Seaweed as an alternative protein source: Prospective protein extraction technologies

Demand for food production has increased due to population growth. The negative environmental impact of animal agriculture necessitates the search alternatives protein-based products. Potential health benefits from micronutrient-rich seaweeds have attracted significant attention further research. This encourages use seaweed as an alternative protein-rich source. However, traditional protein extraction presents drawbacks because energy and water-intensive treatments poor yield, which limit their application. There is urge cost-effective, novel, sustainable technologies at right techno-economics. Thus, this review article discusses economic potential proteins identifies applied extract limitations. A detailed analysis novel methods that could potentially be utilized enrich presented. Various quantification/qualification approaches reported in literature been thoroughly assessed compare advantages disadvantages. Technologies like pulsed electric field, ultrasound- microwave-assisted extraction, high-pressure processing, subcritical-water huge sustainably yet are relatively under-explored. More research required develop insights on process-quality inter-relationship these improved extraction. Essential amino acid index, digestibility corrected score, digestible indispensable score best evaluate quality human consumption. studies barely covered aspects, including protein's sensorial quality.
