| dc.description.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. | en_US |
