Food Science Faculty Publications and Presentations

Chickpea proteins offer significant nutritional and functional benefits in food products; however, their utilization is often restricted by off-flavors, primarily for lipoxygenase (LOX) and lipase activity. This study aims to develop a novel extraction method by combining acid (pH 2.0) extraction with the conventional alkali (pH 9.0) method to inactivate enzymes and enhance protein quality. Acid-extracted proteins exhibit the highest purity (83.4%), albumin content, and structural flexibility (46.65% random coil). Both acid and sequential acid-alkali-extracted proteins significantly reduced LOX (0.75 and 0.88 U/g) and lipase (0.10 and 0.08 U/g) activity. Acid extraction significantly lowers volatile compounds such as hexanal (0.0409 …

Developing Four-In-One Genetic Engineering System To Improve Production Of Bioenergy In Sorghum, Oluchukwu Jecinta Onyemaobi

Tennessee State University Alumni Theses and Dissertations

Sorghum (Sorghum bicolor L.) is a C4 crop of significant agricultural and industrial importance, known for its high biomass yield, drought tolerance, and adaptability to marginal lands. However, the high lignocellulosic biomass content of sorghum, particularly its lignin component, poses a significant challenge for efficient biomass conversion. Genetic engineering offers a powerful approach to achieve such improvements by targeting the modification of lignin biosynthetic pathways. However, progress in sorghum genetic improvement has been hindered by the crop’s recalcitrance to genetic manipulation, transformation, and regeneration. To overcome these limitations, we developed a four-in-one genetic engineering technology for sorghum by establishing an …

Guest Editors’ Introduction, Maurits Bastiaan Meerwijk, Nicolo Paolo P. Ludovice

Philippine Studies: Historical and Ethnographic Viewpoints

This introduction examines the historical evolution of health messaging in the Philippines, tracing its roots from early twentieth-century colonial public health campaigns to contemporary pandemic responses. It argues that health messaging, initially termed “medical propaganda,” has consistently served as a tool for persuasion and governance, intertwining communication, politics, and medicine. The introduction highlights how visual technologies and simplified narratives have been used to normalize biomedical authority, often obscuring complex realities. It concludes by emphasizing the need for a broader epistemic repertoire to navigate health knowledge in an era of misinformation.
