Description
Technical Field
The invention belongs to the technical field of novel food processing. More particularly, relates to a 3D printing shrimp paste-grease composition and a preparation method thereof.
Background
Three-dimensional rapid prototyping printing, referred to as 3D printing for short, is a technology of designing a 3D model using computer software and manufacturing a three-dimensional product by adding materials layer by layer through a 3D printer. The method is different from the material reduction manufacturing of the traditional manufacturing industry, and has the characteristics of rapidness, convenience, flexibility, high precision, high quality, low cost and the like. The 3D printing technique has advantages in that objects of any shape can be generated directly from computer graphic data without machining or molds, and shapes that cannot be manufactured by conventional food production techniques can be manufactured. Under the condition of having good design concept and design process, the method greatly shortens the food development and processing period, obviously improves the production efficiency and reduces the production cost.
However, the 3D printing technology has special requirements for production materials, the printing materials are required to be liquid, pasty or powdery, and a good 3D printing effect can be obtained only when certain viscosity, fine density and rheological properties are achieved, so that the application of the 3D printing technology in the field of food production is greatly limited. At present, only a few studies have been made on the preparation of minced meat of livestock and poultry and seafood by using a 3D printing technology, for example, chinese patent application CN106798263A discloses a control method for improving the 3D accurate printing performance of a thawed minced fillet system forming agent, and the method needs to use flaxseed gum and gluconolactone to induce the minced fillet gel to have stable viscosity and fluidity; chinese patent application CN109077259A discloses a preparation method of a minced shrimp material for 3D printing, which adds starch into minced shrimp, not only can increase the gel strength and elasticity of the minced shrimp, but also can reduce the viscosity of the minced shrimp, and the prepared minced shrimp material has good fluidity, fine slurry and small possibility of blocking a 3D printer. Although the addition of the gum substance or the starch substance can improve the properties of the meat paste so that the meat paste can be printed and reduce the blockage of a printing nozzle, in practical application, the problems of collapse, depression, shape change and the like in different degrees can occur after the meat paste is printed and formed for a period of time, and the stability is poor.
Therefore, the 3D printing shrimp paste-grease composition with good rheological property, water retention property and texture property is urgently needed to be provided, so that the shrimp paste product obtained by printing has high printing accuracy, good stability and strong support property, and the 3D printing adaptability of the shrimp paste is improved.

Detailed Description
The invention is further described with reference to the drawings and the following detailed description, which are not intended to limit the invention in any way. Reagents, methods and apparatus used in the present invention are conventional in the art unless otherwise indicated.
Unless otherwise indicated, reagents and materials used in the following examples are commercially available.
Data in the present invention are expressed as mean ± standard deviation and analyzed using the general linear model program of statistical software.

All measurements were repeated three times for each batch of samples.
Example and comparative example 3D printing shrimp paste-oil composition
The 3D printing shrimp paste-oil composition of the examples and comparative examples was made from shrimp paste, salt 3% by mass of the shrimp paste, cooking wine 3%, monosodium glutamate 1%, white granulated sugar 1%, and oils (lard LO, soybean oil SO, olive oil OO), wherein the oils and their amounts added are shown in table 1.
Table 1 examples 1 to 93D oils and fats and amounts added of oil and fats of shrimp meat paste-oil composition for printing
The preparation method of the 3D printing shrimp paste-grease composition comprises the following steps:
under the condition of 2-5 ℃, performing conventional pretreatment on fresh shrimps, such as removing heads, shells and intestinal glands to obtain shrimp meat, firstly conducting air-kneading for 5min, adding salt accounting for 3% of the mass of the shrimp meat paste, kneading for 2min, then adding cooking wine accounting for 3% of the mass of the shrimp meat paste, 1% of monosodium glutamate and 1% of white granulated sugar, kneading for 2min, and finally adding grease, and kneading for 2 min.
Experimental example 1 composition 3D printing accuracy and stability
3D printing is carried out on the 3D printing minced shrimp-grease composition of the examples 1-9 and the comparative example 1 by using a spray head with the diameter of 1.20mm, the forming effect of a printed product is recorded by taking pictures in an LED lamp box, the side length and the height of the printed product are measured by using a vernier caliper, and the printing accuracy is evaluated by using the ratio of the length of a printed object to the length of a model compared with the ideal size of a target model. All printed products are placed in an environment with room temperature of 25 ℃ for 60min to measure the height and calculate the printing stability index of the products.
