Black wolfberry is known as the "king of anthocyanins". Its content exceeds that of blueberries. It is currently the wild plant with the most anthocyanins and is of great benefit to the human body.

Blueberries and anthocyanins are known as "oral skin cosmetics" in Europe, especially blueberry anthocyanins, which nourish the skin, enhance skin immunity, and cope with various allergic symptoms.

Mulberries have a particularly high sugar content and are seasonal and cannot be eaten all year round. Therefore, they are also extremely suitable for making wine.

Black wolfberry and red raspberry are the most important anthocyanins. Freeze-dried anthocyanins are freeze-dried from nine kinds of berries, including blueberries, blackberries, black wolfberries, black currants, red wolfberries, cranberries, mulberries, blue indigo, and red raspberries, using low-temperature freeze-drying technology and wall-breaking crushing. of anthocyanin powder.

Anthocyanins adopt a low-temperature freeze-drying process, which means it is carried out below 0℃, that is, it is carried out in the frozen state of nine kinds of berries. Under vacuum conditions, when the water vapor directly sublimates out, the berries and active substances remain in the frozen ice shelf, forming a sponge-like loose porous structure, so its volume remains almost unchanged after drying. When brewing, the water temperature should be lower than 40°C to maintain the biological activity of the freeze-dried anthocyanins.
