Pure sesame oil will appear as a thin, colorless, transparent, large oil drop, and then condense into a number of tiny oil beads. The oil drop of adulterated sesame oil is small and thick, and it is not easy to spread.

2. Color identification: Fill the oil basket with sesame oil, and then pour it into the oil tank from a high place. If the splashing oil is light yellow, it means that rapeseed oil is mixed in the sesame oil.

3. Identification by heating: Put sesame oil into a pot and heat it. If it turns white after heating, it means that lard is mixed in. If it becomes very clear after heating, it means that rapeseed oil is added. If it becomes turbid after heating, it means that rice soup is added, and sediment will appear soon.

4. Odor identification: Take a little oil and rub it in your hand continuously to make it warm. If it has a pure aroma, it is sesame oil; if it has a bean smell, it may be mixed with soybean oil; if it has a spicy taste, it may be mixed with rapeseed oil.

5. Oscillation method: Take a bottle of sesame oil and gently oscillate it. If the bubbles are transparent and disappear quickly, it is generally pure sesame oil. If the bubbles are opaque, yellow, and disappear slowly, it is low-quality sesame oil.

6. Look at the price: refer to the price of sesame seeds. Generally, 2.5 to 3 pounds of sesame seeds can produce one pound of sesame oil. If the price is too low, it is obviously a fake sesame oil blended with essence.
