Abstract (en)
A packaged foodstuff which is to be heated and/or cooked in its packaging, the packaging having at least one microperforation through which gas within the packaging can escape when the packaged foodstuff is heated. The perforation should be small enough substantially to prevent water from entering the package when the package is heated in water, and the packaging will usually contain more than one microperforation. The invention can be used to heat packaged foodstuffs without puncturing the packaging which would otherwise allow the heating water to contaminate the foodstuff, whilst at the same time allowing air in the packages to escape without over-inflation thereof.
