Outline
To evaluate and analyze the rapid detection products for tropical fruit.
The representative tropical fruits (litchi, banana, mango) were selected as the research objects, and the mainstream colloidal gold rapid detection products for common risk factors were selected. The quality of the products was evaluated and verified by 2 kinds of methods: Laboratory standard blind sample evaluation and actual sample verification. It mainly investigated the false positive rate, false negative rate, product type, brand difference and so on.
A total of 98 rapid detection products participated in the blind sample evaluation with additional standards, with a matching rate of 46.9%; 26 products participated in the actual sample verification, with a matching rate of 42.3%. Among the 16 different batch numbers of the same product that participated in the verification by 2 kinds of methods, 9 results were consistent, accounting for 56.3%. Overall, the matching rate of single-card was higher than that of multi-card, and the false negative rate exceeding 5% was the main reason for the inaccuracy of tropical fruit rapid testing products, which also showed significant brand differences.
The total matching rate of rapid detection products for tropical fruits is relatively low. It is necessary to increase research and development efforts, improve product quality and perfect the product evaluation system. This paper can provide data support and theoretical reference for the optimization, standard formulation and scientific application of rapid testing technology for the quality and safety of tropical fruit.