In the formula: l issIs the sample side length (mm); l ismIs the side length (mm) of the model; h0minHeight of sample (mm) at 0 min; h60minThe height (mm) of the sample at 60 min.
See fig. 1 and table 2 for experimental results.
As can be seen from FIG. 1, in comparative example 1 (without grease), the lines are rough, the layers are loosely stacked, the bottom has structural collapse, and the printing effect is poor; when the types of the grease are the same, the addition amount is 4-6%, the 3D printing effect of the composition can be improved more remarkably, but when the addition amount of the grease is increased continuously, the support between the printing layers of the sample is weakened, so that the printing accuracy is reduced, and the printed product can collapse to different degrees after being placed for 60 min; when the addition amount of the grease is the same, the lard group has better effect.
TABLE 2 measurement of accuracy and stability of 3D printed products of compositions
Note: different letters in the same index showed significant differences (P < 0.05).
As can be seen from table 2, the printing accuracy and the printing stability of the grease-added composition are higher than those of the grease-not-added composition, and the printing accuracy and the printing stability gradually increase with the increase of the addition amount of the grease, because the minced shrimp meat added with the grease has certain fluidity, the grease has a certain lubricating effect, the friction between the sample and the printing material cylinder is reduced, and the sample is easier to print; however, when the amount is too large, the support between the printed layers of the sample is weakened, so that the printing accuracy is lowered. The comparison shows that the printing product with the grease addition of 4-6% still maintains the original shape and height after being placed for 60min, and basically has no collapse, while the printing product in the comparative example 1 has collapse and deformation in different degrees; wherein, when 4% lard is added, the printing accuracy and the printing stability are both higher.
Experimental example 2 determination of rheological Properties of the composition
Measurement examples1-9 and comparative example 1 compositions static apparent viscosity rheology, dynamic rheology, apparent viscosity (. eta.) and rheological Unit Link Strength (A)F)。
Wherein, the determination of the static apparent viscosity rheological curve: the measurement is carried out by adopting a model HAAKE MARS III modularized advanced rheometer (Thermo Fisher Scientific company, USA), wherein the model P35Ti L of the rotor is set at 25 ℃, the diameter of a flat plate is 20mm, the gap is 1mm, and the shear rate range is 0.1-100 s-1The change in apparent viscosity with shear rate was determined and the results are shown in FIG. 2, while the values for apparent viscosity (. eta.) are recorded and the results are shown in Table 3.
Determination of dynamic rheological curves: the measurement is carried out by adopting an HAAKE MARS III model modularized advanced rheometer (Thermo Fisher Scientific company, USA), the frequency scanning test is carried out, the rotor model P35Ti L is set at 25 ℃, the strain scanning is 0.1%, the change conditions of the elastic modulus G 'and the viscous modulus G' along with the oscillation frequency are measured, and the results are shown in figures 3-4.
Comprehensive modulus (G) according to material resistance to extrusion deformation*) Analysis and fitting to obtain AFThe value:
in the formula: a. theFRepresents the strength of the connection between the rheological units; z represents the number of rheological units. And A isFThe values are reported in Table 3.
TABLE 3 apparent viscosity of the composition and AFMeasurement results of values
Note: different letters in the same index showed significant differences (P < 0.05).
As can be seen from FIG. 2 and Table 3, the compositions exhibited shear thinning and the apparent viscosity of the system decreased with increasing shear rate, indicating that the compositions are typically pseudoplastic fluids (n < 1). At a certain shear rate, the apparent viscosity of the grease composition is higher than that of the sample without grease; when the types of the grease are the same, the apparent viscosity of the grease is gradually increased along with the increase of the addition amount, and the proper apparent viscosity is reached when the addition amount of the grease is 4-6%, so that the discharging continuity of the composition during printing can be ensured, and the problem of filament breakage in the sample printing process is solved.
