How to use OleoTest

OleoTest: rapid and accurate test for polar compounds in fry oil

Easy to use, no equipment needed.

When the oil sample is poured into the tube, the blue reagent must reach 140°F / 60°C to dissolve. To achieve this temperature, there are three options:

a) Pour the oil sample at room temperature into the tube, up to the lower part of the label. Put the open tube in a microwave (use a small glass or something similar to prevent the tube from tipping) and heat for 5 to 10 seconds at maximum power. Do not heat for more than 10 seconds.
b) Alternately, heat some water to boiling temperature and dip the (properly closed) tube until the reagent is dissolved, approximately 45 seconds.
c) Place the tube in the anti-burn holder and pour the warm oil sample (at least 140°F / 60°C) up to the lower part of the label. Wait a few seconds, then close the tube tightly and remove the anti-burn holder. If the sample does not melt the blue reagent, follow option a) or b).

Shake the tube well to dissolve the reagent and produce a uniform mixture (about 60 seconds). The color changes as the oil mixes with the reagent.

Allow the mixture to settle for 2 minutes. Then, hold the tube vertically near a source of light / against a light background and compare the obtained color to the color scale.

At the end of the reaction, the mixture (fat and reagent) solidifies.

If the mixture reaches Color 4 (17% to 23% polar compound content), be extremely careful. Studies have shown that at this level of contamination, oil is harmful to the health. Please visit our Documentation page for more information.
