Description
Technical field
The invention belongs to technical field of health care products, are related to a kind of preparation method of cubilose product, relate in particular to
A kind of preparation method of bird's nest freeze dried powder.
Background technique
Bird's nest is that the saliva of Apodidae esculent swift secretion or saliva mix with its natural feather and bond built up nest, from ancient times
It is put into rare nourishing top grade, the high-grade tonic as dual-purpose of drug and food is deep to be liked by domestic and international consumer.
Traditional Chinese medicine thinks that bird's nest has nourishing yin to moisten dryness, invigorating middle warmer and replenishing QI, preventing phlegm from forming and stopping coughing and other effects, can control that prolonged illness is deficient, tuberculosis
The diseases such as cough, phlegm asthma, hemoptysis, haematemesis；Modern pharmacological studies have shown that bird's nest not only has profuse nutritional ingredient, also contain
There are many bioactive substance, such as Sialic acid, bird's nest cell division hormone, epidermal growth factor, these bioactive substances
There is important biology regulatory function to human body.
Has the product that is made of many bird's nests on the market at present, majority is by more single rough machined mode system
Standby, the impurity such as natural feather mainly in removal bird's nest obtain the higher albumen of purity or common sweet water adding are stewed, made
At can form, but usually also maintain almost complete high molecular weight protein in above-mentioned conventional bird's nest product, but macromolecular
Albumen has that bioavilability is lower, and the bioactive substance in bird's nest is tightly combined with glycoprotein and mucoprotein,
It is difficult to be degraded and absorbed in human body, the physiological action effect having so as to cause them cannot be given full play to.In addition, conventional swallow
There is also the problems for being difficult to carry, mouthfeel is bad for nest product.
Summary of the invention
For this purpose, the present invention exactly will solve above-mentioned technical problem, to propose that a kind of active constituent is high, be easy to be inhaled by human body
Receive, carry the preparation method of convenient, good mouthfeel bird's nest freeze-dried powder.
In order to solve the above technical problems, the technical scheme is that：
The present invention provides a kind of preparation method of bird's nest freeze-dried powder comprising following steps：
S1, bird's nest, water mixed in proportion, obtains pre-composition, in the pre-composition, the mass ratio of the bird's nest and water is
1:10-30；
S2, it filters out excessive moisture, reject impurity；
S3, the pre-composition grinding and sieving is handled；
S4, boiling is added to boil the pre-composition after sieving；
S5, will boil after pre-composition acidification, after cooling, be added pepsin enzymatic hydrolysis；
The pH for the mixture that S6, regulating step S5 are obtained obtains bird's nest hydrolyzed extract to preset value after filtering；
S7, the bird's nest hydrolyzed extract is freeze-dried, obtains bird's nest freeze-dried powder.
Preferably, freeze-drying described in the step S7 includes：
The bird's nest hydrolyzed extract is freezed 3h under -55--45 DEG C of temperature, the vacuum degree of 20Pa by S71, pre-freeze；
S72, lyophilization are dry for the first time by the bird's nest hydrolysis extract after pre-freeze at -55-0 DEG C；
S73, parsing-desiccation are dry by second of the bird's nest hydrolysis extract after lyophilization at 5-40 DEG C.
Preferably, the detailed process of lyophilization is in the step S72：The successively dry 0.5h at -50 DEG C, -
Each dry 1h at 45 DEG C, -40 DEG C, the dry 3h at -35 DEG C, the dry 4h at -25 DEG C, in -20 DEG C, -15 DEG C, -10 DEG C, -5
DEG C, each dry 3h at 0 DEG C.
Preferably, the detailed process of parsing-desiccation is in the step S73：Successively at 5 DEG C dry 1h, 10 DEG C,
It is separately dried 2h at 20 DEG C, the dry 2.5h at 25 DEG C, the dry 2h at 30 DEG C, the dry 1h at 40 DEG C.
Preferably, the acidification is specifically, using the lemon for accounting for premix mass 0.7-1% in the step S5
The pH value of pre-composition is adjusted to no more than 3 by lemon acid.
Preferably, the cooling is down to 40-50 DEG C for the pre-composition temperature that will be boiled, the enzyme in the step S5
Solution preocess carries out at 40-50 DEG C, and the reaction time is that for 24 hours, the quality of the pepsin and the mass ratio of bird's nest are 1:12-
18。
Preferably, the pH of mixture is adjusted to 5.5-7.5, the carbonic acid by sodium bicarbonate in the step S6
The additive amount of hydrogen sodium is the 8-1.2% of mixture.
Preferably, after mixing bird's nest, water, standing 10h in the step S1, bird's nest being made to be soaked.
Preferably, the step S3 is specifically, cross the processing of 40 meshes for the pre-composition, the step S4 is that will be sieved
Pre-composition add boiling boil 2h.
The above technical solution of the present invention has the following advantages over the prior art：
The preparation method of bird's nest freeze-dried powder of the present invention comprising following steps：S1, bird's nest, water mixed in proportion
It closes, obtains pre-composition, in the pre-composition, the mass ratio of the bird's nest and water is 1:10-30；S2, it filters out excessive moisture, reject
Impurity；S3, the pre-composition grinding and sieving is handled；S4, boiling is added to boil the pre-composition after sieving；S5, after boiling
After cooling, pepsin enzymatic hydrolysis is added in pre-composition acidification；The pH for the mixture that S6, regulating step S5 are obtained to preset value,
Bird's nest hydrolyzed extract is obtained after filtering；S7, the bird's nest hydrolyzed extract is freeze-dried, obtains bird's nest freeze-dried powder.Using
The bird's nest freeze-dried powder of this method preparation, can be such that bird's nest sialic acid releases as free state sialic acid, realize effective active matter
Complete release, the high molecular weight protein of bird's nest is decomposed into as small-molecular peptides, and active constituent and bioavilability are higher, are easy quilt
Human body degradation absorbs, and reaches its pharmacological action, and after freeze-drying, the mouthfeel of bird's nest more preferably, bird's nest is lyophilized as powdery, with conventional bird's nest
Product is compared, convenient, without impregnating, choosing hair and stew, in combination with raising life in the food such as drink or clear congee.
