Can the oil extracted by hydraulic press be consumed?

Whether the oil extracted by a hydraulic press can be consumed directly depends on multiple factors, including the type of oil press, the quality of the raw materials, the oil pressing process, and subsequent processing.

Overview of hydraulic oil press

Hydraulic oil press is one of the equipment that uses physical pressing to produce vegetable oil. Its process characteristics include frying, crushing, steaming, pressing and other steps. The temperature during the pressing process is relatively low, which helps to preserve the original color, aroma and flavor of the vegetable oil. Hydraulic oil presses are widely used for pressing high-quality edible oils such as tea seed oil, olive oil, flaxseed oil, etc., and are also adopted by some peanut, soybean, and rapeseed oil manufacturers.

Is the oil extracted by the hydraulic press edible

• Raw material quality: Whether the oil extracted by the hydraulic oil press is edible depends first and foremost on the quality of the raw materials. If the raw materials are fresh, free from mold, and meet food safety standards, then the extracted oil is theoretically edible.
• Oil extraction process: Although the temperature of the hydraulic oil press is relatively low during the oil extraction process, some impurities such as microorganisms, toxins, suspended solids, etc. may still be introduced. If these impurities are not further processed, they may affect the quality and safety of the oil.

• Subsequent processing: The oil extracted by hydraulic oil presses is usually crude oil, which needs to undergo certain processing before it can be consumed. These treatments include filtration, degumming, deacidification, decolorization, deodorization and other steps to remove impurities, improve the quality and safety of the oil. If the extracted oil has not undergone these treatments or is not thoroughly processed, there may be health risks associated with consuming it directly.

In summary, the oil extracted by hydraulic presses is theoretically edible, provided that the raw material quality is qualified, the oil extraction process is standardized, the subsequent processing is appropriate, and it meets relevant national standards and regulations. If consumers use a hydraulic oil press to extract oil at home and plan to consume it, it is recommended to choose fresh, mold free ingredients and strictly follow the instructions of the oil press for operation and subsequent processing. At the same time, it is also necessary to pay attention to the storage conditions and time of oil to avoid the deterioration of oil quality affecting health.
