Blueberry extract anthocyanins are natural plant compounds that have strong antioxidant properties. It is widely used in the fields of food, health care products and drugs, and has been widely concerned and loved by people.
Blueberry extract anthocyanins are mainly derived from the common fruit blueberry. Blueberries are small berries grown in regions such as North America, Europe and Asia, whose fruits appear dark blue or purple and are rich in many vitamins and minerals, and are known as the "king of fruits." There are abundant anthocyanins in blueberry, which are dominated by anthocyanin compounds, including anthocyanin, anthocyanin side, anthocyanin alcohol and so on. These anthocyanin compounds have a strong antioxidant effect, can effectively remove free radicals in the body, delay aging, and prevent the occurrence of various chronic diseases.
Second, the chemical structure of anthocyanins in blueberry extract
The chemical structure of anthocyanins in blueberry extract is mainly composed of anthocyanins, anthocyanins glycosides and anthocyanins alcohols. Anthocyanins are a natural plant pigment that has a strong antioxidant effect and can protect cells from oxidative damage. Anthocyanin is a compound formed by the combination of anthocyanin and sugar molecules, which has better stability and solubility and is easier to be absorbed and utilized by the human body. Anthocyanin alcohol is the reduction product of anthocyanin, which has stronger antioxidant activity, can effectively remove free radicals in the body and protect cells from oxidative damage.
Bioactivity of anthocyanins from blueberry extract
Anthocyanins of blueberry extract have various biological activities, including antioxidant, anti-inflammatory, anticancer, hypoglycemic, hypolipidemic and so on. First of all, blueberry extract anthocyanins have a strong antioxidant effect, can clear free radicals in the body, delay aging, and prevent the occurrence of various chronic diseases. Secondly, blueberry extract anthocyanins also have a good anti-inflammatory effect, can reduce inflammatory response, relieve pain and swelling. In addition, anthocyanins from blueberry extract also have anti-cancer, hypoglycemic, hypolipidemic and other effects, which can effectively prevent and treat a variety of diseases.
Nutritional value of blueberry anthocyanins
1. Blueberry anthocyanins are small molecules and water-soluble substances, which can be absorbed by the human body by oral administration and can quickly enter various tissues and organs of the human body. Blueberry anthocyanins are stable under acidic conditions and have a strong affinity for connective tissue, with a half-life of up to 27 hours.
2. Blueberry anthocyanins also help the body absorb vitamin C and vitamin E. Blueberry anthocyanins and collagen have a strong affinity, can promote the formation of moderate crosslinking of collagen, and can prevent the body from being oxidized by free radicals. The total content of anthocyanin in blueberry is 132mg/100g, and there are 13 kinds of anthocyanin compounds, such as mallow pigment, anthocyanin, centaurea, morning glory pigment, paeoniflorin and so on.
3. Blueberry anthocyanins can prevent the abnormal physiological condition of skin "overcrosslinking", which further prevents skin wrinkles and the appearance of skin vesicles. Anthocyanins can also effectively prevent the production of hard protease, and can inhibit the degradation of elastase to hard protease, gradually improve the human skin from the inside out, making human skin healthier. The price of blueberry extract with 25% anthocyanin content in the market is 5-6 times that of grape seed extract with 95% content, which shows that the nutritional value of blueberry anthocyanin is unmatched by other varieties.
Health benefits of anthocyanins: Anthocyanins are natural anti-aging nutritional supplements that have been shown to be the most effective antioxidant found today, with antioxidant properties 50 times higher than vitamin E and 200 times higher than vitamin C. It is 100% bioeffective in humans and can be detected in the blood within twenty minutes of taking it.
Anthocyanins in Europe, known as "oral skin cosmetics" especially blueberry anthocyanins, nutrition skin, enhance skin immunity, to deal with various allergic symptoms. It is nature's most potent antioxidant. It can not only prevent the early generation of skin wrinkles, but also maintain normal cell connections, the stability of blood vessels, enhance microvascular circulation, improve the flow of microvessels and veins, and thus achieve rapid healing of abnormal skin.
Anthocyanins are natural sun coverings that protect the skin from UV rays. Skin is a connective tissue, which contains collagen and hard proteins that play an important role in the overall structure of the skin.
Anthocyanins play a dual role in skin action:
1, it can promote the formation of collagen crosslinking;
2, as an effective free radical scavinger, it can prevent the occurrence of the abnormal physiological condition of "over-crosslinking" of the skin, thus preventing the appearance of skin wrinkles and vesicles, anthocyanin can also prevent the production of hard protease and inhibit its activity to prevent free radicals or elastase degradation of hard protein, significantly improving the health of the skin from the inside.
Application fields of anthocyanins from blueberry extract
Anthocyanins from blueberry extract are widely used in food, health care products and medicine. In the field of food, blueberry extract anthocyanins can be used as natural pigments and preservatives to add color and flavor to food and extend shelf life. In the field of health products, blueberry extract anthocyanins can be used as antioxidants and nutritional supplements to help the body clear free radicals and boost immunity. In the field of medicine, blueberry extract anthocyanins can be used to prevent and treat a variety of diseases, such as cardiovascular disease, diabetes, cancer and so on.
The main extraction process of blueberry anthocyanins: A certain number of fresh blueberries were weighed, made into blueberry pulp, soaked with the extract solution according to the optimal extraction conditions, and then extracted. The purplish red blueberry anthocyanin extract was obtained through filtration. The pigment extract was purified by AB-8 macroporous adsorption resin, 60% ethanol solution was used as eluent, and samples were collected at a temperature of 60 degrees Celsius. The purplish red blueberry anthocyanins were obtained by reducing pressure, concentrating and recovering ethanol under vacuum of 88kPa and then drying under vacuum.
In summary, anthocyanins from blueberry extract are a kind of natural plant compounds with strong antioxidant effect, which have a variety of biological activities and a wide range of applications. As people pay more attention to health and the demand for natural products increases, blueberry extract anthocyanins will be more widely used and developed in the future.
