The phenolic composition, antioxidant capacity and bioaccessibility of the minerals thirteen honey samples from nine different species stingless bees (Meliponinae) were determined in this study. Twenty-six compounds found. major salicylic acid (8.02–94.8 μg 100 g1), p-coumaric (4.54–64.3 naringin (4.00–32.0 g1) taxifolin (12.0–1920 g1). Moreover, presence mandelic acid, caffeic chlorogenic rosmarinic aromadendrin, isoquercetrin, eriodictyol, vanillin, umbelliferone, syringaldehyde,...

The study systematically investigated the nutritional potential of two different growing populations Sarcocornia ambigua (salt-tolerant) in terms nutrients, bioactive compounds, and antioxidant activities. results revealed that moisture content represented largest single component (88.15% 88.57%) proximate composition both samples S. ambigua. mineral present highest amounts (on a fresh matter basis) was sodium, followed by potassium, magnesium then calcium. activity for measured DPPH ranged...

This study evaluates the nutritional potential of Sarcocornia ambigua as new a source minerals. The mineral concentrations two different growing populations (natural occurrence and irrigated) S. were evaluated using inductively coupled plasma mass spectrometry. In all samples, present in highest amounts was potassium (K) (19–24 μg g−1), followed by magnesium (Mg) (8.6–14 g−1) then calcium (Ca) (2.6–4.0 g−1). addition, vitro bioacessibility assay demonstrated that very high fraction (65–80%)...

This study reports the development and validation of a fast capillary electrophoresis method for cation determination in honey samples classification by geographical origin using Principal Components Analysis (PCA). The background electrolyte (BGE) was optimized Peakmaster® software, which evaluates tendency analytes to undergo electromigration dispersion BGE buffer capacity conductivity. final composition defined as 30 mmol L−1 imidazole, 300 acetic acid 140 Lactic acid, at pH 3,0,...

Lead, known as a metal with high neurotoxicity to children, cadmium, which is carcinogenic and bioaccumulative contaminant, arsenic, class 1 according the International Agency for Research on Cancer, are toxic elements (TEs) whose relevant route of exposure may be diet. We determined bio-accessible fraction lead, arsenic from diet preschool children two day care centers (DCC). A cross-sectional study was conducted 64 one–four-year-old DCCs where 24-h duplicate samples were collected. The...
