Abstract

Omega-3 fatty acids are vital for human health, yet traditional sources such as fish oils face challenges including overfishing, environmental concerns, and contaminants. This review explores algal oils as a sustainable and efficient alternative for omega-3 production. Microalgae, cultivated under controlled conditions, offer a vegan, eco-friendly solution for producing high-quality DHA and EPA. Advances in biotechnological methods, such as genetic engineering and hydrothermal liquefaction, have optimized algal oil yields, enhancing its scalability and affordability. The review highlights innovative extraction techniques, including ultrasonication and enzymatic methods, which preserve oil quality while minimizing environmental impact. Furthermore, the integration of algal omega-3 s into nutraceuticals, aquaculture, and functional foods is transforming health and environmental sustainability. This work underscores the potential of algal omega-3 s in addressing global dietary needs while promoting sustainable practices. By bridging scientific innovation and environmental awareness, algal oils present a compelling path forward for human health and ecological preservation.

藻类油作为必需omega-3脂肪酸的可持续来源的综述

Omega-3脂肪酸对人体健康至关重要，但传统的鱼油来源面临着过度捕捞、环境问题和污染物等挑战。这篇综述探讨了藻类油作为一种可持续和有效的替代omega-3生产。在受控条件下培养的微藻，为生产高品质的DHA和EPA提供了素食、环保的解决方案。生物技术方法的进步，如基因工程和水热液化，优化了藻类油的产量，提高了其可扩展性和可负担性。综述重点介绍了创新的提取技术，包括超声波和酶的方法，以保持油的质量，同时最大限度地减少对环境的影响。此外，将藻类-3 - 5整合到营养品、水产养殖和功能食品中，正在改变健康和环境的可持续性。这项工作强调了藻类-3 - 5在解决全球饮食需求的同时促进可持续实践的潜力。通过连接科学创新和环保意识，藻类油为人类健康和生态保护提供了一条令人信服的道路。
