Spirulina is a blue-green algae that occurs naturally in freshwater and marine habitats. It has a long history as a food supplement in many countries. Spirulina contains green chlorophyll and phycobilins, which absorb sunlight and have a role in photosynthesis. The phycobilins found in spirulina are blue phycocyanins which are extracted to create a vivid blue colour. DDW’s blue spirulina concentrate is gently produced using water extraction and is available as a standard powder or a liquid which has been stabilised for light protection. The stabilised liquid offers almost double the phycocyanin retention when exposed to light when compared with standard products. It can be considered a colouring food.
Typical Applications for Spirulina
This colour is primarily used in confectionery, frostings, ice cream/frozen novelties, dessert coatings/toppings, dry beverage mixes, yoghurts, puddings/custards, and gelatin. DDW spirulina and spirulina blends provide natural alternatives to replace synthetic Brilliant Blue and other synthetic colouring blends in novelty blue, mint, or pistachio flavored ice cream, panned candies, jelly sweets, or boiled sweets. It can also be used to overcome grey tones in fondant, and yoghurt.
Due to spirulina’s poor light stability, it is recommended for products with opaque packaging.
