Description
Technical field
The present invention relates to technical field of microbial detection in food paste, more particularly to a kind of conserving case for detecting food paste.
Background technology
Food paste is vulnerable to the pollution of microorganism during processing, transport and storing.Food hygiene supervision is needed to food
Microorganism is detected in product sauce.
In food paste production process, along with detecting whether there is quality of the certain micro-organisms to ensure final products.
In the prior art, be generally required for very those skilled in the art to observe and explain assay, thus need it is a kind of more
Method that is convenient, intuitively, accurately being detected to microorganism in food paste.
The content of the invention
It is an object of the invention to provide a kind of conserving case for detecting food paste, to solve above-mentioned technical problem.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of conserving case for detecting food paste, it is characterised in that：Including insulation box body and the sample being placed in incubation chamber body
Card, being horizontally disposed with the incubation chamber body has object disposing platform, and object disposing platform will be separated into upper and lower two cavitys, put in incubation chamber body
Limbers is provided with thing platform, is connected by limbers between upper and lower two cavitys, the lower chamber of the insulation box body passes through
Water inlet pipe and outlet pipe connection temperature adjustment water tank, are provided with heater, on the water inlet pipe and outlet pipe in the temperature adjustment water tank
Control valve is provided with, water circulating pump is provided with the water inlet pipe；
The sample card includes substrate and upper cover plate, and the upper surface of the substrate and the lower surface of upper cover plate are flat for glass
Face, the upper end of the substrate offers culture tank, and oiliness coating, the upper end of the substrate are provided with around the upper shed of culture tank
Edge is provided with upward chimb, and the upper cover plate is covered on the upper end of substrate, between the edge of upper cover plate and the chimb of substrate
There is gap.
The insulation box body is incubated using water-bath, liquid level of the horizontal plane in incubation chamber body higher than nutrient solution in culture tank.
Multiple culture tanks are offered on the substrate, detected sample and nutrient solution can be simultaneously added in each culture tank,
Multiple culture tanks carry out test experience simultaneously, and testing result is relatively reliable, and testing staff's observation is more directly perceived, easily determines.
The upper cover plate is clear glass, is easy to testing staff to observe and judges testing result.
Sample to be detected and nutrient solution are added in culture tank, and upper cover plate is covered with substrate, the upper surface of substrate and upper lid
The lower surface of plate for glass planar can be very good laminating, then between the edge and substrate chimb with dropper to upper cover plate between
Added water in gap, sealed substrate and upper cover plate with water, form moisture film between substrate and upper cover plate, and by substrate and the sky of upper cover plate
Gas is all discharged, because scribbling oiliness coating around the upper shed of culture tank, moisture film will not cross the oiliness coating and enter culture
In groove, and if persistently producing gas in culture tank, then gas will enter between substrate and upper cover plate, and moisture film is arranged,
Bubble one by one is formed between substrate and upper cover plate, observation is highly convenient for.
The detection method of microorganism, comprises the following steps in food paste：
A () takes food paste to be detected and is put into beaker, to the sterilized water that 10 times are added in beaker, be thoroughly mixed,
Food paste detection liquid is made, food paste detection liquid is placed in 6-8 hours in the gnotobasis that temperature is 30-35 DEG C；
B () is taken in the culture tank of food paste detection liquid addition sample card of 1ml, then to nutrient solution is added in culture tank, cover
The upper cover plate of upper sample card, and with water seal (closing sample card substrate and upper cover plate between gap)；
C () sample after water seal is placed in incubated in incubation chamber body, 32-34 DEG C of temperature, cultivate 36 hours；
Whether bubble is generated in the water seal face of (d) observation sample card, generating bubble then proves with the presence of microorganism, does not have
Having generation bubble then proves no microorganism；
Following material component is mainly contained in every liter of nutrient solution：
Green tea powder can not only provide carbon source and nitrogen source, meet the demand of bacterial growth, and can adjust nutrient solution acid
Basicity, with the breeding of microorganism, the pH value of nutrient solution can change because of the breeding of microorganism, and green tea powder early stage is sour
Property material dissolution it is very fast, and later stage alkaline matter starts dissolution, can play adjustment effect to the acid-base value of nutrient solution.Tobacco leaf powder
Addition can avoid nutrient solution into peracidity, while can also provide carbon source and nitrogen source, animal tallow, golden cicada powder, gelatin are micro-
Biological growth provides sufficient carbon source and nitrogen source；Sodium chloride can maintain osmotic pressure in a balanced way；Lactose is fermentable coliform
Carbohydrate；Potassium dihydrogen phosphate and dipotassium hydrogen phosphate are buffers.
The beneficial effects of the invention are as follows：
The conserving case that the present invention is provided, for being detected to the microorganism in food paste, the conserving case is protected using water-bath
The mode of temperature is incubated to sample card, for the growth of microorganism provides suitable environment, can simultaneously carry out multigroup test experience,
And testing result can be observed simultaneously, need to be by observe whether produced between upper cover plate and substrate bubble and can determine that only
No with the presence of microorganism, the detection method is simple to operate, and the judgement to testing result is more directly perceived, it is not easy to erroneous judgement occur.
