Embodiment 1

[0013] Remove the unqualified asparagus processing waste, and wash the silt on the surface with clean water for later use. Adjust the power of the microwave oven to 560W, and process the cleaned asparagus processing scraps in the microwave oven for 60 seconds until the POD in the asparagus is passivated. The asparagus processing waste after microwave treatment is beaten into a slurry by a beater, and hydrochloric acid with a concentration of 1mol / L is added to the slurry asparagus to adjust the pH value of the slurry asparagus to 5.0 to obtain asparagus slurry; then add to the asparagus slurry The cellulose complex enzyme with a mass ratio of 0.2% (calculated as the adjusted asparagus pulp) is used for enzymolysis at 60° C. for 1.5 h. Place the enzymatically hydrolyzed asparagus pulp in the cold trap of a vacuum freeze-drying device, freeze it at -40°C for 5 hours, and then vacuum freeze-dry it for 11 hours under the condition of a vacuum chamber pressure < 20Pa, until the wat...

Embodiment 2

[0015] Remove the unqualified asparagus processing waste, and wash the silt on the surface with clean water for later use. Adjust the power of the microwave oven to 560W, and process the cleaned asparagus scraps in the microwave oven for 70 seconds until the POD in the asparagus is passivated. Use a beater to beat the asparagus processing waste after microwave treatment into a slurry, then add a citric acid solution with a concentration of 1mol / L to adjust the pH value of the slurry asparagus to 5.5, and obtain asparagus pulp; then add its mass ratio to the asparagus pulp 0.15% (calculated as the adjusted asparagus pulp) cellulose complex enzyme, enzymatically hydrolyze at 60°C for 2 hours. Place the enzymatically hydrolyzed asparagus pulp in the cold trap of a vacuum freeze-drying device, freeze at -45°C for 4.5 hours, and then vacuum freeze-dry for 10 hours under the condition of a vacuum chamber pressure <20Pa, until the water content of the asparagus pulp reaches at 6%. ...

Embodiment 3

[0017] Remove the unqualified asparagus processing waste, and wash the silt on the surface with clean water for later use. Adjust the power of the microwave oven to 560W, and process the cleaned asparagus processing scraps in the microwave oven for 80 seconds until the POD in the asparagus is passivated. Use a beater to beat the asparagus processing waste after microwave treatment into a slurry, add 1mol / L acetic acid to the slurry asparagus to adjust the pH value of the asparagus slurry to 6.0, and obtain the asparagus slurry; then add its mass ratio of 0.1 to the asparagus slurry % (calculated as asparagus pulp after adjustment) of the cellulose complex enzyme, enzymolysis at 56 ° C for 1 h. Place the enzymatically hydrolyzed asparagus pulp in the cold trap of a vacuum freeze-drying device, freeze it at -50°C for 4 hours, and then vacuum freeze-dry it for 10.5 hours under the condition of a vacuum chamber pressure <20Pa until the water content reaches 4 %. After the aspara...

Abstract

The invention relates to a processing method of asparagus powder. Leftovers left after asparagus processing serve as raw materials to process the asparagus powder. According to the method, functional component damage can be reduced to the maximum degree, crude fibers are reduced, the content of soluble dietary fibers is increased, and then the problems of resource waste and environment pollution in the asparagus processing process are solved. The leftovers left after asparagus processing can be fully and effectively utilized, the asparagus resource utilization rate and the added value of asparagus are increased, and environment pollution is reduced. Compared with an existing processing method, technologies such as microwave processing, enzymolysis treatment and vacuum freeze-drying are adopted in the method, the produced asparagus powder is low in functional component loss, low in content of the crude fibers and high in content of the soluble dietary fibers, and therefore the eating quality and functional characteristics of the asparagus powder are remarkably improved.

Description

(1) Technical field [0001] The invention relates to a processing method of asparagus powder, which belongs to the field of food processing. (2) Background technology [0002] Asparagus officinalis is a plant of the Liliaceae family, also known as Asparagus officinalis and Asparagus officinalis. It enjoys the reputation of "King of Vegetables" in the international market. Because of its anti-cancer, anti-cancer, immune regulation, and blood lipid-lowering functions, it is very popular among consumers. At present, the asparagus produced in my country is mainly processed into canned asparagus and quick-frozen products except fresh food, but about 30% to 40% of asparagus leftovers are not used in the processing of canned and quick-frozen products, resulting in a large amount of waste of resources and environmental pollution. Asparagus powder, which is used as a functional food ingredient, can be processed from asparagus leftovers after processing as raw materials, which can rea...
