Blueberry Extract – Anthocyanins
Blueberry anthocyanins are derivatives of flavones and flavanones, sourced from blueberry fruits belonging to the genus Vaccinium within the Ericaceae family. They are produced through processes including enzymatic hydrolysis, water extraction, and purification, resulting in a deep-purple amorphous powder (which may also appear in block or liquid form). The total anthocyanin content is ≥40.0 g/100 g.

II. Product Introduction
1. Source
Blueberry extract—anthocyanins 25%—is refined from the fruits of blueberry plants (genus Vaccinium, family Ericaceae). Its production process includes steps such as selecting high-quality raw materials, washing the raw materials, performing three rounds of extraction, concentrating the extract, spray-drying it into powder, and then sieving and sterilizing the powder. Through a scientifically optimized extraction and purification process, this product maximizes the preservation of the active ingredients’ structure and efficacy. Native to North America, blueberries are primarily found in northeastern, eastern, and southwestern regions of China, where the raw materials boast excellent quality.
2. Core Efficacy and Applications
(1) Pharmaceutical field
Anthocyanins in blueberry extract exhibit outstanding antioxidant properties, effectively scavenging free radicals in the body and protecting cells from oxidative damage. At the same time, they can promote the regeneration of rhodopsin in retinal cells, improve ocular blood circulation, and effectively relieve eye fatigue while enhancing visual acuity. Based on these properties, blueberry extract can be used as an ingredient in health foods designed to alleviate eye fatigue and protect vision, such as tablets, capsules, and chewable tablets.
(2) Food sector
As a water-soluble natural pigment, anthocyanins from blueberry extract can be used in the food processing industry to provide natural purplish-red coloring for juices, jams, baked goods, dairy products, and other foods, thereby meeting consumers’ demand for natural and healthy food products.
(3) Cosmetics field
Thanks to its powerful antioxidant properties, blueberry extract—containing 25% anthocyanins—can be added to skincare products to help protect the skin from free-radical damage, reduce UV-induced skin damage, brighten the complexion, and slow down skin aging. It is suitable for a variety of cosmetic formulations, including lotions, serums, face masks, and eye creams.(4) Food sector
