Description
Technical field
The invention belongs to food processing technology field, espespecially a kind of method processing dried fruit of lycium barbarum surface residues of pesticides.
Background technology
Matrimony vine whole body is all precious, is famous and precious medicinal material and invigorant, can nourishes the liver to improve visual acuity and calm the nerves, make us long-lived.Matrimony vine is rich in the multiple nutritional components such as matrimony vine albumen, LBP-X, vitamin C, phosphorus, iron, and energy qi-restoratives production of sperm, is used for being used as medicine or making tea, steep in wine, stew, if often drink, more can improves the health.The leaf of matrimony vine, flower, root are also first-class cuisines tonics.The active ingredient LBP-X (LBP) be rich in matrimony vine has obvious humidification to hemopoietic function of bone marrow and every Immunological Markers for Cell-Mediated Immunity, the active quantities of superoxide dismutase (SOD) of body blood, liver and muscular tissue can be significantly improved, thus be conducive to the removing of active oxygen, delay senility and antifatigue; Increase the quantity of antibody forming cell, improve antibody effects.The producing region of matrimony vine mainly concentrates on the Northwest, and the matrimony vine in Ningxia is the most famous, and the Lycium barbarum. L Quality on the ground such as Gansu, Qinghai is also very high in addition.
Because matrimony vine has good health-care effect, consumption figure at home and abroad increases year by year in recent years.But the residues of pesticides excessive problem of matrimony vine seriously limits the development of matrimony vine industry.Matrimony vine diseases and pests mainly contains aphid, wood louse, goitre mite, rust mite, red cecidomyiia, thrips, moth fruit moth, black fruit, powdery mildew etc.In the prevention and control of plant diseases, pest control, some thatch agricultures are in order to kill disease and pest as early as possible, use some high malicious persistent pesticide, or overproof heavy dose uses agricultural chemicals, or after use agricultural chemicals, be eager to pursue larger economic interests, do not wait agricultural chemicals volatilization, be degraded to finite concentration, pluck matrimony vine in advance, cause that agriculture is residual to exceed standard.The edible residual matrimony vine exceeded standard of agriculture can cause people's accumulate poisoning or acute and chronic poisoning.
Summary of the invention
The object of the present invention is to provide a kind of method processing dried fruit of lycium barbarum surface residues of pesticides, it under vacuum, pass through plasma treatment, reduce the residues of pesticides on dried fruit of lycium barbarum surface, thus improve dried fruit of lycium barbarum quality, do not produce any residue, waste water and waste gas in processing procedure, non-secondary pollution, adopt plant investment expense of the present invention few, operating cost is low.
To achieve these goals, technical solution of the present invention is: a kind of method processing dried fruit of lycium barbarum surface residues of pesticides, it comprises the steps:
(1) first dried fruit of lycium barbarum is deposited on the material loading plate of apparatus for processing plasma;
(2) vacuum is opened after;
(3) open plasma generator after, carry out plasma treatment;
(4) closing device, takes out dried fruit of lycium barbarum, packaging.
The method of process dried fruit of lycium barbarum surface of the present invention residues of pesticides, the thickness that in wherein said step (1), dried fruit of lycium barbarum is piled up is 2-50cm.
The method of process dried fruit of lycium barbarum surface of the present invention residues of pesticides, the pressure in wherein said step (2) under vacuum condition is 1-20KPa.
The method of process dried fruit of lycium barbarum surface of the present invention residues of pesticides, the pressure in wherein said step (2) under vacuum condition reaches 1-20KPa, opens the plasma generator described in step (3) immediately.
The method of process dried fruit of lycium barbarum of the present invention surface residues of pesticides, the plasma process conditions of wherein said step (3) is power 50-200W, the two poles of the earth needle gage is from being 20-50mm, processing time 20-90 second.
After adopting such scheme, the present invention is by pure physical method, utilize the 4th state plasma of material that the remains of pesticide remaining in surface of agricultural products and inside has been done harmless treatment, namely under vacuum, pass through plasma treatment, reduce the residues of pesticides on dried fruit of lycium barbarum surface, thus improve dried fruit of lycium barbarum quality, be specially: the main operational principle of plasma generator is that low-voltage is risen to positive high voltage and negative high voltage by booster circuit, positive high voltage and negative high voltage ionized air (mainly oxygen) is utilized to produce a large amount of cations and anion, the quantity of anion is greater than the quantity (quantity of anion is approximately 1.5 times of amount of positive ions) of cation, plasma is the coherent condition that a kind of matter energy is higher, its energy range compares gaseous state, liquid, solid matter is all high, be called as the 4th state of material, there is the electronics of certain Energy distribution, ion and neutral particle, can by the energy transferring of oneself to the molecule on fruit surface and atom when the shock with fruit surface, produce series of physical and chemical process, some particles also can be injected into fruit surface and cause collision, scattering, excite, reset, isomery, defect, crystallization and decrystallized, thus the residues of pesticides of plant surface are forwarded, degraded agriculture is residual, when carrying out plasma treatment, vacuumize, the residues of pesticides of fruit surface under vacuum conditions, along with the raising of vacuum, adhesion between the residual and fruit inside of agriculture also reduces, simultaneously under vacuum condition, passage between the residual and surface of the agriculture also making to have infiltrated fruit surface inside is opened, be convenient to plasma and go deep into epidermis inside, with remains of pesticide effect, further reduction dried fruit of lycium barbarum surface residues of pesticides, any residue is not produced in processing procedure, waste water and waste gas, non-secondary pollution, adopt plant investment expense of the present invention few, operating cost is low.
