AI Technical Summary

Problems solved by technology

In the control of pests and diseases, some farmers use some highly toxic and high-residue pesticides in order to kill pests and diseases as soon as possible, or use pesticides in large doses exceeding the standard, or rush to pursue greater economic benefits after using pesticides, before the pesticides volatilize and degrade To a certain concentration, picking wolfberry in advance, resulting in excessive pesticide residues

Embodiment 1

[0017] The present invention handles the embodiment of the method for pesticide residue on the surface of wolfberry dried fruit, and its steps are:

[0018] (1) 10KG Ningxia Zhongning County produced wolfberry dried fruit with a particle size of 380 grains / 50 grams is piled up on the material carrying plate of the plasma treatment equipment, the accumulation thickness is 20cm, and the plasma treatment equipment is a vacuum plasma currently sold on the market A processor generally includes a vacuum chamber and vacuum system, a plasma generator and a control system. For example, RTR1000L-W500 vacuum plasma processor produced by Plasmatreatmentsystem;

[0019] (2) Open the vacuum, the pressure is 10KPa;

[0020] (3) Immediately turn on the plasma generator for plasma treatment under the conditions of 100W power, 40mm distance between poles and 20-30 seconds treatment time;

[0021] (4) Close the equipment, take out the dried wolfberry fruit and pack it.

[0022] After testing,...

Embodiment 2

[0024] The present invention handles the embodiment of the method for pesticide residue on the surface of wolfberry dried fruit, and its steps are:

[0025] (1) earlier the particle size of 10KG Qinghai Qaidam Basin real estate is 280 grains / 50 gram of Chinese wolfberry dried fruit piled up on the material carrying plate of vacuum plasma processor, and stacking thickness is 20cm;

[0026] (2) Open the vacuum, the pressure is 10KPa;

[0027] (3) Immediately turn on the plasma generator for plasma treatment under the conditions of 100W power, 40mm distance between poles and 20-30 seconds treatment time;

[0028] (4) Close the equipment, take out the dried wolfberry fruit and pack it.

[0029] After testing, before processing, the residual amount of omethoate in dried fruit of wolfberry is 0.06PPM, and the residual amount of methyl parathion is 0.02PPM. After the treatment, dried fruit of wolfberry omethoate and methyl parathion are not detected (detected limited to 0.01PPM). ...

Abstract

The invention discloses a method for treatment of pesticide residue on dried Chinese wolfberry surfaces. The method comprises the steps of: (1) firstly stacking dried Chinese wolfberries on a material loading plate of plasma treatment equipment; (2) then turning on vacuum; (3) then starting a plasma generator to conduct plasma treatment; and (4) turning off the equipment, taking out the dried Chinese wolfberries, and performing packaging. The method for treatment of pesticide residue on dried Chinese wolfberry surfaces provided by the invention can effectively reduce the pesticide residue on dried Chinese wolfberry surfaces, improves the quality of dried Chinese wolfberry, does not produce any residue, wastewater or waste gas in the treatment process, and has no secondary pollution. The apparatus adopting the method provided by the invention has the characteristics of low investment cost, low operation cost and economic feasibility.

Description

technical field [0001] The invention belongs to the technical field of food processing, in particular to a method for treating pesticide residues on the surface of wolfberry dried fruit. Background technique [0002] Lycium barbarum is full of treasures. It is a precious medicinal material and tonic. It can nourish the liver, improve eyesight and calm the nerves, making people live longer. Goji berries are rich in goji berry protein, goji berry polysaccharides, vitamin C, phosphorus, iron and other nutrients. . The leaves, flowers and roots of wolfberry are also excellent food supplements. Lycium barbarum polysaccharide (LBP), an active ingredient rich in wolfberry, can significantly enhance bone marrow hematopoietic function and various cellular immune indicators, and can significantly increase the activity content of superoxide dismutase (SOD) in the blood, liver and muscle tissue of the body. It is beneficial to the removal of active oxygen, delaying aging and anti-fat...
