What is Gardenia Yellow Pigment?

Gardenia, also known as Mountain Gardenia, Yellow Gardenia, White Toad Flower, Yuetao, Mudan, and Shizi, is an evergreen shrub of the Rubiaceae family. The extracted pigment comes from the medicinal fruits of Gardenia jasminoides Ellis, a plant of the Rubiaceae family, and various plants of the same genus. Its shape is oval or oval, and it is golden or yellow-red when mature. Chao Li Shizhen’s “Compendium of Materia Medica” has detailed records.
Gardenia Yellow Pigment is It has bright color, non-toxicity, good stability and strong dyeing ability. Anti-cancer health care and other effects.

Gardenia Yellow Pigment Properties

Solubility: easily soluble in polar solvents such as water as well as ethanol, however insoluble in non-polar solvents such as benzene and also fuel. Since the crocin in Gardenia Yellow Pigment is an acidic component, the pigment is a lot more soluble in alkaline option.
Type: yellow things, fluid or pasty and even yellow to orange-yellow crystalline powder.
Spooky characteristics: The liquid remedy of Gardenia Yellow Pigment in the ultraviolet-visible light area has 3 absorption tops: 238, 325, as well as 440 nm, which are the particular absorption peaks of geniposide, chlorogenic acid, crocin as well as crocetin. The liquid solution has a maximum absorption peak at 440 nm.

Fields of Application of Gardenia Yellow Pigment

1. Food sector
Generally, Gardenia Yellow Pigment is mostly used for the coloring of flour products. In recent times, by virtue of its good dyeability to healthy protein and starch, Gardenia Yellow Pigment has actually additionally been extensively used in candy, sweet cash, ice cream as well as various other foods. application. In the comprehensive growth of Gardenia Yellow Pigment, Japan has currently combined Gardenia Yellow Pigment and Gardenia Blue Pigment right into an eco-friendly pigment, and obtained good financial advantages. Gardenia yellow pigment has superb coloring capacity to protein, starch, etc, and can be extensively used in various foods such as cakes, candies, flour, beverages, jelly, biscuits, ice cream and so forth.

2. Printing and also dyeing industry
Xi Deng et al. examined the dyeing of silk tone as well as nylon fabrics by Gardenia Yellow Pigment, as well as defined the adjustment of tone in dyeing thoroughly, which laid the foundation for gardenia yellow pigment in the field of textile dyeing.

3. Cosmetics sector
Liu Xinmin talked about the expediency of using Gardenia Yellow Pigment in cosmetics, thought that Gardenia Yellow Pigment currently had the problems to be made use of in the cosmetics sector, as well as went over the certain problems and extent of its application in the cosmetics industry

4. Pharmaceutical industry.
In addition to pigments that can be colored, Gardenia Yellow Pigment additionally contains a specific amount of saffron acid and geniposide with high clinical value and high cost, such as reconciling blood, advertising blood circulation, removing blood stasis, relieving discomfort, and lowering blood pressure, which can be put on the pharmaceutical industry.

Extraction of Gardenia Yellow Pigment

The extraction methods of natural pigments include solvent extraction, microwave extraction, ultrasonic extraction, supercritical fluid extraction, etc. Currently, most of the extraction methods for Gardenia Yellow Pigment are solvent extraction.

1. Solvent extraction method

1) Raw materials: The content of crocin and geniposide in water gardenia is generally higher than that of mountain gardenia. The content of crocin in the aged gardenia fruit is very little, the color is no longer yellow, and the relative content of gardenia is very high. In addition, the content of crocin in the kernel is higher than that in the whole fruit, and the content of geniposide and chlorogenic acid in the husk is relatively high. Therefore, when extracting Gardenia Yellow Pigment, it is more beneficial to remove the old fruit and extract after dehulling. Improvement in pigment quality.

