The invention relates to the field of pepper
processing and specifically discloses a method for purifying natural
capsaicin. The method comprises the following steps: decomposing the pepper into three parts, including
embryo tissues, peels and pepper seeds; respectively smashing the three parts; adding a corresponding amount of
cellulase into the smashed tissues; stirring and mixing at different rotating speeds and for different stirring durations; accelerating the damage to cells; accelerating the separation of
capsaicin; extracting the
capsaicin from the pepper tissues; dissolving the capsaicin in a solution; and then separating capsaicin crystals from the solution, thereby completing the whole capsaicin extracting and purifying processes. According to the scheme, the pepper is divided into three parts and the three parts in different capsaicin contents are respectively processed, so that the separation of the capsaicin as much as possible can be guaranteed.
