Why Cold-Pressed Sesame Oil Is More Fragrant and Nutritious: Revealing the Secrets to Preserving Vitamin E and Unsaturated Fatty Acids

Why is cold-pressed sesame oil more fragrant and nutritious?

When it comes to sesame oil, many people love its natural aroma and rich nutrients. Are you also curious why "cold-pressed sesame oil" tastes purer and is more nutritious than traditional hot-pressed oil? The secret lies in how the low-temperature process maximizes the preservation of key components in sesame oil—vitamin E and unsaturated fatty acids.

Users are most concerned about: oil yield, nutrition, and ease of use.

While traditional high-temperature pressing yields good oil output, the high temperatures destroy vitamin E and unsaturated fatty acids in sesame seeds, leading to reduced aroma and nutritional value. Many small oil mills also worry about the complex operation and potential impact on oil yield of low-temperature cold-pressing equipment, raising concerns about the risks of transitioning to other methods.

What exactly makes cold-pressed food "cold"?

Simply put, the temperature of cold-pressed sesame oil is generally controlled below 40°C. Compared to the 70-90°C commonly found in high-temperature pressing, this gentler temperature prevents fat-soluble nutrients from being destroyed by high temperatures, thus preserving the oil's aroma and health benefits.

Don't be fooled by misconceptions: Is cold-pressed oil really low in oil yield?

Many people mistakenly believe that low-temperature cold pressing yields less output. In reality, thanks to the technology of hydraulic sesame oil presses:

1. Automatic temperature control and hydraulic pressure regulation

2. Suitable for sesame seeds with different hardness

3. Simple to operate and easy to maintain

Data from a small oil mill shows that after introducing QIE Group's hydraulic oil press, the oil yield increased by about 3%, and the customer repurchase rate increased by 40%.

Unveiling the Inside of a Hydraulic Oil Press

Core advantages of hydraulic sesame oil press:

1. Hydraulic system : Stabilizes screw pressure to achieve uniform pressing.

2. Temperature-controlled pressing chamber : Real-time monitoring ensures a low-temperature range, preventing nutrient loss.

3. Suitable for various sesame seed hardness levels : No need for frequent manual adjustment

4. Easy to use : Automatic mode, beginners can get started quickly.

Scientific data support: According to a 2023 study in China Oils and Fats, cold-pressed sesame oil retains over 90% of vitamin E and unsaturated fatty acids, while high-temperature pressing only retains about 65% and 70%, respectively.

Real-life case study: The encouraging changes in a traditional oil mill

After a small oil mill in Sudan upgraded to a QIE Group hydraulic sesame oil press:

1. The aroma of the oil was significantly enhanced.

2. User feedback indicates that "the oil is more fragrant and has a smoother texture."

3. Repeat customers increased from 50% to 70%.

4. The factory owner stated that the equipment is easy to operate, has stable automatic temperature control, and low maintenance costs.

Operating Techniques and Maintenance Tips

1. Maintain regular equipment cleaning

2. Regularly check the hydraulic oil and temperature control device.

3. Utilize automated operation modes to reduce human error

4. Each batch of sesame oil retains its nutritional value.

Do you have these questions too?

Q1: Is cold-pressed sesame oil suitable for all types of sesame?

Yes, our hydraulic sesame oil press is designed to be compatible with sesame seeds of different hardness, and automatically adjusts pressure and temperature to ensure complete nutrition.

Q2: Is it normal for the oil yield to decrease when cold pressing equipment is put into use?

Modern hydraulic equipment can maximize the recovery of oil output, while the traditional view that a decrease in oil output is mainly due to performance issues with older equipment.

Q3: What are the health effects of Vitamin E and unsaturated fatty acids?

They are powerful antioxidants that help protect the cardiovascular system, support the immune system, and enhance the nutritional value of natural oils.

Q4: Can cold-pressed sesame oil be used for high-temperature frying?

It is recommended to use it for cooking at medium to low temperatures or in cold dishes to preserve its aroma and nutritional value.

From stable hydraulic pressure to a precise temperature control system, our hydraulic sesame oil press uses technology to safeguard every drop of low-temperature cold-pressed sesame oil, ensuring that vitamin E and the natural essence of unsaturated fatty acids are perfectly locked in, truly achieving both aroma and nutrition.
