Abstract

ABSTRAKAntioksidan katekin pada biji kakao diperkirakan bisa mencapai 10%. Senyawa tersebut memberikan banyak manfaat bagi kesehatan. Namun dalam proses pengolahan menjadi bubuk senyawa tersebut banyak mengalami penurunan. Penelitian ini bertujuan untuk mengetahui kadar katekin dan mengevaluasi aktivitas antioksidan pada beberapa produk berbahan utama bubuk kakao di kota Kendari. Kegiatan penelitian diawali dengan survey dan pengambilan sampel produk pada beberapa pasar/toko di Kota Kendari Sulawesi Tenggara. Analisis katekin menggunakan komponen katekin standar (+)-katekin dan evaluasi aktivitas antioksidan menggunakan metode DPPH (2,2-diphenyl-1-picrylhydrazyl). Hasil penelitian menunjukkan bahwa dari 11 produk komersil (yang diberi kode A – K), kadar katekin terendah diperoleh pada produk H sebesar 1,40% dan tertinggi pada produk I (2,72%). Hasil evaluasi aktivitas antioksidan produk dengan kadar katekin tertinggi (produk I) juga menunjukkan aktivitas antioksidan tertinggi sebesar 21,37%. 11 produk komersil tersebut seluruhnya memiliki kadar katekin yang lebih rendah dibandingkan produk bubuk kakao dengan kode L yang diolah dari biji kakao lokal.Kata kunci : katekin, antioksidan, bubuk, kakao, DPPHABSTRACTAntioxidant catechins in cocoa beans is expected to reach 10%. The compounds provide many health benefits. But in the process of processing into powder compounds are plenty decreased. This study aims to determine the levels of catechins and evaluate the antioxidant activity in some of the major products made from cocoa powder in Kendari. Research activities beginning with a survey and sampling of products in some markets / shops in the city of Kendari, Southeast Sulawesi. Analysis of catechins catechin using standard components (+) - catechin and evaluation of antioxidant activity using DPPH (2,2-diphenyl-1-picrylhydrazyl). The results showed that of the 11 commercial products (code A - C), low levels of catechins obtained on H amounted to 1.40% and the highest in the product I (2.72%). The results of the evaluation of the antioxidant activity of the product with the highest catechin content (product I) also showed the highest antioxidant activity of 21.37%. 11 The commercial products all have lower levels of catechins than cocoa powder products with the code L prepared from local cocoa beans.Keywords: catechins, antioxidants, powder, cocoa, DPPH
