Thaumatin production and sensory optimization for sugar reduction in beverages

Overview

Startup Thauma is advancing the industrial production and sensory optimization of Thaumatin, a naturally derived sweet protein extracted from the arils of Thaumatococcus daniellii. Thaumatin is currently the only globally approved sweet protein and offers a safe, healthy, high-intensity alternative to sugar. Despite its strong market potential, two key challenges limit its widespread adoption: difficult extraction from polysaccharide-rich arils and sensory limitations including delayed sweetness onset and a lingering liquorice-like aftertaste at high concentrations. Startup Thauma is addressing both challenges through optimized extraction methods and protein engineering to align Thaumatin's taste profile closer to sugar, enabling broader sugar replacement in beverages.

Technical specifications

Key research and development areas:

• Extraction and purification: Development of scalable methods to overcome the gel-like polysaccharide matrix of arils, increasing yield for cost-effective industrial production
• Sensory characterization: Evaluation of sweetening potency, temporal profile, bitterness masking, and liquorice aftertaste through cellular assays, sensory analysis, and TAS2R receptor interaction studies
• Solubility and stability assessment: Testing under acidic pH conditions, high temperatures, and storage conditions relevant to beverage formulations
• Quantification methods: Development of analytical techniques including HPLC and antibody-based immunological assays
• Protein engineering: Enzyme treatments to reduce sweetness intensity, accelerate onset, or shorten the duration of sweet sensation
• Variants research: Identification of natural Thaumatin variants and mutagenesis approaches for optimized sensory profiles
• Protein design: Computational (in silico) modification of Thaumatin in collaboration with a key partner

Strategic advantages:

• Established agricultural operations and sustainable partnerships in Ivory Coast, supported by deep regional expertise
• Multidisciplinary board with expertise in biotechnology, research, production, and African development
• Incubation at AgroParisTech, a leading French engineering school

Technology readiness level

The project is at an early-to-mid stage of development. A comprehensive literature review has confirmed Thaumatin's promise as a sugar reduction candidate due to its favorable organoleptic properties, solubility, and stability under acidic pH and thermal treatments. Because Thaumatin is already market-approved, integration pathways into beverage product lines are expected to be expedited. Short-term objectives focus on characterization, solubility assessment, quantification, and extraction method development. Mid-term goals center on protein engineering and variants research. Long-term plans involve computational protein design. The research hypothesis will be rigorously validated through ongoing global research collaborations.
