Fusarium moniliforme qualitative and standard sample in bean flour and preparation method thereof

Abstract

The invention belongs to the technical field of biology and particularly relates to a fusarium moniliforme qualitative and standard sample in bean flour and a preparation method thereof. According to the technological index that fusarium moniliforme has taxonomic significance, the problems of a fusarium moniliforme material standard sample tracing reference system and reference indexes are solved, the technological index that fusarium moniliforme has taxonomic significance is applied to definite value analysis of the standard sample, toxin-producing fungus fusarium moniliforme definite in source is used for simulating naturally-polluted bean flour samples in a national biosafety standard sample system framework on the basis of a research result of a qualitative testing theory of the standard sample, fusarium moniliforme ACCC36127 spore polluted sterile bean flour in the logarithmic phase is acquired and is flapped and mixed through a mixing instrument, sub-packaging is performed, freeze-drying is performed, and the fusarium moniliforme material standard sample complete in biology and toxin-producing information is prepared, the fusarium moniliforme material standard sample which has the real tracing significance is acquired and belongs to domestic first-time development of classifying and grading standard samples, and great significance is achieved.

Description

technical field [0001] The invention belongs to the field of biological technology, in particular to a qualitative standard sample of Fusarium moniliforme in soybean flour and a preparation method thereof. Background technique [0002] The World Food and Agriculture Organization (FAO) reports that about 25% of the world's crops are polluted by fungi and their mycotoxins every year, and about 2% of the crops lose their nutritional value and economic value due to serious pollution. Direct and indirect losses caused by pollution may reach tens of billions of dollars. [0003] Among the currently known mycotoxins, Fusarium moniliforme is an important plant pathogen that harms crops such as wheat, corn, rice, and vegetables, causing severe yield reduction. The mycotoxin zearalenone produced has Strong reproductive toxicity and Qi effect. At present, for the detection of mycotoxins, our country mainly uses physical and chemical methods, which can only detect the toxins that have...
