Food Insecurity: Rudimentary Education For Local Youth (Firefly), Nam-Anh Nguyen, Quynh P. Nguyen, Jane E. Krause
Food Insecurity: Rudimentary Education For Local Youth (Firefly), Nam-Anh Nguyen, Quynh P. Nguyen, Jane E. Krause
Purdue Journal of Service-Learning and International Engagement
As service-learning becomes recognized as a significant teaching-learning tool for college students, the authors of this article came together to apply for the Purdue University Service-Learning Sustainability Projects Grant. Upon receiving the grant, with the encouragement of Professor Jane Krause and Food Finders Food Bank, the student authors created a project focused on food insecurity education in West Lafayette, Indiana. The main objective was to develop and teach a series of lessons on food insecurity and sustainability to middle school students using interactive activities. A team of Purdue students from various backgrounds was recruited to assist in planning and to …

Water Supply In Developing Countries: Student Experiences In The Dominican Republic, Albert Alwang, Margaret Busse, Audrey Caprio, Marieke Fenton, Jason Hawes, Andrew Kanach, Autumn Mcelfresh-Sutton
Purdue Journal of Service-Learning and International Engagement
In 2010, the United Nations established access to safe drinking water as a basic human right; however, many areas around the globe still lack access. The interdisciplinary service-learning course “Water Supply in Developing Countries” was established at Purdue in 2012 to address the complex issue of water insecurity around the world. Over the past five years, the course has produced teams involving students from nursing, engineering, agricultural economics, biology, and food science working together to develop sustainable, community-scale drinking water treatment systems. In partnership with Aqua Clara International, the student team in 2017 established a drinking water treatment system at …
Effect Of Particle Interactions On Powder Flow Behavior, Ivana A. Penagos, Carolina P. Mora, Teresa Carvajal
Effect Of Particle Interactions On Powder Flow Behavior, Ivana A. Penagos, Carolina P. Mora, Teresa Carvajal
The Summer Undergraduate Research Fellowship (SURF) Symposium
The study of powder flow behavior is essential for the development of processing technologies in many industries. In fact, powders have a major function in diverse types of manufacturing, such as pharmaceuticals, foods, chemicals, materials, minerals and cosmetics. This leads to an increasing demand for the development of reliable methods to assess powder flow problems in industry. This research intends to provide a general insight into how surface interactions and particle properties may alter powder flowability. The materials used for this study were lactose, starch, milk powder, cocoa and chocolate. These vary in their interparticle forces as well as on …
Investigation Of Low Cost Solar Drying Of Apricots For Tajikistan, Huimin Wang, Richard L. Stroshine Dr.
Investigation Of Low Cost Solar Drying Of Apricots For Tajikistan, Huimin Wang, Richard L. Stroshine Dr.
The Summer Undergraduate Research Fellowship (SURF) Symposium
Dried apricots are one of Tajikistan’s major export products. The country wants to expand its production in the southern region. However, the producers don’t have the expertise needed to produce dried apricots that meet the quality requirements of the European Union and other potential export markets. Local producers in southern Tajikistan would benefit from improvements in methods of applying sulfur and drying the apricots. This would allow them to gain a share of global markets. Methods that were studied include sulfur treatment prior to drying and approaches for rapidly drying the apricots while preventing contamination. Because the project has just …

Milk powders are becoming more ubiquitous within the food industry, and they offer consumers a convenient form for direct intake of dairy. The costs associated with dairy are reduced when products are converted to powder, which markedly increases shelf life at ambient temperatures. Creating compacts from powders further improves cost efficiency by reducing volume. However, milk powders typically possess poor rehydration properties, such as a slow dispersion rate and low solubility, and powder compaction additionally prolongs rehydration time, reducing consumer acceptability. Previous studies have shown that modifying dairy products before or during the drying process can improve rehydration properties, but …
Analysis Of The Flow Behaviors Of Corn Meal During Extrusion, Daniel N. Hauersperger, Martin R. Okos, Troy Tonner
Analysis Of The Flow Behaviors Of Corn Meal During Extrusion, Daniel N. Hauersperger, Martin R. Okos, Troy Tonner
The Summer Undergraduate Research Fellowship (SURF) Symposium
Food extrusion can be used to make many products we consume today, including pasta, cereals and more. The ability to predict the characteristics of the final product from an extruder using raw material characteristics and operating conditions is vital to the extrusion process. In order to answer this need, the flow behavior of corn meal was measured in a lab viscometer (off-line) and compared to the flow behaviors from an extruder (in-line) at three different moisture contents (32.5%, 35%, 37.5% wet basis). The extruder and product are heated through the friction of the corn meal passing through the barrel not …
Dataset Of Water Activity Measurements Of Alcohol: Water Solutions Using A Tunable Diode Laser, Matthew Allan, Lisa Mauer
Dataset Of Water Activity Measurements Of Alcohol: Water Solutions Using A Tunable Diode Laser, Matthew Allan, Lisa Mauer
Department of Food Science Faculty Publications
The data presented in this article are related to the research article entitled “RH-temperature phase diagrams of hydrate forming deliquescent crystalline ingredients” (Allan and Mauer, 2017) [1]. The data are water activity measurements of alcohol:water solu- tions (methanol:water and ethanol:water solutions at varying molar ratios) at different temperatures collected using the Tunable Diode Laser by Decagon Devices. The measured water activities of ethanol:water solutions were correlated to the initial volumetric ratios to produce polynomial equations that can be used to cal- culate the needed initial volumetric ratios for water activity con- trolled solutions. The data sets and polynomial equations are …
