Abstract

The invention discloses a preparation method and products of cold-water-made lemon-honey-black tea powder. The preparation method comprises the following steps: selecting fresh lemons, clearly washing the selected lemons, dicing the washed lemons, and mashing the lemon dices; uniformly mixing the mashed lemon dices with the honey and the black tea powder in mass ratio of (3-6): (3-6): 1, carrying out honey-processing, maintaining the pressure at 200-500MPa for 4-15 minutes, adding konjac fine-flour of which the mass accounts for 1-5% of the mass of the mixture into the mixture, homogenizing the pulp, carrying out gradient heating, freezing and vacuum drying, and carrying out smashing, so that the cold-water-made lemon-honey-black tea powder is prepared. The preparation method disclosed by the invention is simple and capable of being applied in industrialized production; moreover, the prepared cold-water-made lemon-honey-black tea powder is good in cold solubility and instant solubility. The brewed tea water is original in flavor and good in taste coordination; thus, the cold-water-made lemon-honey-black tea powder has wide market prospects.

Description
