Problems solved by technology

[0002] Wine is gradually accepted by more and more people, and its demand is also increasing day by day, which has created huge wealth for the wine industry. The treatment of wine wine skins is generally directly discarded or used as fuel, but such treatment is a great waste of resources and also pollutes the environment
[0003] Because grape skin contains a large amount of polyphenols and tannins, these substances have health functions such as anti-tumor, anti-arteriosclerosis and prevention of hypertension, so the utilization of grape skin in the current research is mostly concentrated on the use of grape skin. Extract polyphenols, tannins or other active ingredients, and then apply the extracted substances, such as ultrasonic solvent extraction, pulsed electric field assisted countercurrent extraction, one-step ball ...

Embodiment 1

[0024] This embodiment relates to a preparation method of grape skin superfine powder with coffee aroma.

Embodiment 11

[0026] The grape skin superfine powder with coffee aroma is prepared from the grape skin pomace produced in the wine brewing production process, comprising the following steps:

[0027] a1, the grape skin pomace is carried out the separation of grape skin and grape seed, obtains moist grape skin;

[0028] a2. Freeze the grape skins at -25°C for 20 hours, then freeze-dry the grape skins in a freeze dryer, quickly cool down to -18°C at 5°C / min, and dry for 12 hours, so that the water content of the grape skins is 5%. , to the extent that it is crushed when pinched, and the surface of the obtained dried grape skin is covered with small holes;

[0029] b. Coarsely pulverize the dried grape skins in a flour mill, sieve, and collect grape skin powders with a particle size less than 1500 μm;

[0030] c. Grinding and pulverizing the coarsely pulverized grape skin powder step by step in an ultracentrifugal grinder, with a grinding and pulverizing rate of 16000 rpm, performing primary ...

Abstract

The invention relates to a preparation method of grape skin superfine powder with a coffee aroma. The preparation method comprises the steps that wet grape skin is freeze-dried, coarsely smashed and then ground and smashed step by step to obtain the grape skin superfine powder with the coffee aroma. The obtained grape skin superfine powder can be used as a solid beverage to be directly and instantly drunk with hot water, and the beverage is ruddy in color and luster, has the bitter aroma of coffee and the aroma of grape fruits, is rich in nutrition, and has the healthcare functions of losing weight, reducing blood fat and cholesterol, protecting blood vessels and the like. In addition, the preparation method is simple and safe, and an efficient reutilization method is provided for grape skin waste residues generated in the wine brewing production process. Meanwhile, the invention relates to the solid grape skin beverage with the coffee aroma, and the healthy and delicious beverage is provided for people.

Description

technical field [0001] The invention relates to a preparation method of fruit skin superfine powder, in particular to a preparation method of grape skin superfine powder with coffee aroma. At the same time, the invention also relates to a grape skin solid beverage with coffee aroma. Background technique [0002] Wine is gradually accepted by more and more people, and its demand is also increasing day by day, which has created huge wealth for the wine industry. The treatment of wine wine skins is generally discarded directly or used as fuel, but such treatment greatly wastes resources and pollutes the environment. [0003] Because grape skin contains a large amount of polyphenols and tannins, these substances have health functions such as anti-tumor, anti-arteriosclerosis and prevention of hypertension, so the utilization of grape skin in the current research is mostly concentrated on the use of grape skin. Extract polyphenols, tannins or other active ingredients, and then a...
