Abstract

The invention discloses a preparation process of refining peanut oil. The preparation process is characterized by comprising the following steps of: a, preparing the peanut kernel, cleaning and removing impurity, and checking the peanut kernel; b, drying for 30-60minutes at 60-80 DEG C; c, cooling at normal temperature for 1-2 hours; d, pulling off red skin in a huller, performing the secondary checking, and removing the peanut kernel with red skin and discolored peanut kernel; e, crushing the peanut kernel, adding water, standing for 30-60 minutes, and squeezing for 3-5 times; f, combining the squeezed peanut oil, filtering, adding ethanol, and mixing; g, separating the mixed oil of the peanut oil and the ethanol, reducing pressure and exhausting solution to obtain the finished product peanut oil. The preparation process disclosed by the invention is high in production efficiency, good in peanut taste, simple in process step and capable of satisfying the demand of the people on the peanut.

Description

technical field [0001] The invention relates to a peanut production process, in particular to a preparation process for refining peanut oil. Background technique [0002] Peanut oil is light yellow and transparent, with clear color, fragrant smell and delicious taste. It is a kind of edible oil that is relatively easy to digest. Peanut oil contains more than 80% unsaturated fatty acids (including 41.2% oleic acid and 37.6% linoleic acid). In addition, it also contains 19.9% ​​of saturated fatty acids such as palmitic acid, stearic acid and arachidic acid. The fatty acid composition of peanut oil is relatively good, which is easy for human body to digest and absorb. The peanut oil preparation process in the prior art has low production efficiency, distorted taste of peanut oil, cumbersome process steps, and cannot meet people's demand for natural peanut oil. [0003] Therefore, there is an urgent need for an improved technology to solve this problem in the prior art. Con...
