Description

A kind of pearl shell peptide and its production method
Technical field
The invention belongs to pearl shell peptide field, in particular to a kind of production method of pearl shell peptide.
Background technique
Pearl shell is the main shellfish of China's pearl culture.Pearl shell adopts the shellfish meat left after pearl rich in protein, at present Other than a small amount of fresh eating, be mainly used for being processed into the low value-added product such as feed, can, flavouring, make pearl oyster meat this Valuable natural resources cannot be utilized adequately.
CN101982114A discloses a kind of production method of anti-fatigue oral liquids by using Pinctada martensii dunker meats, is to use high-speed organization Pearl oyster meat is pounded pulpous state by bruisher, and No. 6 light petrol stirring degreasings are added except fishy smell, centrifugation remove No. 6 light petrols, collect precious Pearl shellfish meat slurry adds water and stirs uniformly heating, first adds trypsin digestion by pearl oyster meat slurry quality, inactivates pancreas after the completion of enzymatic hydrolysis Protease;Add papain enzymolysis by pearl oyster meat slurry quality again, inactivates papain after the completion of enzymatic hydrolysis;Then pearl is pressed Shellfish meat slurry quality adds alkali protease to digest, and enzymatic hydrolysis inactivates alkali protease after completing, and is cooled to room temperature;It is collected by centrifugation water-soluble Liquid vacuum concentration, is diluted to properly with sterile water, adds ethylmaltol, citric acid, honey element, is dissolved, and is uniformly mixed and production is made Product.This method is simple for process, and the production cycle is shorter, and pearl oyster meat protein passes through three enzyme composite hydrolysis, the amino of generation Acid and small peptide quantity obviously increase, and are conducive to the raising of product quality.
CN102220402A discloses a kind of method that antibacterial peptide is extracted from pearl oyster meat, includes the following steps: to learn from else's experience Pearl oyster meat is pre-processed, is added after ice water carries out cooled homogenate and obtains homogenate;It is added after flavor protease mixes and adjusts in homogenate The working frequency for saving ultrasonic wave is 35kHz, ultrasonic intensity is 280~360W, temperature is 50~65 DEG C and carries out ultrasonic treatment 90 ~110min;Homogenate after ultrasonic treatment continues to digest 1~2h in 50~65 DEG C of waters bath with thermostatic control, then carries out enzyme deactivation and cold But enzymolysis liquid is handled to obtain;Enzymolysis liquid is subjected to centrifugal treating, taking supernatant to adjust the operating pressure of UF membrane is 2~3bar, temperature Degree is 3~10 DEG C, carries out hyperfiltration treatment using membrane separation technique, collects the separating liquid that molecular cut off is 5000~10000Da, Pearl oyster meat antibacterial peptide product is obtained after freeze-drying.This method is extracted precious with ultrasonic technology auxiliary flavor protease hydrolysis Antibacterial peptide in pearl shellfish meat, it is easy to operate, percent hydrolysis and bacteriostatic activity can be improved, shorten hydrolysis time, production cost is low, produces Product safety can will open the pearl oyster meat resource higher value application discarded after pearl, improve the economic benefit of manufacturing enterprise.
However, problems and disadvantages existing for above-mentioned two pieces application for a patent for invention are as follows: the enzymolysis efficiency of the enzyme of use is low, enzymatic hydrolysis Time is long, and enzyme additive amount is more, needs to adjust optimum pH and optimum temperature is digested, complicated for operation, adjusts peak enzymolysis-ability pH Value can bring a large amount of inorganic ions into, and control peak enzymolysis-ability temperature energy consumption is larger;Use the film core of film filtering for organic material, intolerant to Soda acid, non-refractory high pressure, flux is small, service life is short, and cleaning is inconvenient;The water solubility of prepared pearl shell peptide powder It is poor, moisture absorption agglomeration is easy in storage.
Summary of the invention

(2) it digests: toward described to which the high efficiency compounded enzyme preparate that dosage is raw material weight 0.05~0.15% is added in enzymolysis liquid, 0.5~2h is digested in the case where not adjusting pH value, the natural conditions for not controlling temperature after mixing, obtains thick pearl shell peptide solution; The high efficiency compounded enzyme preparate is by 20~25wt% compound protease, 20~25wt% alkali protease, 20~25wt% Property protease, 20~25wt% flavor protease, 7~8wt% animal proteolytic enzyme and 2~3wt% zymoexciter composition, institute It states zymoexciter and contains reducing agent and bivalent metal ion;The molar ratio of reducing agent and bivalent metal ion in the zymoexciter For 1:(0.5~2);
(3) inorganic nanofiltration ceramic membrane filter: use molecular cut off for the inorganic nanofiltration of 800Da the thick pearl shell peptide solution Ceramic membrane filter, gained permeate are high-purity pearl shell peptide solution;
(4) high temperature high pressure process: the high-purity pearl shell peptide solution is not less than in temperature not less than 110 DEG C, pressure High temperature high pressure process is carried out under conditions of 0.1MPa, obtains treatment fluid;
(5) it is concentrated: the treatment fluid being subjected to heating under reduced pressure concentration, obtains concentrate;
(6) dry powder processed: the concentrate is spray-dried, pearl shell peptide powder is obtained.
2. the production method of pearl shell peptide according to claim 1, which is characterized in that in the zymoexciter reducing agent and The molar ratio of bivalent metal ion is 1:(0.9~1.1).
3. the production method of pearl shell peptide according to claim 1, which is characterized in that the reducing agent is dithiothreitol (DTT) And/or beta -mercaptoethanol.
4. the production method of pearl shell peptide according to claim 1, which is characterized in that the bivalent metal ion is Mg2+、 Zn2+And Ca2+Mixture.
5. the production method of pearl shell peptide according to claim 4, which is characterized in that Mg2+、Zn2+And Ca2+Molar ratio For (0.9~1.1): (0.9~1.1): 1.
6. the production method of pearl shell peptide described according to claim 1~any one of 5, which is characterized in that described inorganic The filter core of nanofiltration ceramic membrane is made using any one material in siliceous, aluminum, magnesia, sa, simatic.
7. the production method of pearl shell peptide described according to claim 1~any one of 5, which is characterized in that the high temperature The condition of HIGH PRESSURE TREATMENT includes that temperature is 110~130 DEG C, and pressure is 0.1~0.3MPa, and the time is 5~20min.
8. the pearl shell peptide that the method as described in any one of claim 1~7 produces.
