Abstract
A food safety detection device includes a xylem fiber substrate. A sampling portion and a reaction portion are disposed on the xylem fiber substrate. The reaction portion includes at least one chemical reagent. The sampling portion absorbs a test sample. The test sample moves on the xylem fiber substrate to the reaction portion and reacts with the chemical reagent. The present invention further provides a manufacturing method. The present invention is advantageous for easy operation, safety and rapid analysis.
