Process for producing myceliated flour, characterized in that it comprises the following steps: a. preparing a growth medium for fungus growth, wherein the growth medium is a potato-dextrose-agar medium prepared by using 100 to 200 g of potato, 10 to 30 g agar and 10 to 30 g dextrose; wherein step (a) is carried out in a sterile environment; b. inoculating the fungus in the growth medium using a sterile apparatus; c. growing in culture for 15 to 40 days at a temperature of 15 to 35°C; d. preparing matrix grains for inoculation of fungi by: (i) soaking grains in water for 12 h, wherein the volume of water is three times the grain volume; or alternatively boiling the grains for 10 to 20 minutes, (ii) storing the grains in a suitable container to 3/4 of the volume, (iii) sterilizing the grains in a medium designed to be used with food products and (iv) cooling the grains; wherein step (d) is carried out without adding calcium carbonate or agricultural plaster; e. inoculating the matrix grains obtained in step (d) with 0.5 to 2 cm 2 of the mycelium grown in the growth medium and placing them in bags or trays in a sterile environment; f. closing the bags or trays containing the matrix grains and incubating them at a temperature between 15 and 35°C for 15 to 40 days; g. inoculating grains intended to flour production with the fungal mycelium grown in the matrix grain as obtained in step (f); h. incubating the inoculated grains as obtained in step (g) at a temperature between 15 and 35°C for 15 to 40 days; i. dehydrating the myceliated grains obtained in step (h) with continuous air flow at a temperature of 60°C; j. milling the dried grains to produce flour. a. preparing a growth medium for fungus growth, wherein the growth medium is a potato-dextrose-agar medium prepared by using 100 to 200 g of potato, 10 to 30 g agar and 10 to 30 g dextrose; wherein step (a) is carried out in a sterile environment; b. inoculating the fungus in the growth medium using a sterile apparatus; c. growing in culture for 15 to 40 days at a temperature of 15 to 35°C; d. preparing matrix grains for inoculation of fungi by: (i) soaking grains in water for 12 h, wherein the volume of water is three times the grain volume; or alternatively boiling the grains for 10 to 20 minutes, (ii) storing the grains in a suitable container to 3/4 of the volume, (iii) sterilizing the grains in a medium designed to be used with food products and (iv) cooling the grains; wherein step (d) is carried out without adding calcium carbonate or agricultural plaster; e. inoculating the matrix grains obtained in step (d) with 0.5 to 2 cm 2 of the mycelium grown in the growth medium and placing them in bags or trays in a sterile environment; f. closing the bags or trays containing the matrix grains and incubating them at a temperature between 15 and 35°C for 15 to 40 days; g. inoculating grains intended to flour production with the fungal mycelium grown in the matrix grain as obtained in step (f); h. incubating the inoculated grains as obtained in step (g) at a temperature between 15 and 35°C for 15 to 40 days; i. dehydrating the myceliated grains obtained in step (h) with continuous air flow at a temperature of 60°C; j. milling the dried grains to produce flour.
