Abstract
The invention relates to a method for preparing a lipid-rich microalgal flour, which comprises the following steps: (a) providing a microalgal biomass comprising more than 50% of lipids by dry weight of biomass; (b) lyzing the microalgae, (c) concentrating the microalgal lyzate to a solids content of more than 25% by weight, preferably to a solids content of between 35% and 50% by weight, (d) applying a heat treatment to the lyzate thus concentrated, (e) homogenizing at high pressure the lyzate obtained in step (d), so as to obtain a stable emulsion, (f) drying said emulsion to obtain the microalgal flour.

A method for preparing a lipid-rich microalgal flour, comprising
- (a) providing a microalgal biomass containing more than 50% of lipids by dry weight of biomass;
- (b) lyzing the microalgal to for a microalgal lyzate,
- (c) concentrating the lyzate to a solids content of more than 25% by weight, preferably to a solids content of between 35% and 50% by weight,
- (d) heating the concentrated lyzate,
- (e) homogenizing at high pressure the lyzate obtained in step (d), so as to obtain a stable emulsion,
- (f) drying said emulsion to obtain the microalgal flour.
A method for preparing a lipid-rich microalgal flour, comprising which comprises the following steps comprising
- (a) lyzing a Chlorella microalgal biomass containing more than 50% of lipids by dry weight of biomass to form a lyzate,
- (b) evaporating water in said lysate to a solids content 35% and 50% by weight, to form a concentrate,
- (c) heating the concentrate deoxygenate and/or deodorize the concentrate,
- (d) forming a stable oil-in-water lysate emulsion, and
- (e) drying said emulsion to obtain the microalgal flour.
