Description

Technical Field

[0001] The invention relates to the technical field of food processing, in particular to hot pot shrimp paste and a processing method thereof. Background Art

[0002] In the fast-paced modern life, hot pot, as a dining form that combines deliciousness and social interaction, is deeply loved by consumers. As a common ingredient in hot pot, shrimp paste has become a star product on the hot pot menu with its fresh taste, rich nutritional value and diverse cooking methods. However, there are some problems that need to be solved in the practical application of traditional shrimp paste preparation technology.

[0003] The traditional shrimp paste preparation process often relies on simple physical mixing and stirring. Although it can produce basic shrimp paste products, in the high-temperature hot pot environment, the shrimp paste is prone to looseness and turbidity in the soup, which seriously affects the eating experience and the overall flavor of the hot pot. The root of this problem is that the excipients used in the traditional process (such as ordinary modified starch) are not stable enough at high temperatures, and cannot effectively maintain the structural integrity of the shrimp paste and the clarity of the soup, which greatly affects the consumer's eating experience. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a hot pot shrimp paste and a processing method thereof.

[0005] In a first aspect, the present invention provides a hot pot shrimp paste, which comprises the following raw materials by weight:

[0006] 90-110 parts of shrimp, 5-10 parts of modified starch, 15-20 parts of egg white, 1.5-2.8 parts of seasoning and 10-15 parts of water;

[0007] The modified starch is obtained by sequentially subjecting the starch to freeze-thaw cycle treatment and variable frequency ultrasonic treatment.

[0008] Furthermore, the hot pot shrimp paste comprises the following raw materials in parts by weight:

[0009] 100 parts of shrimp, 8 parts of modified starch, 17 parts of egg white, 2.2 parts of seasoning and 13 parts of water.

[0011] The starch raw material is subjected to freeze-thaw cycle treatment to obtain a first modified starch;

[0012] Adding the first modified starch into water and stirring to obtain a first modified starch liquid;

[0013] The first modified starch liquid is subjected to variable frequency ultrasonic treatment and then dried to obtain the modified starch.

[0014] Furthermore, the working condition parameters of the freeze-thaw cycle treatment include: freezing temperature of -30 to -20°C, freezing time of 30 to 60 minutes, thawing temperature of 35 to 45°C, thawing time of 3 to 5 hours, and number of cycle treatments of 4 to 8 times.

[0015] Furthermore, in terms of weight percentage, the solid content of the first modified starch solution is 10-20wt%.

[0016] Furthermore, the first modified starch liquid is subjected to variable frequency ultrasonic treatment and then dried to obtain the modified starch, which comprises the following process:

[0017] The first modified starch liquid is subjected to ultrasonic treatment for 20 to 30 minutes under the conditions of 20 kHz ultrasonic frequency, 500 to 600 W ultrasonic power and 60 kHz ultrasonic frequency, 200 to 300 W ultrasonic power, respectively, to obtain a second modified starch liquid;

[0018] The second modified starch liquid is dried to obtain the modified starch.

[0019] Furthermore, the drying includes the following process: drying at a temperature of 45-50° C., and spray drying when the second modified starch liquid has a solid content of 50-60wt%.

[0020] Furthermore, the seasoning is composed of salt and monosodium glutamate in a weight ratio of (1-1.5):(0.1-0.5).

[0021] In a second aspect, the present invention provides a method for processing hot pot shrimp paste according to any one of the first aspects, the processing method comprising the following steps:

[0022] The shrimps are crushed and beaten to obtain minced meat;

[0023] The modified starch, egg white, seasoning and water are stirred and mixed, and then the minced meat is added and stirred and mixed to obtain the hot pot shrimp paste.

[0024] Furthermore, the processing method also includes: placing the hot pot shrimp slips in an environment of -25 to -20°C for frozen preservation.

