The main aim of the present study was the evaluation of proteins and antioxidant potential in ethylene-treated kiwifruit during the first 10 days of ripening. Kiwifruit samples were randomly divided into two groups: treated and untreated. Flesh firmness, sensory value, visual score, free sugars, soluble solids, ethylene biosynthesis, proteins, dietary fibers, total polyphenols and antioxidant p...

Abstract The goal of the present study was to verify quality refrigerated raw milk from dairy properties and also milk, pasteurized Ultra High Temperature (UHT) industries in Vale do Taquari Rio Grande Sul, Brazil. Physicochemical, microbiological composition analysis were carried out, as established by legislation, addition total thermotolerant coliforms psychrotrophic counts three types mesop...

The liquid-liquid extraction of Ti(IV) from perchlorate media using, di(2-ethylhexyl) phosphoric acid (D2EHPA) and 2-ethylhexyl prosphonic acid mono-2-ethylhexyl ester (PC-88A) in toluene as the extractant was studied. Quantitative extraction of Ti(IV) was observed in the lower acidity range of 0.01 to 0.1 mol dm-3 with 0.003 mol dm-3 D2EHPAand 0.01 mol dm-3 PC-88Ain toluene, respectively, and ...

Bio-based furanics can be aromatized efficiently by sequential Diels-Alder (DA) addition and hydrogenation steps followed by tandem catalytic aromatization. With a combination of zeolite H-Y and Pd/C, the hydrogenated DA adduct of 2-methylfuran and maleic anhydride can thus be aromatized in the liquid phase and, to a certain extent, decarboxylated to give high yields of the aromatic products 3-...

This study assessed the potential of near infrared (NIR) spectroscopy as a non-destructive method for characterizing Protected Designation of Origin (PDO) "Vinagres de Montilla-Moriles" wine vinegars and for classifying them as a function of the manufacturing process used. Three spectrophotometers were evaluated for this purpose: two monochromator instruments (Foss NIRSystems 6500 SY-I and Foss...

The aim of this study was to investigate the effect of fenugreek seeds on aspegic induced gastric mucosal ulcer in rats. Forty-eight male albino rats of Sprague Dawley strain were classified into normal control group and five aspirin induced gastric ulcer groups which divided into non treated control (+ve) and treated groups that were drug, fenugreek seeds extract, fenugreek oil and fenugreek p...

The secondary organic aerosol (SOA) yield of βcaryophyllene photooxidation is enhanced by aerosol acidity. In the present study, the influence of aerosol acidity on the chemical composition of β-caryophyllene SOA is investigated using ultra performance liquid chromatography/electrospray ionization-time-of-flight mass spectrometry (UPLC/ESI-TOFMS). A number of first-, secondand higher-generation...

The physico-chemical and microbiological properties of wheat flour samples (type 650) obtained from 7 different locations in the Thrace region (Turkey) were assessed. Totally 142 wheat flour samples were analysed physicochemically in terms of ash, moisture, fat acidity, and protein amounts, and microbiologically in terms of total mesophilic aerobic bacteria (TMAB), Escherichia coli, Bacillus ce...

OBJECTIVE The study was designed to test for the existence of a correlation between the total population of aerobic mesophilic microorganisms in processed raw breastmilk from a human milk bank and the Dornic acidity of that milk. METHODS Two hundred consecutive samples of thawed expressed human breastmilk obtained from human milk bank, prior to pasteurization. Dornic acidity was titrated in t...
