The aim of this paper was to evaluate the effect high energy ultrasound on bioaccessibility bioactive compounds from açaí (Euterpe precatoria) and buriti (Mauritia flexuosa) juices. Five levels density (0, 0.9, 1.8, 2.7 3.6 J.cm−3), as well their effects were evaluated. Ultrasound did not significantly influence pH, titratable acidity soluble solids. However, it affected color attributes juices by increasing brightness variation. concentration (anthocyanins carotenoids) antioxidants...
This study evaluated the effects of High-Temperature Short Time (HTST), Ultra High Temperature (UHT), and non-thermal processes Power Ultrasound (US), UV-pulsed-light Low Pressure Plasma (LPP) on composition, stability, bioactive compounds bioaccessibility açai juice. 1H NMR based approach, coupled to chemometrics, was applied evaluate changes in juice composition. All increased sugars content (glucose fructose), amino acid betaine, except combined processing ultrasound followed by...
The multivariate chemical analysis of essential oils Eugenia uniflora leaves with different fruit colours indicated the presence three oil clusters regarding sample biotypes. first cluster included yellowish, dark red and purple fruits high percentages germacrene B (11.1-30.7%), germacrone (9.8-54%) atractylone (0-19.9%). In II, bright samples, major constituents were curzerene (42.0-43.2%), D (8.7-9.0%) A (5.9-8.9%), whereas III red-orange samples containing contents...
NMR and chemometrics was applied to understand the variations in chemical composition of coconut water under different processing. Six processing treatments were analyzed: two control (with without sulphite), four samples thermally processed at 110 °C 136 sulphite). Samples lower temperature sulphite presented pink color storage. According chemometrics, higher exhibited levels glucose malic acid. with amount sucrose, suggesting degradation carbohydrates after harshest thermal treatment....
Sweet potato peels are rich in chlorogenic acids. In this work, we applied ultrasound technology to extract the main compounds from sweet peel and used multivariate analysis principal component (PCA) evaluate effects of different extraction conditions on The was studied varying ultrasonic power density (20, 35 50 W/L) processing time (5, 10, 20 40 min) using an bath operating at 25 kHz. chemical carried out by UPLC-qTOF-MS, results were evaluated PCA PLS-DA chemometric analysis. Results show...
