Overview

Annatto seeds give bixin (oil-soluble) and norbixin (water-soluble). Bixin is commonly used in fat-rich matrices (butter, margarine, spreads), while norbixin is widely used for cheese and many water-based applications. Aarkay offers oil-soluble, water-soluble and encapsulated grades engineered for improved heat & light stability. :contentReference[oaicite:1]{index=1}

Handling & Regulatory

Store away from direct light and oxygen, in a cool dry place. Use FIFO and request the TDS / COA for batch-specific details and regulatory declarations for your market. Encapsulated grades are available to improve stability where needed. :contentReference[oaicite:6]{index=6}

Technical note:

Select oil- or water-dispersible grades according to your product matrix — oil-soluble grades perform best in fat systems, while water-soluble grades suit aqueous formulations.
