Brazilian berries are often regarded as superfoods. They are dark purple berries produced from the Acai palm tree in South America. They are the most well-known antioxidant active substances in the world. Brazilian berries are easily absorbed by the human body and are immune system boosters. They are low in sugar and are a good source of fiber. Brazilian berries are also an excellent source of multiple nutrients, such as unsaturated fatty acids, vitamin E, and phytosterols, and can provide a perfect complex of almost all essential amino acids.
Acai berry is a large tropical tree with a long and slender trunk, 15 to 30 meters in height and a trunk diameter of 10 to 15 centimeters. The leaves are pinnate and up to 3 meters long.

Unripe acai berry is green, and when ripe, the fruit is black-purple, with a thin edible flesh containing a large core.
Main value
1. Anthocyanins
A large number of research results show that the fruits of acai berry mainly contain anthocyanins (ACNs), proanthocyanidins (PACs) and other flavonoids. After analysis, anthocyanidin-3-glucoside and anthocyanidin-3-rutinoside are the main anthocyanidin components. The total content of anthocyanins is 3.1919 mg/g (DW). The total content of anthocyanidin glycosides is 12.89 mg/g (DW).
2. Polyphenols
The fruits of acai berry also contain a variety of polyphenol compounds. Contains 94mg/kg of vanillic acid, 62mg/kg of syringic acid, 52mg/kg of p-hydroxybenzoic acid, 36mg/kg of catechin, 5.9mg/kg of ferulic acid, and 4.8mg/kg of (+)-erucic acid.
3. Other ingredients
The fruit of acai berry also contains fatty acids, sterols, amino acids, polysaccharides, minerals, etc. Polyunsaturated fatty acids, monounsaturated fatty acids and saturated fatty acids account for 111.1%, 60.2% and 28.7% of the total fatty acids, respectively. Among them, oleic acid accounts for 60% of the total fatty acids, palmitic acid accounts for 22%, oleic acid accounts for 12%, stearic acid and other fatty acids account for 0.6% of the total fatty acids.
