Outline
To evaluate commercially available rapid test products for aflatoxin B1 based on the entropy weight method-technique for order preference by similarity to an ideal solution coupling model(EW-TOPSIS).
Rapid test products of different brands for aflatoxin B1 were tested under multi-dimensional conditions involving different application environments, different operators and different food matrices. The 3 indicators, namely sensitivity, false negative rate and false positive rate, were examined. EW-TOPSIS analysis was performed, in which objective weighting through the entropy weight method was employed to eliminate subjective bias, and then the TOPSIS method was combined to calculate the closeness of products to the ideal solution for ranking. The comprehensive performance of 3 brands was systematically evaluated, and ultimately a complete and scientific evaluation system for AFTB1 rapid test products was established.
The weights of sensitivity, false negative rate and false positive rate determined by the entropy weight method were 0.3377, 0.3377 and 0.3247, respectively. The ranking of the 3 brands based on the closeness coefficient was brand A (0.8597)>brand B (0.6136)>brand C (0.4214). A higher closeness coefficient indicated better comprehensive performance; therefore, Brand A was identified as the optimal one, which remained stable under extreme temperatures and with different operators, exhibiting outstanding performance in accuracy, specificity, and applicability, followed by brand B and brand C in descending order.
This model is applicable for the comprehensive evaluation of rapid test products of various brands and matrices, providing a basis for product selection at the grassroots level and quality control by regulatory authorities, while also offering a novel approach for the evaluation of rapid test products and promoting the standardized application of rapid test technology in the field of food safety.
