Abstract

: Torbangun leaves (Coleus Amboinicus) contains iron (zinc), carotenoids, flavonoids, polyphenols and antioxidants. Torbangun tea leaves were produced from a drying process of Torbangun leaves at a temperature of 500C for 3 hours. The purposes of this research are: (1) to test the preference of the Torbangun tea leaves by the panelists and (2) to determine the nutritional value and antioxidant's activity of Torbangun tea leaves that are most liked byt the panelists.The preference test of the Torbangun tea leaves has been done by 25 panelists.The experimental design used is a Randomized Block Design (RBD) with two treatment factors, which are the drying temperatue (T) consisting of three levels, namely 45 ° C (t1), 50 ° C (t2), 55 °C (t3) and the time of drying (W) which consists three levels, 2 hours (w1), 3 hours (w2), and 4 hours (w3). Preference test has been done on the flavor, color and taste of 27 samples of Torbangun tea leaves and the most liked sample by the panelists was analyzed on it's moisture content, ash content, the level or the content of antioxidant and it's activity, and polyphenol content. The results of this research showed that t2w2 treatment (the drying temperature: 50 0C, and the drying time: 3 hours) is most liked or preferred by the panelist. The nutritional valueof the Torbangun leaves consist of the water content 11,32 %, ash content 7,88 %, polyphenol 17,12 %, antioxidant's activity 18,033 % and the content of antioxidant is 877,67 mg/g BHA.
