Description
Technical field
The invention belongs to food processing technology field, and in particular to a kind of integrated debubbling method of bird's nest protein liquid.
Background technology
Bird's nest contains abundant protein, polysaccharide, lipid, trace element and sialic acid etc., has nourishing yin to moisten dryness, bowl spares benefit
Gas, enter the functions such as stomach tonifying spleen, preventing phlegm from forming and stopping coughing, there is higher edible and medical value.Bird's nest is in transport or process
It is easily broken, it is broken produces substantial amounts of bird's nest.Bird's nest is broken to can be used for processing bird's nest oral liquid, bird's nest polypeptide, bird nest drink, bird's nest tank
The product such as head and remodeling type bird's nest.Protein content accounts for the 55%-65% of bird's nest dry weight in bird's nest, is preparing bird's nest protein liquid process
In, when solution is by rapidly stirring, to keep stable system and heat endurance, protein molecular is adsorbed to liquid-vapor interface reduction
Surface tension.The protein molecule hydrophilic radical at interface is in towards aqueous phase, while in the unfolded rearrangement exposure of protein molecule
Portion's hydrophobic grouping is adsorbed to interface, when a large amount of gas molecules are mixed into, produce the network structure for including gas, that is, produces bubble.
The generation of foam can cause the problems such as bird's nest protein loss, unstable product quality, difficult pollution process equipment and sealed cans sterilizing.
Therefore, in bird's nest protein liquid process, the application of defoaming technology is particularly important.
At present, the mode of protein liquid defoaming mainly has chemical defoaming method and physical defoaming method.Chemical defoaming method generally use
Be the chemical defoamer of addition, the defoamer that domestic and international food industry uses has polyether antifoam agent, N-type defoamer, organosilicon to disappear
Infusion, sucrose-fatty esters defoamer and compound defoamer etc..Chemical defoaming method in food industry applications predominantly
Position, but the use of defoamer can reduce the quality of product, and certain harm can be produced to health.Physical defoaming method is main
There are settled process, temperature-raising method, decompression method, mechanical mixing method, fluid injection method, supercritical ultrasonics technology and high voltage pulse method etc., physical defoaming
Method has no effect to product, can be as the preferable alternative of chemical defoamer, but the problems such as defoaming effectiveness is low be present.
The content of the invention
It is an object of the invention to provide a kind of integrated debubbling method of bird's nest protein liquid, it digests skill by integration section
The high low speed of art, vacuum beats suds technology and high/low temperature defoaming technology, solves easily a large amount of in bird's nest protein liquid process rise
Caused by bubble the problems such as unstable product quality, bird's nest protein loss, difficult sealed cans sterilizing, a kind of bird's nest egg of high-quality is made
White liquor.
To achieve the above object, the present invention adopts the following technical scheme that：
A kind of integrated debubbling method of bird's nest protein liquid, it is that the bird's nest liquid that bird's nest adds water to be obtained after stewing first is used into 0.1mol/L
NaHCO3Solution regulation pH value to 8, then addition alkali protease carry out Partial digestion, are cooled down after boiling water enzyme deactivation 3min, then
Beaten through the high low speed of vacuum and high/low temperature defoams circular treatment 3 times.
Wherein, the bird's nest is that dry bird's nest is broken.
The mass concentration of the bird's nest liquid is 1-3%.
The Partial digestion is that enzyme activity is added in bird's nest liquid after adjustment of ph as 2 × 105 U/g alkali protease,
Its addition is the 0.03%-0.05% of bird's nest dry weight, and 30-90min is then digested under the conditions of 40-60 DEG C, is hydrolyzed to enzymolysis liquid
Spend for 5%-15%.
It is that the enzymolysis liquid after enzyme deactivation, cooling is fitted into vacuum beetling machine that the high low speed of the vacuum, which is beaten, 5-15 DEG C, very
Under conditions of reciprocal of duty cycle is 0.06-0.08MPa ,/min low speed whipping 1-2min is turned using 3000-5000, then using 10000-
12000 turns/min beats at a high speed 1-2min.
The high/low temperature defoaming is that the enzymolysis liquid after whipping is heated into 85-100 DEG C, and constant temperature keeps 1-2min, then drops
For temperature to 5-15 DEG C, constant temperature keeps 1-2min.
The remarkable advantage of the present invention is：
（1）As shown in Figure 1, 2, the foaming characteristic of bird's nest protein liquid increases with the extension of enzymolysis time, and foam stability with
The extension of enzymolysis time and significantly reduce.Compared to foaming characteristic, influence of the foam stability to protein bubbling character is more
Significantly.The present invention uses bird's nest protein part zymolysis technique, greatly reduces the foam stability of bird's nest albumen, i.e., is not reducing
Bird's nest nutrient protein improves its bubbling character on the premise of being worth, so as to be advantageous to subsequently carry out suds and defoaming to it.
（2）The present invention beats suds technology using the high low speed of vacuum, can reduce contact of the bird's nest albumen with air, reach suppression
The effect of foam generation processed, meanwhile, changed altogether using pressure, shearing force, compression stress and impulsive force caused by the whipping of high low speed
With the purpose for reaching defoaming.
（3）Under different temperature conditionss, different degrees of dissociation and aggregation can occur for bird's nest albumen, influence protein and exist
Gas-liquid interface it is amphipathic so that foam is unstable, therefore, is handled using high/low temperature and can reach the purpose of defoaming；
（4）The integrated bird's nest protein part zymolysis technique of the present invention, the high low speed of vacuum beat suds technology and high/low temperature defoaming technology,
Solve unstable product quality, bird's nest protein loss, sealed cans caused by easily largely being bubbled in bird's nest protein liquid process
Sterilize difficult technical bottleneck, and its technical operation is simple, does not add that chemical defoamer, defoaming effect are good, product quality is high, is bird's nest
The exploitation of new product has put forward a new way.
Brief description of the drawings
Fig. 1 is influence of the different enzymolysis times to bird's nest protein liquid foaming characteristic.
Fig. 2 is influence of the different enzymolysis times to bird's nest protein liquid foam stability.
