  • High Pressure Processing (HPP)Technology Hiperbaric

    High Pressure Processing is a cold pasteurization technique which consists of subjecting food, previously sealed in flexible and water resistant packaging, to a high level of hydrostatic pressure (pressure transmitted by water) up to 600 MPa / 87,000 psi for a few seconds to a few minutes. It is the same effect as subjecting the food to an ocean depth of 60 Km deep if an ocean this deep

    Silver processing Silver processing The metal and its alloys Even silver that has been fully work hardened, either by rolling or forging, gradually recrystallizes, even at room temperature. This greatly softens the metal, making it susceptible to scratching and marring. To maintain hardness, therefore, other metals are added to form alloys that are harder, stronger, and less prone to fatigue.
