Description
Technical field
The utility model relates to a kind of detecting instrument, especially a kind of aflatoxin ultraviolet fluorescent detecting device.
Background technology
Aflatoxin (Aflatoxins, AFT) is the secondary metabolite of fungi, is mainly produced by bacterial strains such as aspergillus flavus (A.flavus), aspergillus parasiticuses (A.parasiticus); When grain fails to dry in time and stored not at that time, often easily polluted by aspergillus flavus or aspergillus parasiticus and produce this toxoid.Aflatoxin is the hepatotoxin that a kind of toxicity is very strong, the acute of liver or chronic lesion can be caused, except the liver of infringement body, aflatoxin also can cause serious harm to other Various Tissues organs such as kidneys, and more seriously aflatoxin has been proved and has had carcinogenic, teratogenesis, causes " three cause " of cell mutation effect; Extensively be present in the agricultural product such as peanut, corn, wheat class, paddy, serious harm people, animal, avian health.Aflatoxin has B1, B2, G1, G2, M1, M2 etc. multiple, wherein aflatoxin B1 is acknowledged as the strongest natural materials of current carcinogenicity, and within 1993, aflatoxin delimited as I class carcinogenic substance by the Agency for Research on Cancer of the World Health Organization (WHO) (WHO).Research finds, aspergillus flavus is modal fungi in grain and food, but and not all aspergillus flavus strain can produce toxin, according to people's reports such as Matles, from the aspergillus flavus strain that occurring in nature is separated, only having 10% can toxin producing.Therefore, the detection carrying out toxigenic bacterium strain is necessary.
Can fluorescence be there is in aflatoxin under UV-irradiation.AFB1 and AFB2 can produce blue-fluorescence, AFG1 and AFG2 produces green fluorescence.But current market there is no the special equipment for detecting aflatoxin.
Summary of the invention
The purpose of this utility model is, provides a kind of aflatoxin ultraviolet fluorescent detecting device that accurately can detect aflatoxin.
The utility model solves the technical scheme that its technical matters adopts: a kind of aflatoxin ultraviolet fluorescent detecting device, comprise culture tank, Ultraviolet radiation light source, detecting device, described detecting device comprises grating, condenser, fluorescence spectrophotometer mirror, fluorescence display plate, grating is arranged on directly over culture tank, condenser is fixed on directly over grating, fluorescence spectrophotometer mirror is arranged on directly over condenser, fluorescence display plate is arranged on the top of fluorescence spectrophotometer mirror, described fluorescence display plate is fluorescence projection plate, Ultraviolet radiation light source is a luminescence-utraviolet device, the head of illuminator is corresponding with culture tank to be arranged.
Preferably, also comprise detection pedestal, detect pedestal and comprise base, mounting table, culture tank is placed on mounting table, and mounting table is connected by adjusting screw(rod) with base, forms lifting structure.
Preferably, also comprise adjustment seat, adjustment seat is provided with a dwang, and Ultraviolet radiation light source is arranged on dwang by rotating shaft is rotating.
Said structure when in use, nutrient culture media is placed on mounting table, then regulate Ultraviolet radiation light source to irradiate nutrient culture media, make it that fluorescence occur, by carrying out optically focused by condenser after the screening of grating, adding the intensity of high light, then carrying out light splitting by spectroscope and projecting on fluorescence display plate, just significantly can observe the color of fluorescence, the situation of aflatoxin can be judged by fluorescence.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation one of the present embodiment.
Embodiment
Known with reference to figure 1, a kind of aflatoxin ultraviolet fluorescent of the utility model detecting device, comprise culture tank 1, Ultraviolet radiation light source 2, detecting device, described detecting device comprises grating 3, condenser 4, fluorescence spectrophotometer mirror 5, fluorescence display plate 6, grating 3 is arranged on directly over culture tank 1, condenser ' 4 are fixed on directly over grating 3, fluorescence spectrophotometer mirror 5 is arranged on directly over condenser 4, fluorescence display plate 6 is arranged on the top of fluorescence spectrophotometer mirror 5, described fluorescence display plate 6 is fluorescence projection plate, Ultraviolet radiation light source 2 is a luminescence-utraviolet device, the head of illuminator is corresponding with culture tank 1 to be arranged, also comprise detection pedestal, detect pedestal and comprise base 7, mounting table 8, culture tank 1 is placed on mounting table 8, mounting table 8 is connected by adjusting screw(rod) with base 7, form lifting structure, also comprise adjustment seat 9, adjustment seat 9 is provided with a dwang 91, Ultraviolet radiation light source 2 is arranged on dwang 91 by rotating shaft is rotating.
Because the principle of fluorescence can occur aflatoxin under UV-irradiation.AFB1 and AFB2 can produce blue-fluorescence, AFG1 and AFG2 produces green fluorescence.Be inoculated in by mould in nutrient culture media, cultivate 48-72h for 28-30 DEG C, if produce toxin, nutrient culture media can present special fluorescence under UV-irradiation, and this method limit of identification is 5 μ g/mL nutrient culture media.
The utility model utilizes the These characteristics of aflatoxin, design the device of a band UV-detector (wavelength is set as 355-375nm), whether the aspergillus parasiticus and the aspergillus flavus strain that measure screening acquisition produce aflatoxin, set up aflatoxin Control Technology offer help to the feature and exploitation for studying Aspergillus flavus pollution.
Obviously, above-described embodiment is only used to done citing is clearly described, and the restriction not to embodiment.To those of ordinary skill in the art, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of extending out or variation be still in protection domain of the present utility model.
