Seaweed proteins as a novel protein alternative: Types, extractions, and functional food applications

Seaweeds, as a dietary protein source originated in Asian countries and later expanded towards France, Chile, etc. Food applications have been narrowed down due to complications in extraction. Therefore, products are not yet available in the market. Extraction of other phytochemicals along with seaweed proteins provides value addition in food products. Therefore, a trend has emerged to extract protein from edible seaweeds with many health beneficial applications. Also, consumption of many animal proteins like meat are now becoming a threat on humans due to infectious viral diseases. Hence, seaweed proteins are emerging as a global alternative source of protein.
