What Are the Benefits of Qualitative DA?
Qualitative Descriptive Analysis refers to a set of methods that aim to summarize the sensory characteristics of products using technical language.
The highly trained sensory panel must comprehend advanced holistic descriptive concepts (e.g., balance and blend, fidelity, degree of difference, sensory quality) to provide the guidance and strategic insights needed for many innovation, development and maintenance initiatives
Traditional Descriptive Analysis leverages a panel of expert assessors to detect, describe and quantify products sensory properties. Assessors use a detailed lexicon and a rating scale (both need extensive training), to provide detailed documentation of products’ attributes and their intensities. The task is quantitative in nature, leading to profiles that can be statistically compared both at the attribute level and overall.
However, diverse needs require diverse methods. As a result, qualitative approaches to descriptive analysis have emerged and gained in popularity.

Control Supplier 1 Supplier 2Degree of Difference -- 3.0 7.0Qualitative feedback Sensory Description:
• mixed berry (blackcurrant, strawberry, blueberry, raspberry)
• Stone fruit undertones: apple
In comparison to Control:Slight flavor differencesLower total IntensityFlavor close in character to control sample
No textural differences
In comparison to Control:Large flavor differencesMuch lower total intensityMuch higher sweet aromatics Lower mixed berry notesLess complex berry character New note: unique grapefruit note
Moderate texture Differences:Higher viscosity
Recommendations PASS FAIL – Improvement needed
Prototype 1 - Positive feedback overallOverall Feel / ComfortFuzzy (short fuzz) & soft, slightly rougher than most
other samples Thick (although less than most other samples)Not as smooth / slippery as mostPaper feel~ Some lint X Hard to tear from rollControl in use N/A – appropriate level of controlHand protectionWet spill – Protects hand in use (no wet through) Sticky mess - Protects hand well : no tear or slipping Cleaning performance Wet spill: effective, absorbent, no wetness left behindSticky mess – cleans well, nothing left behind
Prototype 2 - Concerns for tear, lack of absorbency, poor hand protection and low cleaning performanceOverall Feel / Comfort~ Among the thinnest in the set, least cushy in the setX Least soft and cushyX Tear
Control in use~ Tears so easily, it does not provide adequate controlHand protectionX With wet spill - Tears way too easily when wetX With sticky mess - Wetness goes through and through Cleaning performance X Leaves area still wet after first wipe (wet spill)X Poor ability to clean, leaves stuff behind (sticky mess)
A manufacturer of paper towels wishes to screen upstream technologies to assess impact on the sensory features of the finished prototypes. An expert Handfeel / Skinfeel panel provides qualitative feedback on each prototype. Data supports the selection of a subset of samples for in-home placement with consumers.

Findings: Paper Towel Prototypes features are summarized individually and / or qualitatively mapped together:
Context:
A fast casual dining restaurant wants to ensure that all local suppliers provide ingredients and products aligned with internal sensory specifications to qualify as approved vendors. Qualitative DA is used to understand sensory differences between approved vendor samples (Control) and new suppler submissions (Test). Feedback is needed to move products needing revision closer to approved vendor sensory profiles.
Context:
Findings: Highlighting key differences between a Control and Suppliers Submissions for Berry Beverages
Guidance: Differences are small yet noticeable among the samples.
Prototypes offer directional advantage in: cleaning performance, comfort/softness, hand protection/control, & Residue/Fuzz left behind
Viable technologies to explore with consumers: Prot. 1 (Cleans & Protect); Prot. 3 (Cleans / Comfort); Prot. 2 (Maybe - Low Clean - but no fuzz)
Using the Qualitative Descriptive Snapshot Approach, the panel first describes a control sample (or space). Each test samples is then rated for overall difference
Guidance: Supplier 1 passed: improvement opportunity exists in enhancing slightly total intensity without changing character.
X Supplier 2 fails: it is encouraged to increase mixed berry notes (by adding blueberry, raspberry and currant notes), lower sweet aromatics (vanillin) and omit the grapefruit note. Lowering viscosity would also be beneficial
Action Standard - Based on stakeholder risk profile, DOD cut-off is established at DOD = 3.0 or less.
