Problems solved by technology

The general extraction method is to directly dissolve and extract green coffee beans with a solvent, and then directly dry them. The product of this method is not high in purity and contains more impurities. It needs to be separated many times before it can be reused, resulting in green coffee bean extracts The cycle of utilization and processing becomes longer, and the difficulty of processing increases

Embodiment 1

[0043] The embodiment provides a kind of green coffee bean powder, which is prepared through the following steps.

[0044] Step 1. Weigh 10 grams of green coffee beans, soak the green coffee beans in 90 ml of water to form a soaking solution, process the soaking solution for 30 minutes with a frequency of 40KHz ultrasonic waves, and obtain an extract after filtering.

[0045] Step 2, filtering the extract with a ceramic membrane with a pore size of 0.1 μm to obtain a filtrate.

[0046] Step 3, using the reverse osmosis membrane to concentrate the filtrate to a solid content of 30% (by weight) to obtain a concentrated solution. The working pressure of the reverse osmosis membrane is 1.0MPa, and the working temperature is 30°C.

[0047] Step 4, spray-drying the concentrate to a moisture content of 5% (weight), to obtain green coffee bean powder.

Embodiment 2

[0049] The embodiment provides a kind of green coffee bean powder, which is prepared through the following steps.

[0050] Step 1. Weighing 11 grams of green coffee beans, soaking the green coffee beans in 100 ml of water to form a soaking solution, treating the soaking solution with ultrasonic waves at a frequency of 25KHz for 42 minutes, and filtering to obtain an extract.

[0051] Step 2, filtering the extract with a ceramic membrane with a pore size of 0.1 μm to obtain a filtrate.

[0052] Step 3, using the reverse osmosis membrane to concentrate the filtrate to a solid content of 36% (weight), to obtain a concentrated solution. The working pressure of the reverse osmosis membrane is 1.1MPa, and the working temperature is 32°C.

[0053] Step 4, spray-drying the concentrated solution to a water content of 3% (weight), to obtain green coffee bean powder.

Embodiment 3

[0055] The embodiment provides a kind of green coffee bean powder, which is prepared through the following steps.

[0056] Step 1. Weighing 12 grams of green coffee beans, soaking the green coffee beans in 106 ml of water to form a soaking solution, treating the soaking solution with ultrasonic waves at a frequency of 40KHz for 53 minutes, and filtering to obtain an extract.

[0057] Step 2. Filter the extract with a ceramic membrane with a pore size of 0.16 μm to obtain a filtrate.

[0058] Step 3, using the reverse osmosis membrane to concentrate the filtrate to a solid content of 40% (by weight) to obtain a concentrated solution. The working pressure of the reverse osmosis membrane is 1.4MPa, and the working temperature is 40°C.

[0059] Step 4, spray-drying the concentrate to a moisture content of 4.7% (weight), to obtain green coffee bean powder. The homogeneous pressure of spray drying is 14.8MPa, the inlet air temperature of spray drying is 181°C, and the outlet air t...

Abstract

The invention provides green coffee bean powder and a making method thereof, and belongs to the field of making of foods. The making method comprises the following steps of A.1) performing ultrasonic wave leaching on green coffee beans for 10-20 minutes with water so as to obtain an extracting solution, wherein the ultrasonic wave frequency comprises 20KHz or 40KHz; A.2) filtering the extracting solution with a ceramic membrane of which the bore diameter is 0.05-0.22 [mu]m so as to obtain filtrate; A.3) concentrating the filtrate until the solid content is 30wt% or above with a reverse osmosis membrane so as to obtain a concentrated solution; and A.4) performing spray drying on the concentrated solution until the water ratio is 5wt% or below so as to obtain the green coffee bean powder. The green coffee bean powder made by the making method is good in water solubility, sufficiently reserves chlorogenic acid and caffeine in green coffee beans, and can reduce the working procedures of subsequent reprocessing, and utilization of the green coffee bean powder, so that the reusing difficulty of the green coffee bean powder is reduced, and the processing time is shortened.

Description

technical field [0001] The invention relates to the field of food production, in particular to green coffee bean powder and a production method thereof. Background technique [0002] Green coffee beans are the seeds of evergreen shrubs or small trees of Rubiaceae, which contain caffeine, tannin, fat, protein, sugar, minerals, chlorogenic acid and other ingredients. At present, green coffee beans are generally processed in order to extract components with medicinal value therein. The general extraction method is to directly dissolve and extract the green coffee beans with a solvent, and then directly dry them. The product of this method is not high in purity and contains more impurities. It needs to be separated many times before it can be reused, resulting in green coffee bean extracts The cycle of utilization and processing becomes longer and the processing difficulty increases. Contents of the invention [0003] The first object of the present invention is to provide a...
