Hot pressed oil, that is, the oil is cleaned and crushed before being subjected to high-temperature heating treatment, and then pressed with a hot press oil machine, which destroys oil cells, promotes protein denaturation, reduces oil viscosity, etc., so as to be suitable for squeezing oil and increasing oil yield. The hot-pressed oil has a pure and fragrant oil taste, especially from those rich in oil such as sesame and peanuts. The disadvantage is that it will froth when frying things in the pan without treatment.
The cold pressing method means that the oil is sent to the cold oil press machine for pressing without heating or at a low temperature. The cold pressing method is generally processed in an environment below 60°C. The raw materials of cold pressed oil must be carefully selected, otherwise the quality of cold pressed oil will be affected. The cold-pressed product oil retains the natural flavor and color of the oil, and completely preserves the physiologically active substances in the oil. The degree of protein denaturation is low, and the protein is easier to comprehensively utilize. Generally speaking, cold-pressed oil has good color and lighter color.
