  • Method of increasing the permeability of cellular materials
    Patent number: 4002772
    Abstract: Cellular food materials have been found to possess a relatively soft texture when they are frozen while under a gas pressure of greater than about 50 psig. This pressure freezing treatment also renders the foodstuff more permeable and porous, resulting in a product that will cook faster, can be dehydrated and rehydrated more quickly, and is more responsive to infusion or extraction processes.
