The anthocyanin contained in blueberry fruit powder is a water-soluble flavonoid pigment. Anthocyanin has unpaired electrons in its molecular structure, which can donate electrons and hydrogen to free radicals to terminate the active oxygen free radicals in the body effectively. The antioxidant capacity is 50 times that of VE and 200 times that of VC. It is one of the natural plant ingredients with the best antioxidant effect found so far.
What Is Blueberry Anthocyanin?
Blueberries are a fruit rich in natural dark blue pigments, commonly known as anthocyanins or anthocyanin pigments. Blueberry fruit is rich in anthocyanin pigments, and the content is also high. It is a group of compounds in which glycosidic bonds bind anthocyanins and sugars. It is a family of compounds that can appear red in a class of substances based on flavonoids. It is derivative of flavonoids and flavanones.
How Much Anthocyanin Is In Blueberry Extract?
The content of anthocyanins in 60 kinds of blueberries collected from Jilin, China was analyzed. It was found that the average content of anthocyanins in fresh blueberries was 5.378 mg/g.
How Strong Does Blueberry Antioxidant Level?
The theory of free radical oxidation is the theoretical basis of human aging and various disease mechanisms. 80%~90% of aging-related diseases are related to free radicals in the human body. Blueberries are rich in anthocyanins with strong antioxidant activity.
1. The crude extract of anthocyanins was extracted from blueberry and its antioxidant activity was determined. It showed that the inhibition rate of anthocyanin free radicals in blueberry was similar to that of VC, and the antioxidant effect on lipids was stronger than that of VC.
2. To test the antioxidant activity of anthocyanin extracts in 5 berries, North American sand fruit, elderberry, red currant, blackberry and blueberry. The oxygen radical absorption capacity (ORAC), hydroxyl radical transfer capacity (HORAC), total hydroperoxide trapping antioxidant parameter (TRAP), NO scavenging and lipid peroxidation inhibition of the extract were determined experimentally. It was found that blueberry extract had the strongest HORAC and NO scavenging ability.
3. The total antioxidant capacity and total superoxide dismutase activity of the liver of the mice were significantly increased after administration of blueberry anthocyanins for 30 days compared with the control group. This shows that blueberries rich in anthocyanins have a good antioxidant effect in vivo.
Summary
Free radicals and antioxidants are an important theoretical basis for diseases such as aging, tumors and cardiovascular diseases. blueberry fruit powder is rich in polyphenols and their good antioxidant activity make them have broad application value and prospects in disease prevention and health maintenance.
