Decolorized spirulina and methods for producing the same

A food-grade spirulina biomass characterized by at least one of the following:

• a) color coordinates in the range of 15<L<90, 0<a<95, 0<b<55, wherein the maximum value (a+b) is equal to or smaller than (L*1.2), as measured according to CIELAB color space;
• b) having spectrum absorbance at the maximum absorbance peaks in the range of 400-560 nanometers;
• c) RGB color space values in the range of 50>R>255 wherein each G and B is equal to or smaller than (R−30).
• d) CMYK color space values of C=0, 0.1>M>0.8, 0.1>Y>0.8, 0.01>K>0.5, wherein K<M*0.6 and M*1.5>Y>M*0.5;
• wherein the biomass has protein content in the range of 70% to 99% calculated based on dry weight.
