Edible myceliated composition

A process for the preparation of an edible myceliated composition comprising the following steps:

• (i) Preparing a sterilized liquified inoculum of a filamentous fungal culture, preferably of a lignocellulolytic fungus by:
• (1) adding under sterile conditions to a sterilized cereal and optionally legume-containing substrate, said substrate comprising at least oat, an amount of the filamentous fungal culture, and let the mixture ferment until the substrate is colonized with hyphae forming a mycelium network to obtain a fermented substrate;
• (2) adding a sterilized isosmotic liquid to the fermented substrate in (1), and liquefying by homogenization the mixture of (2) to obtain the sterilized liquified inoculum;
• (ii) Preparing a sterilized fermentable substrate, said substrate comprising one or more cereals including oat and rice, and one or more legumes or a textured isolated protein of these legumes, by hydrating the substrate and disposing it in a container adapted to allow exchange of gases, and sterilizing the container with the substrate;
• (iii) Inoculating in sterile conditions the sterilized fermentable substrate of step (ii) with the liquified inoculum of (i);
• and
• (iv) Culturing the sterilized fermentable substrate with the liquified inoculum for a time to allow the growth of hyphae and formation of a mycelial network within the fermented substrate to obtain an edible myceliated composition.
