[0002] In the traditional tofu production process, Physalis is a key coagulant and flavor regulator, and its concentration has a significant impact on the quality, taste, and coagulation effect of tofu. However, the current methods for determining the concentration of Physalis lack accuracy, convenience, and stability, and most of them rely on empirical judgment or simple rough measurements, which cannot meet the strict requirements of modern large-scale production for the consistency of tofu quality. Therefore, it is necessary to develop an accurate, efficient, and easy-to-operate device and method for determining the concentration of Physalis to improve the quality control level and industrial production efficiency of tofu production.

[0006] Furthermore, limit seats 101 are provided at both ends of the scale plate 1.

[0007] Furthermore, a test paper slot 301 is provided inside the test paper installation box 3 .

[0008] Furthermore, a pull ring 501 is provided at the end of the pull rod 5 .

[0009] The determination method comprises the following steps: 1. During the production process of dried bean curd, when determining the concentration of sour pulp, a pH test paper is installed inside a test paper installation box 3, and a determination device is inserted into the sour pulp; 2.

[0021] See also Figure 1-4 As shown, the technical solution adopted in this specific embodiment is: the device for determining the concentration of tofu in the production process of dried bean curd comprises a scale plate 1, a mounting platform 2, a test paper mounting box 3, a PH test paper 4, a pull rod 5, a slide groove 6, a scale mark 7, a through hole 8, a limit seat 101, a test paper slot 301, and a pull ring 501; a slide groove 6 is provided in the middle of the scale plate 1, and the lower part of the mounting platform 2 is slidably connected with the slide groove 6 by interference fit, a test paper mounting box 3 is provided on the mounting platform 2, and a plurality of through holes 8 are provided around the test paper mounting box 3, the PH test paper 4 is inserted into the test paper mounting box 3 and fixedly installed, a fixed pull rod 5 is provided at the upper end of the mounting platform 2, and scale marks 7 are provided on the surface of the scale plate 1 on both sides of the slide groove 6.

[0022] Furthermore, the scale plate 1, the mounting platform 2, the test paper mounting box 3, and the pull rod 5 are all made of food-grade plastic materials, which can ensure that the pH value of the Physalis will not be affected during the measurement of the Physalis.

[0023] Furthermore, the two ends of the scale plate 1 are provided with limit seats 101, which can limit the installation platform 2 installed in the slide groove 6 to prevent the installation platform 2 from sliding out and falling.

[0024] Furthermore, a test paper slot 301 is provided inside the test paper installation box 3 , and the size of the test paper slot 301 matches the size of the PH test paper 4 , so that the PH test paper 4 can be replaced immediately.

[0025] Furthermore, a pull ring 501 is provided at the end of the pull rod 5. When using the measuring device of the present invention, the mounting platform 2 can be pulled by the pull ring 501, and the measuring position of the mounting platform 2 can be adjusted according to the scale mark 7 to accurately measure the concentration of key components of the nightshade at different depths.

[0026] The determination method comprises the following steps: 1. During the production process of dried bean curd, when determining the concentration of sour pulp, a pH test paper is installed inside a test paper installation box 3, and a determination device is inserted into the sour pulp; 2. According to the sour pulp depth to be measured, the pull rod 501 is pulled to adjust the appropriate position of the mounting platform according to the scale mark 7; 3. The mounting platform 2 is placed at the designated position of the sour pulp, and the sour pulp enters through the through hole 8 on the side of the test paper installation box 3 and contacts and reacts with the pH test paper 4; 4. The pH value in the sour pulp is determined by the display result of the pH test paper 4, and an acid-base neutralizer is added or the acid-base solubility is diluted according to production needs to reach the pH value required by the production process.

[0027] When the acidity is too strong (pH value is too low):

[0028] If the acidity of the plant is too strong, its pH value needs to be increased, that is, the acidity needs to be reduced. You can add an appropriate amount of alkaline substances to neutralize the excess acid. Common alkaline substances include baking soda (sodium bicarbonate, NaHCO3).

[0029] Assuming that the pH value of Physalis is 3, its pH value needs to be raised to about 4-5. You can first add a small amount of experimental addition. For example, add 0.1 grams of baking soda to every 100 milliliters of Physalis, stir thoroughly, and then test the pH value again with pH test paper. According to the test results, gradually adjust the amount of addition until the desired pH range is reached. This is because baking soda reacts chemically with the acid in Physalis. For example, the chemical equation for the reaction with lactic acid is C3H6O3+NaHCO3→C3H5O3Na+H2O+CO2↑, which increases the pH value by consuming the acid.

[0030] When the acidity is too weak (pH value is too high):

[0031] When the acidity of Physalis is too weak, the pH value needs to be lowered, that is, the acidity needs to be increased. You can add an appropriate amount of acidic substances, such as edible vinegar (the main component is acetic acid, CH3COOH).

[0032] For example, if the pH value of Physalis is 6 and you want to lower it to 4-5, you can add 0.5 ml of edible vinegar to every 100 ml of Physalis, stir well and test with pH test paper. This is because the added acetic acid will ionize hydrogen ions. Increase the hydrogen ion concentration in the solution, thereby lowering the pH value. Again, the amount added should be gradually adjusted based on the test results.

[0033] Things to note during adjustment:

[0034] When adding acid-base regulators, pay attention to fully stirring the acid paste to ensure that the regulator is evenly distributed so that the pH value can be accurately adjusted throughout the acid paste system.

[0035] After adding each regulator, wait for a while to allow the chemical reaction to fully proceed before testing the pH value. Generally, 1-2 minutes is enough, but if some regulators with slower reaction speed are used or the sophora japonica system is more complicated, the waiting time may need to be appropriately extended.

[0036] At the same time, other effects of the regulator on the flavor of the nightshade and subsequent tofu production should be considered. For example, adding too much baking soda may make the nightshade have an alkaline taste, affecting the flavor of the tofu; adding too much vinegar may make the acidity of the nightshade not meet the requirements of traditional craftsmanship, and will also have an adverse effect on the taste of the tofu. Therefore, the adjustment process should be cautious to ensure that the nightshade is at the appropriate pH, which can not only ensure the quality of the tofu, but also maintain its traditional flavor.

[0037] The above description is only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
