Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of food processing equipment, in particular to a device for detecting the foaming and emulsification of protein. Background Art
[0002] The foaming and emulsifying properties of protein are important research topics in food science, mainly involving the functional properties of protein. The following are some common testing methods:
[0003] Protein foaming test:
[0004] Prepare a protein solution of a certain concentration, such as a 1% egg white protein solution.
[0005] Beat in a high-speed disperser at a certain speed (such as 8000r / min) for a certain time (such as 2min).
[0006] Record the liquid and foam height before and after whipping, and calculate the foaming capacity (formula: ).
[0007] Protein emulsification test:
[0008] Take a certain amount of pasteurized protein solution and dilute it with buffer to a solution of a certain concentration.
[0009] Add oil substances in a certain ratio (such as 3:1), and then beat in a high-speed disperser.
[0010] Take a certain amount of the bottom emulsion and add it to a certain concentration of SDS solution.
[0011] The absorbance (A500nm) is measured at a specific wavelength (such as 500nm) to evaluate the emulsification property.
[0012] Determination of Emulsification Activity Index (EAI):
[0013] A protein solution of a certain concentration is mixed with oil substances to prepare an emulsion.
[0014] Take a certain amount of emulsion and add it to SDS solution of a certain concentration.
[0015] Measure its absorbance (A500nm) at a specific wavelength (such as 500nm) and calculate EAI based on the absorbance value and the dilution factor of the emulsion.
[0016] When measuring the emulsification and foaming properties of protein solutions, traditional high-speed emulsifying shearing machines use rotating nuts to clamp various brackets on the bracket columns. The height of the bracket is usually adjusted manually. The bracket adjustment scale cannot be accurately controlled before each test, and the measuring tube needs to be held in the measurement process. When shearing the solution at high speed, a vortex is formed at the center. The liquid level at the center is low and the surrounding liquid level is high. It is difficult to ensure that the emulsifying head is in the center of the measuring tube during the measurement process. In addition, the depth of the stirring emulsifying head inserted into the liquid surface will also affect the emulsification effect, resulting in large errors in the measurement results between batches. Utility Model Content
[0017] In order to solve the problem that the stirring emulsification head cannot be ensured to be in the center of the measuring tube when the solution is sheared at a high speed, which leads to large errors in the measurement results, the utility model provides a device for detecting the foaming and emulsification of protein.
[0018] The utility model is realized by the following technical solutions:
[0019] A device for detecting the foaming and emulsifying properties of protein, comprising a base, a height bracket vertically arranged on the base, a scale mark and grooves evenly distributed on the height bracket;
[0020] A measuring cylinder is provided on one side of the height bracket; a stirring bracket is provided above the measuring cylinder, a stirring emulsification head is rotatably provided at the bottom end of the stirring bracket, and a driving motor capable of driving the stirring emulsification head is provided at the top end of the stirring bracket;
[0021] The stirring bracket is connected to a horizontally extending transverse bracket, and the transverse bracket is provided with a scale mark and two grooves evenly distributed on the transverse bracket;
[0022] The transverse support is installed on the height support through a locking assembly.
[0023] By adjusting the fixed position of the transverse bracket on the height bracket, the stirring emulsifying head can be adjusted to the center position of the measuring cylinder, and the depth adjustment in the liquid in the measuring cylinder can be achieved, thereby reducing the error of the measurement result.
[0024] A further improvement of the utility model is that the above-mentioned transverse bracket moves along a fixed straight line track in the horizontal direction, which helps to reduce interference factors in the adjustment process.
[0025] A further improvement of the utility model is that the middle and lower sections of the height bracket are connected with an auxiliary guide piece sleeved on the stirring bracket, and the guiding direction of the stirring bracket by the auxiliary guide piece is in the same vertical plane as the moving track of the horizontal bracket, which helps to prevent the shaking of the stirring bracket during the position adjustment process.
[0026] A further improvement of the utility model is that the auxiliary guide member is provided with a guide assembly capable of fixing the stirring bracket, which helps to increase the stability strength of the stirring bracket.
[0027] A further improvement of the utility model is that the measuring cylinder is connected with a measuring fixing bracket extending in a horizontal plane, and the measuring fixing bracket is connected to the height bracket through a locking assembly 3 to achieve the stability of the measuring cylinder on the base.
[0028] A further improvement of the utility model is that the measuring fixed bracket is provided with a scale mark and three grooves evenly distributed on the measuring fixed bracket, which cooperate with the adjustable structure of the horizontal bracket to help improve the adjustment accuracy.
[0029] It can be seen from the above technical scheme that the beneficial effects of the utility model are: adjusting the fixed position of the horizontal bracket on the height bracket to adjust the stirring emulsification head to the center position of the measuring cylinder, and being able to adjust the depth in the liquid in the measuring cylinder, thereby reducing the error of the measurement result.
