Arabica coffee drinks in this study were made from three parts of coffee beans are cascara, which is the skin of coffee fruit; green coffee beans; and roasted coffee beans. This beverage product is then packaged and stored in a ready to drink glass bottle. This study aim to determine the shelf life of mixed arabica coffee beverage products, using the ASLT method. Samples were stored under different temperature conditions: 4oC, 27oC and 37oC. The test consists of measuring pH, total dissolved solids (ppm), total sugar (oBrix), total color difference (ΔE) and total plate count (log CFU/ ml). The results showed that during storage occurred to change the physicochemical properties and the number of microbes in the mixed arabica coffee drinks. Each parameter has a different activation energy value. The higher the storage temperature was proven to the smaller the activation energy, which indicates a shorter shelf life. This arabica coffee drink has a shelf life of 4 days if stored at 4oC.
