After the bird's nest silk is treated by the glutamine transaminase, the crosslinking degree among protein molecules in the bird's nest silk is improved, the protein denaturation further enables the internal structure of the bird's nest silk to be more compact, the protein denaturation and the protein denaturation synergistically act to improve the heat stability of the bird's nest silk during high-temperature sterilization, the bird's nest silk is insoluble during high-temperature sterilization and later storage, and the phenomenon of water melting of the bird's nest silk cannot occur.
Description
Technical Field
The invention belongs to the technical field of food processing, and particularly relates to a preparation method of convenient and instant cubilose and a product thereof.
Background
The bird's nest is formed by coagulation of saliva of swiftlet of the family delphinidae and saliva of the same genus or mixed saliva of velvet and the like, is a famous and precious traditional Chinese medicine, and has unique curative effects of nourishing yin, moistening dryness, tonifying middle-jiao and Qi, invigorating stomach and spleen, stopping bleeding due to trauma, reducing phlegm and stopping cough and the like. The cubilose contains abundant natural nutrient components such as mucin, protein, sialic acid, calcium, phosphorus, vitamin A, D, E, K and the like. Among them, mucin is a component of cellular protoplasm, connective tissue and some enzymes, and is very important for the physiological action of the human body; sialic acid is also called neuraminic acid, and has physiological effects of improving intelligence and memory of infants, resisting senile dementia, resisting recognition and virus, and improving the absorption of vitamins and minerals by intestinal tract.
The edible bird's nest has a semitransparent thread-shaped structure, has strong water holding capacity after being stewed in boiling water, can absorb water 4-8 times of the weight of the edible bird's nest, and has fine and smooth mouthfeel. The protein content of the cubilose is high, and the cubilose can with long shelf life needs to be sterilized at high temperature to ensure the safety of the product.
However, the bird's nest silk is not high temperature resistant, and is easily dissolved in water during high temperature sterilization. The dissolved bird's nest silk not only causes the solid content reduction in the product, but also loses the taste and texture of the bird's nest, and meanwhile, the disappearance of the bird's nest silk can cause the doubt of the consumer about the authenticity of the product. In order to improve the stability of the internal organization structure of the edible bird's nest silk, patent CN105325797A discloses a method for processing edible bird's nest soft cans by steaming and sectional sterilization technologies, which comprises the processes of soaking, ultrasonic impurity removal, cleaning and blow-drying, steaming, moisture regain, subpackaging and filling, soft can sealing, back pressure sectional sterilization, cooling, finished product detection, warehousing and the like.
Disclosure of Invention
This section is for the purpose of summarizing some aspects of embodiments of the invention and to briefly introduce some preferred embodiments. In this section, as well as in the abstract and the title of the invention of this application, simplifications or omissions may be made to avoid obscuring the purpose of the section, the abstract and the title, and such simplifications or omissions are not intended to limit the scope of the invention.
The present invention has been made keeping in mind the above and/or other problems occurring in the prior art.
Therefore, aiming at the problems that the cubilose shreds are easy to dissolve in the high-temperature sterilization process and the subsequent storage process and the like, the invention develops the convenient instant cubilose and the preparation method thereof based on the existing product form, the basic theory and a large amount of experimental research of the cubilose, so that the cubilose shreds are not dissolved in the high-temperature sterilization and later-period storage process, still can exist in a filiform, and have fine and smooth mouthfeel.

TABLE 1
As can be seen from table 1, when the bird's nest silk is directly sterilized at high temperature without treatment, the solid content obtained after sterilization is low, the water-melting phenomenon occurs during storage, and the solid content is completely melted after 6 months of storage, so that the bird's nest silk disappears. After the bird's nest silk is subjected to the denaturation treatment of glutamine transaminase and acid, the bird's nest silk and the acid transaminase are subjected to synergistic action, so that the internal structure of the bird's nest silk is tighter, and the thermal stability during high-temperature sterilization and the solid content during storage are improved.
Examples 6 to 8
On the basis of example 1, the influence of different treatment conditions on the solid content and sialic acid content was investigated.
TABLE 2
As can be seen from table 2, the concentration of transglutaminase and pH at the time of acid shrinkage have a large influence on the content of solids after sterilization during the period when the content of solids has been stored, and when the concentration of transglutaminase is too low, the degree of cross-linking between molecules of bird's nest protein is low, and the content of solids at the later stage is low; when the pH value of the system is too low, the bird's nest silk structure shrinks too tightly, so that the good water holding performance of the bird's nest is lost, the smooth mouthfeel of the bird's nest is lost, the solid content of the bird's nest is reduced, and meanwhile, when the pH value is too low, sialic acid is hydrolyzed from the bird's nest protein molecules, so that the nutritional value of the bird's nest is reduced. Preferred conditions for internal crosslinking in the present invention: 2-3% of glutamine transaminase, 40-50 ℃ of treatment temperature and the condition of structure shrinkage: the concentration of the sulfuric acid solution is 0.05mol/L, the treatment temperature is 80 ℃, the time is 40min, and the purity and the yield of the obtained sialic acid product reach the best effect.
Examples 9 to 10
On the basis of example 1, the influence of different treatment conditions on the solid content and the sialic acid content was investigated, and the conditions and results of examples 9 to 10 are shown in table 2.
TABLE 2
As can be seen from Table 2, after the bird nest silk is subjected to the glutamine transaminase and acid denaturation treatment, the bird nest silk and the acid transaminase act synergistically to enable the internal structure of the bird nest silk to be more compact, and the heat stability during high-temperature sterilization and the solid content during storage are improved. The inventor further researches and discovers that after the bird's nest silk is treated by the glutamine transaminase, the crosslinking degree of protein molecules in the bird's nest silk is improved, the pH value of a system is adjusted to 2, the internal structure of the bird's nest silk is further enabled to be more compact, the bird's nest silk and the protein molecules act synergistically, and the thermal stability of the bird's nest silk during high-temperature sterilization is improved. Meanwhile, when the pH value is adjusted to be acidic, a part of sialic acid is hydrolyzed from cubilose protein molecules, so that the nutritional value of cubilose is reduced.
Aiming at the problems that the cubilose shreds are easy to dissolve in the high-temperature sterilization process and the subsequent storage process and the like, the invention develops the convenient instant cubilose and the preparation method thereof based on the existing product form, the basic theory and a large amount of experimental research of the cubilose, so that the cubilose shreds are not dissolved in the high-temperature sterilization and later-period storage process, can still exist in a filiform form, and can ensure fine and smooth mouthfeel.
The invention provides a preparation method of convenient and instant cubilose, which is characterized in that cubilose filaments are treated by glutamine transaminase, so that the crosslinking degree of protein molecules in the cubilose filaments is improved, the pH value of a system is adjusted to 0-5, protein denaturation is further realized, the internal structure of the cubilose filaments is more compact, the cubilose filaments and the protein denaturation are synergistic, the thermal stability during high-temperature sterilization is improved, the cubilose filaments are not dissolved during high-temperature sterilization and later storage, and the problem of water melting of the cubilose filaments is avoided. After the treatment of glutamine transaminase, compared with the single acid denaturation treatment, the content of sialic acid is improved during the acid denaturation treatment, and the internal structure of the bird's nest silk is more compact and has inhibiting effect on the loss of sialic acid probably because the bird's nest silk is subjected to the glutamine transaminase and acid denaturation treatment. According to the invention, through glutamine transaminase treatment, the subsequent pH value of the system is adjusted, and corresponding parameters are optimized, so that the difficult problem of bird's nest filamentation water is avoided, the loss of sialic acid is reduced, and the nutritional value of the bird's nest is improved.
