1. A process for the preparation of an edible proteinaceous substance, suitable for use in a foodstuff, comprising fungal cells, the process comprising:
- a. fermenting fungal cells of the order Mucorales in an aqueous liquid contained in a fermenter vessel, the liquid comprising an assimilable nitrogen (N) source and an assimilable carbon (C) source, and mixing the liquid and cells during fermentation;
b. reducing the RNA content of the fungal cells to below 4% by weight (wt %);
c. before or after (b), removing at least some of the water from the mixture of fungal cells and aqueous liquid; and
d. processing the fungal cells into an edible substance.

Abstract
The preparation of a proteinaceous substance suitable for use in a foodstuff is described which comprises fungal fells of the order Mucorales. The cells are grown in a fermentor vessel in a liquid which is mixed during fermentation, after which the RNA content of the fungal cells is reduced to below 4% the fungal cells processed into an edible substance. This substance is then mechanically texturized into edible textured product for inclusion into foodstuffs, for example in the form of chunks as a meat substitute.
