Artificial cubilose and preparation method thereof

Abstract

The invention relates to the cross technical field of food science, tissue engineering and biomaterial science, and discloses an artificial cubilose and a preparation method thereof. The preparation method of the artificial cubilose comprises the following steps of: solidifying animal-derived gelatin mixed with epithelial cells into a gel-state culture layer, wherein the epithelial cells comprise salivary gland epithelial cells; constructing a collection layer of an ion interaction macromolecular network structure by polysaccharides and edible gelatin, wherein the polysaccharides comprise positively charged polysaccharides and negatively charged polysaccharides; and placing the culture layer above the collection layer, and immersing the culture layer in a culture medium, so that the collection layer collects cell secretions overflowing from the culture layer. The artificial cubilose is prepared by adopting the above preparation method. The preparation in the invention does not relate to artificial breeding of swallows and does not relate to damage to wild swallows or other natural resources; the nutritional ingredients of the prepared artificial cubilose are not worse than those of natural cubilose; and furthermore, the prepared artificial cubilose almost does not contain substances such as nitrite, heavy metal ions and fungi which are harmful to human bodies.

Description

technical field [0001] The present invention relates to the interdisciplinary technical fields of food science, tissue engineering and biomaterials, in particular to artificial bird's nest and a preparation method thereof. Background technique [0002] Bird's nest is a nest made of saliva and down feathers secreted by swiftlets of the swift family (Apodidae) and various swallows of the same genus, and bird's nest products are bird's nests with feathers and other impurities removed. In traditional medicine, it is believed that it has the functions of nourishing lung yin, reducing phlegm and relieving cough, and regulating deficiency. It is regarded as a good nourishing product in China, Thailand, Singapore, Malaysia and other countries. In China alone, sales in 2020 will reach 50 billion yuan. Natural bird's nests are mainly produced in Southeast Asian countries such as Indonesia, Thailand, and Vietnam. According to the industry standard "Bird's Nest Quality Grade" for China...

AI Technical Summary

Problems solved by technology

[0003] However, the acquisition of natural bird's nest has brought huge ecological environment consumption

First of all, edible bird's nests are made of swiftlets, and swiftlets are still unable to be cultured artificially. Javan swiftlets have soared from "least danger" to "extremely endangered" in the "China Biodiversity Red List"; Secondly, the natural bird’s nest generally takes 4 months to build, and some bird’s nest farms over-collect. In order to collect the bird’s nest as soon as possible, all the hatching mother swallows and eggs are dumped, which seriously damages the reproduction of the bird’s nest; Finally, in the process of forming the natural bird's nest, nitrite will be fermented and formed under the appropriate temperature and humidity, and at the same time, bird droppings containing a large amount of nitrate will also pollute the bird's nest, and even the tyrosine residues of the bird's nest itself and the activity in the environment The nitrogen reaction will also form blood swallows. Even the better natural bird's nests still contain nitrite, heavy metal ions, fungi and other substances harmful to human body, posing health risks
