What is Beetroot Red?

Beetroot Red is a natural pigment made from edible red beetroot via removal, separation, focus and drying out. The major element is beet anthocyanin, as well as beetroot red is a red-purple to dark purple fluid, powder, and quickly soluble. Water and liquid remedies are red to purple-red with intense shade. Beetroot Red has bright color, consistent coloring, no strange scent, as well as has great coloring function. Beet red pigment is widely used in the coloring of drinks, gelato, some alcohol, sweet, cakes, meat products as well as various other foods. The coloring building of food is excellent, and considering that the pH value of most foods is in between 3.0 and 7.0, as well as its color does not change in this pH worth variety, when Beetroot Red is made use of as a food tinting agent, the shade of the food will not change.

will be affected by pH. Satisfactory dyeing and color lasting results can be obtained with Beetroot Red in the production of low water activity foods. Compared with other colorants, beetroot is relatively stable during food processing and storage. Beetroot Red can give food the bright red color of bayberry or rose. Vitamin C is slightly stable in the presence of polysaccharides and prevents fading in the presence of polysaccharides. It is used in cold fruits that are not affected by heat and light, especially yogurt, milk and strawberry drinks, soft ice and any food. In the study of removing nitrite in sausage with beet red pigment and chitosan oligosaccharide, it was found that chitosan has a good water retention ability, but the ability to remove nicotine nitrate is relatively hot. Beet red pigment has a good ability to remove nitrite. Therefore, in the process of producing sausages, the general amount of chitosan is reduced, and beet red pigment is used to supplement it, which can be used as a coloring agent for sausages and as nitrous acid. Salt scavenger.

Beetroot Red App

Beetroot Red is an ideal natural red pigment resource because of its bright and natural color, no toxic side effects, no special odor, and certain health care functions, so it is widely used in food, health products, medicine, cosmetics and other fields.

1. Food coloring
Beetroot Red is a natural pigment extracted from edible vegetables – red beet, so it is non-toxic, no side effects, bright in color and contains nutrients necessary for human body building, metabolism and growth and development, so it is widely used in various beverages, fruit flavors Powder, juice road, soft drink, candy, pastry, sandwich, ice cream, canned food, fruit juice concentrate, ice cream, jelly, sausage food coloring, and increase the beautiful appearance of food and improve the nutritional value of food.

2. Application of medical and health products
The main antioxidant part of Beetroot Red is the red part, and beta red glucoside. After eating thorn pear fruits containing betalain, lipid damage caused by peroxidative stress can be significantly reduced, and the antioxidant level of the human body can be improved; in vitro erythrocytes cultured in betalain solution for a period of time can also be significantly delayed due to the oxidant cumene. Hemolysis by cumene hydroperoxide. Secondly, beetroot contains betaine, which has a certain curative effect on liver diseases (such as chronic hepatitis, liver cirrhosis, toxic hepatitis, metabolic liver disease and liver dysfunction caused by biliary tract disease, etc.). Therefore, beet red pigment can not only beautify the appearance of medicines for special populations and is conducive to taking them; in terms of distinguishing medicines, beet red pigment can also be used instead of synthetic pigments to distinguish medicines well. Treatment also has an indelible role. In addition, beetroot has a significant inhibitory effect on skin cancer and lung cancer in mice. Because the beet red pigment has the above functions, it can be used in the research and development of medicines and health products.

3. Application in cosmetics
The production of many cosmetics requires the addition of pigments, such as lipsticks, shampoos, hair dyes, etc. Since most of the pigments added in the domestic cosmetic production process are synthetic pigments, some people with sensitive skin will experience allergic symptoms during use. For them, natural pigment is undoubtedly a good choice; and beetroot is a natural pigment, non-toxic and harmless, and also has medical and health care functions, so it is used in the production of colored cosmetics and anti-aging cosmetics, and has a large develop potential.

