Selective organic coconut compound extraction and removal (SOCCER)
SOCCER is a solvent-based extraction process that selectively removes odor and flavor compounds from coconut water while preserving sugars and electrolytes. Using FDA-approved organic solvents, this method enables production of bland-tasting coconut water for food, beverage, and nutrition applications.
Overview
SOCCER (Selective Organic Coconut Compound Extraction and Removal) is a novel solvent-extraction process designed to selectively remove flavor and odor compounds from coconut water while retaining its valuable sugars and electrolytes. The technology addresses a key challenge in the coconut water industry: producing a bland, neutral-tasting base product that can be customized with desired flavors for beverages, nutrition products, and food applications.
The approach is inspired by decaffeination processes used in the coffee industry, where organic solvents safely and effectively remove target compounds from food products. By exploiting differences in chemical polarity, SOCCER can isolate and extract non-polar flavor molecules from coconut water while leaving behind the polar sugars and electrolytes that give coconut water its nutritional value.
Technical specifications
Core technology:
- Solvent extraction using organic solvents such as dichloromethane (DCM) and ethyl acetate to selectively remove non-polar flavor compounds
- Exploits polarity differences between flavor compounds (less polar) and sugars/electrolytes (more polar)
- Residual solvent removal through heating, ensuring food safety
Key features:
- High selectivity achieved through testing of various organic solvents and adjusting volume ratios of organic to aqueous solutions
- Preliminary testing using a laboratory separatory funnel demonstrated successful extraction of large organic molecules from coconut water samples
- Detection and analysis capability using isothermal gas chromatography and quadrupole mass spectrometry
- Solvent selection prioritized based on FDA-GRAS (Generally Recognized as Safe) status and ease of removal
Potential applications:
- Production of bland or neutral-tasting coconut water for custom beverage formulations
- Food and nutrition product manufacturing requiring flavor-neutral coconut water base
- Integration with existing water testing and analytical systems
Technology readiness level
SOCCER is currently at an early-to-mid stage of development. Preliminary tests have demonstrated proof-of-concept, confirming that dichloromethane can successfully extract large organic molecules from coconut water samples. Further validation is needed to establish the optimal procedure for selectively removing the largest non-polar molecules while retaining sugars and electrolytes. The research team plans to evaluate multiple extraction solvents and refine the process by adjusting solvent-to-water ratios. The estimated timeline for completing this research is approximately nine months.
