The invention discloses a method for identifying organic 
hot peppers based on 
stable isotope ratio, and belongs to the technical field of trueness identification of organic foods. The method comprises the following steps of: comparing the 
delta 15N values of true organic 
hot peppers and hot pepper samples to be measured, wherein if no 
significant difference exists, the hot pepper samples to be measured are indicated to be true organic hot pepper samples, and if the 
significant difference exists, the hot pepper samples to be measured are indicated to probably not be the true organic hot pepper samples; or firstly measuring a large quantity of true organic 
hot peppers, establishing an organic hot pepper N 
isotopic composition characteristics 
database, then detecting whether the 
delta 15N value of the hot pepper samples to be measured is contained in the organic hot pepper N 
isotopic composition characteristics 
database, wherein if so, the hot pepper samples to be measured are organic hot peppers, and if not, the hot pepper samples to be measured are probably not the true organic hot peppers. The method capable of accurately identifying the organic hot peppers, which is disclosed by the invention, is established by utilizing a stable 
isotope mass spectrometry technology, can be used for solving the technical problem of national organic hot peppers on market supervision and is conductive to specifying the market behaviors, protecting the benefits of consumers and legal enterprises and promoting the healthy and orderly development of an organic 
food industry.
