Sterilization by means of heat, irradiation and gas are methods universally used for the production of microbiologically safe pharmaceutical preparations, medical devices, and foods. However, in many cases limited chemical and physical stability, interaction with the sterilizing agent, and legal restrictions prohibit the use of these methods. About two decades ...

Simulated food particles with conservative (fast moving and slow heating) properties are required for validation of multiphase aseptic processing for production of shelf-stable low-acid foods. The validation process requires simulated particles to contain residence time tags, thermosensitive implants, and/or bioloads for temperature detection, time-temperature integration, and bactericidal efficacy confirmation. Conservative ...

Heat generated by the specific dynamic action (SDA) associated with feeding is known to substitute for the thermoregulatory costs of cold-exposed endotherms; however, the effectiveness of this depends on food temperature. When food is cooler than core body temperature, it is warmed by body heat and, consequently, imposes a thermoregulatory ...

This paper's main issue is a strong advocacy in favour of an a priori classification of thermal environments that can be really functional to comfort assessment: Class 1, environments where comfort conditions can be established (comfort-prone environments), and Class 2, environments where this is not practically feasible. The former, which ...

Because lycopene is a powerful biological antioxidant, its delivery to humans is of major concern. cis-Lycopene isomers are more bioavailable than the all-trans isomers and thus more efficiently absorbed. Tangerine tomatoes, whose lycopene isomeric content is almost all tetra-cis, provide a useful food source for comparing cis- and trans-isomer absorption. ...
