The invention provides a method for identifying different origins of red plum and apricot, and belongs to the technical field of food detection. In this method, the place of origin is respectively Pengyang County (PY-HM), Guyuan Pengbao Town (YZ-PP-HM-Y), Guyuan Nanping Village (YZ-NP-HM-Y); Pengyang, Guyuan The markers of red apricot plum from the county production area are: 2-methyl butanol, n-hexanol, butyl acetate; the markers of red apricot plum from the production area of Pengbao Town, Guyuan are: trans-2-hexene-1-alcohol, 5 ‑Methyl‑2‑furanmethanol, benzaldehyde, n-hexanal, valeraldehyde, phenylacetaldehyde, ethyl hexanoate, butyl acetate; the markers for red apricot plum from Nanping Village, Guyuan are: trans‑2‑hexane En-1-alcohol, 5-methyl-2-furan methanol, benzaldehyde, n-hexanal, valeraldehyde, phenylacetaldehyde, ethyl hexanoate. The method has the advantages of convenient sample pretreatment, simple operation and high accuracy and sensitivity, which can realize rapid and accurate identification of red plum apricots from different origins, and provide a solid theoretical basis for improving the quality of red plum apricots and their counterfeit sales.
Description
technical field [0001] The invention belongs to the technical field of food detection, in particular to a method for identifying different origins of red plum and apricot. Background technique [0002] Red plum apricot (Prunusarmeniaca L.), also known as Xinjiang apricot, originally originated from Xinjiang and is known as "Xinjiang red". It has been cultivated in the mountainous areas of southern Ningxia for more than 30 years, especially in Pengbao Town and Nanyang District, Yuanzhou District, Guyuan City. Ping Village and Pengyang County in Guyuan City have reached a certain scale, providing support for promoting economic development in the southern mountainous areas of Ningxia, getting rid of poverty and becoming rich, and ecological construction. However, red plum apricots are widely distributed, cultivated and grafted with many varieties, complex sources, and different qualities. Therefore, it is necessary to identify the origin of red plum apricots. [0003] At prese...
