The concentrate is useful in tea, beverages or the like by diluting in water, fruit juice or the like. CONSTITUTION: A turnip(Brassica campestris L. subsp. rapa Hook. et And.) is immersed in acidic immersion liquid, cut to a suitable size, extracted in an extraction solvent and concentrated after filtering.
