changes of feedstock or feedstock blends, and enable blending of feedstocks to achieve optimal cold-flow properties in the final product at a low raw material cost.

Replacing trans fats
What will it take to completely eliminate partially hydrogenated oils from manufactured foods? Read what food scientists, industry representatives, regulators, and public education groups have to say about the practical implications of eliminating PHOs from manufactured foods.

Innovative technologies for trans-fat reduction in shortening and oils
Over the past decade, the food industry has decreased the use of partially hydrogenated oils—which contain unhealthful trans-fats—by about 75%. This article reviews some of the innovative technologies that made this substantial reduction possible.

Modification of gold nanoparticles for SERS analysis of edible oils
Raman scattering is commonly used to identify explosives and to identify and validate ingredients in the pharmaceutical industry. Food scientists recently used gold nanoparticles in conjunction with a new technique called surface-enhanced Raman spectroscopy (SERS) to determine the occurrence of oxidation in canola oil more quickly than with traditional tests.

A beginner’s guide to enzymes in detergents
Learn about the major classes of enzymes and how they’re used in detergents, trends driving enzyme use in detergents and current trends for enzymes within detergents, and the challenges of using enzymes in detergents and enzyme stabilization technology.

Natural fats and oils in cosmetics
Oils and fats can prevent the loss of the skin’s lipid components and even replenish them. A researcher for Johnson & Johnson reviews the use of various oils, fats, and waxes in modern cosmetics.
