Abstract
Description
Technical Field
[0001] The present application relates to the technical field of cream preparation management, and in particular to a method and management system for preparing pure milk fat cream at room temperature. Background Art
[0002] Cream is an important dairy product widely used in food processing and home baking. Due to its high fat content, traditional cream products have high requirements for temperature conditions during storage and transportation, and usually require cold chain transportation and refrigerated storage. This not only increases logistics costs, but also limits the application of cream products in some special scenarios, such as storage at room temperature or in environments with limited transportation conditions.
[0003] Important factors that affect the stability of cream include the particle size distribution of milk fat globules and the ratio of stabilizers. Uneven particle size distribution of milk fat globules or unreasonable ratio of stabilizers may cause milk fat globules to aggregate or separate easily at room temperature, thus changing the texture and quality of the cream. At present, in the process of cream preparation, the existing technology usually adjusts the milk fat particle size distribution and the ratio of stabilizers through experience or repeated experiments, but lacks scientific guidance methods based on particle size distribution. Therefore, existing cream products still face many challenges in storage and transportation at room temperature, especially in extending the shelf life of the product and maintaining the stability of the product texture. There are technical bottlenecks.
[0004] In addition, homogenization, as a key step in cream processing, has an important influence on the particle size distribution of milk fat globules. However, unreasonable setting of homogenization parameters may lead to a mismatch between the particle size distribution of milk fat globules in cream products and the target particle size distribution, thus affecting the stability and storage performance of the product.
[0005] Therefore, there is an urgent need for a scientific method based on particle size distribution to optimize the management of stabilizer ratio and homogenization parameters in the cream preparation process, so as to solve the technical problem that existing cream products cannot be stored and transported at room temperature.

[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0022] Combine the following Figure 1-Figure 3 A method and system for preparing and managing pure cream at room temperature as described in the embodiments of the present application are explained.
[0023] The technical solution of the embodiment of the present application records a method for preparing and managing pure milk fat cream at room temperature, which is intended to solve the problem that the cream prepared in the prior art can often only be stored and transported under refrigeration, and the cream will have problems such as oil-water separation and rancidity under room temperature conditions. Even slight temperature fluctuations will lead to fat enrichment, reduced whipping rate or even inability to whip.
[0024] The preparation method of room temperature pure cream fat cream in a room temperature pure cream fat preparation management method involved in the technical solution of the present application is: 1) Raw material mixing: Place the main ingredients such as cream, skim milk, anhydrous butter and water into a mixing tank, then add the auxiliary ingredients such as stabilizer, and stir until they are completely dissolved or evenly dispersed; 2) Pre-homogenization: transfer the materials in the mixing tank to the homogenization tank, the homogenization pressure is level 2 0-50kgf / cm 2 , first level total pressure 10-50kgf / cm 2 , homogenization temperature 70-80℃; 3) Cooling and temporary storage: The material after pre-homogenization is cooled to 15℃-20℃ by the cooling plate, and the cooled material is transferred to the finished product tank for temporary storage; 4) UHT sterilization: use ultra-high temperature sterilizer (immersion type) for sterilization; 5) Post-homogenization: homogenization pressure level 2 0-50kgf / cm 2 , first level total pressure 50-400kgf / cm 2 , homogenizing temperature 70-80℃.
[0025] The auxiliary ingredients mentioned above include the stabilizer referred to in the embodiments of the present application. In the actual preparation process, sodium carboxymethyl cellulose, hydroxypropyl methyl cellulose or carrageenan is often added as a stabilizer; the preparation of the cream is completed through two homogenization processes of pre-homogenization and post-homogenization.
[0026] The technical solution of the present application aims to improve the ratio of stabilizers in the preparation process of cream and the particle size distribution after secondary homogenization, so that pure milk fat cream can be stored and transported at room temperature and the energy loss of storage and transportation can be reduced.
[0027] The present application document records a method for preparing and managing room temperature pure milk fat cream, which mainly includes: S20: Obtain a first particle size distribution of the cream after secondary homogenization under a first ratio, and calculate a first particle size mean under the first particle size distribution.
[0028] In the above technical solution, the first particle size distribution is obtained by measuring the sample by dynamic light scattering (DLS) after secondary homogenization.
