HEALTH TEA FROM KENAF LEAF AND PREPARING METHOD FOR THE SAME

摘要

Healthy tea with kenaf leaves and a preparation method thereof are provided to facilitate the elution of active ingredients in extraction in hot water by treating the leaves with heat and far infrared ray in a fixed condition, thereby substituting the same for green tea. Healthy tea with kenaf leaves is prepared by the steps of: heating kenaf leaves at 60~100°C for 10~45min; and applying far infrared ray to the leaves at 1.6kw for 10~45min while keeping the temperature at 60~100°C. In the preparation process, large quantities of minerals and antioxidant ingredients are extracted from the kenaf leaves. The extract is especially rich in kaempferols as a polyphenol compound. In addition, the content of physiologically active ingredients in the kenaf leaves is higher than that in green tea leaves.
