High protein ingredients of microalgal origin: Obtainment and functional properties

Using proteins from microalgal sources can serve as a sustainable alternative to meet world food demand. The isoelectric precipitation extraction method can be applied on a large scale, achieving high yields. Protein extracts present potential application in specific foods for protein supplementation. Protein extraction can be allied to other biocomposites extraction, such as carbohydrates and lipids for biofuels production.
