CHEMICAL PROFILE OF GROUND COFFEES IN SOUTH SUMATERA


Abstract
South Sumatra is the largest coffee-producing province in Indonesia. However, many ground coffee products circulating in the market have yet to meet the Indonesian National Standard (SNI) or obtain Geographical Indication (GI) certification. This study aimed to analyze the chemical characteristics of ground coffee from South Sumatra that meets SNI standards, possesses GI certification, and those that are uncertified. Three chemical parameters were examined: moisture content, ash content, and caffeine content. The results showed that the ash and caffeine contents of all six ground coffee samples met the quality standards set by SNI. However, the moisture content of all samples exceeded the maximum limit specified in the SNI for ground coffee, ranging from 7.38% to 9.10%. These findings indicate that although two parameters meet quality standards, improvements in processing or storage practices are still necessary to reduce moisture content and ensure the quality and shelf life of ground coffee.
