Problems solved by technology

[0003] 1. For fruits with a lot of pulp, such as apples, pears, peaches, etc., the detection part is too single, and it is impossible to do corresponding fine detection of the pesticide residues in each part of the fruit;
[0004] 2. In the actual detection process, the processing of the detection object is too simple to form an accurate comparison of a system, so there are large errors in the detection results, which reduces the overall detection accuracy

Embodiment 1

[0027] The invention provides a technical solution: a method for accurately detecting pesticide residues in agricultural products. The agricultural products to be inspected are apples that have been sprayed on the fruit surface for a week, and there is no rainfall within a week. The method for pesticide residues in apples specifically includes the following steps:

[0028] Step 1: Clean the surface of the peel. Put the apples in an ultrasonic cleaning tank, and add warm water at 25°C to the tank so that the water surface is submerged by 1 cm above the surface of the apples. After soaking for 5 minutes, use ultrasonic cleaning for 3 minutes, then take out the fruit and wash it. Dry the fruit surface, and take out the cleaning solution for later use. Pay attention to shortening the fruit stem of the apple before cleaning, so as to avoid damage to the peel due to the bending of the too long fruit stem and the adhesion of the peel, which will affect the test results. When wiping the...

Embodiment 2

[0038] The invention provides a technical solution: a method for accurately detecting pesticide residues in agricultural products. The agricultural products to be inspected are pears that have been sprayed on the fruit surface for one week, and there has been no rainfall within a week. The method for pesticide residues in pears specifically includes the following steps:

[0039] Step 1: Clean the surface of the peel. Put the pears in an ultrasonic cleaning tank, and add warm water at 22°C to the tank so that the water surface is 1 cm above the surface of the pears. After soaking for 4 minutes, use ultrasonic cleaning for 2 minutes, then take out the fruit and wash it. Dry the fruit surface, and take out the cleaning solution for later use. Pay attention to shortening the fruit stem of the pear before cleaning, so as to avoid damage to the peel due to the bending of the too long fruit stem and the adhesion of the peel, which will affect the test results. When wiping the fruit, E...

Embodiment 3

[0049] The invention provides a technical solution: a method for accurately detecting pesticide residues in agricultural products. The agricultural products to be inspected are peaches that have been sprayed on the fruit surface for one week, and there has been no rainfall within a week. The method for pesticide residues in peaches specifically includes the following steps:

[0050] Step 1: Clean the surface of the peel. Put the peaches into the ultrasonic cleaning tank, and add warm water at 23°C to the tank so that the water surface is submerged by 1 cm above the surface of the peaches. After soaking for 6 minutes, use ultrasonic cleaning for 4 minutes, then take out the fruit and wash it. Dry the fruit surface, and take out the cleaning solution for later use. Pay attention to shortening the fruit stalk of the peach before cleaning, so as to avoid damage to the peel due to the bending of the too long fruit stalk and the adhesion of the peel, which will affect the test results...

Abstract

The invention relates to the technical field of agricultural product pesticide residue detection, and particularly discloses an agricultural product pesticide residue precise detection method. The agricultural product pesticide residue precise detection method comprises the steps of: cleaning surfaces of pericarp; concentrating a cleaning solution; separating carpopodium of a fruit, separating pericarp at the upper and lower ends of the fruit, and separating pericarp and pulp in the middles of the fruit; preparing a stock solution of a to-be-detected sample; preparing reagents including a buffer solution, a substrate solution, a chromogenic solution and an enzyme solution; and detecting a control sample and the sample. According to the agricultural product pesticide residue precise detection method disclosed by the invention, the upper, middle, lower, inner and outer parts of the fruit are finely detected and divided, so that the fine degree of pesticide residue detection of each partof the whole fruit is improved; and each part of the fruit is subjected to independent refining treatment, and the whole detection result can form systematic comparison, so that the detection error isreduced, and the detection precision is improved.

Description

technical field [0001] The invention relates to the technical field of pesticide residue detection in agricultural products, in particular to an accurate detection method for pesticide residues in agricultural products. Background technique [0002] The pesticide residue content of agricultural products is an important indicator for testing the quality of agricultural products. If the pesticide residues in agricultural products exceed the standard, it will seriously affect the food safety of consumers. There are strict standards, and research on how to reduce pesticide residues in agricultural products has become an important scientific research topic, and the detection of pesticide residues in agricultural products has become an important inspection basis for improving the quality of agricultural products. The existing technology for pesticide residues in agricultural products There are many detection methods, which can be roughly divided into biochemical detection methods ...
