Description

Coffee goat milk and preparation method thereof
Technical Field
The invention relates to coffee goat milk and a preparation method thereof, and belongs to the technical field of coffee and milk powder processing.
Background
Coffee (coffee) is a beverage made of roasted and ground coffee beans, is one of three major beverages in the world, contains caffeine, can promote blood circulation of a human body, accelerate metabolism, relieve muscle fatigue and promote digestion, and in order to enrich nutrient content, people often prepare coffee and milk to prepare a new beverage, for example, latte is a classic coffee made of espresso and milk, cappuccino is a mixture of espresso and steam foamed milk, and the like. However, these products are prepared by combining coffee with cow milk, and the combination of coffee and other animal milks is rarely used.
The goat milk is regarded as a fine product in the dairy product by the advantages of rich nutrition, easy absorption and the like, is called as 'king in milk', is a dairy product which is recognized in the world and is closest to human milk, the volume of fat particles of the goat milk is one third of that of the milk, the goat milk is more beneficial to human body absorption, the goat milk cannot cause fatness after being drunk for a long time, the burden of a digestive system is reduced, the contents of protein, fat and mineral substances in the goat milk dry matter are higher than those of the human milk and the cow milk, and the content of lactose is lower than those of the human milk and the cow milk; for the old, the goat milk has good nourishing effect due to warm nature, and has the effects of tranquilizing and allaying excitement half an hour before sleep; the goat milk is more suitable for people with anaphylaxis, gastrointestinal diseases, bronchitis or asthenia, and infants, but contains caproic acid (C)10H20O2) Caprylic acid (CH)3(CH2)6COOH), and decanoic acid (C)10H20O2) The sheep milk contains chemical components, so that most of the sheep milk has unacceptable fishy smell, and the application of the sheep milk is greatly limited.
Therefore, the provision of a new goat milk product is of great significance for opening the goat milk application market.
Disclosure of Invention
In order to solve the technical problems, a novel coffee goat milk and a preparation method thereof are provided aiming at the problem that the goat milk is not accepted by the public at present.
In order to achieve the purpose, the invention provides the following scheme:
the invention provides a preparation method of coffee goat milk, which takes goat milk powder and coffee powder as raw materials, wherein the mass ratio of the goat milk powder to the coffee powder is (50-99.9): 0.1-50.
Further, the preparation method of the coffee goat milk comprises the following steps:
weighing goat milk powder and coffee powder according to the mass ratio of (50-99.9) to (0.1-50), and dry-mixing to obtain the coffee goat milk.
Further, the preparation process is carried out under aseptic conditions.
Further, the mixing time is not less than 10 min.
Further, the sources of the goat milk powder and the coffee powder are not limited.
The invention also provides the coffee goat milk prepared by the preparation method.
The invention discloses the following technical effects:
although goat milk has many advantages, the goat milk has too much fishy and mutton smell, and although the fishy and mutton smell can be covered to a certain extent by adding coffee, caffeine in the coffee can often hinder calcium absorption of a human body, so that a drink prepared by mixing dairy products and coffee can damage the liver if being drunk for a long time, and the mixture can generate emulsion which is not stable and difficult to digest. In order to reduce the adverse reaction, the French people adopt a special drinking method, namely coffee and milk are respectively brewed, then the coffee is poured into the milk, but the milk is not poured into the coffee, so that the milk deterioration and the caused uncomfortable reaction are avoided. However, this brewing method is cumbersome and not suitable for instant drinks. The instant coffee goat milk beverage directly takes goat milk powder and coffee powder as raw materials, the proportion of the goat milk powder to the coffee powder is strictly limited, the smell of the goat milk can be successfully covered by using the aroma components contained in the quantitative coffee powder, the prepared coffee goat milk can be accepted by the public, meanwhile, the quantitative coffee powder can not cause discomfort of the liver, can not bring harm to the liver even if being drunk for a long time, and has proper proportion, thereby having important significance for the popularization of the instant coffee goat milk beverage.
The goat milk powder used in the coffee goat milk has rich contents of nutrient substances such as protein, fat and the like, can reduce the problem of difficult calcium absorption caused by caffeine in the coffee powder, is suitable for any people by taking the goat milk powder as a main component, is particularly suitable for people suffering from malnutrition, consumptive disease weakness, thirst quenching, stomach regurgitation, pulmonary tuberculosis cough and chronic nephritis to eat, cannot cause certain damage to human liver organs after being mixed with milk and coffee for a long time and can be drunk for a long time.
The coffee goat milk prepared by the invention can be drunk after being brewed, is convenient to eat, has fine texture, does not cause loss of nutrient components of the coffee goat milk, has simple preparation process, is suitable for large-scale production, and widens the application range of the goat milk.

Example 3
Weighing 99.9g of goat milk powder and 0.1g of coffee powder, and mixing and stirring in a dry mixing machine for 10min to obtain the coffee goat milk.
Example 4
Weighing 50g of goat milk powder and 50g of coffee powder, and mixing and stirring in a dry mixing machine for 10min to obtain the coffee goat milk.
Example 5
Preparing freshly ground coffee powder: washing raw coffee beans with water, removing foreign matters such as metal, stone particles, dust, broken beans, and mildewed beans, baking at 202 deg.C for 15min to make the coffee bean content undergo complex physical and chemical reaction to form specific coffee aroma, grinding to diameter of about 0.5mm to obtain coffee powder, and storing at 25 deg.C for use.
Preparing the goat milk powder: pretreating qualified raw goat milk, sterilizing at 82 deg.C for 15s, concentrating to 1/4 of original volume, controlling the milk temperature at 48 deg.C, spraying into a drying tower in a high-pressure pump, spraying under high pressure at 15MPa, controlling the material temperature at 55 deg.C, and drying to obtain goat milk powder. The goat milk powder produced by using the pure raw goat milk basically keeps the original nutritional ingredients in the goat milk, after the raw goat milk is processed into milk powder, the water content is reduced from the original 88% to 2% -5%, the contents of nutrients such as protein, inorganic salt, fat and the like are concentrated, the protein is not less than 24%, and the fat is not less than 26%. About 8-9 kg raw goat milk is needed to produce 1 kg of full-fat goat milk powder.
Mixing: and weighing 80g of the prepared goat milk powder and 20g of coffee powder, and mixing and stirring in a dry mixing machine for 10min to obtain the coffee goat milk.
Comparative example 1
The same as example 1 except that 45g of powdered goat milk and 55g of powdered coffee were weighed.
