A preference test for sweet taste that uses edible strips

Area of Science:

• Sensory science
• Human taste perception
• Food science

Background:

• Assessing taste preferences is crucial for understanding food acceptance and dietary habits.
• Traditional methods for taste preference determination can be time-consuming and complex.
• Developing novel, efficient methods for taste assessment is an ongoing area of research.

Purpose of the Study:

• To introduce and validate a novel delivery method for rapid determination of sweet taste preferences in humans using edible strips.
• To compare the efficacy of edible strips with traditional aqueous solutions for assessing sweet taste preference.
• To evaluate the potential applications of this new method in diverse populations and settings.

Main Methods:

• A forced-choice paired comparison approach was employed using edible strips containing varying concentrations of the non-caloric sweetener sucralose.
• The validity of the edible strip method was assessed by comparing results with intensity-matched aqueous sucrose solutions.
• Taste intensity and hedonic responses were measured for both edible strips and sucrose solutions.

Main Results:

• Significantly lower amounts of sucralose in edible strips were needed to identify sweet taste preference compared to sucrose solutions.
• The edible strip method required a similar number of steps to identify preference as the solution method, yielding comparable distribution patterns.
• Sucralose in edible strips produced greater taste intensity and more positive hedonic responses than equivalent sucrose solutions.

Conclusions:

• Edible strips offer a rapid, valid, and practical method for determining sweet taste preferences.
• This novel approach is suitable for young children, clinical populations, and non-laboratory settings.
• The edible strip method holds potential for developing preference tests for other taste stimuli and mixtures.
