1. Gas chromatography: This method separates and analyzes components in the corn oil to determine its composition.

2. Mass spectrometry: This technique can identify different compounds in the corn oil based on their molecular weight.

3. Acid value test: This test measures the amount of acidic substances present in the corn oil, which can indicate its freshness and quality.

4. Peroxide value test: This method determines the level of peroxides in the corn oil, which can indicate the extent of oxidation and rancidity.

5. Iodine value test: This test measures the degree of unsaturation in the corn oil, which can indicate its susceptibility to oxidation.

6. Free fatty acids test: This method determines the concentration of free fatty acids in the corn oil, which can indicate the level of hydrolytic rancidity.

7. Color measurement: This technique quantifies the color of the corn oil, which can give information about its purity and processing.

8. Odor evaluation: This sensory evaluation method assesses the smell of the corn oil to detect any off-flavors or rancidity.

9. Moisture content determination: This test measures the amount of moisture present in the corn oil, which can affect its shelf life and stability.

10. Viscosity measurement: This method determines the resistance of the corn oil to flow, which can give information about its consistency and quality.

11. Microscopic analysis: This technique examines the corn oil under a microscope to detect any foreign particles or impurities.

12. Refractive index measurement: This test measures how much light is refracted in the corn oil, which can provide information about its purity and composition.

13. Specific gravity test: This method determines the density of the corn oil compared to water, which can give information about its quality and authenticity.

14. Fluorescence spectroscopy: This technique analyzes the fluorescent properties of the corn oil to detect any contaminants or adulterants.

15. Differential scanning calorimetry: This method measures the heat flow in the corn oil to determine its thermal properties and purity.
