β-Cryptoxanthin

Updated: 2026-09-11

Overview

β-Cryptoxanthin is a naturally occurring carotenoid found in fruits such as oranges, papayas, and persimmons, as well as in some vegetables. It is classified as a provitamin A carotenoid, meaning it can be converted into vitamin A in the body. This compound is valued for its dual role as a pigment and a bioactive nutrient, contributing to both color and health benefits in various applications. In addition to its provitamin A activity, β-Cryptoxanthin exhibits strong antioxidant properties, helping to neutralize free radicals and reduce oxidative stress. Its stability and bioavailability make it a popular ingredient in functional foods, supplements, and cosmetic formulations.

Physical and Chemical Properties

β-Cryptoxanthin is an orange-red crystalline powder with a molecular weight of 552.85 g/mol. It has a melting point of 169-170°C and is soluble in organic solvents like ethanol and acetone but insoluble in water. The compound is sensitive to light, heat, and oxygen, requiring careful storage to maintain its stability and efficacy. Its chemical structure includes a hydroxyl group, which differentiates it from other carotenoids like β-carotene. This structural feature influences its solubility and interaction with other molecules, making it suitable for specific industrial applications where solubility in fats or organic solvents is required.

Main Applications

β-Cryptoxanthin is widely used as a natural colorant in the food industry, particularly in beverages, dairy products, and confectionery. Its vibrant orange hue and health benefits make it a preferred alternative to synthetic dyes. In dietary supplements, it is included for its provitamin A and antioxidant properties, supporting vision, immune function, and skin health. The cosmetic industry also utilizes β-Cryptoxanthin in skincare products for its antioxidant effects, which help protect the skin from environmental damage. Additionally, it is incorporated into animal feed to enhance the nutritional profile and coloration of poultry and fish products.

Safety and Storage

β-Cryptoxanthin is generally recognized as safe (GRAS) for use in food and supplements. However, proper handling is essential to avoid inhalation or eye contact, as it may cause irritation. Storage conditions should include protection from light, moisture, and oxygen to prevent degradation. For industrial use, it is often encapsulated or blended with stabilizers to extend shelf life. Regulatory compliance with standards set by the FDA, EFSA, or other relevant authorities should be confirmed during procurement to ensure product safety and quality.

B2B Procurement Guide

When sourcing β-Cryptoxanthin, buyers should prioritize suppliers who provide certificates of analysis (CoA) detailing purity, origin (natural or synthetic), and contaminant levels. Price varies based on purity, with higher grades (≥90%) commanding premium rates. Bulk purchases may offer cost advantages, but storage capacity and shelf life should be considered. Procurement professionals should also evaluate supplier reliability, lead times, and compliance with industry regulations. Sustainable sourcing practices, such as extraction from non-GMO or organic raw materials, may appeal to environmentally conscious buyers.
