There is a growing trend in the consumption of plant-based raw materials and the use of nuts is a promising alternative in the development of non-dairy foods. This study aimed to produce vegan Dulce de leche with water-soluble baru and cashew nuts extracts (WSBE and WSCE). The WSBE and WSCE were produced using a nut: water ratio of 1:6 (w/v) with the subsequent addition of sucrose and heat treatment to produce Dulce de leche made with baru and cashew nuts (DLBN and DLCN). The nutritional composition of WSBE, WSCE, DLBN, and DLCN showed significant protein and lipids levels with high profile of monounsaturated fatty acids – MUFA and polyunsaturated – PUFA, and lower saturated fatty acids – SFA, leading to lower atherogenicity and thrombogenicity indexes. The Dulce de leche showed a balanced energy value (kcal) and lower hydroxymethylfurfural (HMF) levels. The sensory acceptance test showed a higher scores for WSBE and DLBN for the attributes evaluated, corresponding to “slightly liked” and “moderately liked” when compared to the WSCE and DLCN, with no differences for the purchase intention, which was classified as “probably would buy, probably would not buy”. Thus, the use of water-soluble nut-based extracts can be an alternative for the development of vegan Dulce de leche, contributing positively to consumer health, animal welfare, and the environment. © 2023 Elsevier B.V.

Plasticrusts manifest as a coating on intertidal rocks due to environmental exposure. They refer to crushed plastic debris that blankets rocks found along intertidal shorelines. This study significantly contributes to a better understanding of the occurrence of these novel plastic formations, shedding light on their potential pathways of formation during the Anthropocene era. The research provides comprehensive insights into the composition, origins, challenges, and effective management strategies for removing coastal plastic litter. The findings of this investigation offer valuable evidence regarding the formation and impact of these recently discovered plastic items in coastal regions, prompting discussions about their formation processes and their effects on the marine ecosystem. Recognizing that these newly emerged plastic litter pose a considerable threat to the marine environment is crucial. With their emergence, we face an environmental challenge, especially concerning the health of coastal ecosystems. Plasticrusts, when degraded, can release microplastics (MPs) and nanoparticles (NPs) into the surrounding environment. These micro- and nano-sized plastic particles pose significant ecological risks as they persist in ecosystems, potentially harming wildlife and entering the food chain, causing widespread environmental contamination. Significantly, it outlines strategies to minimize the impact of this emerging plastic debris and its source. © 2024, The Author(s), under exclusive licence to Springer Nature Switzerland AG.

Although the toxicity of selenium (Se) and carbamazepine (CBZ) has already been demonstrated, the possible effects of freshwater fish co-exposure to these pollutants have not been explored. Thus, we aimed to evaluate the potential impact of Se and CBZ (alone and combined) exposure (both 5 µg/L) in Oreochromis mossambicus after 28 days. Exposure to CBZ, alone or combined with Se, significantly increases the "red blood cells" and "mean corpuscular volume." In the gills, malondialdehyde levels in the "CBZ" and "Se + CBZ" groups were lower than in the control group. Furthermore, the exposure to treatments induced a significant increase in protein carbonyl formation in gills and DNA damage in gill and liver cells. Still, acetylcholinesterase activity in the brain was not changed. Thus, our study provides insight into the toxicity of metals and pharmaceutical drugs and warns about the ecotoxicological risk posed by such mixtures. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024.

This study aimed to evaluate the biological activity of clove (Syzygium aromaticum) essential oil and clove extracts, obtained by hydrodistillation, maceration, and ultrasound-assisted extraction. E. coli, L. monocytogenes, S. enteritidis, and S. aureus strains were used to determine the biological activity by the formation of inhibition zones. The chemical profile of the extracts was analyzed in a liquid-phase chromatograph. The ultrasound-assisted essential oils and extracts exhibited biological activity at the concentration of 100 µL/mL, with the highest inhibition halos observed for all strains studied. The essential oil presented greater inhibition for the concentration of 50 µL/mL. The chemical profile analysis demonstrated the presence of groups of gallic acid compounds, flavones, and their isomers. The total phenolics contents ranged from 0.101 and 0.290 mg GAE/g, with the highest values for the ultrasound-assisted extracts. The results of DPPH varied from 8.15 to 65.24%, with an emphasis on ultrasound-assisted essential oil and extracts. © 2023, The Authors. All rights reserved.

Background & Aims: The incidence of cardiovascular disease in climacteric women has increased, becoming the main cause of death in mature women. The use of phytoestrogens, isoflavones, and lignans derived from soy and flaxseed can be natural alternative treatments for this phase of life. This study investigates the utility of isoflavones and lignans derived from soy and flaxseed as natural alternatives to pharmaceuticals to alleviate the symptoms of menopause. Methods: A clinical, prospective, randomized, blind, placebo-controlled trial was performed. For-ty-eight women aged 40 to 65 years were divided into two groups, Phytoestrogen (PHY), which received a cereal bar containing isoflavones and lignans for 90 days, and Placebo (PLA), which received expanded rice flake bar. The sociodemographic, clinical, anthropometric data, blood pressure (BP) measurements, and biochemical and hormonal tests were performed. Results: Forty-three women were included in this study (PHY=21 and PLA=22). There was a significant reduction in diastolic BP in the PHY group after the intervention (p<0.001). The frequen-cy of BP fluctuations in the PHY group significantly decreased to 23.8% after the intervention period (p=0.027), with no significant differences for the other indicators studied. Conclusion: The combination of phytoestrogens showed a trend in reducing the blood pressure of climacteric women. However, no significant changes in cardiovascular risk factors were observed. Clinical Trial Registration: The clinical trial was registered on the REBEC-Brazilian Clinical Trials Registry, number 6z8qqy (https://***/). © 2023 Bentham science Publishers.

