QSorter® opens the door to managing the quality and value of green coffee using an unprecedented bean-by-bean biochemical analysis and sorting. This is a significant capability because there is typically much bean-to-bean variation. This is the case e.g. among Arabica coffees in mountainous tropical regions which are mostly hand-picked from trees by smallholder farmers. It is known that visible defects occurring during harvest or processing can be detected by available technologies on the market. However, until now the coffee industry has been unable to address sensory variations, which are not visible on the outside of beans.
Here are some examples of how QSorter® addresses the unsolved challenges of the coffee industry.
Another innovation from QualySense is the ability to select green coffee beans based on a prediction on how the roasting would be at a later stage. This means that such knowledge would be available before the actual roasting happens!
Most of the aromatic qualities which you enjoy in your morning cup are created during the roasting process via a conversion of precursor biochemicals within the green beans. For example, unripe green beans are the result of a lack of an adequate maturing process. A variant of this defect is known as Quakers which stands out as pale in appearance after roasting and bland in taste whereas the rest of the batch can reach the desired roast color.
QSorter® can separate a batch of green beans of any desired size into 2 to 4 fractions according to their predicted degree of roastability. The beans are chosen based on a combination of biochemicals (moisture, sucrose and oil being the predominant ones), which create sub-batches with uniform roasting characteristics. Once separated, the poorly roasted beans can go through a longer roasting process or they can be used in blends of lower quality. Beans with the best composition of roast-relevant biochemicals will often receive an improvement of 1 to 3 Q-grade points. The uniformity of roasting gets vastly improved for all fractions, removing the unripe, burnt and rubbery off-tastes that comes from inhomogeneous roasting.
QSorter® technology is already being successfully used for grain-by-grain quality inspection of rice and peanuts according to accepted industry standards. QualySense’s soon-to-be released Green Coffee Quality Inspection (Q.I.) solution will provide fast and accurate measurement of visible-defects’ count, size, color and moisture statistics of green coffee samples. The digitally generated quality reports from the QSorter® will bring repeatable and reproducible quality assessment to all parties of the value chain.
