The Functional Carbonated Beverage Properties of Guabiroba Juice Using the Ice Fraction from Gravitational Block Freeze Concentration [PDF]

open access: yesProcesses
The freeze concentration of liquid foods generates a by-product that has few academic studies and no industrial application: the ice fraction of each concentration stage. Sugar-free carbonated beverages were produced from the addition of 20% residual ice fraction (stage 1—I120 and stage 2—I220) of the gravitational block freeze concentration process ...

The Addition of Concentrated Cold-Pressed Guabiroba Juice to Yogurts: Effects on the Physicochemical Analyses, Antioxidant Activity, Carotenoid Content, Total Phenolic Compounds, and Mineral Profile [PDF]

open access: yesProcesses
Cold-pressed guabiroba juice was subjected to block freeze concentration. The best process efficiency (PE) was obtained for the first stage of freeze concentration compared to the second stage (C2; 57.47%). Yogurt formulations were carried out with the concentrated juice from stage 1 (C1) (0, 10% (I10), and 15% (I15)).

Optimization and sensorial evaluation of guabiroba jam with prebiotic [PDF]

open access: yesPesquisa Agropecuaria Brasileira, 2020
Abstract: The objective of this work was to optimize formulations of guabiroba (Campomanesia xanthocarpa) jam by central composite design (CCD), to evaluate the addition of pectin (P), citric acid (CA), and fructo-oligosaccharides (FOS). The responses were pH, titratable acidity, and hardness.

Influence of guabiroba pulp (campomanesia xanthocarpa o. berg) added to fermented milk on probiotic survival under in vitro simulated gastrointestinal conditions

Food Research International, 2021
In fermented milks inoculated with two thermophilic strains (Lactobacillus bulgaricus and Streptococcus thermophilus), guabiroba pulp (Campomanesia xanthocarpa O. Berg) was added in different concentrations: 5% (I5 sample) and 10% (I10 sample), compared to a control sample, with no pulp addition.

Sensitivity of different parameters for selection of higher plants in urban afforestation: Exposure of Guabiroba (Campomanesia xanthocarpa O. Berg.) to diesel engine exhaust

Environmental Pollution, 2020
Urban afforestation can mitigate the effects of air pollution by acting as a sink for atmospheric emissions, but these emissions (e.g., combustion gases from diesel engines) can be a precursor of structural and physiological changes in higher plant species, which could compromise the success of afforestation projects.

Polyphenolic compounds with biological activity in guabiroba fruits (Campomanesia xanthocarpa Berg.) by comprehensive two‐dimensional liquid chromatography

ELECTROPHORESIS, 2020
AbstractThis study aimed to evaluate the polyphenolic composition along with the biological activity of guabiroba (Campomanesia xanthocarpa Berg.) fruits using comprehensive two‐dimensional liquid chromatography (LC × LC). A simplex centroid design comprising three solvents (methanol, 2% acetic acid, and acetonitrile) was used to optimize the ...

PROCESSOS HIDROLÓGICOS SUBSUPERFICIAIS INFLUENCIADOS POR CORTES DE ESTRADAS RURAIS NA BACIA HIDROGRÁFICA DO RIO GUABIROBA, GUARAPUAVA, PARANÁ, BRASIL

open access: yesCaminhos De Geografia, 2021
Although rural roads allow the development of rural communities, they alter the natural hydrological response of the river basin. This study was carried out in the Guabiroba River Basin, Guarapuava-PR, Brazil, in order to verify how subsurface hydrological processes are influenced by rural road cuts. For that, field surveys were carried out to identify

Nanoencapsulation of hydrophobic phytochemicals using poly (dl-lactide-co-glycolide) (PLGA) for antioxidant and antimicrobial delivery applications: Guabiroba fruit (Campomanesia xanthocarpa O. Berg) study

open access: yesLWT - Food Science and Technology, 2015
AbstractPrevious studies have reported antioxidant and antimicrobial activity of guabiroba extract (GE), which is associated to its polyphenolic and carotenoid contents. Encapsulation using polymeric materials could improve GE application, bioavailability, and stability in foods and pharmaceuticals.
