Summary: The purpose of this study was to extract and identify the phenolic compounds in two native fruits from southern region of Brazil and evaluate their antioxidant and anti-inflammatory properties. Tannins were the most prevalent phenolic compounds in the fruits, with higher concentrations observed in the methanol extracts. Gallic acid, catechin, vanillic acid, and ellagic acid were identified as the most abundant phenolic compounds. The extracts exhibited significant antioxidant and anti-inflammatory activity, inhibiting the scavenging of DPPH and NO radicals, as well as reducing the release of pro-inflammatory molecules NO and IL-6.

Summary: This study evaluated the antioxidant, anti-inflammatory, and anti-arthritic activities of Coronopus didymus. The extracts showed significant free radical scavenging activity and inhibited protein denaturation, as well as reducing inflammation and edema in arthritic rats. The extracts also had positive effects on blood parameters and oxidative stress biomarkers. These activities may be attributed to the presence of quercetin, ferulic acid, dihydromyricetin, apigenin, vitexin, and kaempferol in the extracts.

Summary: This study aimed to obtain alternative kombucha drinks enriched in phenolic compounds and with a high antioxidant activity using fruits instead of tea leaves. Fruit-based kombuchas prepared with different fruits and microbial consortia were evaluated for their pH, carbohydrate, ethanol, phenolic levels, and in vitro antioxidant capacity during fermentation. The results showed that fruit-based kombuchas, especially the strawberry kombucha, had higher levels of phenolic compounds and exhibited high in vitro antioxidant activity.

Summary: A comprehensive analysis of the phytochemicals in blackberry fruit extract was conducted using HPLC-TOF-MS. The extract contained mainly ursane-type terpenoids and phenolic compounds, which may contribute to its bioactivity. The extract exhibited significant in vitro antioxidant capacity and cellular antioxidant activity, as well as antimicrobial and anti-inflammatory effects. These findings suggest that blackberry fruits are a valuable source of bioactive compounds with potential applications in disease prevention and treatment.

Summary: This study aimed to develop a cellular model using gliadin as a pro-inflammatory stimulus and evaluate the antioxidant and anti-inflammatory properties of extracts from different black rice in the context of celiac disease (CD). The black rice extracts showed inhibitory effects on oxidative and inflammatory mediators, particularly the lymphocyte-attracting CXCL-10. The presence of anthocyanins and their digestion metabolites may account for the observed anti-inflammatory activity after in vitro digestion. These preliminary findings support the potential use of black rice as a healthy food or ingredient for celiacs.

Summary: This systematic review evaluated the impact of propolis administration in diabetic animals. The study found that propolis administration resulted in a hypoglycemic effect in the treated animals, which may be attributed to the reduction of oxidative stress. Additionally, propolis administration restored endogenous antioxidant defenses and improved the lipid profile of the treated animals. However, the review also identified limitations in the studies, including a lack of randomization, blinding, and proper allocation of animals.

Summary: The effect of dynamic gastrointestinal digestion/Caco-2 cell transport on the stability and activities of Brazilian red propolis extract (EEBRP) was investigated. Encapsulated EEBRP showed higher bioaccessibility and nonencapsulated EEBRP had higher Caco-2 cell transport. Nonencapsulated EEBRP exhibited higher ability to scavenge reactive oxygen species and decrease inflammation markers after cell transport. Further studies on encapsulation are encouraged for improving bioactivity and expanding food applications.

Summary: This study evaluated the impact of different lipid sources on gene expression in porcine skeletal muscle tissue using RNA-Seq, and identified differentially expressed genes involved in metabolic pathways and biological processes. Addition of fish oil in pig diets resulted in intramuscular lipid with a higher composition of certain fatty acids. Blood parameters showed lower cholesterol and HDL content in the fish oil group compared to the other two groups. Enrichment analysis revealed differentially expressed genes related to lipid metabolism, metabolic diseases, and inflammation, as well as specific gene functions and altered blood parameters in each group.

Summary: The study investigated the properties of C. arabica leaf extracts, including antioxidant and antiglycation activity, digestive enzymes inhibition, bioaccessibility, and hypoglycemic effect. The extracts showed deactivation of various reactive oxygen species and strong inhibition of alpha-glucosidase and pancreatic lipase. They also exhibited a hypoglycemic effect in zebrafish. All compounds except rutin were detected during in vitro digestion. These findings suggest that C. arabica leaf extracts have potential antidiabetic and anti-obesity properties due to their main metabolites and synergistic action.

Summary: The demand for plant-based products has been increasing, leading to the development of vegetable products analogous to conventional animal-products. This study focused on the ozonation process of peanut milk as an alternative to reduce allergens and mycotoxin contamination. The results showed that ozonation efficiently degraded the most toxic aflatoxins AFB1 and AFG1, while AFB2 and AFG2 were more resistant. Ozonation also showed the potential to reduce peanut allergens by approximately 80%, but it degraded fatty acids and produced off-flavours.

Summary: This study investigates the variations in lipid digestion profiles among individuals of different ages using in vitro digestion models. The findings suggest that adults have a more comprehensive lipid digestion compared to infants, and infants tend to release shorter chain length and more saturated free fatty acids during digestion. Additionally, the particle sizes in the stomach of the elderly were consistently larger. This study enhances our understanding of how lipids with different degrees of unsaturation undergo digestion in diverse age groups.

Summary: This study investigated the acidification of aroma-enhanced black tea during storage. Analysis of non-volatile substances and organic acids using UPLC-Q-TOF/MS and HPLC revealed a decrease in soluble sugars and amino acids, while an increase in organic acids such as oxalic acid, malic acid, and quinic acid. In vitro experiments further demonstrated that the acidification is a result of the decomposition of sugars and amino acids by heating, as well as the oxidation of aromatic aldehydes. Additionally, the study showed that the taste composition of tea infusion is altered, with reduced amino acids, catechins, soluble sugars, and flavonoids. This research provides a theoretical basis for improving the quality of black tea.
