Cold-pressed and hot-pressed in recent years, with the continuous improvement of people's living standards, more and more people of all ages in terms of cold edible oil extraction. Cold pressed oil before the press is heated by a low temperature without a state, into the press the press. Squeeze lower oil temperature, acid value is low, generally do not need refining, after precipitation and filtration to obtain refined oil.
Our daily lives are mostly edible vegetable oil hot oil, hot squeeze oil is high, the majority of hot-pressed oil refinery. That is, before the first oil through oil extraction cleaning, high temperature heat treatment after the crushing, so that a series of changes of internal fuel: fuel cell damage, promote protein denaturation, reduced oil viscosity, increase the oil yield. But, after the high temperature treatment of the oil squeeze color darker hair oil, acid value increased, so after eating crude oil must be refined. While high-temperature oil extraction so that the oil in a large loss of biologically active substances in the crushing process, resulting in a waste of resources.

Cold oil extraction has natural properties, to avoid the adverse effects of conventional oil extraction process produces a high temperature. Cold-pressed oil refined oil retains the natural flavor and color, complete preservation of the oil in the physiologically active substances, cold oil extraction authentic, is to choose a healthy lifestyle. But most of the oil is not suitable for cold pressing. Gossypol in cottonseed oil toxins and deterioration of aflatoxin, etc., must be refined to remove.
Cold oil extraction of raw materials must be carefully selected, otherwise due to different maturity and raw materials contained in the impact of harmful substances is cold-pressed oil without going through the wok fry, you can extract oil cold pressed. Cold squeeze oil color is good, relatively pale, greasy but not fragrant, do not get angry. The key is cold-pressed oil in frying something when not frothing, not silt pot is its advantages.
Hot-pressed oil is pressed again after wok fried, cooked greasy oil extraction pure, fragrant, especially in the oil-rich sesame kind is fragrant. The disadvantage is not treated in time, when the pot fried stuff will play Mo silt pot, but after simple treatment can solve this problem.
