To understand which is better, pressed oil or leached oil, it is necessary to clarify what is pressed oil and leached oil. What is the difference between the two. Only in this way can we better distinguish the difference between the two.
The difference between pressed oil and leached oil
1. The production process is different: the squeezing oil mainly adopts the physical squeezing method, while the leaching oil is mainly the chemical leaching method.
The production process of the physical pressing method requires that the raw materials should be selected. The oil is crushed, steamed, and squeezed after removing impurities and stones to separate the oil from the oil. The fried seeds are added during the pressing process and the oil press equipment After being squeezed, it is made with high-tech filtration and extraction technology. The chemical leaching method is an oil-making method that uses the principle of chemical extraction, selects a certain solvent that can dissolve grease, and extracts the grease in the oil through contact with the oil (soaking or spraying). The oil produced by leaching method has low residual oil in meal (high oil yield)”
2. Different nutrient components: the pressed oil is full of color, fragrance and taste, and retains various nutrients. The extracted oil is colorless and tasteless, and most of the nutrients are destroyed after processing.
3. The composition of the raw materials is different: the squeezing method uses a physical squeezing process to retain the original flavor of the raw materials, so the requirements for the raw materials are relatively high, and the raw materials are required to be fresh. The price of pressed oil tends to be higher.
Advantages of squeezed oil and leached oil
Advantages of leaching oil: It has the advantages of less residual oil in the meal, high oil yield, low processing cost, low labor intensity, good production conditions, and good meal quality. Generally, the oil yield of oil produced by the leaching method is 3% higher than that of the pressing method, which can improve the economic benefits of the enterprise.
Advantages of squeezed oil: It is the process of squeezing the grease out of the squeezed material by means of external mechanical force. This method does not involve the addition of chemical substances, retains the rich nutrients in the oil, has no chemical pollution, does not contain any chemical preservatives, and ensures the nutrition and deliciousness of the product, which meets the needs of human health. Its advantages are hygiene and pollution.
By comparison, it can be found that the economic value of pressed oil is higher.
