Açaí (Euterpe oleraceae) 'BRS Pará': A tropical fruit source of antioxidant dietary fiber and high antioxidant capacity oil

ABSTRACT

This article reports a study of the concentrations of dietary fiber (DF) and antioxidant capacity in fruits (pulp and oil) of a new açaí (Euterpe oleraceae) cultivar—‘BRS-Pará’, with a view to determine the possibility of using it as a source of antioxidants in functional foods or dietary supplements. Results show that ‘BRS-Pará’ açaí fruits has a high content of DF (71% dry matter) and oil (20.82%) as well as a high antioxidant capacity in both defatted matter and oil. ‘BRS-Pará’ Açaí fruits can be considered as an excellent source of antioxidant dietary fiber. Antioxidant capacity of açaí ‘BRS-Pará’ oil by DPPH assay was higher (EC50=646.3g/g DPPH) than extra virgin olive oil (EC50=2057.27g/g DPPH). These features provide açaí ‘BRS-Pará’ fruits with considerable potential for nutritional and health applications.

    ABSTRACT: The number of dietary fibre enriched food products introduced to the food market has been increased due to several beneficial effects of dietary fibres, mainly on the digestive system. In recent years, there has been a trend towards finding new sources of dietary fibre, such as agronomic by-products. Dietary fibres produced from by-products of antioxidant rich foodstuffs comprise important and healthy antioxidants such as polyphenols and carotenoids. This brings along the antioxidant dietary fibre (ADF) concept, which combines beneficial effects of both dietary fibres and antioxidants. This review focuses on the present knowledge in the literature about the sources and potential applications of ADFs as functional ingredients in the food industry. Also it is aimed to attract the attention of producers to the economic importance of converting those food processing by-products into healthy value-added products.

To avoid this limitation, storage of the DPPH stock solution at low temperature has been reported (Shian, Abdullah, Musa, Maskat, & Ghani, 2012). "

    ABSTRACT: A stable chromogenic radical 2,2-diphenyl-1-picrylhydrazyl (DPPH) is commonly used for the determination of antioxidant activity. In this paper, DPPH was dried into 96 well microplate to produce DPPH dry reagent array plate, based on which the highly sensitive and high throughput determination of antioxidant activities was achieved. The spectrophotometric characterization of the microplate containing dried or fresh DPPH free radicals was reported. The response of the DPPH dry reagent array towards different standard antioxidants was studied. The reaction for DPPH in fresh or dry reagent array with Trolox was reported and compared. The DPPH dry reagent array was used to study the antioxidant activity of banana, green tea, pink guava, and honeydew and the results were compared to the samples reacted with freshly prepared DPPH. The proposed method is comparable to the classical DPPH method, more convenient, simple to operate with minimal solvent required and excellent sensitivity.

    • "Research on radical scavenging activity was based on air-drying temperature (P < 0.05) as seen in Table 3. Antioxidant capacity associated with phenolic compounds was determined by FRAP assay and DPPH methodologies. The different drawbacks and advantages of each one of the available antioxidant capacity assays make it necessary to use different techniques (Rufino et al., 2011). Fresh goldenberry exhibited values of 53. "

    ABSTRACT: Health-conscious consumers prefer a nutritious diet with an increase in fruit intake because of their bioactive compounds. Dehydration is widely used to prolong fruit shelf life. This study researched the effect of convective dehydration on physicochemical properties, color, vitamin C, beta-carotene, total phenolic content (TPC), flavonoids, and antioxidant capacity during dehydration of goldenberry (Physalis peruviana L.) fruits in the 50 to 90 degrees C temperature range. Chromatic parameters (L*, a*, and b*) as well as Chroma and hue angle were affected by drying temperature, which contributed to fruit discoloring during this process. Total phenolic content, flavonoids, and beta-carotene increased from 321.05-356.68 mg gallic acid 100 g(-1) DM, 99.25-144.29 mg quercetin equivalents 100 g(-1) DM, and 722.30-783.16 mg 100 g(-1) sample, respectively, at 90 degrees C. Radical scavenging activity showed higher antioxidant activity at high temperatures than low temperatures. Both vitamin C content and TPC decreased as air-drying temperature decreased. A high correlation was observed between fruit TPC and flavonoids with antioxidant capacity. Based on these results, this fruit has potential for the development of new functional products.
