Abstract
A method of treating microbial biomass includes mixing the microbial biomass in a liquid to form a suspension, the microbial biomass having an initial color, and exposing the suspension to light to form treated microbial biomass, the treated microbial biomass having a treated color. The treated color is lighter than the initial color. The microbial biomass can also have an initial taste and odor that are stronger than a treated taste and odor of the treated microbial biomass.
Claims20
A method of treating biomass, the method comprising:
- mixing the biomass in a liquid to form a suspension;
- and
- exposing the suspension to non-ionizing UV light to lyse the biomass to form treated biomass, wherein the temperature of the suspension reaches between 40° C. and 60° C. during the step of exposing, wherein the treated biomass has a lipid content of between 5% and 15%;
- and
- including the treated biomass as at least a portion of a food product.
A method of producing treated microbial biomass, the method comprising:
- growing microbial biomass;
- harvesting the microbial biomass;
- mixing the microbial biomass in a liquid to form a suspension;
- exposing the suspension to non-ionizing UV light to lyse the microbial biomass to form the treated microbial biomass, wherein the temperature of the suspension reaches between 40° C. and 60° C. during the step of exposing, and wherein the treated biomass has a lipid content of between 5% and 15%;
- separating the treated microbial biomass from the suspension;
- and
- packaging the treated microbial biomass.
