The instrumental measurement of flavour compounds must ultimately be related back to the sensory perception of flavour.

In addition to providing a longer historical baseline than instrumental measurements, phenological observations provide high temporal resolution of ongoing changes related to global warming.

Different research projects will have different interview conditions, instrumental measurements, data-extraction methodologies, and research aims.

It measured 5.4 on the Richter scale, and is the largest known onshore earthquake to occur in the UK since instrumental measurements began.

Chemical testing requires the extraction or isolation of the compounds of interest, clean up and preparation for instrumental measurement, separation and quantification.

Measuring texture of baked foods Standardised and cost-effective tools to control product quality will be provided following recent research into the instrumental measurement of the texture of baked foods.

This course will look at the effects of the main ingredients, how the biscuit dough and texture can be modified, and assessment methods for biscuit quality including sensory and instrumental measurement.

To measure sea levels prior to instrumental measurements, scientists have dated coral reefs that grow near the surface of the ocean, coastal sediments, marine terraces, ooids in limestones, and nearshore archaeological remains.
