Combining technology, knowledge and insight to understand aroma loss
Experts at our GEA Soeborg site in Denmark have combined the latest gas chromatography-mass spectrometry (GC-MS) technology with decades of in house expertise in every aspect of coffee production, to offer analytical services that can help you to understand both where in your coffee manufacturing process aromatic compounds are lost, and potentially how to minimize that loss.
Here at GEA, our experts have married decades of experience in coffee processing with GC-MS technology to develop a suite of highly accurate analytical services that can provide you with detailed evaluation and quantification of dozens of aroma compounds, and/or aroma balance, at multiple stages of your instant coffee process.
Our different service packages can be tailored to identify and measure up to 50 of the most important aroma components in coffee, and map aroma flow to identify at which of up to 13 points in the process aroma is being lost. We can also make mass balances of aroma in and out of specific process equipment, to provide you with key data for fine-tuning running parameters.
The GC-MS system is equipped with an olfactory port so that human testers can smell the individual aroma components as they pass through the equipment. You might arrange to come to Soeborg and undertake a GC-sniff analysis of your coffee, from which we then generate detailed sniffograms (olfactograms).
The overall results can help you to understand where and why aroma components might be lost or destroyed, perhaps due to high temperatures. And this richness of data may point to ways of optimizing processes so that you can get the most out of your valuable beans and technology investment.
GEA has developed a wet grinding technique for adding Roast and Ground (R&G) coffee to coffee extract. The process preserves the coffee flavor and aromas much more effectively than dry grinding and increases your drying capacity. It’s called MicroWet.
GEA has developed an innovative system that helps to capture and preserve key aroma compounds that are otherwise commonly lost during coffee processing. Our technology is small in footprint but big on results, and is easy to integrate into new and existing GEA coffee lines.
Designed for efficient and scalable extraction of herbal products and coffee
The GEA CARINE coffee extractor system has been specifically designed to deliver the highest possible yield while ensuring the preservation of delicate coffee aroma compounds.
What if your favorite chocolate didn’t require cocoa beans and your coffee was locally produced? As climate disruption, price hikes and ethical concerns hit two of our most beloved indulgences, scientists are reimagining how we produce them – using microbes, not monocultures. The goal: preserve the flavor and properties of coffee and chocolate while minimizing carbon emissions and improving food resilience.
Ports now compete not just on logistics, but on sustainability. At Greece’s Piraeus port, an advanced processing and recovery facility recycles ship waste oil into fuel. Equipped with GEA’s high-performance centrifuges, it sets a new benchmark for state-of-the-art, environmentally responsible port operations.
The 2022 CO2 shortage forced breweries to review their dependency on global supply chains. Many were forced to close, unable to carbonate their products. At its breweries in Germany, OeTTINGER GETRÄNKE is turning its own CO2 into a powerful lever for independence and sustainability – with the help of CO2 recovery technology from GEA.
