Embodiment 1

[0029] Take 0.4 kg of perilla leaves and 1.6 kg of white tea, wash them and grind them. Add a small amount of deionized water to soak for 2 hours. Pour the mixture of perilla leaves and tea leaves into a countercurrent extractor for extraction to obtain a crude filtrate. Use a precision filter membrane containing a polypropylene fiber membrane filter element for preliminary filtration to remove fine particles in the crude filtrate. Then filter with an ultrafiltration membrane with a molecular weight cut-off of 100,000 Daltons to remove macromolecular substances such as pectin, protein, and soluble starch. Then the ultrafiltration permeate was concentrated by a reverse osmosis membrane, and the temperature was controlled at 20°C until a concentrated solution A with a solid content of 5% was obtained. Take half of the concentrated solution A and carry out low-temperature vacuum concentration at a temperature of 40° C. to obtain a concentrated solution B with a solid content of...

Embodiment 2

[0031] Take 0.2 kg of perilla leaves and 1.8 kg of green tea, wash them and grind them. A small amount of deionized water was added to infiltrate for 3 hours, and then the mixture of perilla leaves and tea leaves was poured into a countercurrent extractor for extraction to obtain a crude filtrate. Use a precision filter membrane containing a polypropylene fiber membrane filter element for preliminary filtration to remove fine particles in the crude filtrate. Then filter with an ultrafiltration membrane with a molecular weight cut-off of 120,000 Daltons to remove macromolecular substances such as pectin, protein, and soluble starch, and obtain an ultrafiltration permeate. Then the ultrafiltration permeate was concentrated by reverse osmosis membrane, and the temperature was controlled at 40°C until a concentrated solution A with a solid content of 15% was obtained. Take half of the concentrated solution A and carry out low-temperature vacuum concentration at a temperature of 4...

Embodiment 3

[0033] Take 0.3 kg of perilla leaves and 1.7 kg of jasmine tea, wash and pulverize. Add a small amount of deionized water to soak for 2.5 hours. Use the same extraction, coarse filtration, and ultrafiltration as in Example 1 to obtain an ultrafiltration extract. Then the ultrafiltration extract was concentrated by a reverse osmosis membrane, and the temperature was controlled at 30°C until a concentrated solution A with a solid content of 20% was obtained. Take half of the concentrated solution A and carry out low-temperature vacuum concentration at a temperature of 43° C. to obtain a concentrated solution B with a solid content of 33%. After the concentrated solution B is mixed with the remaining concentrated solution A, ultra-high temperature instantaneous sterilization is carried out at 130° C., and the sterilization time is 4 seconds. Finally, freeze-drying is carried out, and the prepared perilla instant tea powder can be dissolved rapidly after adding water at 15° C., ...

Abstract

The invention relates to a preparation method for health-care tea powder, and particularly to a preparation method for purple perilla instant tea powder. The method successively comprises the following steps of washing purple perilla leaves and tea leaves clean, smashing the purple perilla leaves and the tea leaves, mixing the purple perilla leaves and the tea leaves according to a weight ratio of 1:4-9, adding the above mixture into deionized water to immerse for 2-3 hurs, pouring the immersed mixture in a countercurrent extraction machine for extraction, and thus a crude filtrate is obtained; performing a preliminary filtration on the crude filtrate with a precision filter membrane containing polypropylene fiber membrane filter element to remove fine particles in the crude filtrate, and thus a preliminary filtrate is obtained; performing ultrafiltration on the preliminary filtrate; concentrating a permeating solution of the ultrafiltration with a reverse osmosis membrane to reach the solid content of 5%-20%, and thus a concentrated solution A is obtained; taking half of the concentrated solution A to perform a vacuum concentration, so that a concentrated solution B with the solid content of 30%-35% is obtained; mixing the rest of the concentrated solution A with the concentrated solution B to obtain a concentrated solution C; sterilizing the concentrated solution C, and drying the sterilized concentrated solution C to obtain the tea powder. The tea powder obtained by the method is easy for extraction, has low pesticide residue, and is good in color, flavor and taste.

Description

technical field [0001] The invention relates to a preparation method of functional health food tea powder, in particular to a preparation method of perilla instant tea powder. Background technique [0002] Traditional instant tea extraction techniques include tank extraction, continuous countercurrent extraction, and multi-tank countercurrent extraction. The disadvantage of tank type extraction and continuous countercurrent extraction is that the tea leaves are easy to block the filter screen, making it difficult to discharge, and sometimes it is impossible to come out at all. The disadvantage of multi-tank countercurrent extraction is that the tea leaves are easy to float on the water surface, and some of them are drawn out without being fully extracted, resulting in a certain amount of waste. [0003] The manufacture method of instant tea powder is usually earlier with hot water extraction, and after reverse osmosis concentration or vacuum concentration, carries out spray...
