The basic nature of Gardenia Yellow

Gardenia Yellow orange powder, soluble in water, transparent solution, no peculiar smell; Insoluble in anhydrous ethanol, ethyl ether and other organic solvents. PH almost has no effect on tone, Mangiferin and under alkaline and neutral conditions, it has good stability of light, heat and metal ions (but has great influence on tin and iron ions). Good reducibility and microbial resistance, stable staining of protein and starch.
Ginkgo Biloba Extract, also known as cape jasmine, is a carotenoid series. The yellow pigment in the fruit of Madder gardenia is mainly gardenin. The chromogenic components are crocin and Crocetin. Gardenia yellow can be used as food additive in fruit juice (flavor) beverage, wine preparation, Bitter Melon Extract cake makeup, Popsicle, ice cream, puffed food, jelly, bread, candy and canned chestnut, etc.

Gardenia Yellow trends

Gardenia Yellow is used for food coloring in the United States, Britain, Canada, Norway and Luxembourg, especially in Japan. Gardenia yellow has a wide range of applications in Japan, such as egg rolls, Mangiferin biscuits, flour, candy, preserves, ice cream, popsicles, fruit dew, fresh orange juice, fresh orange water and jelly, etc. China is the world's largest exporter of gardenia yellow, Flax lignans mainly exported to Japa. With the progress of science and technology and the continuous efforts of scientific researchers, the product quality is gradually improved, and its development prospects are also very optimistic.
The extraction methods of gardenia yellow include solvent extraction Mixed Tocopherols Oil and microwave extraction.

Gardenia Yellow is prepared by solvent extraction

Technology: Gardenia Yellow fruit, shelled grinding, solvent extraction degrease, organic solvent extraction, concentration, refining, drying, finished products. Xanthocyanin, Xanthic acid that gardenia rectification are water-soluble polar molecules, and there are many kinds of extraction agents. Studies have shown that alcohol is beneficial to the extraction of anthocyanin and anthocyanin acid, but it is not suitable to extract with high concentration of ethanol, otherwise the fat, hydrocarbon and many green substances will be dissolved with pigment, Mangiferin and 50% ethanol and 60% ethanol are suitable. Organic solvent extraction, high cost, production also has a certain risk, and organic solvent is not conducive to microwave extraction and resin adsorption, increasing the difficulty of refining process. The extraction process with water is simple, but the extraction time is relatively long, and there are many pigment impurities extracted. If Flax lignans is extracted with hot water, protease and amylase can be added in the process to promote pigment dissolution. The oil content affects the efficiency of pigment extraction, and pre-degreasing before pigment extraction is beneficial to pigment extraction. Acid solvent can improve the solubility of pigment, but reduce its stability. 50-60℃ is the ideal extraction temperature. When water is used as the extraction solvent, especially at room temperature, the extraction time is more than 12h, or even 2-3 days, and the extraction time is not more than 4-5h. Mixed Tocopherols Oil is advisable to raise the series 2 or 3 times.

The preparation method of Gardenia Yellow is microwave extraction

Microwave extraction

The Gardenia Yellow extraction power was 210w, the extraction time was changed by extracting with 50% ethanol and water solution at the time of 80s twice, the solid-liquid ratio was 1:12, Indole-3-Carbinol and the extraction rate of pigment was 98.24%. The traditional method was used to extract 60% ethanol solution at 5℃ for 2 times, each time 2h. The extraction times and ratio of solid to liquid were the same as that of microwave extraction. However, 3-Indolylcarbinol the extraction rate of pigment was lower than that of microwave extraction (92.1%).

Compared with traditional solvent extraction, 3,3'-Diindolylmethane microwave extraction has the advantages of less time consuming and higher efficiency.

What are the main ingredients of Gardenia Yellow

It's a carotenoid, which you can think of as a nutrient. Gardenia Yellow is also a rare water-soluble carotene and is resistant to cooking, making it more versatile.

Of course, natural pigments often have weaknesses, such as their relative ease of fading in acidic environments or dissolved states.

Gardenia has a long history of folk application in China. Barley Grass Powder was used as a fabric dye as early as the Qin and Han Dynasties.

In CCTV's "Flavor Chinese Year," a local chongqing food called Huang Po (Capsicum Oleoresin) is made from glutinous rice and japonica rice, the yellow of which also comes from gardenia.

Now gardenia belongs to the medicinal food substance, gardenia yellow as pigment can be used in flour products, cakes, cookies, candy and more than 20 kinds of food.

For example, you can see gardenia yellow in some of the ingredients for instant noodles, which is mainly used in the bread to give it a golden color.

Flax lignans are generally considered more appetizing, and while they can be 'coloured' by frying, the process produces large amounts of acrylamide.

Can the noodles that contain Gardenia Yellow give a child to eat?

Gardenia Yellow is actually a natural substance

Because it appears as an "additive", it makes parents suspicious.

Food products often use pigments to enhance their appearance and appetite. More common yellow pigments are Mangiferin and gardenia yellow.

The names of these two pigments are very "natural", but in fact the former is a chemical synthetic pigment and the latter is a natural pigment.

