Animal-based proteins are the most consumed worldwide given their well-balanced nutritional composition. However, the growing demand for animal proteins will not be sustainable due to their low conversion efficiency and high environmental footprint. Specific consumers' dietary restrictions and modern trends emphasize the importance of finding alternative sustainable non-animal sources to meet future food (and, in particular, protein) global needs. Algal biomass is considered a relevant alternative, presenting advantages over terrestrial biomass such as higher growth rate, low water consumption, no competition for arable land, carbon-neutral emissions, and production of numerous bioactive compounds. This review provides an overview of recent research advances on algae as source of proteins, including production strategies from relevant protein-producing species. Particular emphasis will be given to algae protein current applications and forthcoming challenges of their use. Nutritional and functional aspects of algae biomass or its protein-enriched fractions will be overviewed.
由于其营养成分均衡，动物蛋白是目前在全球范围内消费最多的蛋白质。然而，由于动物蛋白的低转化率和高环境足迹，其增长需求将不可持续。特定消费者的饮食限制和现代趋势强调了寻找替代可持续的非动物来源以满足未来全球食物（特别是蛋白质）需求的重要性。藻类生物量被认为是一种相关的替代品，与陆地生物量相比具有更高的增长率、低耗水量、不与耕地竞争、碳排放中性以及可生产多种生物活性化合物等优势。本综述概述了藻类作为蛋白质来源的最新研究进展，包括相关产蛋白物种的生产策略。特别强调了藻类蛋白的当前应用以及其应用面临的挑战。藻类生物量或其富含蛋白质的部分的营养和功能方面也将进行综述。
