A New Model To Help Prevent Foodborne Disease, Sergio Alvarez 2020 University of Central Florida

A New Model To Help Prevent Foodborne Disease, Sergio Alvarez

Rosen Research Review

Shellfish, such as oysters, are a well-known source of foodborne diseases. A bacterium called Vibrio vulnificus, commonly found in shellfish, can cause particularly severe illness. Unfortunately, regulations aimed at improving food safety also have the potential to damage the fragile economic status of small coastal communities that depend on oyster harvesting. Rosen College of Hospitality Management's Dr. Sergio Alvarez has led the development of a new bioeconomic model that has the potential to help improve food safety while minimizing economic harm.

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 ...

Veterinary Diagnostic and Production Animal Medicine Publications

We investigated the anti-Campylobacter activity of pinocembrin and its mechanism of action, as well as Campylobacter responses to pinocembrin treatment at the genetic and phenotypic levels, using C. jejuni NCTC 11168 and a multidrug efflux system repressor mutant (11168ΔcmeR). At its minimal inhibitory concentration, pinocembrin significantly increased cell membrane permeability of Campylobacter. Interestingly, at sub-inhibitory concentrations, pinocembrin did not significantly alter membrane functionality and it increased bacterial fitness. Treatment with pinocembrin evoked decreased expression of ribosomal proteins and down-regulation of several NADH dehydrogenase I chain subunits and proteins involved in iron uptake. This suggests altered protein production and redox cycle ...
