ABSTRACT: The objective of this research was to evaluate the nutritional composition and bioactive compounds whole umbu fruit, including pulp, seed peel, also a commercial pulp. Samples fractions pulp were analyzed for determination minerals proximate composition, total phenolic antioxidant activity. Pulps peel vitamin C carotenoids contents. Commercial presented better than fresh (P<0.05) higher content activity seed. Peel stood out by its (79 mg.100 g-1) (2,751 µg.100 contents, showing...
O objetivo deste trabalho foi utilizar o etanol comercial para extração e fracionamento simultâneos das frações lipídicas presentes na castanha-do-Brasil (Bertholletia excelsea H.B.K.). óleo obtido a partir da castanha desidratada moída. processo conduzido proporção 4:1 solvente/substrato (v.p-1) em banho termostatizado 65 °C, sob agitação de 30 rpm. A mistura filtrada, resfriada 10 °C e, seguir, centrifugada separação fases: uma fase com consistência gel (micela rica), contendo 75% 25%...
Pomegranate (Punica granatum L.) is a fruit with long medicinal history, especially due to its phenolic compounds content, such as the anthocyanins, which are reported one of most important natural antioxidants. The analysis anthocyanins by high performance liquid chromatography (HPLC) can be considered an tool evaluate quality pomegranate juice. For research laboratories major challenge in using HPLC for quantitative analyses acquisition purity analytical standards, since these expensive...
The present work aimed to obtain bioproducts from Passiflora cincinnata seeds, the Brazilian Caatinga passion fruit, as well determine their physical, chemical and biological properties. seeds were pressed in a continuous press oil, which showed an oxidative stability of 5.37 h fatty profile rich linoleic acid. defatted evaluated for recovery antioxidant compounds by central rotation experimental design, varying temperature (32-74 °C), ethanol (13-97%) solid-liquid ratio (1:10-1:60 m/v)....
Cold pressing is an environment-friendly mechanical extraction for oils from seeds. In this work, cold-pressed green Arabica coffee oil was investigated related to the influence of variables (preheating, exit diameter, screw speed, and particle size) on chemical composition, mainly diterpenes and, first time in scientific literature, content serotonin amides (β N-alkanoyl-5-hydroxytryptamides (Cn-5HT)). The yield varied 2.65 6.27%, with major yields obtained as size temperature increased....
The genus Spondias has two species of native trees from Brazil that deserve to be highlighted: tuberosa (“umbu”) and mombin (“cajá”). Their fruit contain bioactive compounds which have been associated with several biological activities. However, they remain little exploited in the development food pharmaceutical products. In this perspective, present review summarizes literature data about physicochemical nutritional characteristics, compounds, potential health benefits, industrial...
Abstract According to the Food and Agricultural Policy Research Institute, demand for edible oils fats is growing. Tucumã a native Amazonian fruit with high lipids content in pulp kernel. The oil has of unsaturated fatty acids carotenoids, mainly β‐carotene, pro‐vitamin A. Kernel fat oxidative stability as it rich saturated acids, predominance lauric acid. kernel can formulate functional due their physicochemical, nutritional, sensory properties. This paper aims provide an overview...
O camu-camu é um fruto da região amazônica que despertou interesse comunidade científica devido à sua elevada concentração de vitamina C. processamento do camu-camu, para obtenção suco, uma alternativa aumentar a conservação e incentivar o seu consumo. Processos separação por membranas são conduzidos em condições brandas temperatura pressão, preservando compostos termossensíveis e, consequentemente, qualidade produto final. Este trabalho teve como objetivo avaliar desempenho processo...
The aim of this work was to evaluate the effect mechanical pressing on jussara oil yield, oxidative stability and carotenoid profile with or without heat application. Firstly, pulp centrifuged for juice extraction, resulting cake dried until reaching 10% moisture content. Then, extraction performed in an expeller press at 25 ºC (cold pressing) 50 (hot pressing). process performance evaluated by crude characterized fatty acid composition, value, stability. Jussara contained 74% unsaturated...

The main objective of this study was to develop an affordable bioactive food ingredient from a blend pressed pomegranate seed oil (PSO) and soybean (SO) microencapsulated by spray drying.Compared liquid blends, the powder presented higher oxidative stability (42%) due effective protection carrier agents antioxidant capacity (two-fold) characteristic applied material, proving be adequate alternative associate oils.
Microencapsulation by spray drying is widely utilized for preserving and stabilizing essential fatty acids functional oils. Recent studies have demonstrated that both flow rate thermodynamic properties of air, along with the composition emulsion, directly impact quality microparticles. In this work, a single droplet device was used to quantitatively establish behavior emulsions containing oil typical encapsulating agents—gum arabic, modified starch, maltodextrin. The kinetics emulsion...
