Preparation method of bird's nest lyophilized powder

Abstract

The invention discloses a preparation method of bird's nest lyophilized powder. The preparation method comprises the following steps: S1, mixing bird's nests and water to obtain premix; S2, filteringto remove surplus water and eliminating impurities; S3, after crushing the premix, carrying out sieving treatment; S4, adding water into the sieved premix and boiling; S5, carrying out acidifying treatment; after cooling, adding pepsin and carrying out enzymolysis; S6, adjusting the pH (Potential of Hydrogen) of a mixture to a pre-set value; after filtering, obtaining a bird's nest hydrolysis extracting solution; S7, freezing and drying to obtain the bird's nest lyophilized powder. According to the bird's nest lyophilized powder prepared by the method, bird's nest sialic acid can be released to form a free state and complete releasing of effective active substances is realized; macromolecular protein of the bird's nests can be decomposed into low molecular weight peptide, and the utilization degree of active components and the bioavailability are higher, so that the bird's nests are easily degraded and absorbed by human bodies; after the bird's nests are lyophilized, the mouthfeel of the lyophilized is better; the bird's nests are lyophilized into powder; compared with a conventional bird's nest product, the bird's nest lyophilized powder is convenient to eat, and immersion, feather picking and stewing are not needed; the bird's nest lyophilized powder can be combined with foods including beverages or porridge and the like to realize internal conditioning and health maintenance.

Description

technical field [0001] The invention belongs to the technical field of health product production, and relates to a preparation method of bird's nest products, in particular to a preparation method of bird's nest freeze-dried powder. Background technique [0002] Bird's nest is a nest built by the saliva secreted by swiftlets of the Swiftlet family Swiftlet or saliva mixed with down. [0003] Traditional Chinese medicine believes that bird's nest has the effects of nourishing yin and moistening dryness, nourishing qi, resolving phlegm and relieving cough, and can treat diseases such as chronic illness, consumption, cough, phlegm, coughing up blood, and vomiting blood; modern pharmacological studies have shown that bird's nest not only has extremely rich It also contains a variety of biologically active substances, such as bird's nest acid, bird's nest cell division hormone, epidermal growth factor, etc. These biologically active substances have important biological regulation...

AI Technical Summary

Problems solved by technology

[0004] At present, there are many bird’s nest products on the market, most of which are prepared through a relatively simple rough processing method, mainly to remove impurities such as feathers in the bird’s nest to obtain high-purity protein, or ordinary stewing with sugar water , made into canned form, but the above-mentioned conventional bird’s nest products usually retain almost complete macromolecular proteins, but the macromolecular proteins have the problem of low bioavailability, and the biologically active substances in bird’s nests are tightly combined with glycoproteins and mucins , it is difficult to be degraded and absorbed in the human body, so that their physiological effects cannot be fully exerted

In addition, conventional bird's nest products also have the problems of being difficult to carry and having a bad taste
