Abstract

White chrysanthemum (Chrysanthemum morifolium Ramat.) is widely used in medicine, popular drinks and as a functional food. White chrysanthemums are often used as health care products because they contain functional compounds such as phenolic compounds and antioxidant activity. Chrysanthemum is well known in Indonesia, but it has not been utilized optimally in daily life as functional food. This research is done in order to determine the effect of drying using cabinet dryer at temperatures of 40°C, 50°C, and 60°C on physical characteristics such as color and shrinkage, chemical characteristics such as moisture content, total phenol, antioxidant activity and water activity, and sensory characteristics such as color, aroma, taste, after taste and overall as well as the amount of heat required for the drying process. This research is conducted using completely randomized design. The results show that cabinet dryer at 60°C is the best drying method. Characteristics in white chrysanthemum tea are ∆E value is 39,51; long shrinkage value is 23,65%, width shrinkage is 28,46%; water content value is 6,81%; total phenol value is 15,99%; antioxidant activity value is 87,52%; water activity value is 0,25; with color 3,93 (like), aroma 3,30 (neutral), taste 3,03 (neutral), after taste 3,33(neutral) and overall 3,23 (neutral). The heat of drying at 60°C is 2.147,295kJ.

Abstract

Beluntas (Pluchea indica L.) leaf is a plant that has high antioxidant compounds, and mint (Mentha piperita L.) leaf contain mentol compounds which can improve the taste of herbal drinks. In the processing, the drying process can affect the functional content of beluntas leaves and mint leaves. This study aims to determine the effect of drying time and the formulation of beluntas leaves and mint leaves on physical (colour), chemical (moisture content, total phenol, and antioxidant activity), and sensory (colour, smell, taste, and overall) properties and to determine the combination of drying time and the formulation of beluntas and mint leaves that provide the best herbal drink. The experimental design carried out in this study used a Completely Randomized Design (CRD) with a combined factor, drying time and formulation of beluntas and mint leaves. The time variation used is 1.5 hours; 2 hours and 2.5 hours. Various formulations of beluntas leaves and mint leaves used were 1:1, 2:1, and 3:1. The results showed that the treatment of variations in drying time and the formulation of beluntas and mint leaves had a significant effect on physical (a* and °Hue values), chemical (moisture content, total phenol, and antioxidant activity), and sensory (colour) characteristics. The best treatment in making herbal drink from beluntas and mint leaves is with 1.5 hours drying time and the formulation is 1:1.