4. Other applications
In addition to being used in food coloring, medicine, cosmetics, and health care products, Beetroot Red can also be used for wool dyeing in recent studies. Wool dyeing should be carried out under low temperature and strong acid conditions. After dyeing, the quality of the wool has been significantly improved, and the Beetroot Red is a natural pigment with bright color, non-toxic and harmless, and will not pollute the environment, so the application prospect of beet red pigment as a coloring dye is also very broad. In order to improve the comprehensive utilization value of sugar beet, the extracted sugar beet residue can be used for alcohol production, fermentation as compound fertilizer, animal feed, etc.

Beetroot Red Extraction and Purification

1. Traditional extraction method: The traditional method for extracting Beetroot Red is solid-liquid extraction, and the extraction methods include immersion, soaking and Soxhlet extraction. Solid-liquid extraction technology: The components in the solid mixture are separated by a solvent, so that the soluble components in the solid matter are dissolved and entered into the liquid phase, and then the solution is separated from the insoluble solid matter. Beetroot Red is generally dissolved in water, but if a certain proportion of methanol or ethanol is added, the beet red pigment in red beet can be completely extracted. In general, when extracting red beet pigment, first fully soak the red beet in a closed container with pure water or a solvent containing methanol, etc., and then stir it so that more beet red pigment enters the extract, and finally the solid is filtered by filtration. liquid separation. Although the traditional method for extracting Beetroot Red is time-consuming, it is very useful for extracting some thermally unstable substances because it operates completely at room temperature and does not require heat treatment.

2. New technology of Beetroot Red pigment extraction The new extraction techniques of Beetroot Red include γ-ray method, sonication method, ultrasonic-assisted technique, membrane treatment method, and high-voltage pulsed electric field method, etc. These techniques can be carried out at lower temperature, so they can be well maintained. biological activity and higher extraction efficiency.

1) Gamma Irradiation: The Beetroot Red is extracted from red beet by solid-liquid extraction. If it is pretreated by gamma rays, the extraction efficiency will be increased. The radiation dose is in the range of 2.5~10 k Gy. The extraction efficiency gradually increased with the increase of the dosage. Gamma rays improve the extraction of pigments mainly because rays can change the internal structure of plant tissues and promote the rupture of cell walls. Studies have shown that treating fresh Beetroot Red with low doses (1~2 kGy) of γ-rays can cause biochemical changes in the interior of red beet tissue and cell walls. Irradiated to study the biochemical properties of red beet and the stability of Beetroot Red . The results showed that there was no significant difference in the yield of extracted beet red pigment between the γ-ray treatment and the control, but if the radiation dose exceeded 10kGy, it would cause sugar beets. The red pigment structure changes, so the recommended dose of γ-ray does not exceed 10kGy.

2) High-voltage pulsed electric field: Because it is a non-thermal processing technology, the use of high-voltage pulsed electric field to electroporate cells can change the permeability of the cell wall and cell membrane, and make the cell contents seep out to achieve non-thermal sterilization. Effect. The high-voltage pulsed electric field is processed by applying short pulses of high voltage to the sample between the two electrodes for many times. Due to the advantages of short treatment time, small pollution, inhibition of microorganisms, passivation of enzymes and non-heating treatment, it can be better. to maintain the nutritional properties and quality of food.

3) Ultrasound-assisted extraction technology (Ultrasound-assisted extraction): Ultrasound-assisted extraction technology is a low-cost, environmentally friendly and fast extraction technology, which has broad prospects in the extraction of thermally unstable active substances. Since the ultrasonic wave can generate and transmit powerful energy, it can promote the better penetration of the solvent into each part of the sample matrix, increase the contact area between the solid phase and the liquid phase, and make the solute disperse into the solvent more quickly. It was found that ultrasonic wave significantly improved the extraction efficiency of Beetroot Red . Using ethanol and water 1:1, ultrasonic power of 80 W, and extraction time of 3 h, the yield of Beetroot Red increased by 8%.