Although both are equally safe, I believe most Flax lignans are more comfortable with natural gardenia.

Gardenia is a shrub widely distributed in central, south and southwest China. People love its floral fragrance, so it is a common garden plant.

Wild gardenia is also called mountain and yellow gardenia, but it's actually the same species as garden gardenia.

Gardenia flowering every summer, autumn fruit mature, dry fruit extraction with the natural pigment gardenia yellow.

At present, China is the main producer of gardenia yellow. N-Acetylneuraminic Acid products are exported to Europe, America and Japan.

What are the influencing factors of gardenia yellow

In the UV visible region, there are three absorption peaks of gardenia yellow in aqueous solution: 238nm, 325nm and 440nm, which are the characteristic absorption peaks of geniposide, chlorogenic acid, Flax lignans and crocetin respectively.

Food Colour Crocus Sativus solution is orange yellow at pH 1 ~ 7 and bright yellow at pH 8 ~ 12. The stability of the pigment was poor under acidic conditions, but good under neutral and alkaline conditions. Similar to other carotenoids, gardenia yellow had poor sunlight tolerance. Except for Fe and Cu, common metal ions had no effect on Gardenia yellow.

When gardenia yellow solution coexists with oxidant, Mangiferin will fade due to oxidation. Therefore, if gardenia yellow is used in food, it is necessary to avoid contact with oxidants during processing and storage, so as to delay or reduce the fading of gardenia yellow.

In the food system with Beet Root Powder as dye, ascorbic acid and sodium isoascorbate can significantly delay the color fading. Therefore, on the premise of not affecting the flavor and other quality indexes of the product, proper amount of antioxidant can be added to prevent or delay the fading of gardenia yellow.

Main uses of gardenia yellow(2)

Compared with direct dyeing, the color of the Bitter Melon Extract with post mordant has no obvious change. Except the light fastness is no more than grade 3, the other fastness is basically above grade 4, which is more reduced.

Pharmaceutical industry(Gardenia Yellow)

In addition to Capsicum Oleoresin components that can be colored, the yellow pigment also contains saffron acid with high medical value and high price, such as blood harmonizing, blood activating, fatigue eliminating, pain relieving and N-Acetylneuraminic Acid pressure reducing, which can be applied to the pharmaceutical industry.

Main uses of gardenia yellow(1)

Food industry

The 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 residual rate of pigment is more than 85% at 80 ℃ for 120 minutes. In the range of visible light (40lun-700nln), the light irradiation is stable, but the light irradiation is unstable in the range of 250nm-390nm. Therefore, mast Mangiferin can be used as antioxidant and colorant in food industry.

Mast yellow pigment has excellent dyeing ability to protein, starch and so on. It can be widely used in pastry, candy, flour, beverage, Flax lignans, biscuit, ice cream and other foods.

Silk fabric

The results show that natural gardenia yellow can dye silk fabrics. By changing the dyeing conditions, direct dyeing and mordant dyeing were used to dye silk. The optimal dyeing process was obtained by orthogonal test analysis. The results show that gardenia yellow can be directly dyed on silk fabrics, and the amount of dyes has the greatest influence on the dyeing results, Ginkgo Biloba Extract and the dye has better lifting performance. Gardenia yellow is suitable for mordant dyeing.

The properties of gardenia yellow

Orange yellow crystalline powder, slightly smelly. Synephrine Hcl is easily soluble in water and immediately dissolves into a transparent yellow liquid. It is soluble in ethanol and propylene glycol, but insoluble in oil. PH value has little effect on hue. Its hue is more stable than β - carotene in acid (pH 4 ~ 6) and alkaline (pH 8 ~ 11), especially in alkaline medium. Its color is more bright, and its absorbance is maximum near 440nm. Under neutral or alkaline conditions, Pine Bark Extract has good light and heat resistance, but it has poor heat resistance and light resistance at low pH value, and is easy to browning. It has good dyeing effect on protein and starch, that is, Ginkgo Biloba Extract has good coloring power for hydrophilic food, but it is not stable in aqueous solution. The discoloration is more obvious in acid than in alkali. It is stable to metal ions (such as aluminum, calcium, lead, copper, tin, etc.), and iron ions tend to make Gardenia Yellow and black.

The structure and classification of flash Ligans(1)

Mangiferin exist in plants, belonging to a kind of phytoestrogen, which has the function of scavenging free radicals and antioxidation. Lignans are also found in grains (such as rye, wheat, oats, Gardenia Yellow, etc.), soybeans and cruciferous plants (such as broccoli) and some fruits (such as strawberries). Lignans can bind estrogen receptors and interfere with cancer promoting effect. Therefore, Sweet Potato Powder may have preventive and therapeutic effects on breast cancer, prostate cancer and colon cancer.

Lignans are a kind of natural components which are polymerized by phenylpropanoid bimolecular polymerization. There are four monomers of lignans: ① cinnamic acid and occasionally cinnamaldehyde. ② N-Acetylneuraminic Acid. ③ Propylene benzene. ④ Allyl benzene.

Phyllanthin

Classification basis: according to the basic carbon frame and condensation of lignans.
