Abstract
The present invention relates to a method for preparing, by fermentation, lipid-rich compositions of microalga flour having optimised organoleptic properties, characterised in that the microalgae are cultured in a minimal culture medium.
Claims15
1-23. (canceled)
A process for the preparation of compositions of flour of microalgae of optimized organoleptic quality comprising culturing the microalgae in a minimum culture medium under fermentative conditions, wherein the minimum culture medium comprises chemically defined elements comprising a source of carbon, a source of potassium, a source of phosphorus, a source of nitrogen, a source of sulfur, a source of magnesium, a source of calcium, a source of iron, sources of trace elements, and one or more vitamins;
- wherein:
- (a) the minimum culture medium does not comprise choline and inositol;
- (b) the minimum culture medium comprises greater than zero, but not more than about 1 g/l of MgSO4;
- (c) the minimum culture medium comprises greater than zero, but not more than about 0.2 g/l of (NH4)2SO4;
- wherein the microalgae in the minimum culture medium reaches a cell density of at least about 70 g/L;
- and
- wherein the microalgae belong to the genus Chlorella.
