About Brazilian Acai

 

A powdered preparation of freeze-dried açaí fruit pulp and skin was reported to contain (per 100 g of dry powder) 533.9  calories , 52.2 g  carbohydrates , 8.1 g  protein , and 32.5 g total fat. The carbohydrate portion included 44.2 g of  Dietary Fiber  and low sugar value (pulp is not sweet). The powder was also shown to contain (per 100 g): negligible  vitamin C , 260 mg  calcium , 4.4 mg iron, and 1002 U  vitamin A , as well as  aspartic acid  and  glutamic acid ; the  amino acid  content was 7.59% of total dry weight (versus 8.1% protein).

The fat content of açaí consists of  oleic acid  (56.2% of total fats),  palmitic acid  (24.1%), and  linoleic acid (12.5%). Açaí also contains  beta-sitosterol  (78–91% of total sterols). The oil compartments in açaí fruit contain polyphenols such as  procyanidin  oligomers and  vanillic acid , syringic acid,  p-hydroxybenzoic acid , protocatechuic acid , and  ferulic acid , which were shown to degrade substantially during storage or exposure to heat.

A comparative analysis from  in vitro  studies reported that açaí has intermediate  polyphenol  content and  antioxidant  potency among 11 varieties of frozen juice pulps, scoring lower than  acerola ,  mango ,  strawberry , and  grapes .

 

A powdered preparation of  freeze-dried  açaí fruit pulp and skin was shown to contain  cyanidin 3-O-glucoside  and  cyanidin 3-O-rutinoside  as major anthocyanins ; (3.19 mg/g) however, anthocyanins accounted for only about 10% of the overall antioxidant capacity in vitro.The powdered preparation was also reported to contain twelve flavonoid-like compounds, including  homoorientin ,  orientin ,  taxifolin deoxyhexose ,  isovitexin ,  scoparin , as well as proanthocyanidins  (12.89 mg/g), and low levels of  resveratrol  (1.1 μg/g). A study on another different freeze-dried açaí product (Opti-Acai) reported that the formulation contained much lower levels of anthocyanins,  proanthocyanadins , and other polyphenol compounds as compared with  blueberries  and other antioxidant-rich fruits.

In an in vitro study of different açaí varieties for their antioxidant capacity, a white one displayed no antioxidant activity against different  oxygen radicals , whereas the purple variety most often used commercially had antioxidant activity against  peroxyl radicals  and to a lesser extent  peroxynitrite but little activity against  hydroxyl radicals .

Freeze-dried açaí powder was found to have  antioxidant  activity in vitro against  superoxide  and peroxyl radicals, and mild activity for peroxynitrite and hydroxyl radicals.The powder was reported to inhibit  hydrogen peroxide -induced oxidation in  neutrophils , and to have a slight stimulatory effect on the reactive radical,  nitric oxide .
