Description
Technical field
The present invention relates to field of food.It is more particularly related to a kind of coffee infusion and preparation method thereof.
Background technique
Coffee converted products in China's is mainly stir-fried and grinded coffee and instant coffee at present, and stir-fried and grinded coffee can preferably reflect coffee
The original flavor of coffee, but need to boil or rush filter on special pot tool, drinks inconvenient, and instant coffee drinks convenience, but shows
The manufacture craft of some instant coffees sacrifices the fragrance of coffee to a certain extent, and the manufacture craft of existing instant coffee is main
Including following process: green coffee bakes, the ripe beans grinding of coffee, high temperature and pressure extracts, high temperature is dried into powder.It is dried in high temperature
The flavor of coffee itself, tartaric acid, tannin and flowers and fruits perfume (or spice) etc., in addition, the coffee of high temperature drying can be lost in the process by doing into powder
Powder needs high temperature that could dissolve in 80 DEG C or more of water, and there are also a little to be charred taste.
Summary of the invention
It is an object of the invention to solve at least the above problems, and provide the advantages of at least will be described later.
Coffee stoste taste can utmostly be retained it is a still further object of the present invention to provide a kind of, while only needing warm water
Or the coffee infusion that cold water can brew.
In order to realize these purposes and other advantages according to the present invention, a kind of coffee infusion is provided, including following heavy
Measure the raw material of part: 50~75 parts of freeze-drying ground coffees, 15~20 parts of malic acid powder, 20~30 parts of saleratus powers；
Wherein, it is described freeze-drying ground coffee the preparation method comprises the following steps: by coffee bean bake, grinding after plus water extraction, then filter
Coffee stoste is obtained, ingredient is added into coffee stoste and stirs evenly, then carries out vacuum freeze drying and obtains freeze-drying ground coffee.
Preferably, coffee bean used in the freeze-drying ground coffee is mainly Arabica and spreads out this two kinds；
The preparation method of the freeze-drying ground coffee specifically: above-mentioned coffee bean is mixed be placed on 150 DEG C bake and bank up with earth 10~
12min, then temperature is risen into 175 DEG C of 8~10min of baking, continue to rise to temperature into 205 DEG C of 10~12min of baking, it then will be warm
Degree rises to 220 DEG C of bakings 5min, and by the coffee bean baked cooling, grind into powder, powder size is in 35~80 mesh, then by powder
End, which is dissolved in 85~95 DEG C of water, stirs, extracts 5~10min, then filters to obtain coffee stoste with filter paper, is added into coffee stoste
Ingredient stirs evenly, then is placed in vacuum freeze drier and carries out vacuum freeze drying acquisition freeze-drying ground coffee.
Preferably, the ingredient includes sucrose, fructose, xylo-oligosaccharide wherein at least one.
Preferably, the coffee bean is stood overnight after baking, then is ground.
Preferably, after by the coffee bean grinding baked at powder, then it is aided with simultaneously to powder Air washer and stirs
It mixes.
Preferably, with gas pressurized is carried out in filter paper filter process, to improve the rate of filtration.
Preferably, the coffee infusion is pulvis or tablet.
Preferably, further include the raw material of following parts by weight: 10~12 parts of probiotic powders, 18~22 portions of skimmed milk powers, 7~
13 parts of wax-apple extracting solutions, 9~14 parts of cod-liver oil, 15~18 parts of carragheens, 3~7 portions of maltodextrins, 5~8 parts of calcium gluconates,
21~24 parts of vegetable fat powders.
Preferably, the wax-apple extracting solution the preparation method comprises the following steps: by wax-apple fruit chopping after be added wax-apple fruit weight 5
Deionized water again is placed in boiling under the pressure of 0.6MPa and boils 15min, and filter to get filtrate a, and filter residue is pounded pureed and adds filter residue
5 times of weight of cellulose hydrolyzation liquid hydrolyzes 4h, takes heating water bath and magnetic agitation to assist in hydrolytic process, heating water bath temperature
Degree is 37 DEG C, and the revolving speed of magnetic agitation is 110r/min, and filter to get filtrate b again, and filtrate b is boiled to being cooled to room after 85 DEG C
Temperature, then merge with filtrate a, obtain wax-apple extracting solution.
