The adsorption kinetics exhibited by selected charge mutants of T4 lysozyme at
silanized silica surfaces were monitored with in situ ellipsometry. Mutant lysozymes were
produced by substitution of lysine (Lys) with glutamic acid (Glu). Each substitution
resulted in a decrease in the net charge of the protein by 2 units....
Four years of daily weather observations from Central Tunisia were available for testing the application of the Penman Equation to estimate reference evapotranspiration in the arid climate of Central Tunisia. The data included minimum and maximum temperature, minimum and maximum relative humidity, 24-hour wind run, and lysimeter measurements of reference...
Effects of moisture content, pH, and salt concentration on dynamic rheological properties and gel fracture quality of Pacific whiting surimi were investigated. Torsion tests showed that shear stress decreased rapidly and strain values decreased gradually as moisture concentration increased. As pH increased, fracture shear stress and strain values increased, whereas...
The effect of salt (0, 0.9, 1.7, 2.5%) and pH (range 4
to 10) on surimi gels made from Pacific Whiting (Merluccius
productus) was investigated. Gel-forming ability was measured
by the torsion test. In general, surimi gels
increased in gel strength with increased pH. Breaking shear
stress increased to a...
Adsorption kinetic data recorded for α-lactalbumin, β-casein, β-lactoglobulin, bovine serum albumin and lysozyme at silianized silica surfaces of low and high hydrophobicity, along with a simple model for adsorption and surfactant-mediated elution of protein, were used to analyze the removal of each protein by sodium dodecylsulfate (SDS) and dodecyltrimethylammonium bromide...
The validation and potential use of mathematical models to estimate the
shelf-life of refrigerated food exposed to temperature abuse and basing such
estimations on microbial growth was analyzed. Combined heat transfer, microbial
growth models, and non-parametric statistical procedures formed a computer-based
predictive tool to assess shelf-life and estimate the accuracy...