[0029] S40: Determine the first particle size mean μ under the first particle size distribution 1 Is it greater than the preset mean particle size μ under the preset particle size distribution? 0 , wherein the preset particle size distribution is pre-configured; under the preset particle size distribution, room temperature storage and transportation of the prepared cream can be achieved; S42: dividing the part in the first particle size distribution into regions based on the particle size comparison result; Among them, if the first particle size mean under the first particle size distribution m 1 Larger than the preset particle size mean m 0 , then the first particle size distribution and the portion of the preset particle size distribution between the first particle size mean and the maximum value of the preset particle size distribution are divided into regions; The first particle size mean under the first particle size distribution m 1 Not larger than the preset particle size average m 0 , dividing the first particle size distribution and the portion of the preset particle size distribution between the preset particle size mean and the maximum value of the first particle size distribution into regions; S44: Based on the division result, compare the first particle size distribution and the preset particle size distribution in each area.
[0030] S60: adjusting the proportion of the stabilizer and / or the homogenization parameters in the cream based on the comparison result.
[0031] In the above technical scheme, when it is necessary to adjust the stabilizer and / or homogenization parameters, the adjustment is made in the direction of producing strong stability at room temperature, such as increasing the content of the stabilizer, increasing the secondary pressure of the pre-homogenization / post-homogenization, or the total pressure value of the first level.
[0032] It should be noted that, since there is already a corresponding empirical temperature to ensure the quality of cream during the cream preparation process, since temperature is responsible for the influence of cream particle size, and in order to avoid fat oxidation, protein denaturation or Maillard reaction that may cause color changes in the cream preparation due to higher temperatures, the adjustment of homogenization parameters referred to in this application to achieve the purpose of room temperature storage and transportation does not include the adjustment of temperature parameters.
[0033] Among them, in the steps of the above technical solution, the number of area divisions k is expressed as: ; in, m , a and b is a constant; is the relative difference between the first particle size mean and the preset particle size mean; its calculation method is: ; m 1 is the mean value of the first particle size, m 0 is the preset particle size mean.
[0034] In a specific example: ; ; .
[0035] Through the above technical solution, the part between the first particle size mean and the preset particle size distribution maximum value or the part between the preset particle size mean and the preset particle size distribution maximum value is divided into multiple regions, and the first particle size distribution is compared with the preset particle size distribution in each region.
[0036] For example, in a specific example, the first particle size average m 1 =2.6, preset particle size mean m 0 =2.2; now select m =5, a =5, b =1; but ;at this time k =4.
[0037] If the first particle size mean m 1 =2.6, preset particle size mean m 0 =2.2; now select m =8, a =10, b =3; but ;at this time k =14; If the first particle size mean m 1 =2.6, preset particle size mean m 0 =2.2; now select m =6, a =6, b =2; but ;at this time k =8.
[0038] The above constants can be selected according to the accuracy requirements of the specific calculation.
[0039] After the area division is completed, k The first particle size distribution and the preset particle size distribution are compared in each region, specifically in the following way: S441, calculated separately k The magnitude of the first divergence and the second divergence in the region; Among them, for a specific interval [ d i , d i+1 ], the first divergence D 1 The calculation methods are: ; The second divergence in this specific interval D 2 The calculation method is:
[0040] In the calculation of the first divergence and the second divergence above, P ( x ) is the first particle size distribution, Q ( x ) is the preset particle size distribution.
[0041] S442, calculated in k In the region, D 1 > D2 The proportion of regions t .
