Preparation method of coffee

Abstract

The invention discloses a preparation method of coffee. The preparation method comprises the following steps: a step (1), soaking raw coffee beans for 2-3h; a step (2), steaming the soaked coffee beans at 100 DEG C for 2-2.5h; a step (3), drying the steamed coffee beans; a step (4), baking the dried coffee beans and licorice leaves together for 30-34min, and then grinding the baked coffee beans and the baked licorice leaves into powder, wherein mass ratio of the licorice leaves to the dried coffee beans is (0.3-0.4) to 10; a step (5), performing extraction on the powder with water, wherein the extraction is divided into two stages, the extraction temperature at the first stage is 70-80 DEG C, the extraction time of the first stage is 30-50 min, then the extraction is in the second stage, the extraction temperature at the second stage is 200-220 DEG C, and the extraction time of the second stage is 1.2-2.4h; and a step (6), concentrating extract liquor, and performing spray drying so as to obtain the coffee. The coffee prepared by the preparation method disclosed by the invention contains the component of the licorice, so that the side effects of the coffee to human bodies can be balanced, and the coffee prepared by the preparation method is beneficial to the health of the human bodies.

Description

technical field [0001] The invention relates to a method for preparing coffee.
