A new human pneumovirus, provisionally designated metapneumovirus, was discovered by Dutch researchers. We examined 142 serum samples from the general population aged 1 month to 35 years in Japan for metapneumovirus antibody indirect immunofluorescence assays using metapneumovirus-infected monkey kidney cells. The overall prevalence of infection 72.5%. seropositive rate lowest age group 6 months year and gradually increased with age. All children had been exposed 10 years. results show that...

ABSTRACT A new method was established to estimate the foaming properties of proteins from conductivity foams using a simple apparatus that consisted glass column with cell. close correlation observed between initial and foam volumes heat‐denatured ovalbumins or 11 native proteins, suggesting can be used as measure power. In addition, obtained stability determined changes in volume time also estimated foams. The advantages measurements are determine more simply accurately than currently methods.
Casein was conjugated with dextran and galactomannan in a controlled dry state at relative humidity of 79% 60°C for 24 hr. The covalent attachment polysaccharides to casein confirmed by SDS-PAGE HPLC. emulsifying activity the casein-dextran casein-galactomannan conjugates 1.5 times higher than that casein. emulsion stability 10 improvement these properties reached steady when conjugation polysaccharide done hr state, suggesting rapid formation through Maillard reaction case Compared...

ABSTRACT A method was developed to measure the emulsifying activity and emulsion stability of proteins using a simple apparatus consisting glass column with conductivity cell. significant correlation observed between 10 determined by examined in this paper turbidity Pearce Kinsella (1978). These results suggest that properties can be estimated measuring changes emulsion. The advantages are accurately simply proteins, because directly automatically measures physical constant (that is, conductivity)

Changes to the conformation and functional properties of soy protein caused by mild acid treatment were investigated. When a 2% solution in 0.05 N HCl was heated for 30min at 95°C, protein, including its solubility, emulsifying foaming properties, greatly improved. It found that can be deamidated preferentially without significant cleavage peptide bonds under these carefully controlled conditions dilute (0.05 95°C 30 min).

The surface properties of deamidated gluten were investigated with respect to their conformational changes. helix content decreased curvilinearly its decrease deamidation. tension in proportion the degree On other hand, hydrophobicity increased remarkably emulsifying improved greatly by deamidation, correlating linearly hydrophobicity. From these results, relationships between changes and functional are discussed.
