SESSION SETUP (facilitator; retain blind-code key separately)
Project / session / date: ____
Sensory lead / tasting safety clearance: ____
Question: equal supplied-ingredient dose / matched in-mouth sweetness / whole recipe comparison: ____
Sucrose reference and concentration with units: ____
Pilot used to set candidate doses / version: ____
Base recipe version / residual sugar with units: ____
Water / pH / heat process / storage age / carbonation: ____
Ingredient identities / glycoside profile / carrier / lots: ____
Supplied-material doses with units (not automatically pure glycoside): ____
Preparation batch IDs: ____
Serving volume / measured temperature: ____
Presentation-order scheme / separate code-key location: ____
In-mouth hold duration and rating window agreed before testing: ____
Nose condition (pinched or unpinched; keep fixed within session): ____
Scale training / reference examples: ____
0–10 intensity scale: 0 = not perceived; 10 = extremely intense.
This proposed scale is NOT the published 15-cm line scale. Do not pool scores.
Palate cleanser / planned rest / recovery criterion between samples: ____
Repeat sample / repeat preparation / repeat session plan: ____
Product-specific decision criteria and analysis plan agreed beforehand: ____

BLIND SAMPLE RECORD (copy one block per assessor and coded sample)
Assessor ID: ____  Session ID: ____  Sample code: ____
Order position: ____  Preparation ID (facilitator link): ____
Actual serving temperature / volume / deviation: ____

In-mouth window: sweetness ____ /10; bitterness ____ /10
Expectoration clock starts when sample is spat out.
At 5 seconds AFTER expectoration: sweetness ____ /10; bitterness ____ /10
At 60 seconds AFTER expectoration: sweetness ____ /10; bitterness ____ /10
No extra sip, rinsing or food until all three observations are finished.
Missing is blank, not zero. Mark a missed cue; do not recreate a timed score from memory.
Actual time / missed cue / other deviation: ____
Descriptors AFTER timed observations (optional): ____
Residual sensation after final observation: ____
Actual cleansing / extra recovery time before next sample: ____

REVIEW (facilitator; retain individual observations)
Repeat consistency / order effects / protocol exclusions with reasons: ____
In-mouth sweetness relative to reference: ____
5-second sweetness and bitterness findings separately: ____
60-second sweetness and bitterness findings separately: ____
Uncertainty / repeat needed / next controlled change: ____
Three moments are not a continuous time–intensity curve.
Do not infer onset, peak or extinction time from these fields.
No universal pass score. No lower-bitterness-to-liking conversion.

Normal-drinking follow-up — SEPARATE SESSION AND DATASET
Session / assessor / sample / preparation IDs: ____
Intended drinking occasion / target consumers: ____
Serving temperature / volume / carbonation / recipe version: ____
Normal drinking, unpinched nose; swallowing rather than expectoration.
If timed: swallowing event definition / observation times: ____
Sweetness / bitterness / other sensory observations: ____
Acceptance or liking question and scale agreed beforehand: ____
Response: ____
Do not pool with expectoration scores.
