Green Spring uses automated machines to remove unfresh gardenias and thoroughly clean the gardenias. Our technicians then deeply process the gardenias to extract gardenia yellow.
The fruits of the Rubiaceae plant gardenia are peeled, crushed, and made into powder. The powder is extracted with water or ethanol-water solution, and refined to obtain a paste or further refined into gardenia yellow pigment.
The ethanol solution extraction method is as follows:
Crush the ripe gardenia fruit and add CaCO3. Use 20% ethanol solution to extract at 75 ℃ for 4h, change the extract twice in the middle, filter, the filtrate flows through porous adsorption resin, elute the resin with 25% ethanol solution, then use 50% ethanol solution to elute the resin and collect the eluent, reduce pressure to concentrate the eluent, dry to obtain the finished pigment, or vacuum film evaporation and concentration, spray drying.
SECURITY
The green spring's gardenia yellow raw material uses fresh gardenia. Green Spring Company adopts a "company+farmer" model and signs contracts with upstream producers of gardenia. Xi'an Green Spring provides high-quality gardenia seeds and other raw materials as well as advanced planting techniques to farmers. Under the guidance of our company's professionals, farmers are responsible for planting and harvesting vegetables. The company purchases gardenia produced by farmers according to regulations.
Through the "company+farmer" model, we have ensured the food safety of gardenia yellow raw materials, making our production and processing processes more closely linked. We strictly require farmers to plant gardenia to ensure that the raw material for gardenia yellow is a green and pollution-free product.
APPLICATION
Usage
Add the required amount of pigment to an appropriate amount of water or dilute ethanol, dilute and stir evenly, then add this yellow solution to the product to be dyed and stir evenly. The operating temperature should be below 80 degrees.
Food Industry
Gardenia yellow pigment can inhibit the oxidation of 80% linoleic acid, so it can be used as an antioxidant in food processing; it has good heat resistance, and the pigment residual rate is above 85% under the conditions of 80 ℃ and 120 minutes; it is stable to light irradiation within the visible light range (40lun -700nln), but unstable to light irradiation within the wavelength range of 250nm-390nm. Therefore, gardenia yellow pigment can be used as an antioxidant and colorant in the food industry.
Gardenia yellow pigment has excellent dyeing ability for protein, starch, etc., and can be widely used in various foods such as cakes, candies, beverages, jellies, biscuits, ice cream, etc.
Textile Industry
The study shows the dyeing performance of natural gardenia yellow on silk fabrics. By changing the dyeing conditions, direct dyeing and mordant dyeing methods were used to dye silk, and the optimized dyeing process was obtained through orthogonal test analysis. The results show that gardenia yellow can directly dye silk fabrics, the amount of dye has the greatest impact on the dyeing results, and the dye has good performance improvement. When gardenia yellow is mordant dyed, it is suitable to use post-mordant dyeing. Compared with direct dyeing, the color of the fabric after post-mordant dyeing does not change significantly. Except that the light fastness does not exceed level 3, the other fastnesses are basically above level 4, which is more restored.
Pharmaceutical Industry
In addition to containing pigment components for coloring, gardenia yellow pigment also contains a certain amount of crocetin, which has extremely high medical value and is expensive, such as harmonizing blood, promoting blood circulation, eliminating fatigue, relieving pain, and lowering blood pressure. It can be applied to the pharmaceutical industry.
