Embodiment 1

[0092] Embodiment 1, a kind of processing technology of vacuum freeze-dried asparagus instant powder, the steps are as follows:

[0093] (1) Raw material selection: choose asparagus waste materials with emerald green color, good plumpness and no rot.

[0094] (2) Thawing: put the waste asparagus into a beaker, and thaw naturally at room temperature for 30 minutes.

[0095] (3) Juicing: the thawed asparagus waste was squeezed with a juicer, and distilled water was added to adjust the concentration to 20%.

[0096] (4) Preparation: put 6% sucrose by mass and 0.35% citric acid by mass into cold water and stir until uniform, put maltodextrin with 13% by mass in hot water, heat and stir continuously until dissolved, Then, according to the order of 6% fresh milk, sucrose and citric acid respectively by volume, they are added into the asparagus juice in different amounts and stirred evenly.

[0097] (5) Pre-freezing: put the asparagus juice into a freezing tray, spread it flat, and...

Abstract

The invention relates to a technology for processing a food which takes asparagus as raw material, in particular to a technology for processing vacuum freeze-dried asparagus instant powder. The technology solves the technical problem of processing and re-utilizing the waste material of the asparagus. The steps are as follows: (1) extracting juice from the raw material; (2) preparing; (3) pre-freezing; and (4) vacuum freeze-drying. The technology utilizes the vacuum freeze-drying method for producing the asparagus instant powder and can keep nutritional components to the maximum extent and meetthe demands of a human body; and meanwhile, the product developed by tests is not added with any preservatives or pigments and has safe and convenient taking, good soakage property, and the product is in line with the development direction of nature, nutrition and back to nature and increases the utilization rate and the economic benefits of the asparagus.

Description

technical field [0001] The invention relates to a food processing technology using asparagus as raw material, in particular to a processing technology of vacuum freeze-drying asparagus instant powder. Background technique [0002] Asparagus is one of the top ten vegetables in the world. It is commonly known as asparagus and asparagus. It is a perennial perennial plant of the genus Lily Asparagus. It is native to the Mediterranean and later spread to Asia and other places. [1] , Asparagus is eaten with tender stems, with fresh texture, delicious flavor, tender and delicious. In addition to serving meals, increasing appetite, aiding digestion, and supplementing vitamins and minerals, because it contains more asparagine, aspartic acid and other saponins [2] , can prevent and fight cancer, and has curative effects on cardiovascular diseases, edema, bladder and other diseases. In "Shen Nong's Materia Medica", asparagus is listed as "the top grade", second only to ginseng, and i...
