Embodiment 1

[0021] A kind of preparation method of asparagus tea, concrete steps are:

[0022] (1) Select fresh organic asparagus tender stems as raw materials, and cut them into asparagus discs with a thickness of 2-3mm and a diameter of about 30mm with a cutting machine after sorting, cleaning and draining;

[0023] (2) Place the cut asparagus discs in a vacuum glass dryer for drying, wherein the cooling in the glass drying process requires the product temperature to drop rapidly to -25°C for 33 minutes, the vacuum degree is 40Pa, and the heating temperature is 50°C, drying time is 24h, sublimation to obtain asparagus tea.

Embodiment 2

[0025] A kind of preparation method of asparagus tea, concrete steps are:

[0026] (1) Select fresh organic asparagus as raw material, after sorting, cleaning and draining, cut into asparagus discs with a thickness of 2-3mm and a diameter of about 30mm with a cutting machine;

[0027] (2) Place the cut asparagus discs in a vacuum glass dryer for drying, wherein the cooling in the glass drying process requires the product temperature to drop rapidly to -24°C for 35 minutes, the vacuum degree is 50 Pa, and the heating temperature is 40°C, drying time is 26h, sublimation to obtain asparagus tea.

Embodiment 3

[0029] A kind of preparation method of asparagus tea, concrete steps are:

[0030] (1) Select asparagus tender stems as raw material, after sorting, cleaning and draining, cut into asparagus discs with a thickness of 2-3mm and a diameter of about 30mm with a cutting machine;

[0031] (2) Place the cut asparagus discs in a vacuum glass dryer for drying, wherein the cooling of the glassy drying process requires the temperature of the product to drop rapidly to -28°C for 30 minutes, the vacuum degree is 40Pa, and the heating temperature is 55°C, drying time is 22h, sublimation to obtain asparagus tea.

Abstract

The invention provides a method for preparing asparagus tea, the preparation method is: drying the cut asparagus discs in a glassy state in vacuum, wherein the temperature drop in the glassy state drying process requires the product temperature to drop rapidly to -24-28°C , the time is 30-35min, the vacuum degree is 40-50Pa, the heating temperature is 40-55°C, and the drying time is 22-26h. Asparagus tea is obtained by sublimation. When the obtained asparagus tea is soaked in water for more than 5min at a temperature above 25°C The dissolution rate is greater than 70.26 in mg / L; this method does not add any additions during the drying process, which can greatly retain the original color, shape, smell, good taste and other food sensory qualities and nutritional components of fresh asparagus, and can improve the quality of asparagus. The dissolution of nutrients in tea has great market development value.

Description

technical field [0001] The invention relates to a preparation method and application of a beverage, in particular to a preparation method and application of asparagus tea. Background technique [0002] Asparagus is a kind of rare vegetable with excellent taste. Its scientific name is Shi Diaobo. It is a perennial herbaceous plant of Asparagus in the family Liliaceae. It is native to the Mediterranean Sea and is now widely planted in my country. Asparagus is rich in potassium ions, which play an important role in the prevention and treatment of cancer and heart disease. In addition, asparagus is rich in dietary fiber, contains essential amino acids, minerals and other nutrients, and contains saponins, flavonoids and other biologically active ingredients, which have various biological functions such as anti-aging , is listed as "one of ten famous dishes" and "the first anti-cancer fruit and vegetable" in the world. [0003] At present, asparagus in my country is mainly eaten...
