Blueberry fruit powder is a powder made by crushing, squeezing, extracting, spraying or freeze-drying fresh blueberries, which retains the original flavor of blueberries. Blueberries are very rich in pectin, fructose, cellulose, vitamins and other ingredients. Taking some blueberry fruit powder in moderation can effectively absorb the vitamin A in it, improve visual fatigue, and regulate night blindness. Moreover, the content of anthocyanin is relatively rich, which can improve the pigmentation of facial parts and play an anti-oxidant effect. The dha content in blueberry fruit powder is also relatively high, which can enhance memory and regulate Alzheimer's disease. Due to its good water solubility, blueberry fruit powder has been widely used in health products, beverages, and cosmetics.
