Description

Technical Field

[0001] The present invention belongs to the technical field of meat product processing, and specifically relates to a 3D printed selenium-enriched pork product and a preparation method thereof. Background Art

[0002] With the improvement of people's living standards and the enhancement of health awareness, selenium-rich foods have received widespread attention due to their health benefits such as enhancing immunity, anti-oxidation, and anti-cancer. Selenium is one of the essential trace elements for the human body and has multiple biological functions, especially playing an important role in preventing cardiovascular diseases, cancer, and improving immunity. However, the uneven distribution of selenium in nature leads to the fact that the selenium content people consume through their daily diet does not reach the recommended intake. By adding selenium to feed, selenium-enriched pork can be produced, thus providing consumers with a selenium-rich meat food.

[0003] 3D printing technology is an emerging research direction in the field of meat processing. This technology uses 3D printing technology to stack meat raw materials layer by layer to form a specific three-dimensional structure. 3D printing technology can be used to produce meat products with complex shapes and structures, bringing revolutionary changes to the food industry. However, since the tissue structure and texture of pork itself are not suitable for direct 3D printing, pork needs to be processed into minced meat first. The water holding capacity and gel properties of directly minced pork are poor, and it is very easy to cause the loss of selenium in the subsequent processing process. This requires pretreatment of the minced pork used to prepare 3D printed pork products in order to solve this technical defect. Summary of the invention

[0004] In order to improve the 3D printing performance of minced pork and reduce the loss of selenium, the present invention uses the cavitation effect generated by ultrasound to perform ultrasonic treatment on selenium-enriched minced pork. This treatment method can reduce the loss of selenium in the subsequent processing of selenium-enriched minced pork and improve the quality of selenium-enriched pork products. In addition, the method provided by the present invention can also improve its water holding capacity and improve the 3D printing performance of selenium-enriched minced pork. In order to achieve this technical effect, the present invention adopts the following technical solution.

[0008] Furthermore, the raw materials for preparing selenium-enriched pork products are: by weight, 30-40 parts of selenium-enriched pork paste, 0.3-0.6 parts of edible salt, 0.15-0.4 parts of chili powder, 0.05-0.20 parts of pepper powder, and 3-8 parts of water.

[0009] Another aspect of the present invention provides a method for preparing the 3D printed selenium-enriched pork product, the method comprising:

[0010] Grinding the selenium-enriched pork in a meat grinder to obtain selenium-enriched pork mince;

[0011] Weigh the following raw materials by weight: 30-40 parts of selenium-enriched pork mince, 0.3-0.6 parts of edible salt, 0.15-0.4 parts of chili powder, 0.05-0.20 parts of pepper powder, and 3-8 parts of water;

[0012] The weighed raw materials were mixed evenly and subjected to ultrasonic treatment. The ultrasonic treatment conditions were: 200-800W, 15-30min;

[0013] After the ultrasound was completed, the 3D printing device was placed for 3D printing. The printing parameters were: printing temperature 25°C, printing nozzle diameter 1.5mm, each layer height 1.0mm, filling density 100%, printing speed 400mm / min, and wire diameter 20mm.

[0015] Furthermore, in the preparation method, the mincing time is 3 minutes and the mincing speed is 2000 r / min.

[0049] This embodiment provides a preparation method of 3D printed selenium-enriched pork products.

[0050] The raw materials used to prepare the selenium-enriched pork product are as follows: 40 parts of selenium-enriched pork mince, 0.6 parts of edible salt, 0.3 parts of chili powder, 0.12 parts of pepper powder, and 4 parts of water.

[0055] 5. Steam the 3D printed selenium-rich pork product for 10 minutes and cool it to obtain the 3D printed selenium-rich pork product.

[0056] Example 5

[0057] This example describes the selenium content and 3D printing performance of the 3D printed selenium-enriched pork products prepared in Examples 1 to 4.

[0058] Selenium content detection method: The determination method of selenium in selenium-enriched pork is carried out in accordance with the national standard GB 5009.93-2017 "National Food Safety Standard Determination of Selenium in Food". Weigh 0.5g of solid sample (accurate to 0.001g) or accurately transfer 2.00mL of liquid sample, place it in a digestive tube, add 10mL of nitric acid and 2mL of hydrogen peroxide, shake and mix evenly, and digest in a microwave digestion instrument. After the digestion is completed and cooled, transfer the digestion solution to a conical flask, add two glass beads, and continue to heat on the hot plate until it is almost dry. Add 5mL of hydrochloric acid solution (6mol / L), continue to heat until the solution becomes clear and colorless with white smoke, cool, transfer to a 10mL volumetric flask, add 2.5mL of potassium ferrocyanide solution (100g / L), dilute with water, and mix well for testing. Perform a reagent blank test at the same time. Under the same experimental conditions as those for the determination of the standard series solutions, the blank solution and the sample solution are introduced into the instrument respectively, and their fluorescence intensity is measured and quantitatively compared with the standard series.

[0059] According to the above-mentioned selenium content detection method, the selenium content of the selenium-enriched pork products prepared without ultrasonic treatment and the selenium content of the selenium-enriched pork products prepared in Examples 1 to 4 were detected respectively, and the results were statistically analyzed.

[0060] Water holding capacity test method: weigh the sample before steaming and record it as m0. Then steam the selenium-enriched pork at low temperature. After steaming, use double-layer filter paper to absorb the surface moisture. After absorbing the moisture, record the weight as m1 and calculate the steaming loss. The calculation method is as follows:

[0061] Steaming loss = [(m0-m1) / m0] × 100%.

[0062] According to the above method, the water holding capacity of the selenium-enriched pork product prepared without ultrasonic treatment and the selenium-enriched pork product prepared in Examples 1 to 4 were respectively tested.

[0063] Test results: Figure 1 The effect of different ultrasonic conditions on the selenium content of 3D printed selenium-enriched pork products. Figure 1 It can be seen that compared with the samples without ultrasonic treatment, ultrasonic treatment reduces the loss of selenium in the processing of selenium-enriched pork, especially under low-frequency ultrasonic conditions, the 3D printed selenium-enriched pork products have the highest selenium content. The best ultrasonic treatment conditions are: 200W, 20min.

[0064] Figure 2 The effect of different ultrasonic conditions on the water holding capacity of 3D printed selenium-enriched pork products. Figure 2 It can be seen that the cavitation effect produced by ultrasound can destroy the fiber structure in meat products, increase the space between muscle fibers, enhance the ability of meat products to bind water, and improve the water holding capacity of meat products. In addition, ultrasound can also change the protein structure in meat products, making it more able to bind with water molecules, further enhancing the water holding capacity and 3D printing performance of selenium-enriched pork products.

[0065] comprehensive Figures 1-2 It can be seen that the ultrasonic treatment method provided by the present invention can effectively reduce the loss of selenium in selenium-enriched pork mince, improve its water holding capacity, and enhance the 3D printing performance of selenium-enriched pork mince.

[0066] In summary of the above embodiments, the present invention utilizes the cavitation effect generated by ultrasound to perform ultrasonic treatment on selenium-enriched pork mince. This treatment method can reduce the loss of selenium in the selenium-enriched pork mince during subsequent processing, thereby improving the quality of selenium-enriched pork products. In addition, the method provided by the present invention can also improve its water holding capacity and enhance the 3D printing performance of selenium-enriched pork mince. The selenium-enriched pork products provided by the present invention have a high selenium content and good quality.
