Introduction
Technical background and industry significance of the standard
As food safety supervision becomes stricter, the need for standardization of borax test paper as a rapid on-site testing tool has become increasingly prominent. This standard was jointly drafted by 7 testing institutions, filling the gap in technical specifications for curcumin colorimetry in the field of rapid testing.
Analysis of core performance indicators
| Indicator | Required value | Test method | Industry comparison |
|---|---|---|---|
| Detection limit | ≤50mg/kg | Quality control sample gradient test | 10 times higher than ELISA method |
| Sensitivity | ≥99% | 100 times positive quality control | Better than colloidal gold method |
| False positive rate | ≤5% | 100 times of negative quality control | Equivalent to HPLC |
Detailed explanation of key technical principles
Curcumin colorimetric method uses the characteristic of generating red complex under acidic conditions, and its reaction equation is:
Na₂B₄O₇·10H₂O + 2H⁺ → 4H₃BO₃ + 2Na⁺ + 5H₂O
Actual application cases show that in the detection of cold noodle samples, the color development time of the test paper should be controlled at 30±5 seconds, and the ambient temperature should be maintained at 15-30℃.
Implementation recommendations and precautions
- 4-10℃ cold chain is required for transportation and storage
- 25℃ environmental balance is required before testing
- Batch-to-batch repeatability verification is recommended for each batch
The standard implementation data shows that in the 45-day stability test, the qualified rate of products of companies such as Beijing Puzan reached 98.7%.
