Embodiment 1

[0026] (a) Soaking: Soak the white lentils in warm water at 45°C for 6 hours.

[0027] (b) Grinding and refining: use a hammer mill or a bead mill to control the temperature at 38℃, firstly coarsely grind and then finely grind twice. The first coarse grind and grind will break the lentils into 6 petals and remove the skin fibers. ; The second fine grind and smash to control the solids particle size in the white lentil milk at 100-110μm. In the process, add 1:3 water with the white lentils to obtain the white lentil puree.

[0028] (c) Separating the fiber; the white lentil puree obtained is separated and washed with a pressure curved sieve, and washed with water with a volume ratio of 1:2 to the white lentil, pH value is 4.3, and the temperature is 45°C. Lentil fiber pulp and white lentil starch milk under the sieve, the free starch content in the white lentil fiber slurry is 3%, and the fiber fine residue content in the white lentil starch milk is 0.08%.

[0029] (d) Separating sta...

Embodiment 2

[0037] (a) Soaking: Soak the white lentils in 47.5°C warm water for 7 hours.

[0038] (b) Grinding and refining: Use a hammer mill or a bead mill to control the temperature at 39°C. Carry out coarse grinding and then fine grinding twice. The first grinding is to beat the lentils into 7 petals and remove the skin fibers; After the second pulverization, the solids particle size in the white lentil milk is controlled to be 105μm, and the white lentil water is added at the same time in the process to obtain the white lentil puree.

[0039] (c) Separating the fiber; the white lentil puree obtained is separated and washed with a pressure curved sieve, and washed with clean water with a volume ratio of 1:2 to the white lentil, the pH is 4.4, and the temperature is 47.5°C. Lentil fiber pulp and white lentil starch milk under the sieve, the free starch content in the white lentil fiber slurry is 4%, and the fiber fine residue content in the white lentil starch milk is 0.09%.

[0040] (d) Sep...

Embodiment 3

[0048] (a) Soaking: Soak the white lentils in warm water at 50°C for 8 hours.

[0049] (b) Grinding and refining: use a hammer mill or a bead mill to control the temperature at 40°C, first coarsely grind and then finely grind twice. The first pulverization will break the lentils into 7 petals and remove the skin fibers; After the second pulverization, the solid particle size in the white lentil milk is controlled to 105μm, and the white lentil water is added at the same time in the process to obtain the white lentil puree.

[0050] (c) Separate fiber; the white lentil puree obtained is separated and washed with a pressure curved sieve, and washed with water with a volume ratio of 1:2 to the white lentil, pH value is 4.5, temperature is 50°C, and the sieve is white. Lentil fiber pulp and white lentil starch milk under the sieve, the free starch content in the white lentil fiber slurry is 5%, and the fiber fine residue content in the white lentil starch milk is 0.1%.

Abstract

The invention discloses a preparation method of white hyacinth bean extract powder. The white hyacinth bean extract is composed of white hyacinth bean fiber powder, white hyacinth bean starch, and white hyacinth bean protein powder. The preparation method comprises the following steps: (a) soaking; (b) grinding and pulping; (c) separating the fibers; (d) separating the starch; (e) separating the protein; (f) dehydrating and drying. The method has the advantages of simple operation, safety, and no pollution, can produce white hyacinth bean fiber powder, white hyacinth bean starch, and white hyacinth bean protein powder at the same time, and has the characteristics of large yield, good stability, and high repeatability.

Description

Technical field [0001] The invention relates to a method for preparing white lentil extract powder, in particular to a method for preparing white lentil fiber powder, white lentil starch or white lentil protein powder. Background technique [0002] Lentils are mainly distributed throughout the tropical and subtropical warm regions, and are most cultivated in countries such as India and Indonesia. It is widely distributed in my country, and more cultivated in the south of the Yangtze River. It is an important vegetable variety and a plant resource for medicine and food in my country. White lentils are the mature white seeds of lentils. They have the advantages of invigorating the spleen, reducing dampness, diuresis and swelling, clearing the liver, improving eyesight, replenishing deficiency and stopping diarrhea. The pharmacological function of a greasy, damp-invigorating but not violent medicine for invigorating the spleen and resolving dampness is recorded in the "Conference M...
