The invention specifically relates to a method for estimating in-vitro detoxification effect of a mycotoxin detoxification agent by using liquid chromatography, belonging to the technical field of biological detection. The method comprises the following steps: (1) early stage preparation: I, drafting of a standard curve of mycotoxin; II, preparation of a sample of the detoxification agent; and III, acquisition of a reaction medium; (2) detoxification: I, evaluation of in-vitro adsorption detoxification; and II, evaluation of simulated in-vivo adsorption detoxification; and (3) liquid chromatographic detection. The method for estimating in-vitro detoxification effect of the mycotoxin detoxification agent by using liquid chromatography can simulate gastrointestinal environments, adopts supernatant of chyme in the alimentary canal of an animal as a reaction medium, completely reproduce the gastrointestinal environment in the animal and more authentically evaluate the adsorption effect of an adsorbent.

The invention particularly discloses a colloidal gold card reader for detecting mycotoxins in livestock farms. The colloidal gold card reader comprises a colloidal gold test paper card reading cavity and a colloidal gold test paper image collecting device, wherein the image collecting device comprises a microprocessor, the microprocessor comprises a communication module, an image sensor, a cold light source and a display system, and the microprocessor is connected and communicated with an intelligent terminal through the communication module; mycotoxin colloidal gold test paper corresponding to built-in programs of the microprocessor is required to be placed in the colloidal gold test paper card reading cavity. According to the colloidal gold card reader, color developing results of the colloidal gold test paper are collected by the image sensor, so that detection result errors caused by errors produced by manual evaluation can be avoided. The detection results of the same batch are processed by one evaluation system and are calculated according to a preset internal standard curve, so that stability of the detection results is facilitated.
