Eight foodborne yeasts were screened for sensitivity to high-pressure (HP) inactivation under a limited number of pressure-temperature combinations. The most resistant strains were Zygoascus hellenicus and Zygosaccharomyces bailii. The latter was tak

A study was carried out on the kinetics of thermal inactivation of pectinesterase (PE), extracted from the pulp of Valencia and Navel oranges. Moreover, the influence of intrinsic factors on the kinetics of Navel orange PE was investigated. In a citr

Degradation of chlorophyll in broccoli juice occurred at temperatures exceeding 60 degrees C. Chemical analysis revealed that degradation of chlorophyll a and b to pheophytin a and b, respectively, followed first-order kinetics and that chlorophyll a

Broccoli juice greenness was marginally affected by pressure at low temperatures (30-40°C). At 800 MPa and slightly higher temperatures (50-60°C), first-order degradation of green color was observed. The greenness loss was suggested to be due to ch

Irreversible combined pressure-temperature inactivation of the food quality related enzyme polyphenoloxidase was investigated. Inactivation rate constants (k) were obtained for about one hundred combinations of constant pressure (0.1-900 MPa) and tem

Heat and combined pressure−temperature degradation of chlorophyll in broccoli juice have been studied on a kinetic basis. A treatment at 100 °C and atmospheric pressure during 37 min resulted in a 90% decrease in total chlorophyll content of brocc

Both isothermal and isobaric−isothermal inactivation of soybean lipoxygenase (LOX) could be accurately described by a first-order kinetic model. Thermal inactivation of LOX at atmospheric pressure proceeded in the temperature range 60−70 °C, whe

In previous research, kinetics for irreversible inactivation of soybean lipoxygenase (LOX) by combined pressure and temperature have been thoroughly studied in the pressure range 0.1−650 MPa at tem...

High-pressure and thermal inactivations of avocado polyphenol oxidase (PPO) were studied for enzyme systems with pH 4−8. Both pressure and temperature inactivation of the enzyme followed first-order kinetics in the pH range 5−8 but showed deviati

An important issue in the application of high pressure technology in the food preservation/processing industry is regulatory approval, which focuses upon microbiological and toxicological safety of food products. High pressure preservation processes
