Buriti oil nanoemulsions were prepared using non-interesterified buriti or interesterified for 6 24 h (NBO, NBO6h, and NBO24 h), respectively. The aim was to investigate the effects of oils on physicochemical biological properties nanoemulsions. Samples stored at 4 25 °C 30 days, their activities evaluated. mean droplet diameter ranged from 196 270 nm. had smallest size most stable during storage period. Furthermore, demonstrating good oxidative stability, a high antioxidant capacity, less...

Although Amazonian oils present great potential for various applications, they have not been extensively explored commercial use. In this study, the effects of enzymatic interesterification buriti oil in relation to its triacylglycerol composition, regiospecific distribution fatty acids, and minority compounds were evaluated. The results indicated that lipase used reaction showed higher specificity oleic acid sn-1 sn-3 positions triacylglycerol, generating more unsaturated structured lipids....

Extracted from the pulp of an Amazonian fruit, buriti oil is rich in micronutrients with antioxidant properties and high biological value. The few studies available indicate that this could be used a wide range applications; however, there are no work on improvement characteristics for commercial application. enzymatic interesterification one tools to improve oils fats our recent have demonstrated lipase specifically act produce structured lipids oleic acid, while preserving most minor...

The current study aimed to compare the influence of hydroethanolic treatment and enzymatic hydrolysis on antioxidant activity cashew apple bagasse extracts. A three-level Box-Behnken experimental design was applied optimize operational parameters. Hydrolysis parameters, including enzyme concentration (10 %, 15 % 20 respect dry matter), solvent/sample ratio (1:1, 2:1 3:1) sample granulometry were investigated. Hydroalcoholic extraction parameters pH (3.0; 4.5 6.0), ethanol (30 50 70 %). Based...

This study conducted in Sergipe State, Brazil, aimed to investigate the presence of polycyclic aromatic hydrocarbons (PAHs) surface water five rivers and determine their sources, spatial temporal variations, ecotoxicological risks. Correlation principal component analysis were used identify relationship between PAH concentrations sample properties. The results showed higher PAHs during rainy season, indicating increased run-off sediment resuspension. composition suggested a main petroleum...
