Method and apparatus for the production of a vacuum raised foodstuff

摘要

A vacuum raising apparatus for the production of an expanded foodstuff comprises a fluid permeable mould 10 for constraining the foodstuff 22. The permeability of the mould 10 is substantially uniform throughout so that during vacuum raising, fluids from the foodstuff can escape uniformly through the entirety of the mould 10. The mould 10 may comprise two separable portions. The vacuum raising apparatus may comprise a sheet of alternating flats 14 and troughs 12. Also disclosed is a method of vacuum raising a foodstuff comprising forming first and second edible components, the second component being a fat liquid at body temperature and a protein, co-extruding the first component around the second component, constraining the extruded product within a mould as described and heating the extruded product within the mould under vacuum.
