Abstract

ABSTRAKTeh diklasifikasikan menjadi 3 jenis yaitu teh hitam, teh hijau dan teh putih. Teh mengandung senyawa kafein yang dapat bermanfaat dan merugikan bagi tubuh. Senyawa kafein dalam teh dapat dipisahkan dengan metode ekstraksi cair-cair menggunakan kloroform dan penambahan CaCO3. Penentuan kadar kafein menggunakan metode spektrofotometri UV diukur pada panjang gelombang 275 nm. Kadar kafein dipengaruhi oleh suhu dan waktu penyeduhan. Semakin tinggi suhu dan lama waktu penyeduhan, kadar kafein dalam teh semakin meningkat. Kadar kafein dari berbagai jenis teh dari kadar yang tinggi ke rendah berturut-turut yaitu serbuk teh hitam, teh putih dan teh hijau dengan suhu penyeduhan 95áµ’C selama 10 menit.Kata Kunci: Teh hitam, teh hijau, teh putih, kafein, spektrofotometri UVABSTRACTTea is classified into three type, which are black tea, green tea and white tea. Tea contains caffeine compound that can be beneficial and harmful for the body. Caffeine compound in tea can be separated by liquid extraction method using chloroform and addition of CaCO3. The determination of the caffeine content measured by UV spectrophotometry at 275 nm. Caffeine level is influenced by temperature and brewing time.
