The Rigorous Control of High - Quality Peanut Oil: From Raw Materials to Your Table

Peanut oil holds a significant position in daily life. It is not only a staple in many kitchens but also a key ingredient in various cuisines. In this article, we will take you through the meticulous process of producing high - quality peanut oil, from the selection of raw materials to the final product on your table, which will enhance your confidence in our brand and make you a loyal customer.

1. Shelling of Peanut in Shell

The journey of our peanut oil starts with the shelling of peanuts. We source high - quality peanuts with thick and intact shells. Specialized shelling machines are used to ensure that the peanuts are separated from their shells efficiently. Through this process, about 98% of the peanuts can be shelled, and the damage rate of peanuts is controlled within 2%, guaranteeing the integrity of the peanuts for subsequent processing.

2. Comparison between Hot - Pressing and Cold - Pressing Processes

There are two main methods for extracting peanut oil: hot - pressing and cold - pressing. Hot - pressing involves heating the peanuts to around 120 - 130°C before extraction. This method can increase the oil yield, typically reaching about 45 - 50%. The hot - pressed peanut oil has a rich fragrance and is suitable for stir - frying and deep - frying. On the other hand, cold - pressing is carried out at a lower temperature, below 60°C. Although the oil yield is relatively lower, around 38 - 42%, the cold - pressed peanut oil retains more nutrients and has a lighter flavor, which is ideal for salad dressings and cold dishes. You can choose the type of oil according to your cooking needs. So, which method do you prefer for your peanut oil extraction?

3. Peanut Cleaning and Pre - treatment

After shelling, the peanuts need to be cleaned and pre - treated. They are washed with clean water to remove impurities such as dust, sand, and small stones. Then, they are dried to reduce the moisture content to about 8 - 10%. This step is crucial as it can prevent the growth of mold during storage and processing, ensuring the quality and safety of the peanuts.

4. The Crucial Role of Baking Temperature in Cooking

In the cooking process, the baking temperature is a key factor. When baking peanuts, the temperature is precisely controlled between 150 - 160°C. This temperature range can not only enhance the fragrance of peanuts but also make the structure of peanuts looser, which is beneficial for subsequent oil extraction. If the temperature is too high, the peanuts may be charred, affecting the taste and quality of the oil; if the temperature is too low, the fragrance and oil yield will be affected.

5. The Impact of Crushing on Oil Yield

The crushing process also has a significant impact on the oil yield. We use advanced crushing equipment to crush the peanuts into small particles. The particle size is controlled to ensure that the oil cells in the peanuts are fully broken, increasing the contact area between the peanuts and the extraction medium. This can effectively improve the oil yield. Generally, after proper crushing, the oil extraction rate can be increased by about 3 - 5%.

6. Oil Extraction Process and Data

The oil extraction process is carried out in a professional extraction device. Whether using hot - pressing or cold - pressing, the extraction time is strictly controlled. For hot - pressing, the extraction usually takes about 2 - 3 hours, while for cold - pressing, it may take 4 - 5 hours. Through these strict processes, we can ensure that the oil extracted is of high quality, with low acid value and peroxide value, meeting national food safety standards.

7. Re - utilization of Oil Cake

After oil extraction, the remaining oil cake is not wasted. It can be used as high - quality animal feed or as raw material for organic fertilizer production. For example, adding oil cake to animal feed can increase the protein content of the feed, promoting the growth and development of animals. This re - utilization not only reduces waste but also reflects our commitment to environmental protection.

8. Refining and Filling

The extracted crude oil needs to go through a refining process, including degumming, deacidification, decolorization, and deodorization. Through these processes, the impurities and odors in the oil are removed, making the oil clearer, more stable, and longer - lasting. Finally, the refined peanut oil is filled into clean and hygienic bottles, ready to be delivered to your table.

In conclusion, our high - quality peanut oil production process is strictly controlled from raw materials to your table. Every step is carefully monitored to ensure the quality and safety of the product. You can buy our peanut oil with confidence, and we are sure that you will become a loyal customer of our brand.
