How to test the hardness of sugar cubes?
The testing method and standard procedure for cube sugar hardness are as follows:
1. Testing Standard Basis
Cube sugar hardness testing primarily complies with QB/T 5011-2016 "Test Methods for Cube Sugar", which specifies the detailed procedures and technical requirements for hardness determination.
2. Testing Equipment and Parameters
Instrument Type: Dedicated cube sugar hardness tester (e.g., models such as DeTian, HP620C).
Measurement Range: Typically 0~200 N (or 0~20 kgf).
Accuracy Requirements: Indication accuracy ≤±1%, resolution 0.01 N.
Testing Speed: 1 mm/s (adjustable range 0~1.3 mm/s).
3. Operational Procedure
Sample Preparation: Select intact cube sugar samples, ensuring no surface damage.
Instrument Calibration: Calibrate the sensor and loading speed according to standard requirements after startup.
Testing Execution:
Place the cube sugar on the test platform and apply pressure using a universal head or dedicated probe.
Load uniformly until the cube sugar fractures, recording the maximum pressure value (i.e., hardness value).
Data Output: The instrument automatically calculates and displays results, supporting printing or data export.
4. Precautions
Environmental Control: Testing must be conducted under constant temperature and humidity conditions to avoid moisture absorption affecting results.
Repeated Testing: It is recommended to perform 3 tests per sample group and average the values to improve accuracy.
Equipment Maintenance: Regularly verify sensor accuracy to prevent probe wear.
5. Extended Applications
Similar equipment can also be used for hardness testing of other sugar types, such as fondant sugar or filled sugar, by replacing probes to enable multifunctional testing.
