Heat-Stable Spirulina Blue Formulations Widen Food and Beverage Use
Food makers have long avoided phycocyanin in baked or pasteurized foods because heat and acid break the protein and fade the color, but new formulations with stabilizers, encapsulation, and modified protein forms tolerate higher temperatures and lower pH. Brands now test spirulina blue in beverages, gummies, and dairy, and suppliers publish stability data at 60 to 80 degrees Celsius and pH 4 to 7. Stabilized grades sell at 20% to 50% above standard phycocyanin. Each stability improvement widens accepted uses, and confectionery makers report better shelf life in cool-chain products when formulations are matched carefully.
