KARAKTERISASI SERBUK JENIS TEH HITAM METODE CTC (CRUSHING TEARING CURLING)

Tea is a commodity that contains antioxidant ingredients, derived from the
tea plant (Camellia sinensis) from the Theaceae family. The types of tea produced at the Wonosari Lawang Tea Factory can be divided into 3 types of quality, namely quality I: Broken Pekoe 1 (BP 1), Pekoe Fanning 1 (PF 1) in good young tea leaves produced from the shoots (peko) plus 2 -3 young leaves, because these young leaves are rich in polyphenolic compounds, caffeine and amino acids., Pekoe Dust (PD), and Dust 1 (D 1), quality II: Fanning (FANN), and Dust 2 (D2) as well as the local quality of Broken Mixed CTC (BMC).
The research design used in this study was RAL (Completely Randomized Design) which was arranged simply with 3 treatments. The method used in this research is experimental method. The factor used was the type of CTC black tea quality. = CTC Black Tea with Pekoe Fanning 1 (PF 1) quality, = CTC Black Tea with Dust 2 (D2) quality, and = CTC Black Tea with Dust 2 quality Broken Mixed CTC (BMC). In accordance with SOP (Quality and Safety Standards for Black Tea Products) , 2021 which refers to SNI No. 1902 – 2016, antioxidant activity using the RSA (Radical Scavenging Activity) DPPH method, and color intensity using a color reader. Moisture content, pH, and organoleptic.
The results showed that CTC black tea had antioxidant activity ratings, starting from the highest, namely BMC (Broken Mix CTC) with 38.187 ppm, D2 (Dust 2) with 38.525 ppm, and PF1 (Pekoe Fanning) with 54.907 ppm.
