Product Information

The coffee-to-water ratio is significantly associated with mass transfer during the extraction process. Studies show that using a lower coffee/water ratio decreases the titratable acidity/total polyphenol concentration ratio and changes the coffee flavor ( 38). While a high amount of coffee decreases bed permeability, resulting in excessive pressure and possible over extraction ( 17), EY can be defined as a specified component released from the coffee matrix at a given time ( 19). So extraction time is another crucial factor for coffee flavor and quality. Likewise, ultrasound has been proposed as an effective technology to reach higher EY than conventional extraction methods due to faster extraction kinetics, with ultrasonic power as the most critical parameter. Therefore, the UAC conditions, including coffee/water ratio, extraction time, together with ultrasonic power, were optimized by OED. A Chroma meter (SR60, Sanenshi, Shenzhen, China), pH meter (LE438, METTLER TOLEDO, Zurich, Switzerland), and refractometer (LH-Q20, Luheng, Hangzhou, China) were used to measure color ( L, a, b values), pH, and total dissolved solids (TDS) of different coffee extracts, respectively. Extraction Rate of Total Phenols (TPC), Lipids (TL), Proteins (Tpro), and Titratable Acidity (TA)

The final score allows you to qualify the coffee as specialty coffee when it exceeds 80 points. Coffees stored in chambers − 10 °C and 10 °C received notes qualifying them as specialty coffees in the initial assessment, after 3 and after 6 months of storage, and the notes after 9 months are in several cases (− 10 GW, − 10 GW, 10 GN, 10 GW, 10 GW) are close to 80 points.
