Embodiment 1

[0026] A kind of manufacture method of instant reduced tea powder, comprises the following steps:

[0027] (1) Take 1 kg of Pu’er cooked tea, add 12 kg of pure water to homogenate, place in an ultrasonic extraction tank (the equipment was purchased from Changzhou Extraction Equipment Co., Ltd.), extract for 35 minutes at a power of 20,000 Hz, and control the extraction temperature to 0°C. The concentration of the tea liquid is 8 to 10%, and the 10 micron and 1 micron double filter equipment (Shanghai Filtration Equipment Co., Ltd.) separates and filters the slag. Add 6 kg of pure water to the filtered slag and place it in an ultrasonic extraction tank. Extract under Hertzian power for 20 minutes, the extraction temperature is controlled at 3°C, the concentration of the tea liquid is 5-7%, the 10 micron and 1 micron duplex filter equipment (Shanghai Filtration Equipment Co., Ltd.) separates and filters the slag, and merges twice The filtrate will be the filtrate;

Abstract

The invention discloses a preparation method of instant reduced tea powder. The preparation method comprises the following steps: (1) weighing raw material tea, adding purified water after pulverizingof the tea, carrying out ultrasonic extraction at 0-5 DEG C, and then performing filtering to remove residues to obtain tea liquid with the concentration of 3-10%; (2) filtering the tea liquid obtained in the step (1) through a nanofiltration membrane, performing molecular screening and filtering, performing ultralow-temperature freeze concentration until the solid content is 20-35%, and performing centrifugation to obtain a frozen liquid; and (3) sterilizing and filtering the frozen liquid obtained in the step (2), and then feeding the frozen liquid into a freezing vacuum drier to obtain thereduced tea powder. According to the preparation method of the instant reduced tea powder, effective components in the tea raw material are extracted at a lower temperature, the extraction time is shorter, the extraction rate of the product is increased, and the quality of the tea is improved.

Description

technical field [0001] The invention belongs to the technical field of processing and manufacturing tea drinks, and in particular relates to a method for manufacturing freeze-dried instant reduced tea powder soluble in ice water. Background technique [0002] At present, the focus of the research and development of instant tea is how to effectively collect and preserve the original nutrients and aroma components in the tea as much as possible, so as to further process it into soluble tea powder with the original flavor of the tea. At present, the processing method of this kind of instant tea powder includes the extraction of raw tea and the steps of filtering, concentrating and drying the extract, wherein the extraction mainly includes organic solvent extraction, high and low temperature water extraction, microwave irradiation water extraction and other methods. [0003] Organic solvent extraction needs to recover the solvent, and there are solvent residues in the product, a...
