Gardenia Yellow Powder

What is Gardenia Yellow Powder?

Gardenia Yellow Powder is a natural water-soluble pigment. Easily soluble in alcohol (ethanol), but insoluble in benzene and gasoline. The main advantages of gardenia yellow pigment are (1) intense coloring (2) good safety (3) high nutritional value. It is a yellow pigment extracted from the gardenia fruit of the Rubiaceae plant.

 Yellow pigments exhibit yellow and yellow-like colors because they reflect light in the yellow spectrum to the human eye. But different ingredients show different sources of yellow. Its yellow spectral sources mainly include α-crocin and crocin.

What is the extraction process of Gardenia Yellow Powder?

Improving the quality and purity of gardenia yellow pigment and speeding up the extraction speed are the primary purposes of researching the extraction process of gardenia yellow pigment. There are various methods for extracting and separating gardenia yellow pigment from gardenia, and each has its own advantages and disadvantages. The commonly used methods mainly include organic solvent extraction, enzyme-assisted extraction, microwave-assisted extraction, and ultrasonic-assisted extraction. At present, ultrasonic-assisted extraction and microwave-assisted extraction of gardenia yellow pigment are the most widely used.

Ultrasonic extraction technology is to use the principle of ultrasonic cavitation to accelerate the effective formation of the target.

rate of dissolution. In addition, secondary effects such as mechanical vibration, diffusion, and chemical effects of ultrasonic waves can also accelerate the diffusion effect of extracting components.

Microwave extraction technology utilizes a microwave magnetic field. A technique in which the target substance is selectively heated and separated from the matrix into the extractant. The main features are (1) uniform heating and high thermal efficiency. (2) The microwave extraction technology has a large processing scale and high extraction efficiency. It can save a lot of materials and significantly reduce processing time. (3) The selectivity of microwave extraction is better.

How can I make Gardenia Yellow Powder more stable?

1. Add Antioxidants

For example, the combination of carotenoids and vitamin C can greatly improve the stability of the light.

2. Add stabilizer

The stabilizer's purpose is mainly to reduce the fading speed of the pigment.

3. Add metal chelating agent

The primary purpose is to bind the chelating agent to some metal ions. Thus, metal ions can be effectively absorbed. To achieve the goal of reducing the damage to the pigment; for example, the combination of EDTA-Na can effectively chelate the trace metal ions in the yellow pigment. In this way, the oxidation effect of metal ions on pigments is eliminated.

4. Modification of natural pigments.

Application:

Gardenia yellow pigment is one of the main utilized products in Gardenia. As a pure natural pigment, it has the advantages of non-toxicity, high safety, and certain nutritional value and health care effect. It is also widely used in the coloring industry of pastries, beverages, ice cream, wine, and other foods.

Gardenia yellow pigment also has other carotenoid properties, such as various biological functions. Studies have shown that crocin has carotenoid properties such as antioxidant and free radical elimination.
