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.
