The jaboticaba is a fruit with a highly promising chemical profile for producing fermented products with biological activity. In this context, evaluating pre-fermentative maceration techniques in jaboticaba fermentations is essential to optimize the extraction of phenolic compounds and other metabolites of interest, imparting antioxidant characteristics to the product and offering potential health benefits. This study evaluated the impact of two pre-fermentative maceration techniques on the phenolic composition, bioaccessibility, and biological activities (α-amylase, α-glucosidase, and ACE inhibition) of alcoholic and acetic fermented products from jaboticaba.

Unlabelled: The study investigated the efficacy of infusions on human melanoma cells (SK-MEL-28). The phytochemical profile revealed 18 phenolic compounds in the leaf infusion and 9 in the fruit infusion. After 24 h of treatment, the infusions demonstrated antineoplastic effects, reducing cell viability at all tested concentrations for the leaf infusion.

Among the 33 phenolic compounds investigated, 25 were quantified, and only eight were not bioaccessible (p-aminobenzoic acid, sinapic acid, pinobanksin, isorhamnetin, quercetin-3-glucoside, syringaldehyde, coumarin, and coniferaldehyde). Benzoic acid was predominant in most undigested samples (21.

J774 macrophages were stimulated with lipopolysaccharides (1 µg/mL) and treated with various concentrations (1-100 µg/mL) of juçara fruits extracts from crude extracts, and hexane, dichloromethane, ethyl acetate, and butanol fractions. Potential relationships between the phenolic composition of the extracts determined by LC-ESI-MS/MS and their anti-inflammatory capacity were also evaluated.

Background: This study evaluated for the first time the potential of orange passion fruit as a base for alcoholic and acetic fermentations, with a view to assessing its profile of organic acids and polyphenols, in vitro digestion, and biological activities.
Results: In terms of aliphatic organic acids, malic acid was the majority in the wine (3.19 g L), while in the vinegar, it was acetic acid (46.
Santa Catarina is the main producer state of oysters and mussels in Brazil, reaching 98 % of national production. To assure the safety of bivalve mollusks production, control programs of marine biotoxins (MBs) have been continuously performed. Herein, the co-occurrence of MBs and contaminants of emerging concern (CECs) in oyster and mussels from the main production sites of Santa Catarina was reported, covering 178 compounds.

The objective of this work was to determine the phenolic composition, chemical and cellular antioxidant activity, cytotoxicity in human cells, and peroxidative inhibition of the defatted fraction of grape () and blackberry () seeds. Soxhlet extraction (Sox) was used to extract the fat and obtain the degreased material. A statistical optimization study was developed to maximize the extraction of bioactive compounds and antioxidant activity from defatted grape and blackberry seeds.

Sanitary and analytical control programs are developed to detect the occurrence of these toxins in seafood before they reach toxic levels. To ensure quick results, methods must be easy and fast to perform.

Non-conventional edible plants are widely present in Brazil. Several fruits of spontaneous occurrence are underestimated and scarcely used by the population. The increase in the knowledge about these plants, especially regarding the bioactive compounds present in this species, is important to increase its use, cultivation, and propagation.

The fruits of palm trees (Arecaceae) are a very important food source for fauna and for humans, despite the still incipient role of these fruits in conventional diet. Seven palm tree species (plus one variety) that are native to the southern half of South America located east of the Andes (Argentina, Paraguay, Uruguay, and the southern states of Brazil) were studied. For the first time, the fatty acid profiles of palm seeds and the content of both amino acids and phenolic compounds present in the pulp (yellowish fleshy mesocarps) of the fruits were determined.

To avoid the contamination of the must in ethanol production refineries, the use of antibiotics is one of the main preventive treatments. Thus, there is a risk of antibiotic residues carry over from yeast to animal feed.

A fast and simple method for the determination of 62 veterinary drugs in feedingstuffs was developed, optimized, validated, and applied to real samples. Sample preparation was based on a pressurized liquid extraction method using a hard cap coffee machine, which was compared to a commercial pressurized liquid extraction system. Extraction was performed with diatomaceous earth, acetonitrile (20%), and formic acid (0.

The major phenolic composition (tannins, flavonoids, flavonols, ortho-diphenols, total phenolic content), antioxidant (ABTS and DPPH) and reducing capacities (FRAP and total reducing capacity), antimicrobial effects and inhibition of α-amylase/α-glucosidase were measured. Phenolic compounds were also determined by LC-ESI-MS/MS.