4) Supercritical extraction technology (Supercritical Extraction): use supercritical CO2 as a solvent, select appropriate temperature and pressure, and use the excellent solubility of CO2 to dissolve the content of solid matter to achieve the purpose of separating specific active ingredients . When the Beetroot Red is exuded from the cells, the pigment will come into contact with various enzymes, and the peroxidase and polyphenol oxidase will quickly degrade the pigment, causing the quality of the Beetroot Red to decline. Studies have shown that when using high pressure CO2 to extract red beet juice, it was found that under the condition of 55 ℃ and 60 min, 37.5 MPa can reduce the activity of peroxidase by 86%, and 22.5 MPa can reduce the activity of polyphenol oxidase. The activity of the enzyme was reduced by 95%, and the change in enzyme activity was more sensitive to pressure than due to the critical state of CO2.

5) Membrane Processing: Membrane processing technology can achieve the purpose of enriching biologically active substances without heating. Different target compounds are extracted, purified, and concentrated, and so are the types of membrane treatments used, such as electrodialysis, microfiltration, ultrafiltration, reverse osmosis, electrodialysis, membrane distillation, and steam osmosis. ] Using ultra-fine filtration and reverse osmosis to purify and concentrate the Beetroot Red in red beet, it was found that the use of pectinase treatment could reduce the viscosity of the juice and improve the efficiency of pre-filtration, and found that adding invertase and pectinase, after Ultrafiltration can increase the yield of beet red pigment by a factor of three. The choice of different membrane types is the key to recovering the beet red pigment. Studies have shown that anisotropic membranes are the best system for the separation of Beetroot Red , increasing the recovery of Beetroot Red and reducing the level of soluble solids.

Physical and Chemical Properties of Beetroot Red

1. Solubility
Beetroot Red is red-purple or dark purple liquid, lump or powder, or paste, with bright color:
Easily soluble in water and water-containing solvents, it is a water-soluble pigment, insoluble in acetic acid, propylene glycol, and insoluble in organic solvents such as absolute ethanol, glycerol, acetone, chloroform, oil, and ether.

2. Acid-base environment reaction characteristics
Beetroot Red is red or dark purple liquid, block or powder or paste with bright color, but its color tone is affected by pH value. When pH is 3.0-7.0, it is red and relatively stable; when pH is 4.0-5.0, it is the most stable. Stable; when pH<4.0 and pH>7.0, the color turns from red to purple; when pH>10.0, the betachromin in beet red pigment is converted into betaaxanthin, and the color of the solution turns yellow rapidly. This shows that the beet red pigment is relatively stable under acidic and neutral conditions. Since the pH value of most foods is between 3.0 and 7.0, and the color of betanin does not change within this pH range, the color of food containing betanin is generally not affected by pH value.

3. The effect of light on pigment stability
Natural light will affect the stability of the Beetroot Red aqueous solution, and the color will fade to yellow when placed under natural light for a long time. However, natural light has little effect on the 50% ethanol solution of beet red pigment, and ultraviolet light has little effect on the stability of beet red pigment.

4. The effect of heat on pigment stability
The heat stability of Beetroot Red was the best at pH 4.5, while the heat stability of beet red was generally poor, and the heat resistance decreased with the increase of temperature. In order to reduce the loss of pigment and achieve sufficient extraction effect during leaching, it is generally carried out at about 25°C.

5. The effect of metal ions on pigment stability
Metal ions have a certain influence on the stability of betalains. Excessive Fe3+, Cu2+, Mn2+, Ca2+, etc. can promote the degradation of betalains and reduce the hue of Beetroot Red. Therefore, in the application, if necessary, an appropriate metal chelating agent is added to remove metal ions.

6. The effect of food additives on pigment stability
The oxidation resistance test of Beetroot Red was carried out with H2O2. With the increase of H2O2 addition and the prolongation of action time, the loss rate of beet red pigment accelerated, indicating that beet red pigment was easily oxidized. The reduction resistance experiment shows that the high concentration of reducing agent has a greater impact on the beet red pigment, and it is concluded that the beet red pigment has poor reduction resistance, so contact with oxidants and reducing agents should be avoided during production and application. In addition, additives such as glucose, citric acid and sodium benzoate have little effect on the stability and color of beet red pigment, and can be used in food at the same time. Vc has a degrading effect on beet red pigment, so it should be used separately when using different food additives.
