Method for extracting pesticide residues in fruits and vegetables through molecular distillation

The invention discloses a method for extracting pesticide residues in fruits and vegetables through molecular distillation in the technical field of pesticide residue determination. The method comprises the following steps: S1, crushing a fruit and vegetable sample; the method comprises the following steps: S1-1, peeling a fruit and vegetable sample in a crushing device, retaining fruit and vegetable peels, and extruding the fruit and vegetable peels; s1-2, performing solid-liquid separation on the extruded fruit and vegetable peels to obtain fruit and vegetable juice and fruit and vegetable peels, and soaking the fruit and vegetable peels subjected to solid-liquid separation in grease; s2, extracting an extracting solution by a molecular distillation method; s3, extracting a pesticide residual liquid by using an organic solvent, separating banana peel from banana pulp by using a crushing device because most of pesticides remain on the peel, then extruding the banana peel to obtain banana juice and extruded p
