Which test uncoated paper test or Sudan test is the most sensitive to small quantities of lipids?

for me, i think the uncoated paper test is more sensitive than Sudan iv test. This is because Sudan iv test can only soluble in certain solvent thus make it harder to define either the solution that is tested is really have lipid in it although there is not. The uncoated paper test can show if there is lipid the the solution if greasy transparent spot comes out from the uncoated paper.

Importance of Sudan IV?
Like lipids, the chemical Sudan IV is not soluble in water; it is, however, soluble in lipids. Therefore to test for the presence of lipids in a solution you will use a Sudan IV Test. In this test dark red Sudan IV is added to a solution along with ethanol to dissolve any possible lipids. If lipids are present the Sudan IV will stain them reddish-orange, giving a positive test.

What does the Sudan red solution test for?

What substance is stained by Sudan dye?
fats (Lipids)
Why does lipids turn redish brown when added to Sudan iv dye?
Sudan dye is lipid -soluble dye, thus, it will turn any lipids to red. It mixes with it.
Does hamburger juice have lipids?
Yes, hamburger juice has lipids. A way to test for lipids is to use Sudan IV and when exposed to Sudan IV it separates (due to its non polar characteristics) and there is a concentrate in the upper half of the test tube (the part that contains the lipids) which then gets dyed red. This equals positive lipids.
Sudan lll dye solution has a high affinity for?
Lipids!
What happens when vegetable oil and Sudan III solution is mixed?
Sudan iii is used to identify lipids. It makes small pink particles in the presence of lipids. Whwn vegetable oil and sudan iii is mixed,floating pink particles can be seen.
Indicator for lipids?
transparency. If a few drops of a substance are placed onto a paper product, such as a paper towel, then you will be able to tell if it contains lipids or not. If it shows to be clear or transparent then it is positive for lipids.
