Why should we eat less walnut oil from ordinary oil presses? We all know that walnut oil has a special aroma, and stir-frying with walnut oil is very fragrant. In fact, we don’t know that the aroma of walnut oil mainly comes from glucosinolates. Glucoside thiosides are decomposed into isothiocyanates, nitriles, cyanates, and other substances. These free products can cause goiter, liver, and kidney enlargement.

Walnut oil refining equipment is safer than ordinary oil pressing. The refining equipment manufacturer is a manufacturer of oil presses and refining oil pressing equipment, focusing on the production, research, and sales of oil presses for 30 years, and owns its own independent oil press laboratory. Although oil presses have many advantages and directly pressing sesame oil is good, the walnut oil used in presses should be used sparingly. Additionally, walnut oil contains a fatty acid. Long-term excessive intake of erucic acid can cause fat accumulation in the myocardium, thicken blood vessel walls, damage cardiovascular function, and even trigger myocarditis, potentially affecting reproductive function. However, walnut oil refining equipment is different. The walnut oil extracted through refining equipment removes the erucic acid content from the oil, retaining its original nutrients.
Currently, the Food and Agriculture Organization of the United Nations and the World Health Organization recommend that the intake of erucic acid in walnut oil should not exceed 5%. Some edible oils have strict limits on erucic acid content, such as those set by the EU, which cannot exceed 5%, and the content cannot exceed 2%. According to China’s 2004 standard, it cannot exceed 3%. Untreated walnut oil contains up to 40% erucic acid. Refining equipment manufacturers have been striving to produce edible oil, oil presses, and refining equipment. After years of effort and absorbing the experience of domestic and international peers, the oil presses and refining equipment produced not only have high output efficiency but also exceed standards for removing toxic substances such as aflatoxins from edible oil, meeting export standards in Europe and America. Many state-owned grain and oil enterprises as well as medium and large grain and oil enterprises purchase oil presses and refining equipment from our company. The refining equipment manufacturer always insists on being an honest, trustworthy, and responsible enterprise. After-sales service for oil presses and refining equipment purchased from refining equipment manufacturers is much more reliable.
In recent years, excessive benzo[a]pyrene and aflatoxins in edible oils and grains have been present. These highly toxic carcinogens are dozens of times more toxic than cranes. “Dirty” gutter oil, aflatoxins produced in black soil pressing, peanut oil, severe edible oils—all these hidden dangers have forced people to pay closer attention to the safety of edible oils and the entire issue. Although locally pressed walnut oil retains its flavor, its content of glucosinolate and erucic acid is difficult to control and can easily exceed the standard, increasing health risks. For years, refining equipment manufacturers have told customers that it is not suitable for long-term consumption as household oil.
