Embodiment 1

[0026] The processing technology of instant tea paste is as follows:

[0027] ①Choose 1000g fresh vine tea leaves, wash them with clean water, put them in the freezer, and freeze them slightly at -10°C for 1 hour;

[0028] ②After taking it out, put it in the microwave equipment, first use the microwave power of 1000W for 60s; then use the microwave power of 1000W for 30s;

[0029] ③Put the microwave-treated tea leaves in a 100-mesh filter cloth or a drawer cage, and brew them with pure water twice the weight of the tea leaves in a circular manner. During the brewing period, keep the water temperature at 10°C, and the brewing time is 3 hours; after brewing, filter to obtain the brewing solution spare;

[0030] ④ Use 100kHz ultrasonic waves to brew and filter the tea leaves, and ultrasonically treat them at 200V and less than 50°C for 20 minutes, and filter to obtain the first ultrasonic extract; Treat for 60 minutes, and filter to obtain the second ultrasonic extraction solut...

Embodiment 2

[0036] The processing technology of instant tea paste is as follows:

[0037] ①Choose 2000g fresh leaves of vine tea, wash them with clean water, put them in the freezer, and freeze them slightly at -5°C for 2 hours;

[0038] ②Take it out and place it in a microwave equipment, first use a microwave power of 3000W for 30s; then use a microwave power of 300W for 120s;

[0039] ③Put the microwave-treated tea leaves in a filter cloth or a drawer, and brew them with pure water 10 times the weight of the tea leaves in a circular manner. During the brewing period, keep the water temperature at 25°C and the brewing time is 0.5 hours; after brewing, filter the brewing solution for later use. ;

[0040] ④ Use 50kHz ultrasonic waves to brew and filter the tea leaves, and ultrasonically treat them at 100V and less than 50°C for 60 minutes, and filter to obtain the first ultrasonic extract; Treat for 20 minutes, and filter to obtain the second ultrasonic extraction solution;

[0041] ⑤C...

Embodiment 3

[0046] The processing technology of instant tea paste is as follows:

[0047] ① Select 1000g of dried leaves of vine tea, wash them with clean water, put them in the freezer, and freeze them slightly at -8°C for 1 hour;

[0048] ②After taking it out, put it in a microwave equipment, first use a microwave power of 2000W for 50s; then use a microwave power of 800W for 100s;

[0049] ③Put the microwave-treated tea leaves in the mesh filter cloth, and brew them with pure water 6 times the weight of the tea leaves in a circular manner. During the brewing period, keep the water temperature at 20°C, and the brewing time is 2 hours; after brewing, filter the brewing liquid for later use;

[0050] ④Use 60kHz ultrasonic waves to brew and filter the tea leaves, at 100-200V and less than 50°C, ultrasonically treat them for 30 minutes, and filter to obtain the first ultrasonic extract; use 80kHz ultrasonic waves to filter the residue, At ℃, sonicate for 20 minutes, and filter to obtain th...

Abstract

The invention relates to instant tea paste and a processing technology thereof. The technology comprises the following steps: performing light-degree freezing and microwave treatment, mixing with circulating water, ultrasonic extracting, concentrating in low temperature and vacuum, freeze-drying and shaping in vacuum and the like. Through light-degree freezing, more effective ingredients can be extracted and flavor substances and pigment of tea can be reserved. Through microwave treatment, tea cells are broken, which is beneficial to improving extraction efficiency; and the heat generated by microwave treatment is absorbed by ice crystal, thus having no high-temperature reaction on tea and less loss on the flavor substances and the pigments of tea. Mixing with low-temperature circulating water is combined with ultrasonic extracting to realize low-temperature extraction with short extraction time, high extraction yield and high extraction efficiency of effective components in tea up to over 80%, less damage to the original color, flavor and nutrient substances, and better taste. The instant tea paste especially overcomes the defects of easy browning of color of the traditional tea paste.

Description
