Instant coffee is convenient in storage of coffee powder and brewing of coffee, but has disadvantages of being less preferred and poorly flavorful. Disclosed is a method of preparing instant coffee containing an aroma extract. The method includes preparing coffee powder by roasting dried coffee beans in an agitator at 50-100 rpm at 200-250 DEG C, grinding the roasted coffee beans, extracting the ground coffee beans with purified water under reflux at a boiling point, and concentrating, freeze-drying and grinding the coffee extract; automatically spraying a liquid-phase aroma extract of 0.01-5 wt%, based on the total weight of coffee powder contained in the instant coffee, through a spray nozzle below 10 DEG C into the coffee powder of 5-15 wt%, based on the total weight of coffee powder contained in the instant coffee, with agitation; filtering the mixture with a sieve; and mixing the filtrate with the residual part of the total coffee powder.
Description
Technical field
Generally speaking, the present invention relates to a kind of instant coffee preparation method who contains aroma extract.The invention particularly relates to a kind of preparation method of instant coffee, this instant coffee contains aroma extract, and is more welcome and taste is better, and this preparation method is included in and continues the heating that refluxes under the boiling temperature, with the extraction coffee bean; Concentrated coffee extract under certain pressure; Cooling, drying and ground coffee concentrate; In coffee powder, mix liquid spice.
Background technology
The coffee crop is to belong to rubiaceous evergreen shrubs, and initial growth is in annual rainfall 1, and 500-2 is under the tropical climate condition of 000mm.Quality coffee originates from height above sea level 1,000-3,000 meter.With commerce is that the coffee crop that purpose is planted has three kinds, be respectively arabica coffees (ARABICA), Robusta (ROBUSTA) and Liberia's coffee (LIBERIA), wherein arabica coffees and Robusta are occupied an leading position in coffee market, the world.
Coffee is the preferred drink in the global range.Especially now make coffee, it has the fragrance of distinctive taste and coffee bean, and reason is that it is by the baking and the coffee bean of mill-drying, and now make with water hot extraction's coffee powder.
On the contrary, instant coffee is powdery or particle-shaped coffee, and its typical production is as follows, filter baking and grind after coffee bean, the moisture in the evaporated filtrate, and coffee extract carried out cool drying or spray-drying.Like this, instant coffee just can be drunk easily by being dissolved in hot water.
About 1890, the instant coffee import is to Korea S, and its consumption figure just improves greatly afterwards.Now, instant coffee is Korea S's one of the most ace-high food.
On the other hand, recently, improve now make coffee and function, quality and the taste of instant coffee aspect done some researchs.For instance, in now making coffee, add the liquid spice material, as fibert; In instant coffee, add powdered flavour or vanilla etc.
Can prepare the functional form instant coffee by the description in korean patent application 99-0018589 number.Wherein, a kind of method for preparing vanilla coffee is disclosed, comprise animal material (as pilose antler, deer horn), Insecta IT1 dipteron raw material (as silkworm, honey, hornet's nest etc.), Insecta Chcilopoda or homopteran raw material (as centipede, periostracum cicada etc.), and/or mushroom (as assorted mushroom of glossy ganoderma, Colriolus and assorted Plutarch mushroom etc.).
In addition, also mentioned a kind of method for preparing vanilla coffee, having comprised for korean patent application 2000-030404 number: at 200-250 ℃ of roasting coffee beans, to produce coffee powder; Grind the coffee bean after toasting; With the pure water heating that under boiling point, refluxes, the coffee bean after grinding with extraction; Concentrate, cool drying and ground coffee extract; Rein in grass, arrowroot, ginkgo leaf, pilose antler, Korea S's angelica root, cornus fruit, glossy ganoderma and pumpkin etc. by predetermined quantity mixing witloof, rhizoma atractylodis, mouse, aroma extract with the preparation powdery, grind the vanilla mixture then, with the pure water heating that under boiling point, refluxes, the vanilla mixture after grinding with extraction; Concentrate, cool drying and grind the vanilla mixture; Coffee powder and the weight ratio that with weight ratio is 90-99% is that the aroma extract of 1-10% is mixed.Yet because the vanilla material volatilizees under the fricative heat effect when cool drying or in the grinding steps, the method can't keep natural aromatic and the taste of vanilla.
As mentioned above, make by water hot extraction's coffee bean owing to now make coffee, liquid spice can disperse wherein equably, and can keep the longer time.On the contrary, when in instant coffee, adding liquid spice, the spices skewness, and coffee powder can lump.For this reason, a lot of functional mass of using are Powdered.
Therefore, quality and taste aspect, now making coffee is better than instant coffee.Yet the preparation process of now making coffee is also inconvenient, because need the storage coffee bean, and also will be through steps such as overbaking, grinding and extractions.Instant coffee is more convenient aspect the storage of coffee powder and coffee brew, but its shortcoming is not to be that first-selection and taste are relatively poor.
Summary of the invention
By to can thoroughly discovering with the instant coffee of now made coffee comparable improvement quality and taste: when utilizing nozzle to spray into the liquid spice extract in instant coffee, its quality and taste improve greatly.This discovery causes generation of the present invention.
