Two examples include the way lipids in milk and nuts are modified as they traverse the gastrointestinal tract. What’s in a claim? Would a food not labeled “natural” taste as sweet? 142 Consumer fraud class actions aimed at food and beverage companies over natural claims are on the rise. How can such actions be avoided without the establishment of clear regulatory requirements for the claim? New biodiesel production easier and more economical Read how several companies are or will soon be using a new enzymatic process to 170 develop and distribute biodiesel fuels. 142 145 183 Achieving energy savings through smarter pumping technology Twenty-seven percent of the electricity consumed in an industrial system that requires 172 liquid handling is used to operate pumps. Learn how energy-saving pumps can cut those electricity costs. How to successfully manufacture a low-fat spread 174 with only 10% fat Instability problems and insecure production parameters can make low-fat spreads chal- lenging to produce. In this article, a product and applications manager from the Dan- ish emulsifier specialist Palsgaard A/S describes how his company created an emulsifier system for 10% low-fat spreads, stabilized the fat and water phases, and set up optimal processing and storage conditions. High throughput research for formulators Can the automated tools used to quickly assay the biological or biochemical activity of 183 a large number of drug-like compounds accelerate the research and development of new surfactant and detergent formulations? A technical leader at the Dow Chemical Company who has developed more than a dozen consumer products using such tools explains how high throughput research can be used to evaluate cleaning efficacy, soil suspension, wetting, filming and streaking, fragrance release, and other characteristics important to formulation performance.
