Coffee Powder Wettability, Flowability And Characterization Thereof, Natalia Atuesta, Afolawemi Afolabi, Teresa M. Carvajal
The Summer Undergraduate Research Fellowship (SURF) Symposium
The production efficiency and high-quality results in industrial processes usually rely on how well product characteristics are understood as well as how well processes are controlled in order to obtain specific results. Therefore, in a billion-dollar industry as is the case of the instant coffee market, understanding the properties of the compounds produced using different techniques is a very important tool to enhance performance and delivery of high-quality coffee powders. The aim of the present study is to provide a framework of some powder properties such as particle size, shape, diameter, circularity, convexity, aspect ratio and surface energy among others, …
Compositional Analysis Of Carbohydrates Of A Family Of Legumes, Arvind Raghothama, Bruce Hamaker
Compositional Analysis Of Carbohydrates Of A Family Of Legumes, Arvind Raghothama, Bruce Hamaker
The Summer Undergraduate Research Fellowship (SURF) Symposium
Legumes, most commonly identified as beans or lentils, provide a good source of both protein and carbohydrates. Many legumes contain the polysaccharide arabinogalactans, classified as dietary fiber and have unique functional properties in foods. However, these, and other plant polysaccharides have not been well characterized. A preliminary collaborative study between Florida State University and the Whistler Center at Purdue indicated that isolated legume arabinogalactans appear to have high texturizing capability through formation of viscoelastic structures. Their soluble property may also present unique fiber nutritional trait. These properties of arabinogalactans and their variability among different legumes are yet to be analyzed. …
Investigation Of In-Package Ozonation: The Effectiveness Of Ozone To Inactive Salmonella Enteritidis On Raw, Shell Eggs, Austin Donner
Investigation Of In-Package Ozonation: The Effectiveness Of Ozone To Inactive Salmonella Enteritidis On Raw, Shell Eggs, Austin Donner
The Journal of Purdue Undergraduate Research
Food production, handling, and distribution practices pose a constant threat to the quality and safety of food products. The objective of this research is to evaluate an innovative in-package ozonation process to reduce Salmonella enteritidis on raw, shell eggs. Previous research has shown that in-package ozonation eliminates contaminants from outside sources, reduces pathogens, and extends shelf life. In this study, raw, shell eggs were inoculated with Salmonella enteritidis and exposed to ozonation treatment. Microbial recoveries were then tested to determine bacterial reductions. Measurements included: relative humidity (34 percent at 5oC), surface temperatures (oC), ozone concentrations, bacterial …
