This invention belongs to the field of food texture evaluation and functional fit analysis technology, and discloses a method and system for evaluating food chewing fit based on a staged electromyography (EMG) strategy. The method collects surface EMG signals from subjects during food chewing, divides the chewing process into stages, extracts EMG activation strategy characteristics at different chewing stages, and constructs food-chewing function fit evaluation rules based on these staged EMG characteristics, thereby achieving an objective evaluation of the matching relationship between food texture and chewing function.
