Cranberry fruit contain about 900 ng of resveratrol per gram dry weight of fruit. angustifolium contain up to 860 ng of resveratrol per gram dry weight of fruit. Studies show that different blueberry varieties of V. Studies suggest that resveratrol can boost apoptosis of cancer cells by enhancing sensitivity to tumor necrosis factor alpha (TNF-α) and reducing NF-κB activation. Resveratrol and its analogs have potent biological properties such as anti-inflammatory, antiaging, antiallergenic, anticarcinogenic, and antimutagenic activities. Resveratrol, pterostilbene, and piceatannol are found in berries including blueberry, cowberry, lingonberry, and acai berry. Stilbenes are phenolic compounds that occur in some berries. Paliyath, in Encyclopedia of Food and Health, 2016 Stilbenes Additional studies are required concerning its safe consumption as a dietary supplements. Its biological effects include it being an antioxidant, an antiinflammatory, a cardioprotective, and a neuroprotective as well as improving dyslipidemia and obesity. Cyanidin 3-glucoside, cyanidin 3-rutinoside, quercetin, orientin, and proanthocyanidins are the major polyphenols found in açai. Studies published in the past on açai pulp or fruit berry extracts have revealed the biological effects associated with its phytochemical composition which is rich in polyphenols: anthocyanins and flavonoids. There is also a growing market for nutraceuticals and dietary supplements containing açai berries, which is claimed to have a large range of health-promoting and therapeutic benefits due to its extraordinary biological properties compared to other fruits. ![]() The consumption of the açai berry, from the açai palm tree ( Euterpe oleracea) in the Amazon, as a functional food is widely used throughout the world. Dirce Fernandes de Melo, in Nonvitamin and Nonmineral Nutritional Supplements, 2019 Abstract Further study is warranted to resolve these questions in order to scientifically promote açaí berries. It is possible that other yet-to-be-identified compounds may also contribute to the antioxidant activity of açaí. Meanwhile, there is not enough information so far to identify the actual or major antioxidants, though anthocyanins, proanthocyanidins, and flavonoids are widely considered. Ingredients such as sugars and salts both have a negative influence on the stability of anthocyanins and antioxidant activity of açaí, hence, the açaí products with less additives are the better choice.Īlthough açaí is popular throughout Brazil and abroad, it should be noted that açaí has been reported to be linked with the outbreak of Chagas’ disease ( Pereira et al., 2009 Nóbrega et al., 2009). It is necessary to adopt proper methods to dry, process, and store açaí and açaí products in order to preserve the antioxidant activity. However, its antioxidants are susceptible to temperature, humidity, light, etc. The açaí berry is regarded as a ‘super fruit’ due to its nutritional properties, especially its antioxidant capacity.
