Abstract

The invention relates to a method for processing and preparing a green milk powder, comprising the following steps: a. pretreatment: cutting a plant from the position 2-5 cm away from the ground when the tender plant grows to 25-45 cm, washing by tap water to remove soil and impurities on the surface thereof, washing by fresh water after ozone bacteria-killing at room temperature, washing by deionized water, and crushing the tender plant; b. filtering: juicing the obtained crushed tender plant, filtering and taking juice; c. mixing: evenly mixing the juice with raw milk proportionally to prepare into homogenized liquid; d. concentrating: evaporating and concentrating the obtained homogenized liquid by an evaporator to prepare concentrated solution; and e. drying: drying the concentrated solution to prepare into green milk powder. The invention has simple process flow and the processing procedure does not damage thermo-sensitive substances such as vitamin C, chlorophyll, SOD and the like in tender plant.

Claims

1. A method of preparing a green milk powder, comprising the following steps:

a. pretreatment, comprising

cutting a plant sprout at 2˜

5cm above the ground when the plant sprout grows up to 25˜

45 cm high,

washing soil and impurity away from the plant sprout surface,

washing the plant sprout by ozonized sterilization running water, and then washing the plant sprout by deionized running water at room temperature, and

crushing the plant sprout;

b. filtration, comprising juicing, filtering, and extracting juice from the crushed plant sprout;

c. blend, comprising mixing the juice from step (b) and a whole milk in pre-determined proportion until the mixture becomes a homogeneous juice;

d. concentration, comprising concentrating the homogeneous juice by evaporation using an evaporator until it becomes a concentrated liquid; and

e. drying the concentrated liquid and making it into a milk powder;

wherein the plant sprout is selected from the group consisting of barley sprout, wheat sprout, highland barley sprout, buckwheat sprout, black barley sprout, oat sprout, wild oat sprout, and combinations thereof; and

wherein the juice in step (c) is 40% by weight of the whole milk.

2. The method according to claim 1, wherein the volume of ozonized water in step (a) is 1˜

3% of the total volume of water.

3. The method according to claim 1, wherein the blending in step (c) is carried out in time condition in step (c) is 10˜

40 minutes at room temperature.

4. The method according to claim 1, wherein in step (d), the concentrating is carried out in the condition as follows:

the temperature is 30˜

40°

C., the vacuum degree being 0.08˜

60 minutes, and the weight percentage of solid content in concentrated liquid is 10%˜

30%.

5. The method according to claim 1, wherein the drying process in step (e) uses spray drying.

6. The method according to claim 1, wherein the drying process in step (e) uses vacuum freezing drying method or draper-type vacuum method.

7. A method of preparing a green milk powder comprising following steps:

a. pretreatment, comprising

cutting a plant sprout at 2˜

5 cm above the ground when the plant sprout grows up to 25˜

45 cm high,

washing soil and impurity away from plant surface,

washing the plant sprout first with ozonized sterilization running water, and washing the plant sprout by deionized running water at room temperature, and

crushing the plant sprout;

b. filtration, comprising juicing, filtering, and extracting juice from the crushed plant sprout;

c. drying the juice from step (b) and making the concentrated juice into a natural plant powder;

d. blending the natural plant powder and a whole milk powder or other dairy powder and making the blend into green milk powder, wherein the natural plant powder is 40% by weight of the weight of whole milk powder or other dairy powder;

wherein the plant sprout is selected from the group consisting of barley sprout, wheat sprout, highland barley sprout, buckwheat sprout, black barley sprout, oat sprout, wild oat sprout, and combinations thereof.

8. The method according to claim 7, wherein the drying process in step (c) uses spray drying.
