Meta-attributes in sensory descriptive analysis

Sara King/ August 23, 2015/ Poster/ 0 comments

Descriptive analysis was conducted by a trained panel on potato varieties, forty in 2010 and forty-four in 2014. The panel evaluated 52 well-defined sensory attributes on line- scales anchored at 0 and 100. Our objective was to determine if there were groups of homogeneous attributes, or “meta-attributes.”

Data collection methods and devices have changed over the years. Research facilities often compare historical to newly obtained data sets however, the question remains; can data be compared when different data collection devices were used? This study determined that descriptive analysis test results are comparable across three different devices, an iPod, an iPad and a computer monitor.

Visualizing micro and macro structures in descriptive sensory training data

Training sessions often yield a limited dataset, which in turn restricts available analyses. Gathering ideal data sets for analysis might be at odds with imperatives of training regimen. Raw data is too voluminous to consider in numerical form. Humans have excellent ability for pattern recognition. Multifunctional graphs can reveal both macro and micro structures in the data.

A system for classifying sensory attributes

Sara King/ September 26, 2006/ Poster/ 0 comments

Descriptive analysis is applied to a diverse range of complex, real-world food and consumer products because the information it provides about those products is unrivalled in its richness. A common lexicon allows the descriptive sensory panel to reference sensory attributes of products undergoing study in a highly specific and consistent manner. When combined with best practices it eliminates ambiguity of

Optimizing descriptive analysis

Sara King/ July 12, 2004/ Oral Presentation/ 0 comments

Descriptive sensory analysis is one of the most powerful tools available to the sensory scientist. Regardless of the individual approach to descriptive analysis there are the common steps of identifying the attributes that describe the product, bringing a panel to agreement on the descriptors that are used, establishing a working scale that captures the range of intensities and practicing the

Feedback calibration: a training method for descriptive panels

Sara King/ July 21, 2003/ Oral Presentation/ 0 comments

Descriptive analysis is one of the most powerful tools available to sensory scientists. However, regardless of the approach being used to analyze the sensory attributes of products, descriptive panels require significant training before the panel members, individually, and the panels collectively, become a reliable sensory instrument. There is great panel-to-panel variability and the training style of panel leaders can have
