Abstract

Bondowoso Arabica coffee is a type of coffee that grows on the slopes of Mount Ijen-Raung. It has a high commercial value and distinctive taste. Coffee processing applications from roasting, grinding, packaging and brewing to storage will affect the quality of coffee. Caffeine is one of the compounds in coffee that contributes to bitterness and has certain pharmacological effects. This study aimed to determine the caffeine content of Bondowoso Arabica coffee harvested on August 2021 which was obtained from Sukosari Lor village with various roast profiles and types of packaging. In this study, Arabica coffee was roasted with light roast, medium roast and dark roast profiles. Then each treatment was mashed to obtain ground coffee. Ground coffee was put in a standing pouch made of polyethylene terephthalate (PET) with a thickness of 75 microns; polypropylene (PP) with a thickness of 100 microns; and polypropylene (PP) with a thickness of 120 microns and then stored for three months. During the storage of first and third months, caffeine levels were measured. Based on the results of the study, the caffeine content was increase along with higher roasting temperature. During the storage process, the caffeine content in ground coffee packaged using PP decreased the most.

Abstract

The coffee roasting keys are temperature and time. Coffee beans have many chemical and physical reactions while the roasting is running. These reactions are characterized by a pattern in the drying and development phases during coffee roasting. This study discussed how roasting affected the characteristics of coffee beans, particularly antioxidant activity and amino acids, and also tried to define the roasting process by describing each roasting phase. The study discussed these characteristics of Java Ijen arabica coffee, which has speciality coffee criteria. The roasting process can increase amino acids and antioxidant activity inside the coffee beans, but the excessive heat and longer duration of roasting can burn the amino acids. Based on this study, the highest antioxidant Activity was found in beans that had been roasted with a total roasting time under 13 minutes, started with charge temperature of 148oC, and released at 190.5oC. The beans that had been roasted with a total duration under 13 minutes, started with charge temperature of 149oC, and released at 184.8oC is the best roasting degree with the highest score on the cup test.