[0042] S443, based on t Adjust the cream preparation parameters according to the following values: 1) If the first particle size average is greater than the preset particle size average, then Dangruo t ≥0.8, indicating that the first particle size distribution at this time does not meet the room temperature storage and transportation requirements referred to in the embodiment of the present application. In this case, it is necessary to adjust the stabilizer ratio and the homogenization parameters at the same time; specifically, it is necessary to increase the content of the stabilizer in the ingredients, and at the same time increase the secondary pressure and the primary total pressure value in the pre-homogenization and post-homogenization processes; If 0.5≤ t <0.8, indicating that the first particle size distribution does not meet the room temperature storage and transportation requirements of the embodiment of the present application. In this case, the mean parameter needs to be adjusted. Specifically, the secondary pressure and the primary total pressure value in the pre-homogenization process need to be increased; If 0.3≤ t <0.5, indicating that the first particle size distribution does not meet the room temperature storage and transportation requirements of the embodiment of the present application. In this case, the ratio of the stabilizer needs to be adjusted, specifically, the content of the stabilizer needs to be increased; like t <0.3, it means that in this case the first particle size distribution meets the requirements, and there is no need to adjust the ratio of the stabilizer, the pre-homogenization parameters, and the post-homogenization parameters. The prepared product meets the requirements of low-temperature storage and transportation as referred to in this application.
[0043] 2) If the first particle size average is not greater than the preset particle size average: like t ≥0.5, the stabilizer ratio needs to be adjusted. As in the above case, the stabilizer content needs to be increased; like t <0.5, it means that in this case the first particle size distribution meets the requirements, and there is no need to adjust the ratio of the stabilizer and the homogenization parameters. The obtained product meets the requirements of low-temperature storage and transportation as stated in the embodiments of the present application.
[0044] Specifically, in the above technical scheme, when it is necessary to adjust the stabilizer ratio, it is always hoped that a smaller t value can be obtained when calculating the first particle size distribution of the cream prepared based on the adjusted stabilizer ratio. At this time, it is characterized that the cream prepared under this stabilizer ratio meets the low-temperature storage and transportation requirements referred to in the embodiments of the present application.
[0045] Therefore, in a specific example, the content of the stabilizer can be established by r and tThe relationship curve of the values is used to adjust the ratio of the stabilizer when preparing the cream in the embodiment of the present application based on the relationship curve.
[0046] For example, in a specific embodiment of the present application, the content of the stabilizer is r (‰)and t The relationship between the values can be expressed as: .
[0047] For example, in a specific example, when the first particle size distribution mean is greater than the preset particle size mean, the calculated t =0.9, then it is necessary to adjust the ratio of the stabilizer and the homogenization parameters. When adjusting, it is expected that the t value obtained by adjusting the stabilizer ratio is a value not greater than 0.5. According to the t value, a new stabilizer ratio can be obtained, and the stabilizer ratio can be adjusted; and then assisted by the adjustment of the pre-homogenization and post-homogenization parameters, it is possible to obtain a cream product that meets the low-temperature storage and transportation requirements of the embodiment of the present application in this case.
[0048] Another embodiment of the present application also records a room temperature pure milk fat cream preparation management system, including: An acquisition module 110 is used to acquire a first particle size distribution of the cream after secondary homogenization under a first ratio; A storage module 120, used to store a preset particle size distribution and a preset particle size mean under a preset particle size; A calculation module 130 is used to calculate a first particle size mean under the first particle size distribution, and compare the first particle size mean with the preset mean, divide the first particle size distribution and the preset particle size distribution into regions based on the comparison, and compare the first particle size distribution and the preset particle size distribution in each region; the calculation module can also calculate a first divergence and a second divergence in each region, and compare the first divergence with the second divergence; Wherein, when dividing the regions, it is necessary to determine whether the first particle size mean under the first particle size distribution is greater than the preset particle size mean under the preset particle size distribution, wherein the preset particle size distribution is pre-configured; if so, the first particle size distribution and the portion of the preset particle size distribution between the first particle size mean and the maximum value of the preset particle size distribution are divided into regions, and the first particle size distribution and the preset particle size distribution are compared in each region; if not, the first particle size distribution and the portion of the preset particle size distribution between the preset particle size mean and the maximum value of the first particle size distribution are divided into regions, and the first particle size distribution and the preset particle size distribution are compared in each region; The number of region divisions k is expressed as: ; in, m, a and b is a constant; is the relative difference between the first particle size mean and the preset particle size mean; its calculation method is: ; m 1 is the mean value of the first particle size, m 0 is the preset particle size mean; For the interval [ d i , d i+1 ], the first divergence D 1 and the second divergence D 2 The calculation methods are: ; ; in, P ( x ) is the first particle size distribution, Q ( x ) is the preset particle size distribution.
