Choice of food physical and chemical testing methods

One of the tasks of food physical and chemical testing is to provide accurate and reliable testing data.

(1) Choose among different criteria

1.

For example, "GB/T5009.

2.

(2) Choose between two different inspection methods of the same standard

The "GB/T5009.

1.

Generally speaking, the test results of several standard test methods of "the first method as the arbitration method" are basically the same, but the accuracy and precision of the first method are higher, and the requirements for the equipment used are also higher

2.

The detection results of several parallel methods in the standard may be different, so you can not choose at will, you should choose the applicable detection method according to the characteristics of the product itself

What needs to be reminded is that the two types of detection methods cannot be confused, that is, do not mistake the first method in the parallel method as the arbitration method, and do not mistake the several methods containing the first method (arbitration method) as the parallel method

For this reason, "GB/T5009.

(3) Make a choice after comprehensively considering the testing purpose, testing cost and other factors

The appropriate detection method should be selected according to the purpose of the test, the time required to obtain the test result, and the cost of the test
