Última Characterization of Turkish honeys regarding of physicochemical properties, and their adulteration analysis Ciênc. Tecnol. Aliment. KIVRAK,Şeyda; KIVRAK,İbrahim; KARABABA,Erşan. Abstract This work was conducted to evaluate the quality of 54 honey samples from eighteen different origins from Turkey. Physicochemical properties were examined according to AOAC methods, total phenolic and flavonoid contents by a spectrophotometric method and authenticity of honeys by Combustion Module - Cavity Ring-Down Spectroscopy (CM-CRDS). The microscopic analysis of honey sediment (mellissopalynology) was carried out to identify and count the pollen to provide qualitative indicators to confirm botanical origin. The moisture, electrical conductivity and free acidity of honeys ranged from 15.56 to 18.39%, 0.143 to 2.006 mS.cm-1, 16.05 meq.kg-1 and 34.10 meq.kg-1, respectively. Diastase activity of sideritis honey was found highest. Honeys showed HMF...

Tecnol. Aliment. KIVRAK,Şeyda; GÖKTÜRK,Tolga; KIVRAK,İbrahim; KAYA,Ergun; KARABABA,Erşan. Abstract Aerial parts of Salvia albimaculata Hedge & Hub.-Mor., Salvia potentillifolia Boiss & Heldr. ex Bentham. and Salvia nydeggeri Hub.-Mor. from Soutwest Anatolia, Turkey were evaluated to determine their phenolic compounds and antioxidant properties. According to the ultra performance liquid chromatography with electrospray ionization tandem mass spectrometry (UPLC-ESI-MS/MS) analysis results, caffeic acid (3582.8 ± 2.5 μg/g, 2956.5 ± 4.6 μg/g and 2457.7 ± 3.1 μg/g) and 3,4-dihydroxy benzoic acid (1846.2 ± 3.1 μg/g, 2019.1 ± 2.2 μg/g and 1901.3 ± 1.5 μg/g) were found to be in the highest concentrations in S. potentillifolia, S. albimaculata and S. nydeggeri, respectively. Total amounts of phenolics and flavonoids were determined highest in...

Ano: 2019 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0101-20612019000200423 Development of a rapid method for the determination of antibiotic residues in honey using UPLC-ESI-MS/MS Ciênc. Tecnol. Aliment. KIVRAK,İbrahim; KIVRAK,Şeyda; HARMANDAR,Mansur. Abstract An accurate, reliable and fast multianalyte/multiclass ultra-performance liquid chromatography–tandem mass spectrometry (UPLC–MS/MS) method was developed and validated for the simultaneous analysis of 23 pharmaceuticals, belonging to different classes amphenicols, sulfonamides, tetracyclines, in honey samples. The method developed consists of ultrasonic extraction followed by UPLC–ESI–MS/MS with electrospray ionization in both positive mode and negative mode. The influence of the extraction solvents and mobile phase composition on the sensitivity of the method, and the optimum conditions for sample weight and extraction temperature in terms of analyte recovery were extensively studied. The identification of antibiotics is fulfilled by simultaneous... Tipo: Info:eu-repo/semantics/article Palavras-chave: Antibiotics; Fast method; Honey; UPLC-ESI-MS/MS; Chloramphenicol.