2) Solvent Crocodin, crocin, crocin and geniposide are all water-soluble polar molecules. The experiment found that alcohol is beneficial to the extraction of crocin and crocin, and water is beneficial to the extraction of geniposide. It is not advisable to use high-concentration ethanol for extraction, otherwise fats, hydrocarbons and more green-stained substances will dissolve with the pigment, and 50% or 60% ethanol is appropriate. Extraction with organic solvents is costly and has certain risks in production, and organic solvents are not conducive to microwave extraction and resin adsorption, which increases the difficulty of the refining process. The extraction process with water is simple, but the extraction time is relatively long, and the extracted pigment impurities are many. If hot water is used for extraction, protease and amylase can be added in the process to promote the dissolution of pigments. The oil content affects the efficiency of pigment extraction, and pre-degreasing before extracting pigment is beneficial to pigment leaching. Acid-added solvents can improve the solubility of pigments, but reduce their stability.

3) Solid-liquid ratio In order to reduce the amount of solvent and the burden of subsequent processes, the dry weight of the fruit (g): the volume of the solvent (ml) is generally 1:6 to 1:12. If the ratio of material to liquid is too large, more energy is consumed for concentration and drying. If the ratio of material to liquid is too small, the extraction of pigments is insufficient, and the filtration of the extraction liquid is also very difficult.

4) Extraction temperature The research shows that 50℃~60℃ is the ideal extraction temperature. If the temperature continues to rise, the increase of the pigment extraction rate is not large, and the high temperature is easy to cause pigment loss. When the extraction temperature is too low, the obtained product is not easy to dry and is easy to deliquescence.

5) Extraction time When water is used as the extraction solvent, especially at room temperature, the extraction time needs more than 12 hours, or even 2 to 3 days. Extraction with organic solvent aqueous solution takes no more than 4 to 5 hours to complete the extraction.

6) Number of extraction stages After the extraction stage is higher than 3 times, the extraction rate of pigments will not increase significantly, and the extraction stage should be selected 2 to 3 times. The five related factors extracted from Gardenia Yellow Pigment were ranked in descending order of their influence on absorbance: fruit crushing particle size, extraction times, extraction temperature, extraction time and solid-liquid ratio, among which fruit crushing degree and extraction times were significant effect factors. The five factors were ranked from large to small for the extraction of pectin: extraction temperature, fruit crushing degree, extraction times, extraction time and solid-liquid ratio, among which fruit crushing and extraction temperature were significant effect factors. After comprehensive optimization of 5 influencing factors, the extraction rate of Gardenia Yellow Pigment can reach 95.13%.

Gardenia Yellow Pigment Assay

1. Ultraviolet Spectrophotometry
In 1987 and 1998, my country promulgated and implemented the national standards for the determination of food additives – Gardenia Yellow Pigment and Gardenia Yellow Pigment in food. In the 1987 standard, the color value and OD value are used as the indicators for the quality evaluation and control of gardenia yellow. The calculation of the color value is based on measuring the absorbance of a certain concentration of gardenia yellow aqueous solution at 440nm, through the formula A1=A*10/G The calculated A1 is the color price. It is not difficult to see that the higher the color price, the better. The lower the last two indicators, the purer the Gardenia Yellow Pigment. Wherein A1 is the absorbance of the powder sample, A is the absorbance of the test solution, G is the weight of the powder sample (g): OD value=A238/A440, OD value less than 04 is qualified. Due to the inaccurate quantification of UV light, this method cannot be effectively used as a quantitative standard for gardenia yellow or crocin.

2. HPLC method
In 1982, pfander et al. used HPLC to measure crocin for the first time. Since then, several cases have been reported abroad to improve and perfect the HPLC method. Wang Chunfang et al. used high performance liquid chromatography to determine the content of crocin, the main pigment component in gardenia japonica and water gardenia, and compared the chromatographic peak purity and spectral consistency of chromatographic peaks. In the 1998 standard, HPLC was used to quantify Gardenia Yellow Pigment with gardeniaside as a reference substance, but there is still no effective quantitative standard for crocin, the main component of gardenia yellow pigment.
