By using the desirability function approach and considering superficial colour parameters, O2 concentration, mesophilic counts, browning potential, ascorbic acid and chlorophyll content, the optimum processing conditions were 7.5 min of ultrasonic treatment, 3 min of a heat shock treatment and a citric acid concentration of 1.5%.
Treatment effects were evaluated on weight loss, superficial colour (hue angle (H°) and total colour difference (ΔE)), headspace gas composition (O2 and CO2), overall browning potential, chlorophyll content, ascorbic acid content, mesophilic counts and overall visual quality (OVQ) and optimize the process by means of the desirability function.
All the morphological features previously discussed are preserved and only a moderate increase of the superficial gloss and of the colour saturation can be qualitatively assessed (Fig. 4, specimens labelled P).
The inspiration can be triggered either by direct observation or captured by three-dimensional (3D) digitising techniques to obtain superficial information (geometry and colour).
"This is a great biological example of how traits can be controlled, and what a superficial difference blond hair colour really is," David Kingsley, a professor of developmental biology who led the research, told National Geographic.
Being known only as a colour is a superficial, one-dimensional way to describe a hundreds-of-million strong group with a long and enduring history.
Several of the differences Dr Quintana-Murci detected are in genes for the superficial racial markers of skin colour and hair form.
The reality is that racial categorisations are based on the most of superficial factors such as skin colour – which actually have little to do with one's genetic and ethnic make-up.
Comparative genomics applied to distinct populations of humans has shown that the human species is a genetic continuum, and the differences between populations are restricted to a very small subset of genes that affect superficial appearance such as skin colour.
Referring to the antique, he generally avoided superficial beauty by utilizing deliberately simplified colour and compositions and a schematic, even childlike, rendering of forms and scale.
January 8 , 1680Gaeta, Italy September 1, 1764 Naples, Italy Sebastiano Conca, (born Jan . 8 , 1680Gaeta, Kingdom of Naples [Italy] died Sept. 1, 1764, Naples) late Neapolitan Baroque painter who created great, animated compositions, superficial in content but dazzling in colour and in execution.
