Patent No. 200510127341.6 is a patent for a method for rapidly determining the total number of bacteria in raw milk, which discloses a method for quickly measuring the total number of bacteria in milk samples by using the methylene blue reduction method, but this method is only used to detect the total number of bacteria in raw milk, and the steps It is cumbersome and not suitable as a quick test method for the sterilization effect of refrigerators
After reviewing, no relevant literature and patents were found to quickly test the sterilization effect of refrigerators

Embodiment Construction
[0013] Such as figure 1 with figure 2 As shown, the gas-dissolving device 10 used in the present invention includes an air pump 4 and a test tube 8. The test tube 8 contains a reagent 7 (the reagent in the present invention refers to a milk test sample), and the air inlet 3 of the air pump 4 is arranged in a refrigerator 11 2 air outlets of the inner sterilizing device 1 to ensure that the sterilizing components produced by the sterilizing device 1 enter as much as possible into the air inlet 3 of the air pump 4 . The outlet pipe 6 of the air pump 4 leads into the bottom of the reagent 7 in the test tube 8 .
[0014] A method for rapidly detecting the sterilization effect of a refrigerator according to the present invention uses the above-mentioned gas-dissolving device, and proceeds according to the following steps:
[0015] 1. Prepare a (0.01±0.005) g / 300mL methylene blue aqueous solution; 2. Prepare a milk test sample whose fading time of methylene blue is less than or e...

The invention discloses a rapid detection method for the sterilizing effect of a refrigerator. The rapid detection method sequentially comprises the following steps of (1) preparing (0.01+ / -0.005)g / 300mL of methylene blue water solution; (2) preparing milk experiment samples, wherein the color fading time of methylene blue is less than or equal to 10 minutes; (3) respectively adding equivalent deionized water into the two milk experiment samples and carrying out uniform mixing, respectively putting the two milk experiment samples into a bacteria removing refrigerator and a general refrigerator which is not provided with a sterilizing device, filling gas processed by the sterilizing device in the refrigerator into the milk experiment samples by utilizing a gas dissolving device, and respectively taking out the two milk experiment samples after the two milk experiment samples are put in the refrigerators for the same time; and (4) carrying out uniform mixing after equivalent methylene blue agents are respectively dropwise added into the two milk experiment samples, and taking color variances of the two uniformly-mixed milk experiment samples as indexes for detecting the sterilizing effect of the bacteria removing refrigerator. The rapid detection method has the advantages that the operation is simple, the detection time of the total bacterial count of raw milk is greatly shortened, the blank of the rapid detection method for the sterilizing effect of the refrigerator is filled, and the practical value is very high.
Description
technical field [0001] The invention relates to a rapid detection method for the sterilization effect of a refrigerator. Background technique [0002] At present, the refrigerator freezer is mainly used to hold fresh fruits and vegetables, food and so on. The temperature of the refrigerator is generally 0-10°C. This temperature range can inhibit the reproduction of some bacteria, but it cannot kill fungi such as psychrophilic bacteria, mesophilic bacteria and molds. After a long time, the food put in the refrigerator will still deteriorate. Rot and spoilage. Therefore, a refrigerator with a sterilizing function emerges at the historic moment. The sterilizing refrigerator can effectively kill bacteria and mold on the items in the refrigerator and prolong the freshness of the food in the refrigerator. However, at present, most of the detection methods for the sterilization effect of sterilizing refrigerators use the plate counting method, which requires culture medium to cul...
