Abstract


Penambahan sorbitol dalam biji kopi akan berdampak terhadap perubahan yang terjadi selama penyangraian. Perubahan yang paling nampak ialah karakteristik fisik biji kopi. Penelutian ini bertujuan untuk mempelajari pengaruh pemberian sorbitol dalam biji kopi terhadap perubahan fisik biji kopi arabika dan robusta selama penyangraian. Penyangraian dilakukan pada tiga tingkat sangrai (light, medium, dan dark). Sorbitol ditambahkan dalam biji sebanyak 10% (b/b). Hasil penelitian menunjukkan bahwa penambahan sorbitol dalam biji kopi arabika dan robusta dapat meningkatkan rendemen, densitas, kadar air, densitas dan kecepatan kenaikan suhu sangrai. Nilai seluruh parameter pada varietas robusta dan arabika setelah ditambahkan sorbitol menjadi setara dibandingkan perlakuan tanpa sorbitol. Peningkatan tingkat sangrai pada biji kopi yang ditambahkan sorbitol cenderung tidak mempengaruhi perubahan nilai rendemen, densitas dan kadar air biji kopi sangrai.
