Blueberries belong to the genus Vaccinium of the Ericaceae family and are also known as cranberries or cranberry fruits. They are perennial evergreen shrubs with berries as their fruits. The earliest country to cultivate blueberries was the United States, but the cultivation history there is less than a hundred years. In China, blueberries are mainly produced in the Greater and Lesser Khingan Mountain forest regions, especially in the central part of the Greater Khingan Mountains. They are all wild and have not been artificially cultivated until recently. Blueberries have high health value and are called "Queen of Fruits" and "the fruit for beautiful eyes". They are one of the five healthy fruits recommended by the Food and Agriculture Organization of the United Nations.

The vitamins and trace elements contained in blueberries are higher than those in other fruits. Take vitamin E as an example. The content of vitamin E in 100 grams of fresh blueberries is 2.7-9.5 ug, which is several times or even dozens of times that of other fruits such as apples and grapes. The specific nutritional components and contents are shown in the following table.

Blueberry powder is a kind of powder made of blueberry as raw material, its flavor is sweet and sour, and it is very rich in vitamin C, vitamin E, vitamin A and other ingredients.

In addition, the protein, anthocyanin and dietary fiber in blueberry powder is also relatively rich, can effectively promote metabolism, accelerate intestinal peristalsis, can prevent cardiovascular and cerebrovascular diseases.

As a small berry species with high economic value and broad development prospects, blueberries rank first among the 15 healthy foods listed by authoritative nutritionists in the United Kingdom, and were listed as one of the five health foods for human beings by the International Food and Agriculture Organization of the United Nations in 2017, and are known as the “king of berries”.
