Cold pressing of oil : The cold pressing method is to send the oil directly to the oil press for pressing without going through high temperature or low temperature, usually at a temperature below 60 degrees Celsius. Oil hot pressing: In the hot pressing method, the oil is usually cleaned and crushed before the oil is pressed, and then heated at a high temperature, which will cause the destruction of the oil cells, promote the denaturation of the protein, and reduce the viscosity of the oil, so as to achieve the purpose of pressing. Both cold-pressed oil and hot-pressed oil are physical pressing methods. The differences between the two are as follows: 1. Different extraction process Due to the particularity of cold-pressed oil, special hydraulic oil presses are often used for pressing. Hot oil presses are usually screw presses. Before hot pressing oil, the oil should be cleaned, crushed and then heated at high temperature, and then extracted. However, cold-pressed oil has a shorter she...
