Abstract

The invention discloses a peanut oil extracting technology. The peanut oil extracting technology comprises the following steps: step one, material selection: selecting fresh and full peanut kernels, removing impurities and dust, and under the conditions that the temperature is 8 to 12 DEG C and the humidity is 18 to 22 percent, putting the peanut kernels for 3 to 5 hours or more for standby use; step two, soaking and drying: soaking the standby peanut kernels in the step one in warm water of which the temperature is 30 to 40 DEG C, sending the soaked peanut kernels into a drying baker for drying at the temperature of 35 to 45 DEG C for 45 to 55 minutes, taking out the peanut kernels, rapidly cooling by using a draught fan, and then removing red skin on the outer layers of the peanut kernels. According to the peanut oil extracting technology disclosed by the invention, extracted peanut oil is high in purity and oil yield; in addition, the temperature is well controlled during an extracting process, the quality, the color and the taste of peanut oil are increased, and higher use value and good application prospect are obtained.

Description

technical field [0001] The invention relates to the technical field of peanut oil processing, in particular to a peanut oil refining process. Background technique [0002] Peanut oil is light yellow and transparent, clear in color, fragrant in smell, and delicious in taste. It is a kind of edible oil that is relatively easy to digest. Peanut oil contains more than 80% of unsaturated fatty acids (including 41.2% of oleic acid and 37.6% of linoleic acid); Fatty acid, stearic acid and arachidic acid and other saturated fatty acids are 19.9%. The fatty acid composition of peanut oil is relatively good, which is easy to be digested and absorbed by the human body. According to foreign data, the use of peanut oil can decompose cholesterol in the human body into bile acid and excrete it. Thereby reduce the content of cholesterol in blood plasma, in addition, in peanut oil, also contain the materials useful to human body such as sterol, wheat germ phenol, phospholipid, vitamin E, cho...
