A kind of preparation method of the ground coffee based on roasting
Technical field
The invention belongs to technical field of food beverage, being specifically related to a kind of preparation method of the ground coffee based on roasting.
Background technology
Coffee tree is the evergreen dungarunga of genus rubia section, the daily coffee drunk coordinates various different boiling appliance to make with coffee bean, and coffee bean just refers to the kernel inside coffee tree fruit, then cure by suitable method and form, it is bitter taste that product are tasted.
Coffee and tealeaves, cocoa be called the large beverage plant in the world three, Yunnan arabiancoffee, Rubiaceae, Coffea, originates in Ethiopia, plants the Dry-hot Valley Area in height above sea level about 1100 meters, so tart flavour is moderate, aromatic flavour and alcohol and.
Along with the fast development of China's economic society, rhythm of life is also being accelerated year by year, is operated in the white collar clan in high buildings and large mansions, is trapped in the work above a slight position, computer being carried out to high strength 8-10 hour every day.Such working method adds very large operating pressure to white collars, and health is very easily tired, immunity degradation.Most white collar coffee of selecting to have a drink when feeling fatigue is refreshed oneself, but coffee is pained, and the active ingredient in the coffee prepared in existing preparation method can not well be extracted, and causes the waste of nutritional labeling.
Summary of the invention
The object of this invention is to provide a kind of preparation method of the ground coffee based on roasting, the ground coffee fragrance that this preparation method prepares, mouthfeel are good, be with sweet in aftertaste hardship, aromatic flavour is stayed for a long time in space and mouth, and has and reduce cholesterol, reduce fat, improve heart body, treatment antimigraine effect.
The technical solution adopted in the present invention is, a kind of preparation method of the ground coffee based on roasting, comprises the following steps:
Step 1, brewed coffee beans: coffee bean is carried out machine and selects classification, cleaning, dries, removing impurity;
Step 2, to roast: the coffee bean modulated roasts under xeothermic state;
Step 3, cooling: cooled fast by the coffee bean roasted, adopt cold air air blast cooling or cooling process, prepare coffee bean;
Step 4, coffee bean grinding is become powder, prepare ground coffee.
In technique scheme, the condition of roasting is: temperature is more than 150 DEG C, and roast times is 8min ~ 12min.
The invention has the beneficial effects as follows: the present invention is the breakthrough that granule coffee roasts (curing) preparation method, is on the basis keeping the original structure of matter of coffee, reduces while other adds material and increases the new function of coffee solid beverage.Stoving temperature is controlled to roast (curing) fresh coffee beans in suitable scope, while not destroying the original structure of matter of coffee bean, the content of material in coffee structure can also be improved, improve its performance, add coffee substance content, breach conventional fabrication method.Roast the arabiancoffee beans after (curing), being made into ground coffee, to drink its mouthfeel good, the thin Tired of tart flavour, weak, and bitter taste is soft, and fragrance is stronger, and tart flavour is moderate.During thin product, band acid in hardship, aftertaste is fragrant rear sweet larynx first.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is described in detail.
The invention provides a kind of preparation method of the ground coffee based on roasting, comprising the following steps:
Step 1, brewed coffee beans: coffee bean is carried out machine and selects classification, cleaning, dries, removing impurity;
Step 2, to roast: the coffee bean modulated processes under xeothermic state, makes the structure of coffee bean and composition that great chemistry and physical change occur, and causes coffee bean dimmed and gives out the distinctive fragrance of roasted coffee.When just starting, roast temperature and should be raised to more than 150 DEG C, by a series of, plum rad (Maillard) reaction and Strecker decompose, and the protein and sugar in coffee bean reacts and generates the material of savory and color.Several main flavor materials in coffee are formed at this moment.The color of coffee bean is with to roast temperature relevant, and the higher color relation of temperature is darker.After roasting 8min ~ 12min, in coffee bean, moisture evaporates completely, the Mass lost 20% of coffee bean, but volume increases by 60%;
Step 3, cooling: cooled fast by the coffee bean roasted, adopt cold air air blast cooling or cooling process;
Step 4, coffee bean grinding is become powder, prepare ground coffee.
The present invention controls temperature to cure in proper range, to ensure the content of material in coffee bean; Decrease the interpolation (as: salt, wet goods need be added when tradition is cured) of other material.Mainly making the element in coffee bean be increased to more than 1200 kinds by curing, reducing other and adding material.With the coffee bean that this method is cured, look is that strong tea colour band is black, and its fragrance is stronger, and bitter taste comparatively tart flavour is strong, and bitter taste is soft, and tart flavour is moderate, simultaneously because its fat infiltrates into surface, with unique perfume.Be that the uniqueness of Baoshan arabiancoffee cures technology and gimmick, also embody the baking method of its uniqueness.
When drinking, the method liked with oneself is boiled (brewing), and fragrance, mouthfeel are good, is with sweet in aftertaste hardship, and aromatic flavour is stayed for a long time in space and mouth, and has and reduce cholesterol, reduce fat, improve heart body, treatment antimigraine effect.
