Ready to ShipGardenia red pigments, also referred to as natural red dyes, are derived from the gardenia plant and are widely incorporated in different applications. Gardenia red pigment is popular because of its bright red color and, at the same time, its relatively high colorfastness.
The following are the common types of gardenia red pigments:
Aqueous extraction
Aqueous extraction of gardenia red pigments involves using water to obtain the pigments from gardenia fruit. In this procedure, fresh or dried gardenia fruits are boiled in water, leading to the dissolution of the pigment in water. This technique is likely to be more suitable for small-scale extractions or laboratories in their purity research processes.
Organic Solvent Extraction
The organic solvent extraction process uses organic solvents, such as ethanol, acetone, or methanol, to isolate gardenia red pigments from fruits. This technique is likely to be more effective than aqueous extraction because of the higher concentration of pigments extracted; however, it is likely to be less safe, especially when carrying out due to acetone and methanol being toxic and highly flammable, particularly when in close contact with skin. The procedure is usually applied in food, cosmetic, or pharmaceutical industries where gardenia red pigments are used in vibrant color formulations.
Supercritical CO2 Extraction
Supercritical CO2 extraction is a method that uses supercritical carbon dioxide as a solvent to obtain gardenia red pigments. Supercritical CO2 is a carbon dioxide (CO2) subjected to extreme pressure and, at the same time, high temperatures so that it acquires solvent-like characteristics. The process is generally regarded as safe because carbon dioxide does not leave potentially harmful solvent residue on the final product. It is environment-friendly because carbon dioxide is a greenhouse gas. Because of its efficiency and ability to produce high-purity extracts, it is often applied to extract high-value natural compounds and pigments.
Alkaline Hydrolysis
Alkaline hydrolysis is a special dye extracted from gardenia fruit. Mild alkaline solutions are applied to the fruit dye compound to break down the fruit compounds responsible for acid dye protection. This procedure is commonly applied when high gardenia red purity is required.
Chromatography
Chromatography is a laboratory-based technique that separates the compound of a mixture according to its molecular size and affinity towards the stationary and mobile phases used in the experiment. When applied in the extraction of gardenia red pigments, chromatography methods, like high performance liquid chromatography (HPLC) and column chromatography, can achieve significant separation and purification of gardenia red pigments. The technique is largely applied because of the high precision and purification of the pigment extracts.

Gardenia red pigment is a natural colorant obtained from gardenia fruit, and it is valued for its property to impart bright red color to a variety of applications. This pigment is classified as an antonin, a water-soluble red pigment obtained from different species of the gardenia plant. It bears excellent stability under different conditions, such as pH, temperature, and light. Because of this, it can be used in multiple industries, from food to cosmetics.
Color
Gardenia red pigment has a vibrant crimson to ruby red color when dissolved in the medium. The color intensity depends on the concentration of the pigment and the pH of the medium. When in acidic conditions, the color is more intense. On the other hand, its alkaline state makes it dull, shifting toward reddish-brown. This color variability property makes the pigment useful for achieving the desired aesthetic in various formulations.
Stability and Shelf Life
Gardenia red pigments are well known to be very stable, especially when they are stored in cool and dark places. It enjoys this stability due to its affinity to a natural medium apart from synthetic dyes that tend to degrade or lose their intensity over time. When exposed to light, heat, or air, the pigment is likely to gradually lose its intensity. However, it is still more color-stable than synthetic dyes in acidic conditions. Organic dyes gardenia pigments have a shelf life of abrasion resistance and dye fixation to textiles of about 2 years.
