Rank test for Food Product

Rank test is also called the sorting test. In this test, panelists were asked to make the order of the examples were tested according to different levels of sensory quality. In the sequence level, the distance (interval) between the ladder to the top and bottom are not to be the same. Test rankings different from SCOR test. In this test sorted commodities or from serial numbers. The first sequence is always expressed the highest level, the greater the number down. These figures do not declare scalar quantity but the serial number. In the ranking test, comparative examples are not stated. On the scale of the data can be treated as a measurement value, because it can be retrieved and analyzed the average variance. Data on the test rankings as they are not to be treated as the magnitude and variance can not be analyzed, but still may be made on average. Analysis of variance requires special analysis.

Rank test was used to compare sensory attributes of some samples. Panelists will receive one or more coded samples and asked to sort the intensity of specific product attributes (eg sweetness) from the highest to the lowest (rank). Rank test is a rapid test and can be done simultaneously on several examples. Sensory attributes are considered can an attribute liking (hedonic ranking). This test is an extension of the blend ratio test. Panelists received three or more sample code are asked to rank the intensity of the sample for particular characteristics. Rank test is often used to screen one or two best samples from the sample group and not to actually test all the samples. However, there is no indication of large differences between samples obtained since only be evaluated in relation to each other.
