The recipe of some food products contains dried hen egg white (EW). It is convenient in use and available with a range functionalities as result being stored under different time, temperature moisture conditions following drying. Amyloid fibrils are fibrillary protein structures composed highly ordered stacking cross-? sheets. They can contribute to the foaming gelling capacity EW proteins. We ...

This application note demonstrates the performance of Capto Core 700 chromatography medium (resin) as an alternative for ovalbumin removal in the production of egg-based influenza vaccine. Ovalbumin removal and haemagglutinin (HA) recovery were determined after the Capto Core 700 step in combination with ultrafiltration and diafiltration (UF/DF). The process performance was compared with that o...

1. Pullets were given from 1-d-old diets containing 1-6, 4-1, 8-1 and 12-0 g Mg/kg. Only small effects of these diets on live weight, food consumption, egg number, egg weights or egg-shell thickness were observed except at the highest level (12-0 Mg/kg) which caused diarrhoea and an appreciable lowering of the live weight of growing pullets. A further group was given from point-of-lay a diet co...

Pasteurization at 60 C cannot be used to eliminate Salmonellae from liquid egg white, since this process coagulates the proteins and destroys the functional properties of egg white. Therefore, other means of destroying these organisms have been investigated. These include storage of the dried egg white at 50 to 70 C (Banwart and Ayres, 1956) and irradiation with high voltage cathode rays (Nicke...

A proteomic study of egg white proteins from 2 major poultry species, namely quail (Coturnix coturnix) and duck (Anas platyrhynchos), was performed with comparison to those of chicken (Gallus gallus) through 2-dimensional polyacrylamide gel electrophoresis (2-DE) analysis. By using matrix-assisted laser desorption/ionization time-of-flight tandem mass spectrometry (MALDI-TOF MS/MS), 29 protein ...

Serum concentrations of ovalbumin, beta-lactoglobulin, and antigen-antibody complexes were measured after jejunal administration of milk and raw egg in 6 children with active coeliac disease and in 4 controls. The results did not support the hypothesis of a generalised increase in absorption of antigens from the intestinal lumen in coeliac disease.

The binding of 125I-labeled immunogenic peptides to purified Ia molecules in detergent solution was examined by equilibrium dialysis. We used the chicken ovalbumin peptide ovalbumin-(323-339)-Tyr, which is immunogenic in the BALB/c mouse and restricted to I-Ad. 125I-labeled ovalbumin-(323-339)-Tyr was shown to bind to I-Ad but not to I-Ed, I-Ek, or I-Ak. This binding was inhibited by unlabeled ...

Nano-carbon as lighting source is demonstrated in this paper. The characterized nano-radiation from nano-carbon, excited by different lasers in vacuum, is observed when laser intensity is over a threshold. With lower excitation threshold and smaller white light source, nano-carbon is more applicable to be as lighting system than the others in scientific experiments. White light emission of nano...
