摘　　要：螺旋藻能利用光能,固定二氧化碳合成如蛋白质、多糖、不饱和脂肪酸等有机物,被誉为人类最理想的食物资源之一。传统的螺旋藻产品形式有藻粉及以其为原料制成的片剂和胶囊等,这类产品加工制备的工艺中包含螺杆泵上料挤压、高速雾化和高温脱水等环节,在此过程中会造成螺旋藻藻丝断裂、细胞破碎及营养物质损失。鲜食螺旋藻是在封闭式光生物反应器中培养,经采收、洗涤、过滤、杀菌而制成的可直接食用的螺旋藻,其口感清爽、无不良气味,正逐渐被人们所接受。首先分析鲜食螺旋藻较传统藻粉的营养优势,然后综述鲜食螺旋藻在现代食品加工中的应用,并对其生产系统的开发前景进行了展望,旨在为螺旋藻新产品研发及产业高质量发展提供借鉴。Spirulina is capable of using light energy and fixing carbon dioxide to synthesize a series of organic substances such as proteins,polysaccharides,unsaturated fatty acids,etc,which is regarded as one of the most ideal food resources for human beings.Traditional Spirulina products are typically formulated as algal powder tablets or capsules.However,the processing and preparation of these products,which involve screw pump feeding and extrusion,high-speed atomization,and high-temperature dewatering,often lead to the rupture of cell filaments,cell fragmentation,and the consequent loss of vital nutrients.In contrast,fresh living Spirulina,a novel product,is cultivated in a closed photobioreactor,and made edible through harvesting,washing,filtering and sterilizing.With its refreshing taste and odorlessness,it is gradually accepted by the general public.This paper firstly analyzed the nutritional advantages of fresh living Spirulina over traditional algal powder,and then reviewed the way of application of fresh living Spirulina in modern food processing,and looked forward to the development prospect of its production system,aiming to provide reference for the research and development of new products and high-quality development of the microalgae industry.