Background: Among the various types of cancer, breast cancer is the most incident among women. Due to the resistance to antitumor treatments, alternative treatments have been sought, such as metallic nanoparticles. Objective: This study aimed to evaluate the antitumor potential and cytotoxicity induction mechanisms of green synthesized AgCl-NPs and Ag/AgCl-NPs. Methods: The antitumor potential of nanoparticles was evaluated in breast cancer BT-474 and MDAMB- 436 cell lines treated with 0-40 μg/mL AgCl-NPs or 0-12.5 μg/mL Ag/AgCl-NPs through imagebased high content analysis method. Normal human retinal pigment epithelial 1 (RPE-1) cells were used for comparison. Results: The growth rate of the RPE-1 cells treated with nanoparticles was insignificantly affected, and no significant changes in cell viability were observed. In these cells, the nanoparticle treatments did not induce lysosomal damage, changes in ROS production, or reduction in the mitochondrial membrane potential. The level of BT-474 and MDA-MB-436 cell proliferation was markedly decreased, and cell viability was reduced by 64.19 and 46.19% after treatment with AgCl-NPs and reduced by 98.36 and 82.29% after treatment with Ag/AgCl-NPs. The cells also showed a significant increase in ROS production and loss of mitochondrial membrane potential, which culminated in an increase in the percentage of apoptotic cells. BT-474 cells also presented lysosomal damage when treated with the highest concentrations of both nanoparticle types and actin polymerization was observed after exposure to Ag/AgCl-NPs. Conclusions: Together, the results showed overall cytotoxic effects of both AgCl-NPs and Ag/AgCl- NPs towards breast cancer cells with negligible effects against healthy cells, which suggests their promising anticancer and biomedical applications. © 2024, Bentham science Publishers.

Buriti is a fruit rich in antioxidant compounds, and hydroalcoholic extracts were produced from its pulp to investigate the extraction conditions that result in the highest concentrations of bioactive compounds and maximum antioxidant capacity. The results showed considerable variation in the bioactive compound contents in the pulp: total phenolics (104.64–270.61 mg GAE 100 g-1), total flavonoids (17.74–60.46 mg EC 100 g⁻¹), and total carotenoids (1.30–3.92 mg kg⁻¹). The antioxidant capacity of the extracts, evaluated by DPPH, ABTS, and FRAP methods, ranged from 1.23 to 3.47 μmol ET g⁻¹, 6.34–15.86 μmol ET g⁻¹, and 4.74–11.95 μmol ET g⁻¹, respectively, highlighting the broad diversity of antioxidant activities present in the extracts. Data modeling generated statistically significant mathematical models and contour graphs, which allowed the identification of the optimal extraction conditions for the compounds. Total carotenoids were most effectively extracted with 20 % buriti pulp, intermediate ethanol concentrations, and temperatures around 70 °C. All other bioactive compounds were more efficiently extracted with 5 % buriti pulp, intermediate ethanol concentrations, and temperatures close to 30 °C. The results confirmed the efficiency of the extractions and highlighted the excellent antioxidant potential of buriti pulp. Additionally, the analysis of the optimal regions for extracting antioxidant compounds from the pulp can be applied in future studies to optimize the extraction process, providing a solid foundation for using this fruit in industrial processes, such as the production of functional ingredients. © 2025

Orange-Fleshed Sweet-Potato Flour Development Through Different Drying Techniques Using Multifactorial Analysis for Trending

SSRN

引用

SSRN 2023年

作者： Marinuci, Caroline Alves Batista Narita, Isabela Mendes Pacheco Nascimento, Edgar Silva Faria, Wanessa Costa Nora, Leonardo de Barrosa, Wander Miguel Food and Science Technology Post-Graduation Program Food Physicochemical Laboratory Federal Institute of Education Science and Technology of Mato Grosso campus Cuiabá-Bela Vista MT 78050-560 Brazil Department of Agroindustrial Science and Technology Federal University of Pelotas Pelotas RS Capão do Leão96.010-900 Brazil

This study examines how the processing steps for producing orange-fleshed sweet potato flour affect the desired qualities of the final product, including carotenoid preservation. We tested different drying techniques (oven and freeze-drying) and root fractionation methods (cubes and chips) using a two-level factorial scheme. Significant interaction was found between the two factors (drying and fractionation) in the following assays: carotenoids content (191.21-266.37 µg/g for β-carotene, 191.85-240.47µg/g for α-carotene and 132.35-166.24 µg/g for lycopene), hue angle (45.71 to 65.58), a*(10.84 to 18.55), b* (19.02 to 22.83), water activity (0.07 to 0.26), pH (5.66 to 5.77), total titratable acidity (1.41 to 3.44), water solubility index (26.70 to 42.96), water holding capacity (2.12 to 2.99), protein (2.85 to 3.80) and ashes (3.06 to 3.51). It was noticeable that β-carotene preserved better in freeze-dried cubes. Principal component analysis (PCA) was performed on the data, revealing that oven-dried flours are better for obtaining a crispy texture, while freeze-dried flours may be more suitable for baking. Additionally, there was a strong positive correlation between the a* value and carotenoid content. Overall, the study demonstrates that biofortified sweet potato flour is a viable and affordable raw material for developing novel products from more nutritious crops. © 2023, The Authors.
