Deep Dive: Cold-Pressed vs. Hot-Pressed Sesame Oil

You might be wondering, "Is the sesame oil I'm buying really suitable for cold dishes?" To answer this, let's first understand the fundamental differences between cold-pressed and hot-pressed sesame oil.

The principle of these two processes mainly lies in the temperature. Cold-pressing is carried out at a low temperature, usually below 60°C. This low - temperature environment is crucial for retaining nutrients like vitamin E and unsaturated fatty acids. In fact, studies show that cold - pressed sesame oil can retain up to 90% of vitamin E and about 85% of linolenic acid. On the other hand, hot - pressing involves high temperatures, often above 150°C. While it can increase the oil yield, it significantly damages the flavor and reduces the nutrient retention. For example, the retention rate of vitamin E in hot - pressed oil drops to around 30%, and linolenic acid retention is only about 40%.

Application Scenarios: Why Different Choices?

Why do high - end restaurants prefer cold - pressed sesame oil for cold dishes and seasoning? The answer lies in its rich aroma and intact nutrition. Cold - pressed oil can bring out the best in ingredients, adding a delicate and natural flavor to dishes. It's like a secret weapon for chefs to create culinary masterpieces.

On the industrial side, hot - pressed sesame oil is often the choice. The high yield of hot - pressing makes it more cost - effective for large - scale production. However, if you're concerned about the flavor and nutrition of your food, cold - pressed oil is definitely the way to go.

Your Guide to Homemade Cold - Pressed Sesame Oil

Making cold - pressed sesame oil at home is easier than you think! Here's a step - by - step guide on using a small cold - press machine.

Step 1: Prepare the Sesame Seeds

Choose high - quality sesame seeds. You can soak them in water for a few hours to make them softer, which helps in the pressing process.

Step 2: Set the Temperature

Keep the temperature below 60°C. Most small cold - press machines have a temperature control function. Make sure to set it correctly to retain the nutrients.

Step 3: Press the Seeds

Feed the sesame seeds into the cold - press machine. You'll see the fresh oil flowing out gradually. It's a satisfying process!

Common Mistakes and Maintenance

One common mistake is not cleaning the machine properly after use. Residual oil and seeds can affect the next pressing. Clean the machine with warm water and a mild detergent regularly. Also, store the oil in a cool, dark place to maintain its quality.

Extended Value: Sesame Oil in a Healthy Lifestyle

During the fat - loss period, cold - pressed sesame oil can be a great addition to your diet. Its unsaturated fatty acids can help with metabolism. In Chinese cuisine, upgrading your cooking oil to cold - pressed sesame oil can bring a new level of flavor to your dishes.
