High-quality Peanut Oil Refining Process: A Crucial Step to Enhance Quality

In the world of edible oils, high-quality peanut oil stands out for its rich flavor and numerous health benefits. The production of such premium peanut oil is a meticulous process that involves multiple strict procedures. Let's take a closer look at how this exceptional product is made.

Raw Material Control

The journey of high-quality peanut oil begins with the careful selection of raw materials. The company uses a grading sieve to remove impurities, such as stones, sand, and dust, from the peanuts. This step is crucial as impurities can not only affect the quality of the final product but also cause damage to the production equipment. Moreover, the grading sieve also helps to separate immature and moldy peanuts. Immature peanuts may have a lower oil content, while moldy peanuts can produce harmful substances, such as aflatoxins, which pose a serious threat to human health. By strictly controlling the raw materials, the company ensures that only the best peanuts are used in the production process.

Key Production Steps

Roasting

Roasting is a critical step in creating the rich, fragrant flavor of high-quality peanut oil. The peanuts are roasted at a temperature between 180°C and 200°C. This precise temperature control not only brings out the natural aroma of the peanuts but also helps to improve the oil yield. According to industry data, peanuts roasted at this temperature range can increase the oil extraction rate by approximately 5% compared to those roasted at lower temperatures.

Crushing

After roasting, the peanuts are crushed to break them into smaller pieces. This step is essential for increasing the surface area of the peanuts, which allows for more efficient oil extraction. The company uses advanced crushing equipment to ensure that the peanuts are crushed evenly, further enhancing the oil yield.

Oil Extraction

During the oil extraction process, a screw-type peanut oil press is used. The company strictly controls the parameters of the press, such as pressure and temperature, to ensure a high-quality oil extraction. By maintaining optimal conditions, the press can extract up to 45% of the oil from the peanuts, a rate that is significantly higher than the industry average.

The Refining Process

The refining process is the final and most important step in producing high-quality peanut oil. Although the oil extracted from the previous steps already has a good quality, it still contains some impurities, such as phospholipids, free fatty acids, and pigments. These impurities can affect the clarity, flavor, and shelf life of the oil. Therefore, the refining process is necessary to remove these impurities and improve the overall quality of the oil.

The refining process typically includes degumming, neutralization, bleaching, and deodorization. Degumming removes phospholipids, neutralization reduces free fatty acids, bleaching removes pigments, and deodorization eliminates unpleasant odors. Through these processes, the peanut oil becomes clearer, purer, and more stable, with a longer shelf life.

Case Studies and Data

To illustrate the effectiveness of the company's strict production standards and advanced technology, let's look at some case studies and data. In a recent quality inspection, the company's peanut oil passed all the national and international quality standards with flying colors. The acid value of the oil was less than 0.2 mg KOH/g, which is far lower than the industry standard of 0.6 mg KOH/g. This indicates that the oil has a high level of purity and stability.

Moreover, consumer surveys have shown that more than 90% of consumers who have tried the company's peanut oil are satisfied with its quality and flavor. This high level of customer satisfaction is a testament to the company's commitment to producing high-quality products.
