Method of Food Shelves.metal utility cart with wheel

　　Test steps:

　　1. Clept the experimental purpose.

　　① During product development, quickly measure the cargo frame period

　　② When putting into the market, collect dynamic data for the prediction of the actual cargo frame.

　　2. Analyze the ingredients and choose to speed up

　　3. Select the right packaging

　　4. Choose the right storage temperature (usually two temperatures)

　　5. Use the shelf period curve to decide how long the food must be maintained at each temperature

　　6. Determine which test methods are used and how long testing at each temperature at each temperature

　　At any temperature below the highest test temperature, the time between the two tests should not exceed:

　　f = f (q)^(△ T /10).

　　f -Time interval between each test when the highest test temperature T (such as the number of days, the number of weeks);

　　f -Time interval between each test temperature T at a lower test temperature T;

　　△ t = (t a t) ℃

　　Suppose that a kind of dry food must be tested once a month when it is stored at 45 ° C, so according to the calculation of the previous type, it should be tested once every 1.7 March at 40 ° C (△ t = 5) and q = 3. Of course, you need to test more frequently when you do not know Q. In order to minimize statistical errors, there must be at least 6 data points for each storage conditions to minimize statistical errors.
