What are the main components of Sorghum Red Color?
The main components of sorghum red pigment are derived from the natural pigments extracted from sorghum shells and other parts. Its main components include geraniol-3-glucoside, cornflower-3-glucoside and other anthocyanin compounds.
These anthocyanins contain phenolic hydroxyl groups in their structure, which give them many characteristics. Under different pH environments, their structures will change, and then they will show different colors. In acidic environments, the color is brighter and more red; in neutral or alkaline environments, the color may darken or change in tone.
The extraction of sorghum red pigment, although there is no precision science and technology in ancient times, must have undergone many attempts and explorations. Or through simple soaking, boiling and other primitive methods, some pigment ingredients are obtained from sorghum shell. As a natural pigment, it is safer than synthetic pigments, and has the unique charm of sorghum itself. It has application potential in many fields such as food and beverages, which can give products a natural color and add unique charm.
What are the applications of Sorghum Red Color?
Sorghum red is bright in color and has applications in many fields. Although "Tiangong Kaiwu" does not elaborate on the specific application scope of sorghum red, it is widely used in terms of ancient classical Chinese style.
In the food industry, sorghum red can be used as a natural coloring agent. For example, in the production of cakes, it can give the cakes a unique red color, add beauty of color and luster, and attract appetite, just like "Zhuyan decoration, fragrant cake color", making the cakes more attractive in appearance. In drinks, such as some special wines, sorghum red can give it a unique color, just like "ripe liquid flowing fragrance", enhancing the visual appeal of the drink.
In the field of printing and dyeing, sorghum red is also useful. It can be used for fabric dyeing. The dyed fabric is warm and moist in color, with a natural and rustic feeling. "Plain silk is red, like danxia". The dyed fabric can create a unique visual effect and show a different charm in clothing production or fabric decoration.
In the field of cosmetics, sorghum red can be used as a natural pigment raw material. It is used in lipstick, blush and other products to add natural color to it, just like "vermilion lips lightly, Xia dyes cheeks", making makeup more natural and healthy, and natural ingredients are more in line with people's pursuit of green and safe cosmetics.
In addition, in terms of drug icing, sorghum red can also play a role, giving the drug a suitable appearance and luster, helping to distinguish different drugs, just like the "red label, the effect is easy to distinguish", which is convenient for patients to identify and use.
What are the precautions in the use of Sorghum Red Color?
In the process of using sorghum red, you should pay attention to the following things:
First, abide by the dosage regulations. Although sorghum red is a natural pigment, it should not be abused wantonly. "Tiangong Kaiwu" cloud: "Everything has a degree, too much is too much." Excessive use, not only can not achieve the expected color enhancement effect, but also cause the food color to be strange, unnatural, and may affect the food flavor. According to the relevant food additive use standards, different food categories have clear restrictions on the amount of sorghum red. For example, in candies, pastries and other categories, the maximum amount used is equal, and it must be strictly followed to ensure food safety and quality.
Second, pay attention to the scope of application. Not all foods are suitable for adding sorghum red. Just as the material selection of "Tiangong Kaiwu" has its own suitability, the scope of application of sorghum red is also defined. It is commonly found in cooked meat products, jellies, beverages and other foods, and in some foods with strict color requirements and need to maintain the primary color, such as clear and transparent drinks, it may not be used, so as not to damage its original characteristics.
Third, pay attention to stability. Sorghum red stability is closely related to the surrounding environment. It is more sensitive to light and heat. Too much light or too high temperature may cause it to fade or discolor. "Tiangong Kaiwu" says that it is often necessary to choose a suitable place for the preservation of utensils, and the same is true of sorghum red. During storage and use, direct light should be avoided, and processing temperature and time should be controlled. Such as food processing, high temperature baking or long-term stewing of food, the use of sorghum red should consider its stability, if necessary, take color protection measures to maintain its color lasting.
Fourth, pay attention to compatibility with other things. Food processing often requires a variety of additives to coordinate. When sorghum red is shared with other pigments and additives, it may interact. Or cause color changes, or affect stability. All kinds of process cooperation in "Tiangong Kaiwu" pay attention to complementing each other, and the same is true here. Before use, it needs to be tested to clarify its compatibility characteristics, to ensure that there are no adverse reactions when mixed, and to achieve the desired effect.
What are the advantages of Sorghum Red Color compared to other similar products?
The color of sorghum red, compared with other similar products, has three advantages.
First, the color is fresh and stable. Sorghum red is collected from sorghum, and the color is bright and warm, bright but not vulgar, and the longer it passes, the more mellow the color, unlike other colors that are easy to fade. The ancient dyer said: "Sorghum red, the color does not change over time, and it lasts for a long time." It is used to dye silk paintings, and it can keep the color for a long time, just like the beginning.
Second, the source is natural and pure. Sorghum red is a natural pigment, taken from natural sorghum, without the risk of chemical additions. Compared with other synthetic colors, it is non-irritating to the human skin, harmless to the body, and blends with nature, which is in line with the way of the ancients "Fa Tian Gui Zhen". For example, the "Compendium of Materia Medica" also praises the safe use of natural things.
Third, it is widely used and suitable. Sorghum red can be applied in various fields such as food, medicine, and painting. For food, it can add the color of food and increase people's appetite; for medicine, it may have the effect of health care; for painting, it can become the color rhyme of wonderful paintings. Its nature is mild, suitable for all kinds of materials, unlike other colors or limited. Ancient craftsmen mostly chose sorghum red as the top choice, because of its good adaptability, it can meet various needs.
Therefore, sorghum red is more similar to other products, with stable color, pure source, and wide use, and should be valued by everyone.
What are the storage conditions for Sorghum Red Color?
Sorghum red pigment is taken from sorghum, which is bright and unique. Its storage conditions are quite important, and it is related to the quality and effect of the pigment.
Sorghum red pigment should be placed in a cool place. In a cool place, the temperature is relatively constant, and there is no disturbance of high temperature. High temperature can easily cause the thermal movement of pigment molecules to intensify, causing its structure to be damaged, which in turn causes color attenuation and stability. If exposed to the hot summer sun, the color of the pigment will be light and easy to deteriorate in a few days.
Dry environment is also an important rule for storage. Moisture can easily make the pigment absorb moisture and cause deliquescence. After deliquescence, it may agglomerate or mildew, which seriously damages its quality. If it is in the rainy season in the south, the air humidity is high, and if the sorghum red pigment is not properly stored in a dry place, it will be susceptible to moisture.
Sealed storage is indispensable. Excessive contact with the air, the pigment is easy to oxidize. During the oxidation process, the pigment composition changes, the color gradually darkens, and there may be a peculiar smell. Therefore, using a sealed container can reduce the influence of air. For example, storing it in a glass bottle and sealing the mouth of the bottle can protect the pigment.
To sum up, if you want to store sorghum red pigment well, you should choose a cool, dry place and seal it. In this way, you can keep its color fresh and good quality, and get the best effect when using it.
