University

Explore a novel method to reduce cocoa bitterness without adding external bitter blockers by leveraging the interaction of natural cocoa compounds with human bitter taste receptors. This approach aims to enhance cocoa flavor naturally, with potential applications in chocolate production.

Overview

Leverage the power of human bitter taste receptors (TAS2Rs) to naturally reduce the bitterness of cocoa. By understanding the complex interactions between cocoa compounds and these receptors, this innovative approach aims to minimize bitterness without the need for exogenous bitter blockers. This method holds significant potential for the chocolate industry, offering a natural solution to enhance cocoa flavor profiles and improve consumer satisfaction.

Technical specifications
  • Human Bitter Taste Receptors (TAS2Rs): The approach involves screening all human TAS2Rs for activation by cocoa bitter compounds.
  • High-Throughput Calcium Imaging: Utilizing advanced imaging techniques to assess receptor activation.
  • Competitive Interaction Analysis: Analyzing mixtures of bitter substances to identify pairs where less effective compounds can reduce the response of stronger bitter agents.
  • Potential Use of Natural Cocoa Compounds: Focus on using intrinsic cocoa compounds to modulate bitterness.
Technology readiness level

Currently at TRL 4, this technology has advanced through basic validation in laboratory settings, demonstrating proof of concept. Further development and testing are planned to advance the technology towards commercial readiness.
