Structure-Function Guided Extraction and Scale-Up of Pea Protein Isolate Production.

The lack of adequate guidance and control of the extraction conditions as well as the gap between bench- and industrial-scale production, contributes to the poor functionality of commercial pea protein isolate (cPPI). Therefore, pea protein extraction conditions were evaluated and scaled up to maximize protein purity and yield, while maintaining structural integrity, following mild alkaline solubilization with isoelectric precipitation and salt solubilization coupled with membrane filtration. Both extraction methods resulted in high protein yield (>64%) and purity (>87%).

Adolescent health literacy: the importance of credible sources for online health information.

Background: Little research has examined adolescent health literacy and its relationship with online health information sources. The purpose of this study is to explore health literacy among a predominantly Hispanic adolescent population and to investigate whether exposure to a credible source of online health information, MedlinePlus(®), is associated with higher levels of health literacy.

Methods: An online survey was administered to a cross-sectional random sample of high school students in South Texas.