[0025] The above technical solution provided by the embodiment of the present invention has at least the following advantages compared with the prior art:

[0026] The embodiment of the present invention provides a hot pot shrimp paste and a processing method thereof. Based on the existing shrimp paste preparation process, the present invention uses modified starch obtained by freeze-thaw cycle treatment combined with variable frequency ultrasonic treatment as an excipient, thereby improving the high temperature stability of the obtained shrimp paste, and can effectively avoid the existing shrimp paste from being loose and having turbid soup during the hot pot cooking process. The overall quality and eating experience of the shrimp paste are greatly improved, and many deficiencies in the traditional shrimp paste preparation technology are made up. Specifically:

[0027] 1. Processing principle of modified starch

[0028] Freeze-thaw cycle treatment:

[0029] Freeze-thaw cycle is a physical treatment method that alternates between low-temperature freezing and room-temperature thawing. During this process, the modified starch molecules will undergo crystallization during freezing and decrystallization during thawing, resulting in subtle changes in the intermolecular structure, such as rearrangement of hydrogen bonds and local rearrangement of molecular chains.

[0030] This treatment helps break up the original crystalline structure of the modified starch, making it easier to mix with other ingredients and showing better dispersibility and stability in subsequent processing.

[0031] Frequency conversion ultrasonic treatment:

[0032] Variable frequency ultrasonic technology uses the physical effects of ultrasound in liquids, such as cavitation effect, mechanical vibration, and micro-jet, to shear and impact modified starch molecules at the microscopic level.

[0033] This treatment can further destroy the surface structure of modified starch particles and promote the depolymerization and dispersion of modified starch molecules, thereby increasing their specific surface area and reactivity.

[0034] At the same time, variable frequency ultrasound can also promote the cross-linking effect between modified starch molecules, forming a tighter network structure and improving the high temperature resistance and stability of modified starch.

[0035] 2. Synergistic mechanism of modified starch in shrimp slip

[0036] Excipient and stabilizing effect:

[0037] The modified starch, which has been subjected to freeze-thaw cycles and variable frequency ultrasonic treatment, has excellent shaping ability and high temperature stability. During the preparation of shrimp slips, it can be evenly wrapped around the shrimp meat particles to form a stable protective film.

[0038] This protective film can effectively resist the shrinkage and deformation of shrimp meat in a high-temperature hot pot environment, maintain the structural integrity and shape stability of the shrimp meat, and avoid the occurrence of looseness.

[0039] Improve the taste and keep the soup clear:

[0040] The addition of modified starch also makes the shrimp paste more tender and delicate in taste. The network structure formed by it can lock the moisture and umami substances in the shrimp meat and reduce the loss during the cooking process.

[0041] At the same time, due to the good high-temperature stability of the modified starch, it is not easy to dissolve or gelatinize in the hot pot, thus avoiding the turbidity of the soup and maintaining the clarity and overall flavor of the hot pot.

[0042] Synergy with other ingredients:

[0043] As the main ingredient of shrimp paste, shrimp provides rich protein and umami substances. The addition of modified starch not only enhances the structural stability of shrimp paste, but also makes the umami flavor of shrimp more evenly distributed in the shrimp paste through its good dispersibility and encapsulation.

[0044] Egg white acts as a natural binder and tenderizer, working together with modified starch to further enhance the tenderness and taste of shrimp paste.

[0045] Seasonings and water are added precisely according to the recipe and blended with ingredients such as modified starch and shrimp to create a hot pot shrimp paste product with unique flavor and rich taste.

[0046] In summary, the present invention uses the modified starch obtained by freeze-thaw cycle treatment combined with variable frequency ultrasonic treatment as an excipient, which not only improves the high temperature stability and overall quality of shrimp paste, but also achieves a comprehensive improvement in taste, flavor and appearance through the synergistic mechanism between the raw materials. This innovative technology provides a new idea and method for the processing of hot pot shrimp paste, and has broad market application prospects. DETAILED DESCRIPTION
