Studying the impact of D.I.C. prior to supercritical CO² extraction

July 18, 2022

Dear network, We are running some studies on the impact of D.I.C. prior to supercritical CO² extraction.

The study will aim to demonstrate that pretreating by D.I.C.:

• Improves the final decaffeinated cup taste

•Extraction time by SFE is drastically reduced

This study should lead to a scientific publication.

If you want to push the science on this topic, and :  
• You are a QGrader and are willing to taste some really good / bad coffee samples  
• You work on SFE topics and can bring some tips on the perfect extraction parameters and industrial economics  
• You are a coffee player and can ship us some green coffee beans you usually send for decaffeination, so we could compare the final taste with standard industry processes  
• You work on other decaffeination processes and are willing to study the benefit of adding our D.I.C. pretreatment

Finally, Big up to Dounia BOUCHEKIOUA, from Ecole supérieure de Chimie organique et minérale, who is running the extractions and GC-MS analysis as part of her internship.  
She discovered that D.I.C. treated coffee beans don't explode after SFE, compared to the untreated ones which attacked her.  
First guess: diffusivity is so bad on untreated beans, CO² remained trapped after extraction, released to atmospheric pressure... and kaboom.
