Factors Affecting Folic Acid Stability In Micronutrient Fortified Corn Tortillas, Jordan S. Chapman Jul 2009

Factors Affecting Folic Acid Stability In Micronutrient Fortified Corn Tortillas, Jordan S. Chapman

Theses and Dissertations

Folate degradation in micronutrient fortified corn masa and tortillas was evaluated using masa prepared from either nixtamalized corn flour or fresh nixtamal. A laboratory evaluation of the effects of pH, iron, and holding time at elevated temperature on folate loss in corn flour masa failed to show significant differences in any variable-treatment combination. An additional study was conducted at a commercial tortilla mill in Guadalajara, Mexico using masa prepared from fresh nixtamal. Commercial nixtamal was fortified with one of two different micronutrient premixes, containing iron, zinc, riboflavin, thiamin, niacin and either unencapsulated or lipid-encapsulated folic acid. A batch of each ...

Preparation, Separation, Purification, Characterization And Human Cell Line Anti-Cancer Evaluation Of Rice Bran Peptides, Arvind Kannan

Theses and Dissertations

Bioactive compounds are revolutionizing the nutritional and medicinal world with their inherent disease-fighting properties. A wide range of functional groups fall under the category of imparting health benefits. Compounds from both animal and plant origins have been generated as bioactive agents that have opened up new vistas for alternative medicine and natural healing. For example, in a debilitating disease like cancer, these compounds can act to suppress or delay the underlying pathology over and above the conventional treatment strategies involving drugs or chemotherapy. In other words conventional and invasive therapy, although still considered appropriate at certain stages of cancer, their ...
