Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of mouthfeel is good, the zinc selenium tea beverage that can retain green tea sweet-smelling and processing technology thereof.
To achieve these goals, the technical scheme that the present invention takes is: a kind of zinc selenium tea beverage, and described zinc selenium tea beverage is made up of following component:
Zinc selenium tea tea juice 30g, honey 0.2g and vitamin C 0.1g.
This zinc selenium tea beverage formula is simple, and not additive pigment, anticorrisive agent, sucrose, green natural, mouthfeel is good, can retain the sweet-smelling of green tea.
A processing technology for zinc selenium tea beverage, described processing technology comprises the following steps:
(1) cold extraction, carries out low-temperature extraction by zinc selenium tea at 20 DEG C;
(2) temperature extraction, temperature extraction during the zinc selenium tea after cold extraction is carried out at 60 DEG C;
(3) centrifugal filtration, adds honey and vitamin C, carries out centrifugal filtration in the zinc selenium tea tea juice of extraction;
(4) enzymolysis, carries out enzymolysis by the zinc selenium tea tea juice after centrifugal filtration in enzymatic vessel, and enzymolysis adopts pectase, temperature 45 C-55 DEG C, 5 hours time;
(5) ultrafiltration, by the zinc selenium tea tea juice fine filtering after enzymolysis;
(6) multi-effect vacuum concentrates, and the zinc selenium tea tea juice after fine filtering is carried out Multi-effect concentration at 60 DEG C-70 DEG C, and concentration time per ton is 2 hours;
(7) Physico-chemical tests, detects the zinc selenium tea tea juice after Multi-effect concentration;
(8) sterile filling, by the tea juice flash-sterilization after detection, temperature 110 DEG C, 10 seconds time, in closed conduct, in the filling indoor of ultrapurification air, every 8 hours start and stop disinfections, keep sterilized space, be more than or equal at the temperature of 86 DEG C filling, by the sterilization 15 minutes at 121 DEG C-125 DEG C of horizontal sterilization kettle after filling;
(9) refrigerate, warehouse-in refrigeration.
This production technology, when not adding pigment, anticorrisive agent and sucrose, achieves the production of zinc selenium tea beverage, and ensure that the mouthfeel of beverage, remains the sweet-smelling of green tea.

A kind of concrete prioritization scheme, the Testing index in described step (7) is as follows:
Pol is more than or equal to 3.5,
PH value 6.0,
Outward appearance is in clarification, bright, yellow,
Fragrance, has natural green tea spontaneous combustion tea perfume and simple and elegant honey fragrance,
Local flavor, sugariness is moderate, has the peculiar taste of zinc selenium tea,
Quality, mouthfeel is micro-puckery, the sense of fresh tea tea.
Owing to have employed technique scheme, the present invention has following characteristics:
This zinc selenium production of tea drinks simple and reliable process, obtained product is not containing pigment, anticorrisive agent and sucrose, and natural green, mouthfeel is good, adopts TRANSIENT HIGH TEMPERATURE sterilizing, remains the sweet-smelling of green tea.
Below in conjunction with detailed description of the invention, the present invention is further detailed.
