High Pressure Processing (HPP) is a non-thermal (5ºC - 20ºC) food and beverage preservation method that guarantees food safety and achieves an increased shelf life, while maintaining the organoleptic and nutritional attributes of fresh products. It is based on the use of high isostatic pressure transmitted by cold water of up to 6,000 bar /600MPa /87,000 psi, held for a few minutes.

Background: Hydraulic injection injury occurs when the outer layer of skin is broken by a jet of fluid under pressure. Although serious reported instances of hydraulic injection have occurred at pressures over 100 bar (1450 psi), anecdotal evidence suggests hydraulic injection injury may occur at pressures as low as 7 bar (101.5psi) [1].

All modern petrol injection systems use indirect injection. A special pump sends the fuel under pressure from the fuel tank to the engine bay where, still under pressure, it is distributed individually to each cylinder. Depending on the particular system, the fuel is fired into either the inlet manifold or the inlet port via an injector.This works much like the spray nozzle of a hose, ensuring ...
