In this paper, the effects of processing and storage on physicochemical properties and retention of antioxidant compounds of no-added sucrose chewy candies (NASC) incorporated with differently processed acai (frozen pulp, spray-dried and freeze-dry powders) were investigated.Abstract:
Summary
This study investigated the effects of processing and storage on the physicochemical properties and retention of antioxidant compounds of no-added sucrose chewy candies (NASC) incorporated with differently processed acai (frozen pulp, spray-dried and freeze-dried powders) NASC containing freeze-dried acai had the highest softness and recoveries of total phenolic (TP) and total anthocyanin (TA) immediately after production Colour parameters and antioxidant capacity by ABTS and ORAC assays had no significant differences after 6 months of NASC storage, except for ORAC in NASC containing spray-dried acai, whereas DPPH• in all samples significantly increased Water activity and hardness also increased after storage, whereas TP and TA contents decreased, despite presenting good retentions (approx 72–78% TP and 84–99% TA) This study suggests that acai has a great potential to be used as a natural pigment and antioxidant source in candy manufacturing, meeting consumption trends towards healthier productsread more

Antioxidant properties of acai (Euterpe oleracea) in the metabolic syndrome.
Paula Cavalcante Amélio Silva Cedrim,Elenita Marinho Albuquerque Barros,Ticiano Gomes do Nascimento +2 more
Abstract: Resumo Alimentos ricos em polifenois, considerados com alto poder antioxidante, principalmente da classe antocianinas, estao sendo cada vez mais utilizados na prevencao de doencas relacionadas a sindrome metabolica. Um fruto que se destaca por apresentar essa propriedade e o acai ( Euterpe oleracea). O Brasil e o maior produtor da fruta e o mercado estrangeiro vem investindo na sua importacao para utilizacao tanto na industria alimenticia quanto farmaceutica. O objetivo do estudo foi realizar uma extensa revisao da literatura sobre as propriedades funcionais do acai relacionadas a sindrome metabolica. A busca de dados foi realizada em bases, como Pubmed, Web of Science, Scielo e Science Direct. Assim, observou-se que Euterpe oleracea e um fruto rico em antocianinas, as quais atuam modulando o metabolismo lipidico para minimizar os danos no organismo causados pelo estresse oxidativo, desencadeado por doencas cronicas.
