Cold-pressed cooking oil

 

Most of the vegetable oil we eat in our daily life is squeezed out by a hot automatic mustard oil machine, that is, the oil is cleaned and crushed before being subjected to high-temperature heating treatment, which causes a series of changes in the oil: destroying oil cells and promoting protein Denaturation, reduce oil viscosity, etc., to be suitable for squeezing oil and increase oil yield. However, the crude oil squeezed out from the oil after high temperature treatment is darker in color and higher in acid value, so the crude oil must be refined before consumption. At the same time, high-temperature squeezing of oil causes the biologically active substances (vitamin E, sterols, carotenoids, etc.) in the oil to be greatly lost during the squeezing process, resulting in a waste of resources.

In recent years, with the continuous improvement of people's living standards, people increasingly favor cold-pressed oil in terms of edible oil. Cold pressed oil is sent to the oil press for pressing without heating or low temperature before the oil is pressed. The squeezed oil has a lower temperature and a lower acid value, and generally does not require refining, and refined oil is obtained after precipitation and filtration.

Cold-pressed oil has pure natural characteristics and avoids the adverse effects of traditional high-temperature oil-pressing processing. The cold-pressed oil retains the natural flavor and color of the oil, and completely preserves the physiologically active substances in the oil (vitamin E has anti-aging functions, sterols have skin-building effects and enhance human metabolism). The cold-pressed oil has good color. It is light, but the oil does not smell fragrant and does not get angry. The key is that the cold-pressed oil will not foam or silt the pan when frying.
