Pr. Mamoudou H. DICKO, PhD

Thirty samples of sorghum beers “dolo” were selected from traditionally fermented household manufacturers from Burkina Faso. Dolo samples were screened for their total phenolic content, proanthocyanidins and putative antioxidant capacities, and were compared with industrial beers and wines. Total phenols were measured using the Folin-Ciocalteu method. Proanthocyanidins content were determined by the method of HCl-butanol hydrolysis. Antioxidant activities were evaluated both with 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay and by the trolox equivalent antioxidant capacity (TEAC) using 2,2’-azinobis(3-ethyl-benzothiazoline-6-sulfonic acid radical) (ABTS•+). The average contents of total phenols and proanthocyanidins were 506 μg GAE/ml of dolo and 45 μg ...

Micronesia: Steps In The Right Direction, Aydin Nazmi

Aydin Nazmi

As I watch the hazy orange sun sink into the still blue sea overlooking Chuuk lagoon, I marked the end of another seemingly ordinary day in the Federated States of Micronesia. But this October day was special—it marked the beginning of a promising new era in Chuuk’s fight against HIV and AIDS. For the past few months, several proceedings had set into motion a cascade of events that would ultimately (hopefully) benefit and educate the people of Chuuk state.

Fractionation Of Distillers Dried Grains With Solubles (Ddgs) Through A Narrowing Of Particle Size Distribution Followed By Aspiration, Rafael A. Garcia, Kurt A. Rosentrater

Kurt A. Rosentrater

Distiller's dried grains with solubles (DDGS) may have more value and utility if they can be separated into high protein and high fiber fractions. A variety of such separation processes have been proposed; two of the most promising processes involve three screening and three air classification unit operations. In the present study, an alternative process involving fewer unit operations is demonstrated. DDGS are subjected to a single screening, and the oversize particles are processed in a mill setup so that it narrows the particle size distribution of the oversize fraction. The milled DDGS is then processed in an air ...

How Much Serving Size Affects Consumption : Catch-22, Natalina Zlatevska, Chris Dubelaar, Stephen S. Holden Jan 2012

How Much Serving Size Affects Consumption : Catch-22, Natalina Zlatevska, Chris Dubelaar, Stephen S. Holden

Stephen S Holden

The effect of serving-size on consumption is well-established: the larger the serve, the greater the amount consumed. But what is the size of the effect, what are the processes driving the effect, and what are the conditions that facilitate vs. inhibit the effect? The present research uses a meta-analysis of 67 studies to quantify the effect of serving-size on amount consumed and to test two competing explanations of why the effect occurs. One view is that the serving-size is mediated by a perceptual effect, the other that it is mediated by a consumption norm. The meta analysis demonstrates that when ...
