The macroalgal hydrocolloid industry is a rapidly growing industry with an annual growth in the global production of 2–3 %. Hydrocolloids from macroalgae are mainly in the form of polysaccharides with other nutrients, such as vitamins, minerals, and proteins. Due to its potential industrial applications, macroalgae have been used as raw materials for hydrocolloids extraction. Compared to the conventional extraction methods, emerging innovative assisted extraction technologies (e.g., Ultrasound/Microwave assisted extraction) have been developed to maximise the extraction yields, efficiency and thereby, maintaining sustainability along the process. These novel techniques are considered as clean and green strategies, with a potential for a large-scale production; thus, avoiding or reducing the use of chemicals. However, more research is required to establish their mechanism of action in order to finally implement them at industrial level. This paper reviews the most relevant strategies and technologies involved in the production of hydrocolloids from macroalgae.

大型藻类水胶体产业是一个快速发展的产业，全球产量年均增长2-3％。来自大型藻类的水胶体主要是具有其他营养素（例如维生素，矿物质和蛋白质）的多糖形式。由于其潜在的工业应用，大型藻类已用作提取水胶体的原料。与常规提取方法相比，已经开发了新兴的创新辅助提取技术（例如，超声波/微波辅助提取），以最大程度地提高提取产量，效率，从而在整个过程中保持可持续性。这些新颖的技术被认为是清洁和绿色的策略，具有大规模生产的潜力；因此，避免或减少了化学药品的使用。然而，需要更多的研究来建立它们的作用机理，以便最终在工业水平上实施它们。本文概述了从大型藻类生产水解胶体的最相关策略和技术。
