What is Gardenia Yellow?
Gardenia yellow is also known as crocin, commonly known as yellow gardenia, and belongs to the carotenoid series. It is the yellow pigment in gardenia, and its yellow pigment component is crocin, a carotenoid pigment, which is the same as crocin in saffron. The molecular formula is C44H64O24, and the relative molecular mass is 976.97. Gardenia yellow can be used in juice (flavored) beverages, mixed wines, pastry makeup, popsicles, ice cream, puffed foods, jellies, cakes, candies, and canned chestnuts, etc.
Main ingredients
Gardenia yellow pigment is mainly composed of carotenoids crocin and crocetin, as well as flavonoids and chlorogenic acid. Crocin and crocetin are rare water-soluble carotenoids with multiple conjugated double bonds in their molecules. On the one hand, they give gardenia pigment yellow color, and on the other hand, they are also one of the reasons for the instability of gardenia pigment. There are seven crocetin derivatives in gardenia yellow pigment. The chroma and brightness of these seven derivatives are very different, but as the number of glucose genes connected to crocetin increases, the hue of the derivatives decreases, and the color changes from red to yellow.
nature
Orange-yellow crystalline powder with slight odor. Easily soluble in water, it immediately dissolves into a transparent yellow liquid in water. Soluble in ethanol and propylene glycol, insoluble in grease, pH value has almost no effect on color tone. Its color tone is more stable than β-carotene in both acidic (pH value 4~6) and alkaline conditions (pH value 8~11). Especially in alkaline, the yellow color is more vivid, and the absorbance is maximum near the wavelength of 440nm. It has good salt resistance, reduction resistance and microbial resistance. Under neutral or alkaline conditions, gardenia yellow has good light resistance and heat resistance, but at low pH value, it has poor heat resistance and light resistance. Poor, easy to brown. It has a good dyeing effect on protein and starch, that is, it has good coloring power on hydrophilic foods, but it is not stable enough in aqueous solutions. Fading is more pronounced in acidic conditions than in alkaline conditions. It is quite stable to metal ions (such as aluminum, calcium, lead, copper, tin, etc.). Iron ions tend to make gardenia yellow and turn black.
What are the benefits?
⒈Good stability and strong coloring power Gardenia yellow pigment has good resistance to reduction and microorganisms, light resistance and heat resistance. Its color remains basically unchanged within the pH range of 4-11. It is stable to metal ions and has good dyeing effect on starch and protein.
⒉Good safety Gardenia has a history of application in China for thousands of years. People use gardenia to make tea and boil it with malt, three residues and chrysanthemum as a heatstroke prevention beverage. In 1998, the Ministry of Health announced a list of varieties that are both food and medicine, and gardenia was the first. The Sino-Japanese Food Colorant Standard Discussion Meeting was held in Beijing not long ago. The content of this meeting was that China and Japan discussed the unified standards of red yeast rice and gardenia yellow pigment, and then jointly reported to the Joint Expert Committee on Food Additives (JECFA) of the Food and Agriculture Organization of the United Nations and the World Health Organization. After evaluation by the organization, an international product quality technical standard was formed. In this way, gardenia yellow can be widely used worldwide.
⒊ Nutritional Gardenia yellow pigment is mainly composed of crocin and crocetin, which is a rare water-soluble carotenoid that is easily absorbed by the human body and can be converted into vitamin A in the human body. It can supplement the deficiency of human vitamins and is a nutritional colorant.
⒋ Health-care effect Gardenia is a commonly used Chinese medicine. Gardenia yellow has similar effects to gardenia, which can clear away heat and fire, cool blood and promote bile secretion, and lower cholesterol. It has certain health-care functions and is a natural plant pigment that integrates coloring, nutrition, and health-care functions.
Main uses
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, flour, beverages, jellies, biscuits, ice cream, etc.
Silk fabric
The study shows the dyeing performance of natural gardenia yellow on silk fabrics. By changing the dyeing conditions, the silk was dyed by direct dyeing and mordant dyeing, and the optimized dyeing process was obtained through orthogonal test analysis. The results show that gardenia yellow can be directly dyed on silk fabrics, the amount of dye has the greatest impact on the dyeing results, and the dye has good performance improvement. Gardenia yellow is suitable for post-mordant dyeing. Compared with direct dyeing, the color of the fabric dyed by post-mordant dyeing has no obvious change. Except that the sun 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 high medical value and expensive price, such as blood-regulating, blood-activating, fatigue-relieving, pain-relieving, and blood pressure-lowering. It can be applied to the pharmaceutical industry.
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 lower than 80 degrees.
