Açai Berry (Euterpe oleracea) Dietary Supplements: Variations in Anthocyanin and Flavonoid Concentrations, Phenolic Contents, and Antioxidant Properties

Chemical Composition and Bioactive Properties of Commercial and Non-Commercial Purple and White Açaí Berries

“…Secondly, the pure açaí powder, commercially purchased in the UK, did not show any significant anthocyanin peaks and was below the limit of detection. This implies that the UK sample might have had some other material added to it, that the chemicals might have been lost during processing, or that the samples come from different locations or climates influencing the concentration of the phytochemicals of the berries [ 11 , 42 ]. In comparison with other typical berries, the total anthocyanin content for the non-commercial purple açaí samples ranges from 10.20 to 14.33 mg/g and for the commercial purple açaí samples 3.59 to 4.70 mg/g.…”

Waste management and bioenergy recovery from açaí processing in the Brazilian Amazonian region: a perspective for a circular economy

“…This has been gaining national and international markets as an energetic and functional food, in addition to being a raw material in the pharmaceutical and cosmetics industry. 10 This growing demand is due to the large number of bioactive compounds contained in açaí, which have antioxidant, antiinflammatory, anticarcinogenic, antimicrobial, analgesic, and vasodilatory properties. 9,22 This places açaí as one of the new 'superfruits' .…”

“…Açaí seeds are the primary waste from the açaí processing industry, accounting for 85% of the fruit volume. [9][10][11][12][13][14][15][16] Although they are used as a fertilizer by composting or burnt for thermal energy generation, these applications are not sufficient to absorb the amount of waste generated. Açaí seeds are considered urban waste and are currently a considerable inconvenience affecting health, wellbeing, and hygiene in cities in northern Brazil.…”

“…8,9 The main product extracted from açaí is the pulp, which is consumed throughout the whole country due to its nutraceutical properties, and is exported. 10 Beyond that, açaí presents various applications for the food, pharmaceutical, and cosmetic industries, which are described in the literature. 11 In 2018, Brazilian production of açaí reached 1.7 million tons, 1.5 million from cultivated or managed production, 12 and 221.6 thousand tons from the extractive production, 13 representing a robust economic sector in the northern region of the country.…”

Metabolomics and transcriptomics analyses of sugarcane variety SP80-3280 throughout development in the field

“…This also corresponds to a previous study that showed that oxidative and drought stress conditions increased the flavonoid contents in Arabidopsis leaves, specifically anthocyanins (Nakabayashi et al, 2014), as was the case here seeing that pelargonin, which is involved in anthocyanin biosynthesis, was abundant in the leaves of the "one-year" sugarcane plants (Figure 8 C). Anthocyanins have antioxidant properties (Earling et al, 2019;Kähkönen & Heinonen, 2003;Neill & Gould, 2003), thus the water deficit that the "one-year" sugarcane plants experienced might be the reason why pelargonin levels were high in these leaves.…”
