The present disclosure relates generally the field of fungal mycelium based edible meat substitute products.
Demand for edible products that can provide a high protein content which is drawn from a non-animal source is increasing. Driven by increasing awareness of personal health, edible products that include non-animal sourced components such as proteins and fibers are considered as a healthier alternative to animal protein based products. In particular, there is growing demand for edible meat substitutes that mimic meat in its composition and texture, but are composed of non-animal components, which can reduce reliance on animals such as cows, chicken, and pigs, and reduce the carbon footprint posed by such animals. Thus, there is a need for non-animal protein sources that can facilitate large scale production and adoption of non-animal based edible products.
Embodiments described herein relate generally to methods for growing filamentous fungi from pea protein residual waste streams for obtaining edible meat substitute products that resemble animal meat in their texture and morphology.
In some embodiments, a method of forming an edible meat substitute product comprises obtaining a liquid waste stream from a pea protein processor; adjusting the pH of the liquid waste stream to be in a range of 5.5 to 6.0 so as to form a growth media; growing fungal cells in the growth media such that the fungal cells produce a mycelium mass; separating the mycelium mass from the growth media; and concentrating the mycelium mass to obtain a fibrous mycelium mass having a protein content of greater than 40 wt % of a dry mass of the mycelium.
In some embodiments, an edible meat substitute product is formed by the process of obtaining a liquid waste stream from a pea protein processor; adjusting the pH of the liquid waste stream to be in a range of 5.5 to 6.0 so as to form a growth media; growing fungal cells in the growth media such that the fungal cells produce a mycelium mass; separating the mycelium mass from the growth media; and concentrating the mycelium mass to obtain a fibrous mycelium mass having a protein content of greater than 40 wt % of a dry mass of the fibrous mycelium mass.

In some embodiments, the method 100 may include removing a volume of a broth (e.g., siphoned broth). The siphoned broth can contain the fungal cells and the growth media. For example, the siphoned broth can include a solution containing the fungal cells and the growth media. Removing a volume of broth can include discretely removing a volume of broth. For example, a volume of broth can be siphoned from a container containing the broth in a batch process, or be continuously removed from the broth. For example, a volume of broth can flow out of the container containing the broth in a continuous process.
The method 100 may include adding fresh growth media to a container containing the broth. The broth can be a fermentation broth. Nutrients (e.g., sugar, phosphate-containing compound, or nitrogen-containing compound) can be added in a batch growth configuration. For example, the nutrients can be added after a predetermined amount of time (e.g., after 1 hour, 2 hours, 3 hours, 6 hours, or 12 hours, inclusive). The concentrations of none or at least one of the nutrients of the fresh growth media can be brought to the concentrations of nutrients of the original growth media described in operation 102. The fresh growth media can have a volume that is greater than, less than, or equal to a volume of growth media that was lost from the original growth media during growth of the fungal cells in the original growth media.
In one example, after 6 hours, the concentration of sugar, phosphate-containing compound, and nitrogen-containing compound in the fresh growth media is increased. Nutrients are added to the broth to create a new broth. Nutrients are added to the broth to bring the concentrations of sugar, phosphate-containing compound, and nitrogen-containing compound of the new broth to the concentrations of sugar, phosphate-containing compound, and nitrogen-containing compound, respectively of the original growth media.
In one example, after at least 12 hours, 50-95% of the broth can be removed. Fresh media can be added containing nutrients (e.g., sugar, phosphate-containing compound, or nitrogen-containing compound). The nutrient concentration of the broth can be increased by adding fresh growth media.
Nutrients can be added in a continuous growth configuration. For example, a volume of broth (e.g., 0.01 vol %, 1 vol %, 5 vol %, 10 vol %, 25 vol %, 50 vol %, or 95 vol %, inclusive) can be removed from the container containing the fungal cells and the growth media. Fresh growth media can be added to the container containing the broth. The fresh growth media can be provided as a continuous flow. The volume of the broth in the container can be monitored to stay at a specified level. For example, the volume of the broth in the container can stay at a fixed volume. The volume of fresh growth media that is added can be equal to the volume of broth that is lost from the container.
