Abstract

Background: Snow white chrysanthemum flowers (Chrysanthemum morifolium (Ramat.) Hemsl.) are used in medicine as well as a popular drink. This flower contains phenolic compounds and antioxidants that support health. Even though chrysanthemum flowers are well known in Indonesia, their use as a daily functional food is still not optimal. Objective: To determine the quality and antioxidant activity of snow white chrysanthemum flower tea (Chrysanthemum morifolium (Ramat.) Hemsl.). Method: This research is an experimental study involving chemical, microbiological and antioxidant activity testing of snow white chrysanthemum tea using the 2-2 diphenyl-1 picrylhydrazyl (DPPH) method using a UV-Visible spectrophotometer. Results: Polyphenol content test results 5.4 mg GAE/g extract , water content 3.19%, extract content in water 32.7%, total ash content 7.97%, water soluble ash content 45.4%, acid insoluble ash content 0.16%, water soluble ash alkalinity 2.35%, crude fiber 15.5%, cadmium (Cd) <0.04 mg/kg, lead (Pb) <0.008 mg/kg, tin (Sn) <0.06 mg/kg, mercury (Hg) 0.000049 mg/kg, arsenic contamination (As) 0.000631 mg/kg, total plate count (ALT) 1.5x101 colonies, coliform bacteria 0 APM/g, mold <1; Inhibitory Concentration 50% (IC50) 66.0085 mg/ml. Conclusion: Analysis of the quality of snow white chrysanthemum tea has met the quality requirements for packaged dry tea and has strong antioxidant activity.
