Natural pigments such as phycocyanin are highly sensitive to environmental conditions and therefore require stabilization to broaden their applications in functional products. This study aimed to evaluate the effect of varying ratios of maltodextrin and soy protein isolate (SPI) on the physical properties and encapsulation performance of freeze-dried phycocyanin microcapsules. Phycocyanin was extracted using phosphate buffer and encapsulated in three formulations with different maltodextrin–SPI...

Phycocyanin, a natural blue pigment from Spirulina platensis, exhibits strong antioxidant activity but is highly unstable under light, heat, and pH variations, limiting its practical applications. This experimental study addresses the lack of systematic optimization data on maltodextrin–soy protein isolate (SPI) wall matrices for phycocyanin microencapsulation via freeze-drying. Phycocyanin was extracted using phosphate buffer and encapsulated at different maltodextrin:SPI ratios (9:1, 8:2, and...

Spirulina platensis, a blue-green algae abundant in tropical regions, is rich in minerals, vitamins, fibers, and pigments, with low nucleic acid content. It has unique chromoproteins called phycobiliproteins, notably phycocyanin, used in various applications. This study aims to optimize phycocyanin extraction using different solvents (distilled water and sodium phosphate buffer pH 6.7) and methods (freeze-thaw and sonication). Spirulina platensis biomass was extracted in both solvents, then some...
