Impact of water-soluble precursors leaching from green beans on aroma generation during coffee roasting (2018)
Conference Proceeding

In this investigation green Robusta coffee beans were pre-soaked with different time-temperature profiles before roasting in normal conditions and grinding to a standardized particle size. Aroma profile of roasted coffee beans and water soluble precu... Read More about Impact of water-soluble precursors leaching from green beans on aroma generation during coffee roasting.

Age-related changes in oral and nasal physiology and their significance in aroma release and perception (2018)
Conference Proceeding

With aging comes many physiological changes, including those in the oral and nasal cavity, such as impaired olfactory function, reduced salivary flow and compromised dental status and function [1-3]. These changes may impact on aroma release and flav... Read More about Age-related changes in oral and nasal physiology and their significance in aroma release and perception.

Analytical ultracentrifugation in saliva research: Impact of green tea astringency and its significance on the in-vivo aroma release (2018)
Journal Article

Current saliva testing methods rely on cutting edge yet expensive techniques for the detection and analysis of genetic material, proteins and biomarkers for clinical use. However, these techniques are limited in scope and often cannot be used with co...

The impact of nitrogen gas flushing on the stability of seasonings: volatile compounds and sensory perception of cheese & onion seasoned potato crisps (2018)
Journal Article

The impact of natural cheese and onion seasoning on the sensory perception and shelf life stability of potato crisps was studied. This study was carried out to evaluate the impact of nitrogen (N2) gas flushing on the shelf-life stability and sensory... Read More about The impact of nitrogen gas flushing on the stability of seasonings: volatile compounds and sensory perception of cheese & onion seasoned potato crisps.

Characterization of volatile aroma compounds after in-vial cooking of foxtail millet porridge with gas chromatography-mass spectrometry (2018)
Journal Article

Foxtail millet has become popular over recent years for its nutritional value and ecological functions. The aroma of foxtail millet is not well characterized, which is critical for its eating quality and understanding the biochemistry and genetics of... Read More about Characterization of volatile aroma compounds after in-vial cooking of foxtail millet porridge with gas chromatography-mass spectrometry.

Variability of single bean coffee volatile compounds of Arabica and robusta roasted coffees analysed by SPME-GC-MS (2018)
Journal Article

We report on the analysis of volatile compounds by SPME-GC-MS for individual roasted coffee beans. The aim was to understand the relative abundance and variability of volatile compounds between individual roasted coffee beans at constant roasting con... Read More about Variability of single bean coffee volatile compounds of Arabica and robusta roasted coffees analysed by SPME-GC-MS.

Using a combined temporal approach to evaluate the influence of ethanol concentration on liking and sensory attributes of lager beer (2018)
Journal Article

A low alcohol beer evoking similar sensory enjoyment as its higher alcohol counterpart is potentially an attractive proposition to breweries for increased sales volumes, as well as consumers due to health and societal reasons. This study aimed to det... Read More about Using a combined temporal approach to evaluate the influence of ethanol concentration on liking and sensory attributes of lager beer.

Common roasting defects in coffee: aroma composition, sensory characterization and consumer perception (2018)
Journal Article

The demand for high quality and specialty coffee is increasing worldwide.In order to meet these demands, a more uniform and standardized quality assessment of coffee is essential. The aim of this study was to make a sensory scientific and chemical ch... Read More about Common roasting defects in coffee: aroma composition, sensory characterization and consumer perception.

Hyperspectral imaging for non-destructive prediction of fermentation index, polyphenol content and antioxidant activity in single cocoa beans (2018)
Journal Article

The aim of the current work was to use hyperspectral imaging (HSI) in the spectral range 1000-2500 nm to quantitatively predict fermentation index (FI), total polyphenols (TP) and antioxidant activity (AA) of individual dry fermented cocoa beans scan... Read More about Hyperspectral imaging for non-destructive prediction of fermentation index, polyphenol content and antioxidant activity in single cocoa beans.

Near infrared spectroscopy and hyperspectral imaging for non-destructive quality assessment of cereal grains (2018)
Journal Article

Hyperspectral imaging (HSI) combines spectroscopy and imaging, providing information about the chemical properties of a material and their spatial distribution. It represents an advance of traditional Near-Infrared (NIR) spectroscopy. The present wor...