The present invention also provides the preparation methods of above-mentioned coffee infusion, comprising the following steps:
Step 1: the freeze-drying ground coffee of above-mentioned parts by weight, malic acid powder, probiotic powder and skimmed milk power are carried out dry-mixed obtain
To mixed powder；
Step 2: the wax-apple extracting solution, cod-liver oil and carragheen of above-mentioned parts by weight are mixed, 500~750 weight are added
Part deionized water, stirring is warming up to 50 DEG C simultaneously, is cooled to 35 DEG C after keeping the temperature 20min, and then 30~40min of reduction vaporization is dense
Contracting forms paste, and it is 5000~7000pa that pressure used, which is evaporated under reduced pressure, and temperature is 45 DEG C；
It stirs evenly, adds Step 3: the mixed powder that step 1 obtains is added in the paste that step 2 obtains
Above-mentioned parts by weight calcium gluconate continues to stir evenly, and the paste for being mixed with calcium gluconate is then spread evenly across material disc
Surface, coating thickness are 40~60um, and material disc is placed in vacuum freeze drier and carries out vacuum freeze drying acquisition sheet stock,
Sheet stock is ground into the particle that partial size is less than 40um again；
Step 4: the dry-mixed system of saleratus power, maltodextrin, vegetable fat powder of the particle that step 3 is obtained and above-mentioned parts by weight
At pulvis.
The present invention is include at least the following beneficial effects:
1, it baked by coffee bean, grinding, extract and filter the differently flavoured coffee stoste of acquisition, then will with freeze-drier
The slave liquid of coffee stoste is converted into solid-state, and locks the flavor of coffee stoste, then adds malic acid powder reduction extraction, filtered
The tartaric acid ingredient lost in journey, addition saleratus power quickening coffee brew solution rate.Coffee powder after freeze-drying or it is canned,
Or punching press is in blocks, consumer directly uses normal-temperature water or brewed in hot water powder or tabletting, it can quickly judges to different sources, no
With the coffee of flavor.
2, since the stimulating effect of coffee is preferable, coffee for drinking between most people like at work, however contain in coffee
A large amount of vegetable proteins, the plant for being sat for the people that office causes amount of exercise deficiency functions of intestines and stomach weaker for a long time, in coffee
Albumen can bring larger burden to stomach, can assist gastrointestinal disturbances by adding probiotic powder in the feed, it is negative to mitigate stomach
Load, while the wax-apple extracting solution added can be matched with the tanning matter in coffee, so that coffee goes back pleasant impression after the mellow sense of taste
Sweetness, reducing after existing coffee is drunk still has thirsty feeling, in addition also without addition cod-liver oil in existing coffee, mainly
It is that cod-liver oil is added under the action of profitable probliotics powder, not only will not because two kinds of drinks contain more protein component
The effect that cod-liver oil clears liver and improve vision can also be played completely by increasing stomach burden.
3, high temperature protein denaturation is avoided using 50 DEG C of warm water in preparation process, is discharged by the method that concentration is evaporated under reduced pressure
Moisture, it is possible to reduce the oxygenolysis of benefit materials in raw material, it is most important that the particle as made from the method for freeze-drying can
The activity of probiotics is kept, and the coffee making procedure of existing addition probiotics often uses high temperature spray-drying, can make so a large amount of
Probiotics inactivation, the probiotics coffee powder preparation method as disclosed in the patent of application number 201711311321.3.
Further advantage, target and feature of the invention will be partially reflected by the following instructions, and part will also be by this
The research and practice of invention and be understood by the person skilled in the art.
