What is the difference between pure press and press oil?

1, different purity

Pure pressing means that the purity of oil is relatively clean, and there is no other taste after removing impurities in oil. Luzhou-flavor pressing refers to oil with original flavor.

2. Different characteristics

Pure press oil is directly sent to the oil press for pressing without heating or low temperature before pressing oil. Luzhou-flavor oil is hot fried. Generally, the oil is washed and crushed before pressing, and then heated at high temperature. Peanuts can smell fragrance when heated.

Step 3: Different colors

Pure press oil is bright in color and light in taste. Luzhou-flavor oil press is the extraction of oil crop seeds after baking, which has a special smell, dark color and high yield.

Pure press oil is shown in the figure:

Luzhou-flavor oil pressing is shown as follows:

4. Different temperatures

Pure press oil is generally processed at an environment below 60℃. Before pressing Luzhou-flavor oil, the oil was heated at high temperature to make a series of changes in the oil.

5, the process is different

Production technology of pure oil pressing: from oil pressing, cleaning, shell-kernel separation, seed kernel, low-temperature drying, conditioning, cold pressing and refined oil filtration. Luzhou-flavor oil pressing technology: oil seed, cleaning, shell-kernel separation, seed kernel drying and cooling, crushing and peeling, blank rolling, high-temperature steaming and frying, high-temperature pressing, precipitation and filtration, refining and refined oil.

Squeeze peanut oil:

Peanuts are crushed, carefully selected (peanuts are separated from the shell), fried until they are 6-8 ripe, and then physically squeezed by an oil press. The pressed products are pressed peanut oil and peanut residue, which is edible. Oil press is divided into vertical oil press and spiral oil press.

Peanut oil is light yellow and transparent, with clear color, fragrant smell and delicious taste. It is an edible oil that is easy to digest. Peanut oil contains more than 80% unsaturated fatty acids (including oleic acid 4 1.2% and linoleic acid 37.6%). In addition, it also contains 19.9% saturated fatty acids such as palmitic acid, stearic acid and arachidic acid.

From the above contents, the fatty acid composition of peanut oil is relatively good, which is easy for human body to digest and absorb. According to foreign data, the use of peanut oil can decompose cholesterol in human body into bile acids and excrete them, thus reducing the cholesterol content in plasma.
