Potensi Teh Eceng Gondok (Eichhornia crassipes) Berdasarkan Perbedaan Metode Pengeringan: The Potential of Water Hyacinth Tea (Eichhornia crassipes) Based on Differences in Drying Method

Abstract

Water hyacinth (Eichhornia crassipes) has potential as a raw material for tea that is rich in bioactive compounds. However, the drying method used can affect the quality of the tea produced, both in terms of active compound content and physical properties. Therefore, this study was conducted to determine the optimal drying method to produce water hyacinth tea with good physical quality and bioactive compound content. This study aims to determine the best drying method for water hyacinth tea characteristics. This related research was designed using the Completely Randomized Design (CRD) method, which included three levels of treatment and two replications. The stages in this study are the manufacture of water hyacinth tea powder with IC1 (sunlight), IC2 (roast), IC3 (oven) treatments, the process of serving water hyacinth tea and testing. Testing parameters include yield analysis, moisture content, total ash content, total phenol, pH and hedonic (aroma and color). The best research results were obtained by the IC2 treatment (roasted) with a yield value of 42.2%, moisture content of 6.33%, total ash content of 12.92%, total phenol 184.49 mg GAE/100 grams, pH of 5.85, preferred aroma parameters (4.00) and color that was still not liked by panelists because it scored 2.90.
