C-phycocyanin (C-PC), a water-soluble blue pigment, was extracted from microalgae Arthrospira sp. C-PC could be a good substitute for synthetic pigments with high antioxidant activity. However, C-PC is unstable due to sensitivity to temperature, light, pH and oxygen; therefore, applications of C-PC in food and other products are limited. Microencapsulation of C-PC using freeze-drying is a solution to this problem and is considered a suitable method for drying the heat-sensitive pigment.

通过不同壁材料的冷冻干燥增强来自节旋藻的 C-藻蓝蛋白的微胶囊化。


C-藻蓝蛋白（C-PC）是一种水溶性蓝色色素，从微藻节旋藻中提取。 C-PC可以作为合成颜料的良好替代品，具有高抗氧化活性。但C-PC由于对温度、光、pH值和氧气敏感而不稳定；因此，C-PC在食品和其他产品中的应用受到限制。使用冷冻干燥对 C-PC 进行微胶囊化是解决该问题的方法，并且被认为是干燥热敏颜料的合适方法。
