Abstract: The present invention provides a method of manufacturing artichoke tea comprising the steps of separating leaf stems, drying the leaf stems at low temperature and performing fermentation, forced-ripening and sugar-preserving processes on the leaf stems of the artichoke. The present invention utilizes the separation to remove the leaves from the leaf stems of the artichoke such that the origin of the taste of bitterness is removed along with the leaves. The leaf stems of the artichoke further undergo drying and fermentation processes such that the water is removed therefrom while preserving the nutrients of the artichoke therein. The forced-ripening and the sugar-preserving processes are further applied to the leaf stems to facilitate the transformation and preservation of the fruitafit-inulin thereof in order to produce a taste of sweetness. The manufactured artichoke tea of the present invention produces no bitterness taste while having nutrients thereof being preserved with enhanced sweet flavor.
