The human population is steadily increasing and new alternative protein sources are necessary to secure food safety. There is a growing interest in macroalgae, or seaweed, as an alternative food source as they are rich in nutrients, minerals and carbohydrates. Among the diverse species of macroalga, , a red seaweed of growing interest due to its high protein content, represents a potential candidate for contributing to food security and animal feed. Novel methods are being investigated for extracting valuable components from seaweed, including protein. In this study, pulsed electric field (PEF) and enzymatic assisted extraction (EAE) were tested to investigate whether the methods, alone or in combination, were sufficient for protein extraction from . The results show high extraction yields of dry matter consisting mostly of carbohydrates and ash when using EAE. The results point to a concentration of protein, including essential amino acids, in the pellet after extraction with a combination of PEF and EAE, or EAE alone. There is potential for the protein-rich pellet in animal feed. For the supernatant, there are potential uses within biostimulants.

人口在稳步增长，需要新的替代蛋白质来源来确保食品安全。大型海藻，即海藻，作为一种替代食物来源越来越受到关注，因为它们富含营养、矿物质和碳水化合物。在各种各样的大型海藻物种中， ，一种因其高蛋白含量而日益受到关注的红藻，是有助于粮食安全和动物饲料的潜在候选者。人们正在研究从海藻中提取有价值成分（包括蛋白质）的新方法。在本研究中，测试了脉冲电场（PEF）和酶辅助提取（EAE），以研究这些方法单独使用或联合使用时是否足以从 中提取蛋白质。结果表明，使用EAE时，干物质的提取率很高，主要成分是碳水化合物和灰分。结果表明，在联合使用PEF和EAE或单独使用EAE提取后，沉淀中含有包括必需氨基酸在内的蛋白质。富含蛋白质的沉淀在动物饲料方面具有潜力。对于上清液，在生物刺激剂方面有潜在用途。
