Application

Acid value and peroxide value of edible oil is most commonly used physical and chemical indicators to evaluate compliance with health standards. This method is suitable for edible oil in the acid value and peroxide value of rapid quantitative determination of the scene.

Reagent constitute

Peroxide value test liquid A, peroxide value test solution B, three plastic straw scale (3ml), two bottles of control bottle, one piece of Color Card, one book instruction.

Period of validity

Store in cool dry place away from light and sealed, the period of validity is one year.

Detection steps:

Peroxide value test: Use the 3ml plastic pipette to take 2 drops of oil samples (about 0.05g) in the control bottle, drops 6 drops of test solution A, shake it and then drop a drop of test solution B, shake again, after 1 minute compare with the standard colorimetric card to find and control the gradation of color on the card is similar to the peroxide value of edible oil in the general content.

Announcement

1. Peroxide value test, comparing with the standard colorimetric card, the time should not exceed 3 minutes, the longer the sample color will be deeper.

2. For the exceeded the standard of peroxide value, the samples should be sent to the laboratory for further quantification.

3. After use, test containers should be cleaned immediately to prepare for the next experiment.
