Abstract
The present invention discloses preparation process of instant green tea powder. Through low temperature slow freezing to form largest ice crystal destroying the cell tissue of fresh tea leaf, the present invention reaches the aim of raising leaching efficiency; and through enriching process, the present invention extracts the chlorophyll and effective components from fresh tea leaf. The present invention has simple operation and low cost, and the prepared instant green tea powder is emerald green, scent and high in tea polyphenol content.
Description
Technical field
The present invention relates to the technology for processing instant tea field, more particularly, relate to a kind of technology based on fresh tea leaf raw material extraction chlorophyll and active ingredient, the spray-dried method that is processed into instant green tea powder of the concentrate of extraction is applied to beverage tea or is used as other cakes and sweetmeats product additive.
Background technology
At present, the processing of instant green tea powder utilizes finished product green tea raw material mostly, and adopts hot water lixiviate, filtration, heat to concentrate and spray-dired technology.Water temperature 90-95 ℃ of carrying of hot dipping wherein, tea: the water ratio is about 1: 12; Heat concentrates and adopts about 45 ℃ vacuum to concentrate.The subject matter and the shortcoming of these methods are: the hot water lixiviate of the heated drying in the Tea Processing, high-temperature and hot for a long time concentrated destruction (as the decomposition and the oxidation of chlorophyll and Tea Polyphenols) of causing heat sensitivity composition in the green tea.Therefore, the instant green tea powder of this processes is difficult to keep the original color style of green tea raw material.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of method for preparing instant green tea powder is provided.
The present invention adopts following technical scheme to realize the present invention: a kind of method for preparing instant green tea powder may further comprise the steps: get bright leaf, carry out cleaning and sterilizing; At go out enzyme 10~18 seconds of 95 ℃~100 ℃ water temperature blanchings; Low temperature is slow under-2 ℃~-3 ℃ temperature froze 6~8 hours; Continuous freezing 10~12 hours forms the ice crystal broken leaf under-12 ℃~-15 ℃ temperature; Pulverize through colloid mill again after the coarse crushing of ice crystal broken leaf; Squeeze the juice, filter; Leachate adds the ice crystal broken leaf of coarse crushing again to be pulverized through colloid mill, squeezes the juice, and filters, and so circulates 2~4 times, is enriched to the concentrate that solid content reaches 10-12%; Concentrate adds among beta-schardinger dextrin-, maltodextrin, xanthans, konjac glucomannan, the CMC at least a to solid content 15-16%; Spray-drying prepares instant green tea powder.
The invention has the beneficial effects as follows:
1. the polyphenol content according to the instant green tea powder of method of the present invention preparation is higher than conventional green tea powder, this method produce the polyphenol content of green tea powder be higher than 36%, and the polyphenol content of conventional green tea powder has only about 30%.
2. emerald green according to the instant green tea powder color and luster of method preparation of the present invention, tealeaves delicate fragrance appears; And the green tea powder that conventional method is produced is light yellow, and tea perfume (or spice) is not obvious.
3. the present invention is simple to operate, is easy to grasp, and cost is low.
The specific embodiment
Further specify the present invention according to specific embodiment below, purpose of the present invention and effect will be more obvious.
We design a kind of technology of directly processing instant green tea powder from the bright leaf of tea, adopt the broken leach extraction method of cell tissue ice crystal to replace the method that traditional hot dipping is put forward, extract chlorophyll and active ingredient in the green tea, and remove hot enrichment process from by the circulation enrichment, the chemical composition that makes green tea concentrated liquid or green tea powder product keep raw material is largely formed, and makes it to have the original local flavor of green tea.
More particularly, fresh tea leaf goes out enzyme blanching 10~18 seconds, cooling back slow freezing 6~8 hours of-2 ℃~-3 ℃ temperature sections through 2ppm bleaching powder cleaning and sterilizing, 95 ℃~100 ℃ hot water, continuous freezing 10~12 hours under-12 ℃~-15 ℃ temperature forms the ice crystal broken leaf then; The ice crystal broken leaf is carried out coarse crushing by conventional pulverizer, pulverizes through colloid mill after the coarse crushing again, and the weight ratio of material water is 1: 4 during pulverizing; Squeeze the juice after the pulverizing, filter; Leachate adds the ice crystal broken leaf of coarse crushing again to be pulverized through colloid mill, squeezes the juice, and filters, and so circulates 2~4 times, is enriched to the concentrate that solid content reaches 10-12%; Concentrate adds among beta-schardinger dextrin-, maltodextrin, xanthans, konjac glucomannan, the CMC at least a to solid content 15-16%, further is processed into instant green tea powder by spray-drying then.
Embodiment 1
With the bright leaf of the tea of 4.5Kg through 2ppm bleaching powder cleaning and sterilizing, float the enzyme 18 seconds of going out 95 ℃ of having one's hair waved, put into low temperature refrigerator or freezer after the cooling-2 ℃ of temperature sections slowly freezing 8 hours,-12 ℃ of continuous down freezing 12 hours, taking out the back that slightly thaws rubs, pulverize (the water w/w ratio of just expecting is 1: 4) by colloid mill then, squeeze the juice after the pulverizing, filter; Leachate adds the ice crystal broken leaf of rubbing again to be pulverized through colloid mill, so circulates 2 times, is enriched to solid content and reaches 10% the about 4500ml of concentrate.Add in the leaching liquor among beta-schardinger dextrin-, maltodextrin, xanthans, konjac glucomannan, the CMC at least a to the inspissated juice solid content reach 15%, spray-drying again, the about 0.86Kg of instant green tea powder.
Embodiment 2
With the bright leaf of the tea of 4.5Kg through 2ppm bleaching powder cleaning and sterilizing, float the enzyme 10 seconds of going out 100 ℃ of having one's hair waved, put into low temperature refrigerator or freezer after the cooling-3 ℃ of temperature sections slowly freezing 6 hours,-15 ℃ of continuous freezing 10 hours, taking out the back that slightly thaws rubs, pulverize (the water w/w ratio of just expecting is 1: 4) by colloid mill then, squeeze the juice after the pulverizing, filter; Leachate adds the ice crystal broken leaf of rubbing again to be pulverized through colloid mill, so circulates 3 times, is enriched to solid content and reaches 12% the about 4500ml of concentrate.Add in the leaching liquor among beta-schardinger dextrin-, maltodextrin, xanthans, konjac glucomannan, the CMC at least a to the inspissated juice solid content reach 16%, spray-drying again, the about 0.90Kg of instant green tea powder.
