β-Carotene
High Stability: β-Carotene is recognized as one of the most stable natural pigments, demonstrating strong resistance to degradation under standard storage conditions when shielded from light and air.
Antioxidant and Nutritional Functions: It functions as an effective antioxidant and serves as a precursor to vitamin A, contributing to immune support and visual health.
Broad Industrial Utility: Owing to its safety profile and nutritional value, it finds extensive application as a coloring and functional ingredient in foods, cosmetics, and dietary supplements.
Solubility Characteristics: The compound is fat-soluble and demonstrates good compatibility with non-polar solvents such as hexane and chloroform, facilitating its use in lipid-based product formulations.
β-Carotene, a naturally occurring carotenoid, exhibits high stability as a fat-soluble pigment. It typically presents as an orange-yellow crystalline powder or lustrous rhombohedral crystals, primarily sourced from green plants and yellow-orange fruits. Its solutions display orange-yellow to yellow coloration in diluted form, with color intensity increasing proportionally to concentration. The hue may exhibit slight reddish variations depending on solvent polarity. Valued for its antioxidant capacity and role as a vitamin A precursor, β-carotene finds broad application in food products, cosmetics, and nutritional supplements.
