Blueberry extract efficacy and function

1. Antioxidant effect

Blueberry anthocyanin is a natural water-soluble free radical scavenger, its antioxidant activity is 20 times of VC and 50 times of VE. Blueberry anthocyanins have the ability of anti-lipid peroxidation, reduction and scavenging superoxide anion radical and hydroxyl radical. Flavonoids from blueberry pomace have strong antioxidant capacity, especially the antioxidant capacity of purified flavonoids is enhanced. The scavenging capacity of total phenols from blueberry pomace to DPPH is 26.7mgVc/g fresh weight. The scavenging capacity of oxygen free radicals is 24.8 mg Vc/g fresh weight. Blueberry polysaccharide has strong scavenging ability for oxygen free radicals and DPPH.

2. Antimicrobial, anti-inflammatory and analgesic effects

Blueberry extract can inhibit the growth of harmful bacteria and promote the proliferation of beneficial bacteria. Research shows that blueberry extract has inhibitory effect on Escherichia coli, Staphylococcus aureus and Vibrio parahaemolyticus, while adding appropriate concentration of blueberry extract in fermented milk can promote the growth of beneficial bacteria Lactobacillus acidophilus in vitro.

3. Protect eyesight

Prevent blindness, glaucoma, cataract, retinal hemorrhage, improve myopia, macular degeneration, diabetes retinopathy, retinitis pigmentosa and night blindness. The retina is located in a high-oxygen environment, and is vulnerable to oxidative damage under long-term visible light irradiation. Blueberry contains a variety of bioactive ingredients and has the effect of protecting vision. Meng Xianjun and other studies have shown that blueberry anthocyanins can make the retina structure of rats with light injury clear, and the cells are arranged orderly; Effectively prevent the thickness of the chemicalbook layer of the extraretinal nucleus from thinning and the total protein content of the retina from decreasing; The activity of SOD and GSH-Px in retinal cells was significantly increased, and the content of MDA was decreased. Blueberry anthocyanins have obvious protective effects on retinal injury in rats.

In addition, blueberry extract can also prevent cardiovascular diseases, inhibit obesity, improve diabetes and prevent osteoporosis.
