Test to detect contamination of mustard oil with argemone oil?
**Core Concept**
Argemone oil contamination in mustard oil can lead to the presence of sanguinarine, a toxic alkaloid that can cause epidemic dropsy, a condition characterized by edema, joint pain, and heart problems. The detection of argemone oil contamination is crucial to ensure the safety of edible oils.
**Why the Correct Answer is Right**
The test to detect argemone oil contamination involves the use of the Sanguinarine Test Kit, which detects the presence of sanguinarine in the oil sample. This test is based on the principle that sanguinarine reacts with picric acid to form a yellow-colored complex, which can be detected visually or spectroscopically. The test is specific to sanguinarine and does not react with other compounds present in mustard oil.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it refers to the use of gas chromatography, which is a general analytical technique used to separate and identify components of a mixture, but it is not specific to detecting argemone oil contamination.
**Option B:** This option is incorrect because it refers to the use of thin-layer chromatography (TLC), which is a technique used to separate and identify compounds based on their adsorption on a solid support, but it is not specific to detecting sanguinarine.
**Option C:** This option is incorrect because it refers to the use of high-performance liquid chromatography (HPLC), which is a technique used to separate and identify compounds based on their interaction with a stationary phase, but it is not specific to detecting argemone oil contamination in mustard oil.
**Clinical Pearl / High-Yield Fact**
The Sanguinarine Test Kit is a simple, cost-effective, and rapid method for detecting argemone oil contamination in mustard oil, and it is widely used in laboratories and food testing facilities.
**Correct Answer: D. Sanguinarine Test Kit.**
