Have you ever wondered how high - quality export - grade peanut oil is made? In this article, we'll take you through the entire production process, from shelling peanuts to the final edible product, and reveal how each step affects the oil yield.
The journey of peanut oil starts with shelling the peanuts. High - quality peanuts are carefully selected, and then the shells are removed. After that, the peanuts are thoroughly cleaned to remove dirt, stones, and other impurities. This step is crucial as any foreign matter can affect the quality and oil yield of the final product. Studies show that proper cleaning can improve the oil yield by about 2 - 3%.
There are two main methods for extracting peanut oil: hot - pressing and cold - pressing. Each method has its own unique characteristics and impacts on the oil yield.
Hot - pressing involves heating the peanuts before extraction. The peanuts are usually roasted at a temperature between 120 - 150°C. This process can break down the cell walls of the peanuts, making it easier to release the oil. Generally, hot - pressing can achieve an oil yield of around 45 - 50%. The oil produced by hot - pressing has a rich flavor and is more suitable for cooking that requires high - temperature frying.
Cold - pressing, on the other hand, is carried out at a lower temperature, usually below 60°C. This method preserves more nutrients in the oil, such as vitamins and antioxidants. However, the oil yield is relatively lower, typically around 35 - 40%. Cold - pressed peanut oil has a milder flavor and is often preferred for salad dressings or for those who want to retain the natural nutrients of the peanuts.
After the pressing process, there are still other important steps, such as filtration and refining. Filtration removes any remaining solid particles from the oil, while refining further purifies the oil by removing impurities, odors, and colors. These steps ensure the clarity, stability, and safety of the peanut oil.
Our brand has been dedicated to producing high - quality export - grade peanut oil for years. Through continuous research and optimization of the production process, we have achieved an average oil yield of 48% in our hot - pressing production line, which is significantly higher than the industry average. This not only reflects our professional control over the production process but also our pursuit of high - quality products.
Q: Which method is better, hot - pressing or cold - pressing? A: It depends on your needs. If you prefer a rich - flavored oil for high - temperature cooking, hot - pressing is a better choice. If you value the retention of nutrients and a mild flavor, cold - pressing is more suitable.
Q: How can I ensure the quality of the peanut oil I buy? A: Look for brands with strict quality control processes. Our brand, for example, conducts multiple inspections at every stage of production to ensure the safety and quality of our peanut oil.
