Frequently Asked Questions

Yes, all our food colorants are rigorously tested and comply with international safety standards including FDA, EFSA, and WHO guidelines. We conduct comprehensive safety assessments including toxicological studies, allergen screening, and heavy metals analysis to ensure consumer safety.

Natural colorants are derived from natural sources like fruits, vegetables, spices, and algae. They offer clean-label appeal but may have limitations in stability and color intensity. Synthetic colorants are chemically synthesized, offering superior stability, consistency, and vibrant colors, making them ideal for applications requiring specific performance characteristics.

Consider factors like pH stability, heat resistance, light stability, solubility requirements, and regulatory compliance. For water-based products, choose water-soluble colorants. For oil-based applications, lake colors are ideal. Our technical team can provide personalized recommendations based on your specific formulation and requirements.

Lake colors are oil-dispersible pigments made by precipitating water-soluble dyes onto an insoluble substrate. They're perfect for fat-based applications like chocolate, confectionery coatings, and oil-based products. Lake colors provide excellent stability in high-fat environments and don't migrate or bleed in oil-based systems.

Store colorants in cool, dry places away from direct sunlight and heat sources. Keep containers tightly sealed to prevent moisture absorption. Most colorants have a shelf life of 2-3 years when stored properly. Avoid storing near strong odors as colorants can absorb them. Check individual product specifications for specific storage requirements.
