Açaí (Euterpe oleracea Mart.) is a berry found in Amazon Rainforest. Due to its increasing commercial value, the cultivation of this fruit in northern Brazil is growing quickly, and with it the increasing production of waste by this industry also poses a growing problem. This study presents a characterization of all residual fractions of the industrial processing of açaí and assesses its potential as biomass and phytochemicals source, determining the content of lipids, extractives, sugars, ashes, proteins, and the phytochemical composition of each residual fraction. It also studies the extraction of these compounds by intensified microwave-assisted techniques (ambient-pressure microwave extraction and pressurized microwave extraction at 1.5 bar and 3 bar). The oil content represents 43.1 % of the dry pulp weight, in which fatty acids such as oleic acid (58.5 %), linoleic acid (22.3 %), palmitic acid (11.4 %) and stearic acid (4.1 %) were identified. The pulp and seeds showed potential as antioxidant agent with ORAC (oxygen radical absorbance capacity) values of 89,760 and 65,263 μmol TE/100 g_DM. Microwave pre-treatments allowed to increase the polyphenol contents and the antioxidant activities of extracts obtained from the pulp and seed residues, yielding products of interest for the cosmetic or food industry.

阿塞拜疆（Euterpe oleracea Mart。）是在亚马逊热带雨林中发现的浆果。由于其商业价值的提高，巴西北部这种水果的种植正在迅速增长，随之而来的是该行业废物产量的增加也带来了日益严重的问题。这项研究提出了巴西莓工业加工过程中所有残留部分的特征，并评估了其作为生物质和植物化学物质来源的潜力，确定了脂质，提取物，糖，灰分，蛋白质的含量以及每个残留部分的植物化学组成。它还研究了通过增强微波辅助技术（环境压力微波提取和1.5 bar和3 bar的加压微波提取）提取这些化合物的方法。含油量占纸浆干重的43.1％，其中脂肪酸（例如油酸）占58.5％，鉴定出亚油酸（22.3％），棕榈酸（11.4％）和硬脂酸（4.1％）。果肉和种子显示出作为抗氧化剂的潜力，ORAC（氧自由基吸收能力）值分别为89,760和65,263μmolTE / 100 g_DM。微波预处理可以增加纸浆和种子残留物中提取物的多酚含量和抗氧化活性，从而为化妆品或食品工业带来重要的产品。
