The present invention discloses a noodle mechanical properties detection method and an apparatus therefor. A fixed chunk and a mobile chunk used for clamping noodles are respectively mounted, whereinthe mobile chunk is driven to perform a linear movement by a motor as well as a mechanical deceleration transmission mechanism, the fixed chunk is connected to a force detecting terminal of a force sensor. One end of a cooked noodle is wound at the mobile chunk, the other end of the cooked noodle is wound at the fixed chunk or is clamped between two blades exhibiting a certain angle of the fixed chunk. With extensional motions of the mobile chunk, the force sensor transfers the pull or shear stress signals detected to a data processing system which determines the noodle mechanical properties such as tenacity, intensity and the like, through the pull and shear stress data detected. By translating the pull and shear stress index detected into noodle mechanical property indexes such as tenacity, intensity and the like, reference basis for quality checkup of noodles is provided. The develop of said apparatus utilizes computer technology, sensor technology and digital analysis theory, and the application of such more frontier science and technology lays a foundation for exploring and mastering food mechanical performance index.
