Abstract This study aimed to evaluate the relationship between salinity in the performance of marine shrimp Litopenaeus vannamei and halophyte plant Sarcocornia ambigua in an aquaponic system with biofloc. The experiment was conducted for 57 days, and four treatments were evaluated: 8 psu (practical salinity unity), 16 psu, 24 psu, and 32 psu, with three replicates. Each experimental unit consisted of an 800 L tank for shrimp rearing, a 40 L settling chamber and a hydroponic bench of 0.3 m2 of p...

Abstract The objective of this study was to investigate and quantify the composition phenolic, reducing capacity, the free radical scavenging activity, as well as, the anti-inflammatory effect evaluated against lipopolysaccharides-stimulated RAW264.7 macrophages through modulation of inflammatory mediators, in eight stingless bee honey types (Meliponinae) from southern Brazil. Stingless bee honey did not show to be cytotoxic at the tested concentrations (1-100 µM) and also reduced nitric oxide a...

The aim of the study was to identify, via headspace solid phase microextraction and gas chromatography–mass spectrometry, volatile compounds in eight no processing Apis mellifera L. honey samples produced in the state of Santa Catarina, Brazil, and monitor their stability over 540 days of storage at 20 ± 4 °C, searching for possible degradation indicators compounds. The result of the initial analysis showed the presence of 32 volatile compounds and 24 were selected for the evaluation of the beha...

Abstract The dataset showed in this manuscript belongs to the investigation of the Southern-Brazilian geopropolis of stingless bees. Stingless bees are native species of insects from tropical areas; they produce honey, pollen and geopropolis that is composed of a mix of vegetal extracts, digestive enzymes, and mostly by soil. Used in folk medicine as antiseptic, antioxidant and antimicrobial agent, the composition is due to bee species, climate changes, local flora, and soil type. Moreover, the ...

Yellow guava (Psidium cattleianum Sabine) has received considerable attention in the last years because of their high content in bioactive compounds with potential application in food and pharmaceutical industries. In this regard, this study aimed to investigate the phenolic compounds of three edible ripening stages of yellow guava fruits after acidic hydrolysis by liquid chromatography-tandem mass spectrometry (LC-MS/MS) and their antioxidant capacity. Among the 23 phenolics quantified, catechi...

Abstract Geopropolis is a stingless bee product compose mainly by soil, presenting complex composition geopropolis has bioactive compounds that will depend on geographical characteristics as well bee species, changing their chemical and biological properties. Thus the study aims to evaluate the solubility and chemical stability of geopropolis extracts, through radical capture capacity and reducing capacity. Besides, analysis of free and bonded phenolic compounds, and mineral composition. Geoprop...

Abstract Aliphatic organic acids (AOA) make a strong contribution to flavor, taste, acidity, pH and electrical conductivity. In this paper, a new and fast capillary electrophoresis method was developed and validated to determine 14 AOA simultaneously in bracatinga ( Mimosa scabrella Bentham) honeydew honey and floral honey. Separation of fourteen compounds occurred in 9 min using glyoxylic acid as an internal standard, and the background electrolyte was comprised of phthalic acid (20 mmol L −1 ,...
