Problems solved by technology

In order to make sesame oil have a strong fragrance, the temperature of frying seeds in the production process of sesame sesame oil usually needs to reach above 160°C, and even the local temperature can reach above 200°C. Hidden danger
Another problem that high-temperature frying seeds brings to the quality of sesame oil is that the color is too dark
In order to retain the fragrance of sesame oil to the greatest extent, the refining of sesame oil generally only adopts the method of static precipitation or filtration. This simple refining method has almost no effect on the removal and decolorization of benzopyrene in sesame oil, thus affecting the quality of sesame oil. quality

Abstract

The invention relates to sesame oil and specifically discloses a preparation method of high-quality sesame oil. The preparation method comprises the following steps: S1, stir-frying cleaned sesame seeds, squeezing, and carrying out oil-residue separation to obtain crude oil; and S2, carrying out adsorption treatment by adding an adsorbent into the crude oil, carrying out fine filtration, and collecting a filtered oil liquid so as to obtain high-quality sesame oil. Raw materials of the adsorbent comprise wood chip, montmorillonite and a dodecyl dimethyl betaine solution. The preparation methodhas an excellent effect of removing benzopyrene and color, and quality of sesame oil is improved.

Description

technical field [0001] The invention relates to sesame oil, in particular to a preparation method of high-quality sesame oil. Background technique [0002] Sesame sesame oil is a high-end edible oil with good flavor and high nutritional value, which is obtained by water substitution or pressing after sesame seeds are roasted at high temperature. In order to make sesame oil have a strong fragrance, the temperature of frying seeds in the production process of sesame sesame oil usually needs to reach above 160°C, and even the local temperature can reach above 200°C. There is a hidden danger. Another problem that high-temperature frying seeds brings to the quality of sesame oil is that the color is too dark. In order to retain the fragrance of sesame oil to the greatest extent, the refining of sesame oil generally only adopts the method of static precipitation or filtration. This simple refining method has almost no effect on the removal and decolorization of benzopyrene in se...