As can be seen from fig. 3 to 4 and table 3, the elastic modulus and the viscous modulus of the minced shrimp meat can be improved by different types of oil, and the elastic modulus and the viscous modulus of the sample increase with the increase of the addition amount of the oil. For the same kind of grease, the elastic modulus G ' is gradually increased along with the increase of the added amount, the viscous modulus G ' and the elastic modulus G ' have similar change trends, and the elastic modulus G ' of all samples is higher than the viscous modulus G ', which indicates that the elasticity of the composition is larger than the viscosity and is dominated by the elasticity. As the amount of the added fat or oil increases, AFThe values also gradually increased, indicating a gradual increase in the ability of the composition to link strength of the rheological unit: when A isFThe value is 2500 to 4500Pa.S1/zIn time, the shrimp paste printed well (as in examples 1-9), thus controlling the A of the materialFThe value is 2500 to 4500Pa.S1/zThe 3D printing adaptability of the shrimp meat paste can be effectively improved, so that the printing accuracy of a 3D printing product reaches over 90%, and the printing stability reaches over 91%.
Experimental example 3 measurement of Mass-structural Properties of composition
The compositions of examples 1-9 and comparative example 1 were placed in a beaker and three texture properties of hardness, elasticity and adhesion of the sample were determined using TPA full texture analysis. The instrument was calibrated with a 1kg load cell and the test probe was P/0.5. The sample testing parameters were as follows: the height of the probe raised to the surface of the sample was 30mm, the compression set was 50%, the detection speed was 60mm/min, and the initial force was 0.5N, and the results are shown in Table 4.
TABLE 4 measurement results of texture Properties of the compositions
Note: different letters in the same index showed significant differences (P < 0.05).
As can be seen from Table 4, the hardness, adhesiveness and elasticity of the sample tended to increase with the increase in the amount of the added fat, and the hardness, adhesiveness and elasticity of the composition were significantly higher than those of the other added amounts when the amount of the added fat was 6%. The printing effect is combined, when the addition amount of the grease is 4-6%, the hardness, the adhesion and the elasticity of the composition are moderate, the blockage of a printing nozzle can be reduced, the laminating property between layers of the 3D printing is improved, and the adaptability of the 3D printing is improved.
Experimental example 4 measurement of moisture distribution State of composition
Determination of the moisture State (T) of the composition by means of a Low-field Nuclear magnetic resonance apparatus (LF-NMR)2) The resonance frequency and the magnetic field strength were set to 22MHz and 0.47T, respectively. The detection steps are as follows: about 10g of the compositions of examples 1 to 9 and comparative example 1 were placed in a petri dish with a diameter of 35mm, and a sample was scanned by using a Caar-Purcell-Meiboom-Gill (CPMG) pulse sequence to obtain a transverse relaxation time T2(ii) a The set parameters of the CPMG sequence are specifically as follows: TW is 3000ms, SW is 100KHz, NS is 8, TE is 0.400ms, and NECH is 2000. After the test is completed, the number of iterations is set to 105And inverting the obtained curve to T2See figure 5 and table 5 for the results.
As can be seen in FIG. 5, the relaxation time of the low-field NMR of the composition is divided into two peaks corresponding to two states of water, i.e., bound water (T;)2b) And hardly flowing water (T)21)。
TABLE 5 measurement results of moisture distribution state of the composition
Note: different letters in the same index showed significant differences (P < 0.05).
As can be seen from Table 5, the relaxation time T of the oil or fat composition added2b、T21Obviously reduces the content of the water and the oil, and the reduction degree is similar, which shows that the added oil is beneficial to stabilizing the bound water in the shrimp meat paste and is not easy to flow water; different kinds of oils T2bCorresponding peak area A2bAre all increased by T21Corresponding peak area A21A corresponding decrease was also shown, indicating that the less mobile water in the composition was converted to bound water, probably due to the fact that the interaction between water, protein, colloids in the minced shrimp meat changed and the sites available for binding water increased, resulting in an increased amount of bound water and a decreased amount of less mobile water, but overall, the addition of fat increased the water retention of the sample.
Experimental example 5 measurement of Water-holding Properties of composition
The compositions of examples 1-9 and comparative example 1 were weighed (W)1) Freezing and centrifuging (10000r/min, 4 ℃) for 10min, absorbing surface moisture by filter paper after centrifuging, and weighing again (W)2) And calculating the water holding rate according to a formula: WHC (%) ═ W2/W1X 100%, the results are shown in Table 6.
TABLE 6 measurement results of Water holding Properties of compositions
Note: different letters in the same index showed significant differences (P < 0.05).
As can be seen from table 6, for the same oil, the water holding capacity of the sample increased with the increase in the amount added; the printing effect is combined, when the addition amount of the grease is 4-6%, the water binding capacity of the composition is moderate, and the 3D printing adaptability is improved.
