Embodiment 1

[0034] Put the fresh kudzu vine into the water to wash, and remove the leaves on the kudzu vine, then cut the kudzu vine after cleaning and removing the leaves into kudzu slices with a thickness of 0.5mm; put 250 pieces of kudzu slices into , 0.2 parts of sodium citrate and 250 parts of water in a color-protecting solution for 1 hour; drain the surface water of the kudzu slices soaked in color protection, and then dry them at a temperature of 115°C for 13 minutes; dry the dried kudzu slices at 155 Stir-fried at ℃ to dry, enhance the aroma, and then weigh and pack after cooling to room temperature. The drying time is 4 minutes. The total flavonoid content of kudzu tea was measured to be 0.24%.

Embodiment 2

[0036] Put the fresh kudzu vine into water and wash, and remove the leaves on the kudzu vine, then cut the kudzu vine after cleaning and removing the leaves into kudzu slices with a thickness of 3mm; Soak for 0.5 hours in a color-protecting solution composed of 0.3 parts of sodium citrate and 250 parts of water; drain the surface water of the kudzu slices soaked in color protection, and then dry at 120°C for 10 minutes; dry the dried kudzu slices at 180°C Stir-fry and dry, enhance the fragrance, and then weigh and pack after cooling to room temperature. The drying time is 3 minutes. The total flavonoid content of kudzu tea was measured to be 0.29%.

Embodiment 3

[0038] Put fresh kudzu vine into water to wash, and remove the leaves on the kudzu vine, then cut the kudzu vine after cleaning and removing the leaves into kudzu slices with a thickness of 2mm; Soak for 0.8 hours in a color-protecting solution composed of 0.25 parts of sodium citrate and 250 parts of water; drain the surface water of the soaked kudzu slices for color protection, and then dry them at 113°C for 11 minutes; dry the dried kudzu slices at 165°C Stir-fry and dry, enhance the fragrance, and then weigh and pack after cooling to room temperature.

Abstract

The invention discloses kudzu tea. The kudzu tea is flake-shaped, and the total flavonoid content of kudzu is 0.21 to 0.29 percent. The method for preparing the kudzu tea comprises the steps of cleaning fresh kudzu, removing leaves, slicing, performing color protection, drying, stir-frying, baking, performing flavor distilling and the like. The waste kudzu is used as a raw material, and the fresh kudzu is soaked in a proper compound color-protecting solution for color protection treatment in the preparation process, so that resources are fully utilized, the pollution of wastes to natural environment is avoided, the browning reaction of kudzu is effectively inhibited, the kudzu tea keeps original color of the kudzu, the visual effect is quite good, the flavonoid content of the kudzu tea is high, the nutritional value is also quite high, more added values are given to the product, and the market competitiveness of the kudzu tea is higher. The preparation method has the advantages of simple process, short flow and convenience in operation and control.

Description

technical field [0001] The invention belongs to the technical field of kudzu processed products and its preparation, and in particular relates to a kudzu tea and a preparation method thereof.
