Comparison Of Methods To Evaluate Chitosan As An Antimicrobial Against Listeria Spp. Cultures, Scott Hartley
Comparison Of Methods To Evaluate Chitosan As An Antimicrobial Against Listeria Spp. Cultures, Scott Hartley
All Theses
The antimicrobial properties of a chitosan-coated vacuum-packaged pouch were tested against Listeria monocytogenes (LM) inoculated on frankfurters. A 1.5% chitosan solution was successfully coated onto a corona-treated poly/nylon based film and then heat-sealed to form a pouch. An initial 5 log CFU/mL population of LM was used to inoculate a frankfurter in the pouch, which was then vacuum-sealed and stored at 4¡ and 13¡ C for a period of 8 weeks, with bacteria enumeration performed on weekly intervals. An uncoated pouch was tested as a control. It was found that the chitosan-coated pouches did not exhibit any antimicrobial properties against …
Effectiveness Of Display Trays On Attention And Purchase Of Consumer Products, Erin Snyder
Effectiveness Of Display Trays On Attention And Purchase Of Consumer Products, Erin Snyder
All Theses
Through the collection of qualitative and quantitative data, consumer perception and preference of display trays in the retail environment was examined and evaluated. Purchase decision and eye-tracking data was collected, as well as qualitative survey information, to determine if participants favored packages in a display tray opposed to packages placed directly on store shelving. This preference was measured in terms of time to first fixation, total fixation duration, fixation count as well as final purchasing decision. The experiment analyzed liquid dish soap and canned tomatoes, and was organized as a 2 (products per category) x 1 (display tray per category) …
The Effect Of Applying Established Color Theory To Packaging When Visible Product And External Labels Exist Simultaneously, Rachel Randall
The Effect Of Applying Established Color Theory To Packaging When Visible Product And External Labels Exist Simultaneously, Rachel Randall
All Theses
Color is affected by what is around it. A color doesn't necessarily look the same when its placed against two different colored backgrounds (Ryan, William, and Theodore Conover, 2004) Oftentimes, designers are given a blank package and given the task of creating a label or package for the product. What is missing is the product, which can be an integral part of this design process. What is not yet to be determined by current packaging research is how colors work together through the product and package. One way to determine this would be through transparent bottled packages that contain external …
The Effect Of Packaging Material Properties On Consumer Food Quality Perception In Quick-Service Restaurants, Emily Thackston
The Effect Of Packaging Material Properties On Consumer Food Quality Perception In Quick-Service Restaurants, Emily Thackston
All Theses
The majority of menu items available in quick-service restaurants (QSR) are consumed directly from a container or package. The main reasons consumers choose to eat fast food are because it is convenient, prepared quickly, a good value, and inexpensive. Therefore, the packaging becomes an integral part of the food product and from a consumer perspective must be consistent with their expectations and motives for choosing to eat fast food. Prior research has directly linked characteristics of consumer food packaging experience to their perception of its contents. The purpose of this research is to determine if consumer quality perception of food …
Measuring Arousal Through Physiological Responses To Packaging Designs: Investigating The Validity Of Electrodermal Activity As A Measure Of Arousal In A Realistic Shopping Environment, Daniel Hutcherson
All Theses
The validity of electrodermal activity is investigated in the context of packaging design evaluation as a sensitive measure of arousal. Analysts agree that purchasing decisions are subconscious and emotional decisions, contrasted against the popular belief that consumers make purely rational decisions. To understand the personal and rapid character of a consumer's purchasing decisions we must find methods of which to measure and interpret consumer reactions to various packaging designs. Focus groups are discussed as antiquated research methods and new, advanced technologies are outlined as physiological responses. Past literature displays methodological approaches to using electrodermal activity measures in consumer studies, however …
