Brief summary
Samples of 4 commercially available bowel cleansing solutions, namely PEG-electrolyte + ascorbic acid (PEG-Asc, Moviprep®, Norgine, UK), PEG-electrolyte (PEG, Fortrans® Ibsen, France), sodium picosulfate/magnesium citrate (SPS, Picoprep®, Ferring, Switzerland), and oral sodium sulfate (OSS, Izinova®, Ibsen, France) were prepared according to the manufacturer's instructions. Descriptive analysis was conducted with trained panelists (N= 14) to create a sensory profile for the solutions and generated attributes were rated on an unstructured 15-cm line scale using the Compusense at-hand® (Guelph, Canada) sensory evaluation software. Acceptability testing was carried out with untrained participants (N=80) and samples were rated on the 9-point hedonic scale. Moreover, a Just-About-Right (JAR) scale was included for the four basic tastes to determine their compatibility with optimum taste/acceptability levels in the products.
Interventions
subjects were asked to assess the sensory profile by tasting the laxative bowel cleansing solutions, namely: Moviprep, picoprep, fortrans and isinova
subjects were asked to assess the acceptability of the laxative bowel cleansing solutions, namely: Moviprep, picoprep, fortrans and isinova

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| rating of sensory attributes | 3 weeks | participants attended 4 training sessions during which they generated sensory descriptive attributes specific for the tasted laxative solutions. In addition, they evaluated the laxative samples by rating generated attributes on a 15-cm unstructured line scale using compusense at-hand sensory evaluation software. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Acceptability Score | 1 week | untrained participants evaluated the laxative samples for acceptability testing using the 9-point hedonic scale. |
| Just about right score | 1 week | Participants evaluated the laxative samples for the 4 basic tastes (saltiness, sourness, sweetness and bitterness) to determine their compatibility with optimum taste levels in the products. |
