Exploring Attitudes And Reactions To Unfamiliar Food Pairings: An Examination Of The Underlying Motivations And The Impact Of Culinary Education, Mark Traynor, Andrew Moreo, Lisa Cain, Roisin Burke, Catherine Barry-Ryan

Articles

A mixed-methodology study was conducted to better understand consumer attitudes and behaviors toward novel food pairings and the impact of culinary education. Focus groups were conducted to investigate the underlying motivational factors to the reactions and behaviors toward unfamiliar foods. The second phase of the study consisted of sensory evaluation by two separate cohorts, panelists with and without culinary education, of food products created through the novel pairings of foods. Panelists with culinary education expressed a greater overall liking for the animal-based pairing. Sensory-Affective and Ideational factors appeared to be underlying motivational factors of these hedonic reactions.

Pcr Cloning Combined With Dna Barcoding Enables Partial Identification Of Fish Species In A Mixed-Species Product, Anthony J. Silva, Michael D. Kawalek, Donna M. Williams-Hill, Rosalee S. Hellberg

Food Science Faculty Articles and Research

DNA barcoding is a valuable tool for regulatory identification of fish species; however, it does not perform well when multiple species are present within the same food product. Therefore, the objective of this study was to examine the use of PCR cloning to identify fish in a mixed-species product that cannot be identified with standard DNA barcoding. A total of 15 fish ball mixtures were prepared with known amounts of Nile tilapia (Oreochromis niloticus), Pacific cod (Gadus macrocephalus), and walleye pollock (Gadus chalcogrammus). Three subsamples from each fish ball underwent DNA extraction, full DNA barcoding (655 bp), and mini-barcoding (226 …

Moisture Sorption Behavior And Shelf Life Prediction Of Teff Seed And Flour, Baba Abdissa, Rudrayya Math, Kodandaramreddy Desham, Srinivasulu Korra

Journal of Applied Packaging Research

Moisture sorption isotherms of Teff seed and its flour were determined over the range of relative humidity (11–92%) using a gravimetric technique at constant temperature (27°C). The results obtained showed that the moisture sorption isotherm of both is almost similar and sigmoid with increasing equilibrium water content at the constant temperature. The curves start raising high above 64% RH indicating the products deteriorates faster above 64% RH. Hence the moisture content equilibrating to 64% RH was taken as critical for both Teff seed and flour variants. The sorption isotherm fits the GAB equation as per GAB generalized equation for sorption …

Plasma Functionalised Liquids: From Bench To Prototype For Safe Fresh Food Preservation, Uta Schnabel

Doctoral

Fresh-cut produce such as lettuce may contain a very high microbial load, including human pathogens. Therefore, the need for antimicrobial interventions at post-harvest stages to prevent microbial growth is evident. Sanitation steps based on non-thermal plasmas at atmospheric pressure opens up innovative food processing possibilities by application at different points along the food chain; for production, modification and preservation, as well as in package treatment of plant- and animal-based foods. Plasma differs from the gaseous state of matter by a certain amount of free charge carriers caused by ionisation processes of the gas atoms and molecules due to the supply …

Sampling The Local Fare: Fishes At The Sam Israel House Pit (45gr76), Soap Lake, Washington, Adam Fruge

All Master's Theses

The Sam Israel site is a precontact archaeological complex with numerous fish bones at the north end of Soap Lake, Washington. Excavated in 1976, the fish remains recovered from there were never fully analyzed prior to this research. Since this inland Columbia Plateau site had thousands of fish bones, it contained untapped potential for our understanding of ancient local fish procurement. As such, I conducted a detailed analysis of 2,862 fish bone specimens from the Sam Israel House Pit locus to: study a larger sample of fish bones in greater detail than was done before; compare the distribution of fishes …
