1. Botanical classification
Although blueberries have the word "berry" in their names, they have nothing to do with strawberries.
Blueberries, whose scientific name is bilberry, are members of the genus Bilberry in the rhododendron family, distributed in the temperate, subtropical, tropical mountains of the Americas and Asia in the Northern Hemisphere.
The generic name for blueberries is because of the blue "coat" of their fruits.
2. Antioxidants
Time magazine once said, "Blueberries may contain more antioxidants than any other fruit or vegetable." ”
The color of blueberries is derived from the natural pigments they contain, anthocyanins, which are particularly abundant in the peel.
Anthocyanins are natural strong antioxidants and our vision protection gods, which can promote the regeneration of rhodopsin in retinal cells, prevent myopia, and improve vision.
3. Taste
Sourness is her essence.
Blueberries also have high requirements for pH in the soil, and must thrive in acidic soils with a pH below 5.5 and above 3.8.
4. Color
The genus Bilberry is a large family with more than 400 members. So many members are commonly referred to as blueberries because their fruits are generally dressed in blue. Of course, there are exceptions to so many members, such as rabbit-eyed blueberries whose fruits are glowing red, while wild red bean lingonberries are bright red.
5. White frost
Are you curious, the blueberries you buy in the supermarket are sometimes covered with a layer of white frost, what is that? Is it dust?
This "white frost" is not a dirty thing, it is a layer of fruit powder naturally secreted in the process of blueberry ripening, which is not harmful to the human body, and this layer of "white frost" indicates the freshness of the fruit.
