Non-invasive stripping technology for flavor customization of coconut water

Overview

This technology addresses the challenge of modifying the flavor profile of coconut water without introducing invasive chemicals or additives. By using a closed-loop stripping system driven only by inert carrier gases, the technology selectively removes targeted volatile compounds responsible for unwanted flavors, enabling the production of neutral or customized coconut water products. The approach preserves the natural composition of the beverage while giving producers precise control over its sensory characteristics. Applications include beverage product development, flavor standardization, and clean-label processing where manufacturers seek to reduce or eliminate specific flavor notes without reformulating the entire product.

Technical specifications

Core approach:

• Inert carrier gas is bubbled through coconut water to liberate volatile compounds
• The gas stream passes through a sequence of selective chemical and/or enzyme-based traps
• Traps capture only the unwanted volatile compounds based on functional group reactivity
• Treated gas is recycled back into the product in a closed loop
• Only endogenous compounds plus the inert carrier gas contact the product

Trap design:

• Initial focus on carbonyls and lactones, two functional groups commonly associated with flavor-active volatiles
• Selectivity achieved through traditional chemical methods and enzyme-based reaction systems
• Traps arranged in sequence to achieve layered selectivity for different compound classes
• Trap components are isolated from the final product by the closed-loop system design
• Specific target compounds determined in collaboration with industry partners

System characteristics:

• Laboratory-scale validation platform
• Designed for study of trap selectivity and removal kinetics
• Modular trap configuration allows customization for different flavor targets

Technology readiness level

This is a laboratory-scale proof-of-concept study. The research focuses on validating the selectivity of the trap chemistries and characterizing the kinetics of volatile compound removal from coconut water. The closed-loop system design has been defined, and experimental work will use inert gas recirculation through sequential chemical traps. Specific target compounds for removal will be identified through consultation with industry partners. The next steps involve demonstrating reproducible selectivity and removal efficiency at the bench scale before considering scale-up or pilot trials.
