In today's market, consumers are increasingly demanding high - quality peanut oil. However, common quality issues such as off - flavors, low nutritional value, and potential contaminants often make consumers hesitant when making a choice. So, what are the secrets behind the production of high - quality peanut oil? Let's explore together.
The quality of raw materials is the cornerstone of high - quality peanut oil production. During the peanut pretreatment process, strict selection is carried out. Only peanuts with high oil content, usually above 45%, and free from mold, pests, and other impurities are selected. For example, in a large - scale peanut oil production enterprise, they reject about 15% of the peanuts that do not meet the standards. This strict raw material control ensures that the subsequent production process starts on a high - quality basis.
Baking: Baking is a crucial step that affects the flavor and quality of peanut oil. The temperature and time of baking need to be precisely controlled. Generally, the baking temperature is set between 130 - 150°C for about 30 - 40 minutes. This can not only enhance the nutty flavor of peanuts but also inactivate some enzymes that may affect the quality of the oil.
Crushing: After baking, the peanuts are crushed into small particles. The particle size of the crushed peanuts is an important factor affecting the oil yield. Usually, the particle size is controlled within 2 - 3 mm, which can ensure a high oil extraction rate in the subsequent pressing process.
Oil Extraction: There are mainly two methods of oil extraction: pressing and solvent extraction. High - quality peanut oil production often uses physical pressing to ensure the naturalness and purity of the oil. The pressing pressure is usually controlled at about 30 - 40 MPa, and the oil yield can reach about 40 - 45%.
Refining is necessary to remove impurities, free fatty acids, and other substances in the crude oil, improving the clarity, stability, and shelf - life of the oil. Common refining methods include degumming, deacidification, decolorization, and deodorization. For example, in the decolorization process, activated clay is used, and the dosage is usually about 2 - 3% of the oil mass. This can effectively remove pigments in the oil and make the oil clearer and more transparent.
Let's take a well - known peanut oil brand as an example. Through strict production standards and advanced technology, their peanut oil has a peroxide value of less than 0.2 g/100g, which is far lower than the national standard of 0.25 g/100g. And the acid value is controlled at about 0.3 mg KOH/g, while the national standard is 0.6 mg KOH/g. These data show the high quality of their products.
In conclusion, the production of high - quality peanut oil requires strict control in every link from raw materials to finished products. The enterprise adheres to strict production standards and uses advanced and sophisticated technologies, which not only ensures the high quality of the peanut oil but also reflects the enterprise's pursuit of excellence. When you choose peanut oil, why not choose this brand that is committed to quality and has strict production processes?
