Embodiment 1

[0018] The present invention handles the method embodiment of organophosphorus pesticide residue on the surface of dried fruit of black wolfberry, and its steps are:

[0019] (1) First stack 5KG of dried black wolfberry fruit produced in Delingha, Qinghai Province on the material carrying plate of the plasma treatment equipment, the accumulation thickness is 15cm, and the plasma treatment equipment is a vacuum plasma treatment machine currently on the market, generally including vacuum Chamber and vacuum system, plasma generator and control system. For example, RTR1000L-W500 vacuum plasma processor produced by Plasma treatment system company;

[0020] (2) Open the vacuum, the pressure is 10KPa;

[0021] (3) Immediately turn on the plasma generator for plasma treatment, the treatment conditions are 80W power, 40mm distance between the poles, and 20 seconds treatment time;

[0022] (4) Close the equipment, take out the dried fruit of black wolfberry, and pack.

[0023] After ...

Embodiment 2

[0025] The present invention handles the method embodiment of organophosphorus pesticide residue on the surface of dried fruit of black wolfberry, and its steps are:

[0026] (1) earlier the black wolfberry dried fruit that 10KG Qinghai Golmud produces is piled up on the material carrying plate of vacuum plasma processor, and stacking thickness is 15cm;

[0027] (2) Open the vacuum, the pressure is 10KPa;

[0028] (3) Immediately turn on the plasma generator for plasma treatment, the treatment conditions are 90W power, 40mm distance between poles, and 20 seconds treatment time;

[0029] (4) Close the equipment, take out the dried fruit of black wolfberry, and pack.

[0030] After testing, before processing, the black wolfberry dried fruit dimethoate residual amount is 0.03PPM, and after the treatment, the black wolfberry dried fruit dimethoate is not detected (detection limit is 0.01PPM).

Abstract

The invention discloses a method for treating organophosphorus pesticide residues on the surface of dried lycium ruthenicum fruits. The method is mainly characterized in that dried lycium ruthenicum fruits are stacked on a material bearing plate of plasma treatment equipment first, and plasma treatment is carried out under a vacuum condition. The invention relates to the method for effectively reducing organophosphorus pesticide residues on the surface of dried lycium barbarum fruits. The method can improve quality of dried lycium ruthenicum fruits, does not generate any residue, waste water and waste gas in a treatment process, and has no secondary pollution. The method provided by the invention is less in investment cost and low in running cost, and has feasibility in economy.

Description

technical field [0001] The invention belongs to the technical field of food processing, in particular to a method for treating organic phosphorus pesticide residues on the surface of dried black wolfberry fruit. Background technique [0002] Black wolfberry is sweet in taste and flat in nature, rich in protein, fat, sugar, free amino acid, organic acid, mineral, trace element, alkaloid, vitamin C, B 1, B 2, calcium, magnesium, copper, zinc, manganese , iron, lead, nickel, cadmium, cobalt, chromium, potassium, sodium and other nutrients, especially the high content of proanthocyanidins. Black wolfberry is distributed in western Qinghai, Jiuquan, Gansu, central Xinjiang, western Inner Mongolia, Ningxia and Tibet. [0003] Due to the good health effects of black wolfberry, the consumption at home and abroad has increased year by year in recent years. After years of hard work by researchers in Qinghai, Gansu and other provinces, the artificial cultivation of black wolfberry ha...
