Davis Test

An alternate view is that juice flavonoid concentration decreases continually during maturation. Lime et ak (55) using the Davis Test found flavonoid concentration Tn TexasTuby Red grapefruit to decrease continually during the growing season. 

Calculations. Record the weight of the pulp in grams. Naringin Analysis (Davis Test)... 

When one examines the analytical methods which are presently available for these bitter compounds, it is clear why the study and control of bitterness in citrus has been so hampered and quality control virtually lacking. For the flavanone, naringin, only an approximate test is available (Davis Test) (see Chapter 5 for a discussion of this method) and for limonin there is no method available for monitoring in processing plants.

MuUiple-Rai e Test and Huber-Davies Test for Outliers... 

An alternative approach to identifying the (somewhat ambivalent) rejection of H, in the ANOVA test is to use a different test for outliers. Several such tests are available but one of the most robust appears (Meier 2000) to be Huber s elimination rule that was not originally formulated as an outlier test (Davies 1988). Moreover, this Huber-Davies test is extremely easy to apply. The first step is to rearrange the test measurement values in increasing order (as for the Multiple-Range Test), thus [xj = 5.51 X3 = 5.91 x, = 6.08 Xj = 7.01 X4 = 7.09]. This allows selection of the median value Xjj,ed(= = 6.08 in our case). The absolute values of the differences i.med = In medl 6 then Calculated and arranged also in...
