Abstract
Description
Technical Field
[0001] The invention relates to the field of food production technology, and in particular to a sliced luncheon meat and a production method thereof. Background Art
[0002] The mainstream luncheon meat on the market adopts the cooked packaging process, that is, first cooked, then sliced, and then sterilized again. The main process is as follows:
[0003] Preparation of minced meat: chop pork (lean meat + fat meat) and add ingredients (brine, phosphate, starch, etc.).
[0004] Molding and steaming: The minced meat is put into a metal mold and steamed at high temperature (80-90 degrees Celsius) to form a solid structure.
[0005] Cooling and slicing: Slice the cooked luncheon meat after cooling it to form sliced specifications.
[0006] Packaging and secondary sterilization: Put the sliced luncheon meat into a cooking bag and sterilize it again at high temperature (121 degrees Celsius, 15-30 minutes) to extend the shelf life.
[0007] Cooling and storage: After high-temperature sterilization, the product is quickly cooled and enters the cold chain storage link.
[0008] The recipe for luncheon meat slices uses compound seasonings instead of MSG based on the Meilin recipe. The research and development focus is mainly on overcoming the following two difficult problems:

[0032] Figure 1The results of the experiment on the cutting effect of luncheon meat slices 1 to 9 of the present invention are shown in FIG. (the order of 1 to 9 is from left to right and from top to bottom);
[0033] Figure 2 These are the experimental results of the marinade effect of the luncheon meat slices of Examples 10-11 of the present invention (left Figure 10, right Figure 11). DETAILED DESCRIPTION
[0034] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" or "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.
[0035] In order to solve the technical problems in the prior art that the meshing effect of large chunks of meat is unevenly distributed and the luncheon meat tissue is soft and has poor elasticity, the applicant has conducted a large number of experiments. The soy protein isolate and phosphate of the present invention adopt a specific tumbling time test design, which can improve the elasticity, hardness and chewiness of meat products, while also achieving a uniform meshing effect of large chunks of meat.
[0036] In addition, the shelf life temperature acceleration test of the pilot qualified products showed that the pilot qualified products can maintain good sensory properties within 19 months, and no water or oil separation occurs; the sodium nitrite content is close to the level of sliced luncheon meat, the residual oxygen content is small and remains stable within 25 months; the commercial sterility is normal, and the total colony count is not detected. This shows that the use of alternative strains to produce luncheon meat products can achieve the same sodium nitrite level of preservation effect, ensuring normal microbial indicators within 24 months.

[0047] Using the same recipe and the same tumbling equipment, different tumbling schemes were tested. The minced meat was made into products according to the process flow, and then the product texture data was measured using a texture analyzer.
[0048] Tumbling solution:
[0049] Solution 1: Three times of forward rotation for 10 minutes, followed by 1 minute of forward rotation each time, and finally 10 minutes of reverse rotation, with a tilt angle of -2°
[0050] Solution 2: Three times of forward rotation for 10 minutes, followed by 2 minutes of reverse rotation each time
[0051] Solution 3: Four times of forward rotation for 10 minutes, with three times of reverse rotation for 1 minute in between
[0052] Solution 4: Four times of forward rotation for 10 minutes, with three intervals of reverse rotation for 2 minutes.
[0053] The experimental results are as follows:
[0054]
[0055] Through the above experimental data and Figure 1 , Figure 2It can be seen that phosphate and SPI have a good synergistic mechanism: phosphate promotes the dissolution of myosin, provides more cross-linking sites for SPI, and forms a dense gel network. SPI enhances the water retention capacity of phosphate through hydrophobic interaction and reduces the damage to the structure caused by high-temperature sterilization. Therefore, it can solve the technical problems of uneven distribution of the flower effect of large meat pieces and poor elasticity of luncheon meat tissue in the prior art. At the same time, by coordinating a specific rolling and kneading scheme, the quality of the product is improved.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
