Packing manner of microbial solid inoculum

Abstract

The invention discloses a packing manner of microbial solid inoculum. The packing manner comprises the steps that a material is softened by heating and compression-molded or blister-molded in a mold to form a blister with a plurality of three-dimensional spaces; each solid space is filled with the solid inoculum with a shape matching and a certain three-dimensional geometry; an instrument is usedto test the quality and qualified filling of the blister; a coated substrate material is covered with the surface of the filled blister; and the blister is sealed with the substrate. The microbial solid inoculum has high visualization degree, non-toxic, tasteless and high resistance to gas and moisture; and the packing manner can effectively prevent the microbial solid inoculum from being polluted, has good high temperature and low temperature resistance, can resist medium erosion, has high adhesion, can be used according to the required amount, can effectively prevent other microbial solid inoculum in the blister from being polluted, and has high production, popularization and application value.

Description

technical field [0001] The invention relates to a packaging method, in particular to a packaging method of a solid microorganism agent, and belongs to the field of food microorganisms. Background technique [0002] With the continuous improvement of people's living standards, people pay more attention to food safety, and the research on food microbiology related fields is also gradually strengthened. In the process of microbiological testing, the correct use of standard strains as quality control or positive control is the prerequisite for ensuring reasonable and accurate test results. At present, there are mainly the following packaging methods for microbial standard strains or reference materials at home and abroad: the bacteria powder is packaged in ampoules / vials, which has good sealing performance, but the bacteria powder is less intuitive when labeling instructions. Poor, one-time use cost is high, the glass material is not only heavy, increases transportation costs, ...

Problems solved by technology

At present, there are mainly the following packaging methods for microbial standard strains or reference materials at home and abroad: the bacteria powder is packaged in ampoules / vials, which has good sealing performance, but the bacteria powder is less intuitive when labeling instructions. Poor, one-time use cost is high, the glass material is not only heavy, increases transportation costs, and is easy to break, it is difficult to obtain the bacterial powder, if the bacterial powder is not used up at one time, repeated sampling will lead to contamination of the remaining bacterial powder in the bottle, take it out It is more likely to pollute and absorb moisture after falling back again; although the cost of storing bacteria in inclined test tubes and cryopreservation tubes is low, it is very easy to cause microbial death and is more likely to cause pollution

Therefore, the packaging methods of existing microbial strains have certain limitations in the actual application process. At present, there is no microbial bacterial agent with low cost, easy preservation, good sealing, no pollution, built-in microbial agent and can be used multiple times. Packing
