Techniques for Creating, Extracting, Separating, and Purifying Food and Feed Using Microalgae

Abstract

Numerous Microalgae (MA) species are utilized for their significant biotechnological possibilities in generating various biomolecules applicable across multiple industrial sectors. The primary issue of biotechnology processes is achieving economic viability by producing highly valuable chemicals. Many of these chemicals are sequestered within the cells, necessitating efficient gathering, wellness, and purifying methods. New developments in physicochemical therapies, such as supercritical liquid extraction, ultrasound-assisted gathering, pulsed electrical fields, and solvent-free processes, aim to develop sustainable and adaptable methods for efficient and pure extraction of the desired goods. This article examines the existing methodologies, emphasizing select instances of recently granted patents about gathering, rehabilitating, and purifying microalgal elements at small and large levels, in alignment with the global shift towards bio-based outcomes.
