Microflora Of Traditional Mexican Corn Masa And Its Effect On Folic Acid Degradation, Stephen J. Adolphson Dec 2012

Microflora Of Traditional Mexican Corn Masa And Its Effect On Folic Acid Degradation, Stephen J. Adolphson

Theses and Dissertations

Many Mexican women consume inadequate amounts of folic acid. Fortification of the corn tortilla could be an effective way to help increase the folic acid levels among the Mexican population. Previous studies have shown significant folic acid losses in fortified tortilla dough (masa) as it is held before baking. This loss in folic acid could be due to degradation by lactic acid bacteria naturally present in the masa. The microflora of traditionally made nixtamalized corn masa from six tortilla mills in Guadalajara, Mexico were isolated and characterized, and their effect on folic acid content was evaluated. Isolated bacteria were identified ...


Superweeds And Suspect Seeds: Does The Genetically-Engineered Crop Deregulation Process Put American Agriculture At Risk, Margaret Sova Mccabe Jan 2012

Superweeds And Suspect Seeds: Does The Genetically-Engineered Crop Deregulation Process Put American Agriculture At Risk, Margaret Sova Mccabe

Law Faculty Scholarship

The federal government’s regulatory approach to genetically engineered (GE) crops, known as “The Framework”, is now twenty-five years old. Despite two and half decades of a consistent regulatory regime, GE crop and food regulation remains controversial. This article suggests that regulatory science and its tenets of independence, transparency, and public science should guide reforms of The Framework so that it is an efficient and reliable regulatory system. The article has four parts: 1) it provides a brief overview of the history of GE crop regulation; 2)it describes the key attributes of The Framework and related regulatory documents, with ...


Characterization Of Normal And Waxy Corn Starch For Bioethanol Production, Hanyu Yangcheng Jan 2012

Characterization Of Normal And Waxy Corn Starch For Bioethanol Production, Hanyu Yangcheng

Graduate Theses and Dissertations

The uncertainty of future oil supply and growing concerns of the energy security of the United States have boosted the investment in alternative energy carriers, including biofuels. Bioethanol, made from bio-renewable resources, has gained the mainstream usage in the USA. Ethanol is almost exclusively made from corn in the USA. The objectives of the study were: 1) To compare the differences of ethanol production between the normal and waxy corn using a cold-fermentation process; 2) To understand the effects of starch structure and properties on the ethanol production. Ethanol yields of the waxy corn ranged from 33.1% (33.1g ...
