Embodiment

[0016] Bird's nest extraction steps are as follows:

[0017] Step 1: Take the bird's nest and take it to a spray washing machine and spray it until there are no black spots to obtain bird's nest residue; or directly spray the bird's nest with water without adding any preparations;

[0018] Step 2: Extract the bird’s nest slag, put it in a white steel basin, pour pure water until the bird’s nest is completely submerged, the ratio of purified water to bird’s nest is 1:10, put it in an electric oven and bake for 100 hours, and the bird’s nest slag will completely melt in the water;

[0019] Step 3: Lift the completely melted bird's nest slag to the filter for filtration, collect the filtrate and filter residue, the stainless steel sieve size in the filter: 0.15mm, the mesh number is 100 mesh;

[0020] Step 4: Obtain the mixed concentrated filtrate and filter residue, remove it to a freeze dryer, and freeze-dry at -80°C for 5 hours until completely dry.

[0021] The bird's nest e...

Abstract

The invention discloses an extraction technology of bird's nests. The extraction technology comprises the following steps of thoroughly cleaning hairy bird's nests, putting the cleaned bird's nests into a basin, pouring purified water until the bird's nests are completely immersed by the purified water, putting the immersed bird's nests into an electric oven, performing baking, after the bird's nests completely melt, putting the melted bird's nests into a filter, performing filtration, collecting filtrate and filter residues, conveying the filtrate into a freeze dryer, and performing freeze-drying until the filtrate is completely dried. The processing technology disclosed by the invention is simple in steps, high in extraction quantity and environmentally-friendly, and the content of sialic acid in extraction substances of the bird's nest by the technology is high.

Description

technical field [0001] The invention relates to the field of bird's nest processing, in particular to a bird's nest extraction process. Background technique [0002] The reason why bird's nest has extremely high nutritional value is largely because bird's nest is rich in sialic acid. The existing bird's nest extraction method is mainly to ultrasonically pulverize the bird's nest, then add enzyme hydrolysis, further centrifuge, freeze-dry after drying. In addition to the enzymatic hydrolysis step, the existing technology also requires pretreatment steps such as crushing, soaking, boiling, and pH adjustment to improve the efficiency of hydrolysis, and subsequent processing steps such as centrifugation, filtration, and drying to treat the hydrolyzate. To get bird's nest extract. At present, this treatment method has a complicated process and low product yield. The bird's nest extract obtained by this method not only has a low content of cosmetic active ingredients, but may a...
