Product Overview
Gardenia Blue Powder is a premium, water-soluble natural colorant produced through advanced bio-engineering technology from the fruit of Gardenia jasminoides. Renowned for its deep, vibrant blue hue and excellent stability, it serves as a safe, non-toxic alternative to synthetic dyes in the food, beverage, nutraceutical, and cosmetic industries.
Approved as a food additive in China since 1990, Gardenia Blue has become an essential ingredient for formulators seeking clean-label, plant-derived coloring solutions. Its unique ability to blend with natural yellow and red pigments allows manufacturers to create a wide spectrum of customizable green, purple, and teal shades with superior acid resistance compared to traditional chlorophyll-based greens.

Production Process & Quality Assurance
Sourced from high-quality gardenia fruits cultivated in China’s optimal growing regions, our Gardenia Blue is extracted using state-of-the-art biotechnology. The process involves controlled enzymatic hydrolysis followed by purification to concentrate the iridoid-derived blue pigments (primarily genipin derivatives). Rigorous in-house and third-party testing (SGS, Eurofins, Pony) guarantees batch-to-batch consistency, purity, and regulatory compliance.
Stability Profile
- pH Stability: Maintains excellent color integrity between pH 4.5 and 8.0, making it ideal for acidic beverages and functional foods.
- Heat Stability: Best added after thermal processing when the solution has cooled to 60°C or below. Immediate further cooling after addition preserves maximum color intensity.
- Light Stability: Naturally sensitive to UV exposure; color retention is significantly enhanced when formulated with antioxidants such as sodium ascorbate or mixed with other natural pigments.
