Supablu HS1 is a next-generation natural blue food colourant, free from petrochemicals and coal-tar derivatives, yet delivering the same brilliance and reliability you expect from synthetic dyes.
Developed using our proprietary photobioreactor technology, Supablu HS1 gives manufacturers a stable, compliant and truly sustainable colour solution for the future of food.
Naturally derived from Spirulina. Bake-stable. pH-stable. Scientifically proven.
Our controlled, closed photobioreactor process ensures consistent purity, vibrant hues, and scalability for pilot batches to global supply.
SupaBlu delivers bake stability that far exceeds anything currently on the market, standing up to high-heat and other demanding processing conditions. It also maintains its colour integrity down to pH 3.2, a level no colour house has achieved to date with a natural blue. This breakthrough opens the door to new clean-label innovation across a wide range of food and beverage applications, with the added nutritional benefits rarely found in artificial colours.
You get the full functionality of a synthetic blue, while meeting rising consumer and regulatory expectations around transparency, sustainability and modern food-processing needs.
Supablu shows excellent colour stability after addition to hot sugar syrups, with no flocculation. When added to neat sugar syrup at 80°C over 96% of the blue intensity is retained. In syrup/buffer mixes, Supablu outperforms other CPC powders as no flocculation occurs.
Supablu meets the highest international standards for food safety and quality. It is approved by both the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA) for use in a wide range of food and beverage applications. Our world-class facility also has a SALSA audit pass, meaning we are a Safe and Local UK Accredited food producer.
Every batch is produced under controlled, traceable conditions, ensuring consistent pigment quality, regulatory compliance, and full supply-chain transparency. Manufacturers can adopt Supablu with confidence, knowing it’s clean label, compliant, and market ready across major global regions.
Behind Supablu is ScotBio’s modular photobioreactor system, a breakthrough in sustainable ingredient production. By integrating directly into food and ingredient supply chains, our reactors are designed to utilise partners’ waste heat and CO₂, significantly reducing operating costs and carbon footprint, while enabling local, fully traceable production.
We invite you to visit our facility and explore the opportunity with our Business Development Lead, Arnie Sathiy. Our system empowers partners to own their own carbon sink and deliver genuinely circular carbon gains.
