Description

Mycotoxin detection incubator capable of improving light-shielding effect

Technical Field

The application relates to the field of mycotoxin detection, in particular to a mycotoxin detection incubator capable of improving a light-shielding effect.

Background

Mycotoxins are toxic secondary metabolites produced by fungi, and one fungus may produce multiple toxins, and multiple fungi may also produce one toxin. More than 1000 mycotoxins have been found in the world, more than 20 mycotoxins have been isolated and identified, of which the most harmful are aflatoxin AFB1, vomitoxin (DON), Zearalenone (ZEN), ochratoxin a (ota), Fumonisin (FUM) and T-2 toxin. Mycotoxins are widely present in grain and oil food and feed. According to the estimation of the food and agriculture organization of the united nations, about 25 percent of grains are polluted by mycotoxin every year in the world, and 2 percent of crops lose nutrition and economic value due to serious pollution. According to the statistics of the national food service bureau, the loss of grain and oil caused by mycotoxin in China is about 3100 million tons, which exceeds the total annual grain yield of 5 western provinces in Gansu, Qinghai, Ningxia, Tibet and Shaanxi. According to the measurement and calculation, if scientific mycotoxin prevention and control and detection measures are provided, the loss of China can be reduced by about 850 billion yuan each year. Mycotoxins also exist widely in traditional Chinese medicinal materials and decoction pieces, and the traditional Chinese medicinal materials can be polluted by various fungi and generate mycotoxins if the traditional Chinese medicinal materials are not dried in time and stored improperly or are not treated properly in the preparation and processing processes after being collected. In recent years, there have been many reports in the literature of contamination of Chinese medicinal materials and other medicinal plants by aflatoxin, ochratoxin A, fumonisin and zearalenone. A plurality of reports show that the traditional Chinese medicine AFB1 is generally polluted at home, the pollution level is 0.12-202.00 mu g.kg < -1 >, and the pollution of medicinal materials such as dried orange peel, dwarf lilyturf tuber, Chinese angelica, coix seed, boat-fruited sterculia seed, medicated leaven and the like is more reported.

Mycotoxins enter our food chain through contaminated grains, feed, traditional Chinese medicines and animal food provided by animals fed with the feed contaminated by mycotoxins, thereby showing carcinogenicity, genotoxicity and teratogenicity to human and livestock, wherein the most toxic is aflatoxin, which is classified as a class I carcinogen by the cancer research Institute (IARC) of the world health organization. Due to the wide pollution and serious harm of the mycotoxin, China stipulates the limit of the mycotoxin in food, feed, traditional Chinese medicinal materials and decoction pieces. The Chinese pharmacopoeia (2020 edition) clearly specifies that the limit of aflatoxin B1 in 24 Chinese medicinal materials and decoction pieces thereof is 5 mug/kg, the limit of the total amount of aflatoxin is l0 mug/kg, and the detection method of aflatoxin is increased.

The detection method of the mycotoxin mainly comprises an instrument method, an enzyme linked immunosorbent assay (ELISA), a colloidal gold test strip method and the like. The method has the advantages that the method is high in accuracy, sensitivity and precision, expensive instruments and reagents are needed, the detection cost is high, the time consumption is long, the operation is complex, the technical level requirement on operators is high, the method has great limitation in the actual application process, and the method is not suitable for rapid field detection; the enzyme-linked immunosorbent assay (ELISA) has good specificity and high sensitivity, but the operation steps are complicated, the detection time is usually 30-120 minutes, the matrix effect exists, the sample pretreatment is complex, the method can only be applied to laboratories, and the method is less and less applied along with the wide application of the colloidal gold test strip. The colloidal gold test strip method is simple to operate, high in detection speed, high in specificity and sensitivity, low in cost and very suitable for rapid field screening of grass-roots and enterprises. In order to promote the flow of a sample in the test strip, the test strip needs to be incubated in the incubation process, and light can influence the accuracy of a detection result, so that shading treatment is needed in the incubation process, and the shading sealing cover is installed on the incubator.
