At present, the cooking process of cooking oil is mainly two kinds: solvent extraction and oil press machine.
The process of extracting oil from oil is extracted from the raw material by mechanical extrusion, which is divided into cold press and heat press. Difference between hot press is the material before oil Fried baking, cooking, such as heat treatment, and cold pressed without these pretreatment process, is the temperature control in a certain range of physics.
Pressed oil, refers to use vegetable oil production by cold pressing process, the temperature generally below 60 ℃. The cold press can simply be understood as having no heat at all.
Due to the cold pressing process without steaming and frying, retained oil flavor and natural color, at the same time retains more nutrients (monounsaturated fatty acids and polyunsaturated fatty acids, vitamins, minerals), no solvent residual, there is no trans fatty acids, so as to make the product original, more beneficial to health.
But this kind of method of oil yield efficiency is relatively low, at present has not been widely used, so commercial cold oil price on the high side, appears in the image of a high-end oil products.
Cold oil conforms to the people to the new concept of healthy living, many consumers when buying oil, not only to compare prices, nutrition index is also an important reference, cold oil has become a highlight of edible oil market in our country.
At the same time, our country's grain and oil industry advocate moderate processing, to avoid and prevent excessive edible oil processing, cold pressing technology research and development of iterative also become one of the main oil companies rivalry.
In general, the cold oil can keep the original nutrition, the quality of the oil is more pure, it is in line with the need of the public to pursue the healthy and environmental protection.
Cold press has the advantage of cold pressed and hot press have hot press, some people pursuit of taste, some people pursuit of fragrance, consumer can according to the needs of the oneself, the choice of diversification.
