A pressure sensor device and its use for confirming achievement of a selected pressure in a high pressure process (HPP) for sanitizing food is disclosed. The device includes at least a base and a sheet, each of which is substantially impermeable to the working fluid of the HPP and is deformable at the selected pressure. Microcapsules interposed between flat overlapping portions of the base and sheet contain a color former and burst upon pressurization of the environment surrounding the device. Release of the color former is detected to confirm that the pressurization occurred. The device can be associated with one or more foodstuffs (e.g., a packaged food product or a group of such packages) and remain associated therewith to continuously indicate that the foodstuff(s) have been subjected to the selected pressure and are therefore sanitized.

Sensor for high pressure processing of articles

A method for permanently coloring fruits (cherries) and vegetables using carmine and other anthraquinones, using mixtures of multivalent metal ions and acid. The cherries are infused with a mixture of calcium ions, other multivalent metal ions, and carmine dye, at a pH at which the carmine is in soluble form. The cherries are then infused with an acidification solution which results in the preciptation of an insoluble carmine-metal ion complex within the cherries. Unused dye is treated and recycled.
