Development of effective heat treatments is crucial to achieve food products safety, and predictive microbiology is an excellent tool to design adequate processing conditions. This work focuses on the application of a modified Gompertz model to describe the inactivation behaviour under time-varying temperature conditions at the surface of a food product. Kinetic studies were carried out assumin...

A pulsed electric field (PEF) reactor that has two flow paths separated by a membrane was constructed for sake pasteurization. The treatment and cooling solutions were supplied to the in contact with ground electrode high-voltage electrode, respectively. characteristics of microbial inactivation continuous operation novel PEF investigated using NaCl solution containing Escherichia coli as model...

Predictive microbial models generally rely on the growth of bacteria in laboratory broth to approximate the microbial growth kinetics expected to take place in actual foods under identical environmental conditions. Sigmoidal functions such as the Gompertz or logistics equation accurately model the typical microbial growth curve from the lag to the stationary phase and provide the mathematical b...

The objectives of this study were to investigate the effects processing parameters (relative humidity (RH), temperature, and exposure time) on ethylene oxide (EtO) microbial inactivation Salmonella spp. evaluate Enterococcus faecium NRRL B2354 as a suitable surrogate for cumin seeds. Five grams seeds inoculated with either or E. treated EtO at different temperatures (46, 53, 60 °C) RH (30, 40, ...

Incorporation of black soldier fly larvae (BSFL) in fecal sludge management shows promise as a resource recovery strategy. BSFL efficiently convert organic waste into valuable lipids and protein, which can be further processed commercial products. Ensuring the microbial safety waste-derived products is critical to success resource-oriented sanitation requires development effective treatment. Th...

A kinetic model was established for the inactivation of endotoxins in water at temperatures ranging from 210°C to 270°C and a pressure of 6.2 × 10(6) Pa. Data were generated using a bench scale continuous-flow reactor system to process feed water spiked with endotoxin standard (Escherichia coli O113:H10). Product water samples were collected and quantified by the Limulus amebocyte lysate assay....

Disinfection of contaminated water using solar radiation (SODIS) is known to inactivate bacteria. Its inactivation efficiency depends on local conditions where the disinfection is made. This study was aiming to test the efficiency of solar disinfection using different water parameters as low-cost household water treatment technology. Inactivation of microbes was tested using fecal coliform as t...

Pectin methylesterase (PME) is a methyl ester group hydrolytic enzyme of either plant or microbial origin. Importantly, endogenous PMEs in fruits can catalyze the demethoxylation pectin with bulk release methanol, largely impacting fruit juice and wine industries. Here, we demonstrated radio frequency (RF) heating for inactivation investigated relevant mechanisms underpinning enzymatic inactiva...

The construction of optimized biological fuel cells requires a cathode which combines the longevity microbial catalyst with current density an enzymatic catalyst. Laccase-secreting fungi were grown directly on cell to facilitate exchange inactive enzymes active enzymes, goal extending lifetime laccase cathodes. Directly incorporating laccase-producing fungus at extends operational cathodes whil...
