Sensory optimization of natural sweetener blends for sugar-like taste profiles

Overview

This solution addresses a critical challenge in the food and beverage industry: reducing added sugar content without sacrificing taste. Natural non-nutritive sweeteners such as steviol glycosides, mogrosides, and allulose each carry distinct flavor characteristics, including bitterness, metallic notes, and aftertaste, that limit their standalone use. The research team hypothesizes that carefully designed blends of these natural sweeteners can produce a sugar-like sensory profile by leveraging the molecular structure, solubility, and hydrodynamic volume of each sweetener and their interactions with co-ingredients in beverage systems.

The offering centers on systematic sensory evaluation to identify optimal sweetener combinations for diverse beverage applications, supporting industry efforts to meet consumer demand for reduced-sugar products.

Technical specifications

Research approach:

• Temporal sensory profiling of steviol glycosides individually and in blends with each other, allulose, and sucrose at equivalent sweetness levels (11% sucrose equivalence)
• Model solution testing to identify top-performing sweetener blends compared to sucrose alone
• Polarized Sensory Positioning (PSP) with approximately 60 naive consumers to determine which blends most closely match the sensory profile of sucrose
• Evaluation across multiple flavor applications, with optional carbonation testing
• Assessment of non-sweet side-tastes including bitterness, metallic notes, and aftertaste to minimize undesirable sensory attributes

Key capabilities:

• Expertise in temporal sensory methodology, individual consumer differences, and genetic variation in taste perception
• Established protocols for evaluating non-nutritive sweeteners including AceK, RebA, and RebD
• Access to sensory science facilities and equipment required for controlled consumer testing
• Flexible application testing across diverse beverage matrices and flavor systems

Technology readiness level

This research program is at an advanced validation stage. The principal investigator has extensive published expertise in temporal sensory profiling and non-nutritive sweetener evaluation. The methodology builds on existing scientific literature demonstrating that sweetener blends outperform single sweeteners in matching sucrose profiles, while addressing identified knowledge gaps regarding steviol glycoside blends, allulose combinations, and temporal side-taste characterization. Future validation steps include identifying top-performing blends through model solution testing and confirming consumer preference through polarized sensory positioning studies.
