Meaning of measurement
Measuring the viscosity of starch can help manufacturers control the quality and use of starch, so as to achieve the following purposes:
Determining the degree of solubility of starch: The viscosity of starch can reflect the degree of solubility of starch. Measuring the viscosity of starch can help manufacturers determine the degree of solubility and quality of starch, so as to ensure that the starch can achieve the desired binding effect and stability.
Control the amount of starch used: The viscosity of starch can also affect its amount and effect. Measuring the viscosity of starch can help producers determine the amount and ratio of starch used in order to maximize production efficiency and product quality.
Optimizing the production process: Measuring the viscosity of starch can help producers optimize the production process of starch to improve production efficiency and product quality.
Product development: Measuring the viscosity of starch can help producers develop new starch products, improve the performance and function of starch, and ultimately meet market demand.
Measuring the viscosity of starch is an important means to ensure the quality and performance of starch products. It can help producers control starch quality, improve production efficiency, develop new products, and ultimately meet customer needs.
Measurement steps
Rotational viscometer is also one of the commonly used instruments in the detection of starch viscosity. The principle is to determine the viscosity of the solution by measuring the resistance of the starch solution to flow on the surface of a rotating cylinder.
The following are the steps for starch viscosity detection using a Rotational Viscometer:
Sample preparation: Stir the starch sample to be tested evenly and pour it into the sample cell of the Rotational Viscometer.
Adjust the temperature: adjust the temperature of the Rotational Viscometer according to the specifications of the starch.
Adjust the rotation speed: select the appropriate rotation speed according to the viscosity range of the starch solution.
Start the test : Start the Rotational Viscometer and wait a few minutes until a stable reading appears.
Document the results: Record the reading on the Rotational Viscometer and compare to the starch specification.
NBCHAO reminds you: Before performing the Rotational Viscometer test, the instrument needs to be calibrated to ensure the accuracy of the test results. In addition, when using a Rotational Viscometer for testing, it is necessary to strictly follow the instructions of the instrument to avoid damage to the instrument or inaccurate test results. For starch samples, since the viscosity of the starch solution is related to its concentration, it needs to be diluted to an appropriate concentration before testing. In addition, for high-viscosity starch solution samples, it is recommended to dilute it to an appropriate concentration before testing, so that the test results will be more accurate.