The method 100 includes separating the mycelium mass from the growth media, at 108. Separating the mycelium mass from the growth media can be performed using gravity straining, centrifugation, a belt press, a filter press, a mechanical press, a drum dryer, or any other suitable process. The separated mycelium mass can have a moisture content of greater than 90 wt %. For example, the separated mycelium mass can have a moisture content of 91 wt %, 92 wt %, 93 wt %, 94 wt %, 95 wt %, 96 wt %, 97 wt %, 98 wt %, or 99 wt %, inclusive. During the separation process, the mycelium mass can be washed with water, ethanol, acid, base or other solvent. Recovered filtrate can be reused or discarded. Cell walls of the mycelium mass can be disrupted, for example, through lysing. Lysis may be performed by adjusting the pH to below 4 or above 9, by adding lysis enzymes, by raising the temperature in a range of 40° C. and 60° C. in a range of 1 and 24 hours, or any other suitable lysis method. Following separation, additives (e.g., food additives) can be mixed with the mycelium mass. Additives can include vegetable or animal proteins, fats, emulsifiers, thickeners, stabilizers, and flavoring, for example, when the mycelium mass is being formed into an edible product.
The method 100 may include concentrating the mycelium mass, at 110. Concentrating the mycelium mass may include filtering the mycelium mass to obtain a fibrous mycelium mass. The fibrous mycelium mass can have a protein content of greater than 40 wt % of a dry mass of the mycelium. For example, the mycelium mass can have a protein content of 45 wt %, 50 wt %, 60 wt %, 70 wt %, 80 wt %, or 90 wt %, inclusive, of the dry mass of the mycelium mass.
In some embodiments, the method 100 may include autoclaving the growth media before growing the fungal cells in the growth media. For example, the growth media can exposed to temperatures and pressures that sterilizes the growth media. In some embodiments, the method 100 may include diluting the liquid waste stream by a factor in a range of 8 to 12. For example, the liquid waste stream can be diluted by a factor 8, 9, 10, 11, or 12, inclusive.

Following are some examples of growing filamentous fungi from pea protein residual waste streams. These examples are for illustrative purposes only and should not be construed as limiting the disclosure in any shape or form.
In one example, a liquid waste stream from a pea protein processor is obtained. The waste stream was added to a 3 L benchtop bioreactor at 2 L working volume and autoclaved. Following autoclaving, pH was adjusted to 5.8 using 1M citric acid. 50 mL of Neurospora crassa was added as a seed to the bioreactor. The bioreactor was operated for 24 h at 32° C., with an agitation of 250 rpm, airflow of 1 vvm, and a constant pH of 5.8. At the end of the run, biomass was filtered from the solution and measured. The dry weight was approximately 12 g L−1. This run represents the ability to use this discarded pea protein processing waste stream as a filamentous fungi nutrient media. In some embodiments, the waste stream is certified organic allowing for access to an organic sugar source. In some embodiments, the flavor of the waste stream is minimal and thus the final biomass had minimal flavor.
The fibrous mycelium mass can be used in a single or combination of ways. For example, the fibrous mycelium mass can be cooked at a temperature of less than 100° C. (e.g., 90° C., 80° C., 75° C., or 50° C., inclusive) for 1-60 minutes in dry or steam environment. The fibrous mycelium mass can be cooked at a temperature range of 100° C. to 200° C. (e.g., 100° C., 125° C., 150° C., or 200° C., inclusive) for 1-60 minutes in dry or steam environment. The fibrous mycelium mass can be cooked in a water bath at less than 100° C. for 1 minute to 120 minutes (e.g., 1, 2, 5, 10, 20, 40, 60, 80, 100, or 120 minutes, inclusive).
In some embodiments, the fibrous mycelium mass can be stored. The fibrous mycelium mass can include additional ingredients. The fibrous mycelium mass can be cooked. The fibrous mycelium mass can be frozen at less than 0° C. under ambient or vacuum conditions, and/or refrigerated at less than 5° C. under ambient or vacuum conditions. The fibrous mycelium mass can be stored indefinitely in sealed container.
Producing the fibrous mycelium mass can include tuning the texture of the fibrous mycelium mass. Texture of the fibrous mycelium mass can be tuned by chemical washing of the mycelium mass. Alternatively, texture can be altered by controlling the water content of the mycelium mass. Texture can also be altered through the addition of different nutrients which determine mycelium mass growth and morphology. The density of final mycelium mass can be controlled by altering initial water content and drying conditions to produce a heavier or lighter end product.
