Embodiment Construction

[0018] Such as figure 1 As shown, the present invention is a rapid food allergen tester, which includes a biosensor module for sensing changes in the biological response of allergens, and a high-frequency sensor for converting the changes in the biological responses sensed by the biosensor module into electrical signals. A signal generator and a signal acquisition processor for analyzing and processing the electric signal, and storing and displaying the processed data.

[0019] The signal acquisition processor includes an embedded computer, a communication module, a digital display module, a test button module and a power supply module; the embedded computer is connected to the communication module, the digital display module, the test button module and the power supply module respectively.

[0020] The communication module is used for communication and data storage, and adopts RS232 interface.

[0021] The digital display module is used to display test results, and a CRT or ...

Abstract

The invention relates to a rapid food allergen tester, which comprises a biosensor module, a high-frequency signal generator and a signal acquisition processor. The signal acquisition processor comprises am embedded computer, a communication module, a digital display module, a testing key module and a power supply module, wherein the embedded computer is respectively connected with the communication module, the digital display module, the testing key module and the power supply module; the communication module is used for communication and data storage; the digital display module is used for displaying testing results; the testing key module is used for selecting testing keys; and the power supply module is used for supplying power. Since the rapid food allergen tester is formed by the biosensor module, the high-frequency signal generator and the signal acquisition processor, the structure is simple; and since the powerful digital signal processing function of the embedded computer isused for processing and displaying signals generated by the biosensor and the high-frequency signal generator, the online measurement is realized and the high measurement accuracy is ensured.

Description

(1) Technical field [0001] The invention relates to the field of food safety, in particular to a rapid food allergen tester. (2) Background technology [0002] In recent years, more and more case reports related to food allergy have been reported, and the incidence of food allergy is continuing to increase. Due to the differences in genetic factors and eating habits of different countries and ethnic groups, the order of allergens in food may be different, but in general, the foods that cause high frequency of allergies mainly include: peanuts and their products; eggs and Egg products; milk and dairy products (including yogurt, cheese, casein lactose, etc.); soybeans and other beans and various soy products; wheat, barley, oats, etc. and grain products; fish and their products; crustaceans and Its products; fruits, etc. As a public health issue, food allergy has attracted more and more attention as a food safety issue. For the health of consumers, on the one hand, many dev...
