Freeze-dried cubilose making method

Abstract

The invention discloses a freeze-dried cubilose making method, and relates to the technical field of cubilose freeze-drying, the method comprises the following steps: S1, soaking treatment: preparing a container, removing cubilose feet and a bottom support from the collected cubilose cup, placing the cubilose in the clean container, taking purified water to wash the cubilose from top to bottom under the flushing water pressure of 0.4 MPa until the cubilose is completely covered by the purified water, and soaking the cubilose; and S2, cleaning treatment: lightly removing swallow feather and impurities by using tweezers, putting the cubilose into a container, adding purified water at the temperature of 24-40 DEG C, stirring the cubilose to enable fine fluff in the cubilose to float on the water surface, and then cutting the container to be inclined by 45 degrees. According to the invention, desorption drying and freeze drying are added for cooperative use, so that the drying treatment in two stages is realized, the water content of the freeze-dried cubilose is reduced to the greatest extent, the water content of the freeze-dried cubilose is prevented from exceeding the standard, the shelf life of the freeze-dried cubilose is prolonged, and the freeze-dried cubilose is convenient to package and store.

Description

technical field [0001] The invention relates to the technical field of bird's nest freeze-drying, in particular to a preparation method of freeze-dried bird's nest. Background technique [0002] The bird's nest is the nest of the seabird swiftlet, which is mostly built on the cliffs of tropical and subtropical islands, surrounded by rolling waves, and above the blue sky and white clouds. Swiftlets start to make nests in spring, and their mouths can secrete a A kind of colloidal saliva, after being spit out and dried by sea breeze, it becomes a translucent and slightly light yellow substance, which is the main component of bird's nest. Modern medical research has found that the main components of bird's nest are water-soluble protein, carbohydrates, trace elements , calcium, phosphorus, iron, sodium, potassium and amino acids, lysine, cystine and arginine that play an important role in promoting human vitality, 1000 grams of dry bird's nest contains 499 grams of protein, 429 ...

AI Technical Summary

Problems solved by technology

[0003] The prior art has the following deficiencies: the existing freeze-dried bird’s nest is generally stewed together with a variety of auxiliary materials, and when one of the auxiliary materials expires, the entire freeze-dried bird’s nest product cannot be used. The long-term preservation of bird's nest is inconvenient to mix according to the taste of the eater. The concentration of bird's nest is relatively low, and the reasonable intake of bird's nest nutrition is not used. In the freeze-drying process, there is only the first stage of drying and freezing. In the freeze-dried bird's nest In the packaging stage after the sublimation of water, the freeze-dried bird’s nest may still be exposed to the air, causing the water vapor in the air to condense on the surface of the freeze-dried bird’s nest, so that the water content of the freeze-dried bird’s nest will be too high again during packaging. It is inconvenient to keep freeze-dried bird's nest for a long time
