The effect of chlorogenic acid from green coffee as a natural antioxidant on the shelf life and composition of hazelnut paste.

In this study, the effect of chlorogenic acid obtained as an antioxidant from Green Coffee Extract () on the shelf life of Hazelnut Paste () was investigated at 4, 25, and 40 °C for 3 months. The analysis of variance showed that the effect of (Additive Ratio) × (Temperature) × (Storage Time) interaction on Peroxide Number (), tocopherols, and phenolics () of mixtures was found to be significant ( < ). factor on Hunter L*, a*, and b* color values, -radical scavenging activity and antioxidant activity (), factor on oleic/linoleic acid ratio (), and and interactions on free fatty acid were more effective ( < ).

Effects of lyophilized black mulberry water extract on lipid oxidation, metmyoglobin formation, color stability, microbial quality and sensory properties of beef patties stored under aerobic and vacuum packaging conditions.

The objective was to determine the effects of different concentrations of lyophilized black mulberry water extract (BMWE) on lipid oxidation, metmyoglobin (MMb) formation, color stability, microbial quality, and sensory properties of aerobic (AP) and vacuum (VP) packaged beef patties during 15 days of chilled storage. Compared to control, incorporating of BMWE decreased (P < .01) the pH, thiobarbituric acid reactive substances (TBARS), MMb, and hue angle values of both AP and VP beef patties, while improving the redness (a*) and chroma values (P < .

Evaluation of the microelement profile of Turkish hazelnut (Corylus avellana L.) varieties for human nutrition and health.

In this study, the levels of boron (B), cobalt (Co), copper (Cu), chromium (Cr), iron (Fe), lithium (Li), nickel (Ni), selenium (Se) and zinc (Zn) microelements in 16 hazelnut samples were determined by inductively coupled plasma mass spectrometry and atomic absorption spectroscopy after microwave digestion, and are discussed for human nutrition and health. Significant differences were observed between the microelement contents of the 16 varieties (P < 0.01).

Rotavirus infection in children with acute diarrhea as detected by latex agglutination, ELISA and polyacrylamide gel electrophoresis.

We examined prospectively, stool specimens from 135 children, 0 to 3 years old, referred for fever, abdominal pain, vomiting and/or acute diarrhea. Rotavirus antigens were detected from fecal samples by latex agglutination (LA), ELISA and polyacrylamide gel electrophoresis (PAGE). Rotavirus antigen positivity by Latex, ELISA and PAGE were 15, 55%, 12.

Clinical and immunological effects of Newcastle disease virus vaccine on bovine papillomatosis.

Newcastle disease virus (NDV) has antineoplastic and immunostimulatory properties, and it is currently being clinically tested in anticancer therapy. In order to analyze the immunostimulatory effects of NDV on bovine papillomatosis, we inoculated 14 cows subcutaneously with an attenuated vaccine containing the LaSota strain of NDV (LS-NDV). Four cows with papillomatosis served as controls.

Serum concentrations of tumor necrosis factor-alpha in neonatal calves with presumed septicemia.

This study was performed to determine the concentrations of tumor necrosis factor (TNF) in the serum of neonatal calves with presumed sepsis and determine the correlation between serum concentrations of TNF and the severity and outcome of disease. Thirty-five sick calves < 30 days old that suffered from enteritis, respiratory disease, or both were considered suitable for inclusion in this study by satisfying clinical and laboratory criteria suggestive of septicemia. At admission, blood samples were collected from all calves to determine the prevalence of high concentrations of TNF.
