Problems solved by technology

Organic solvent extraction oil extraction rate is relatively high, but organic solvent residues, long-term consumption will cause harm to human health, and after oil extraction, soybean meal can only be used as feed or fertilizer, which limits the utilization of resources; hot pressing However, due to high-temperature processing, the oil produces harmful substances such as trans fatty acids and oil polymers. After oil extraction, the soybean meal has a high degree of denaturation and cannot be used for high added value. Indirectly increased production costs

Abstract

The invention discloses a method used for preparing soybean oil through enzymatic hydrolysis, and belongs to the technical field of grain and oil. The method comprises following steps: 1, soybean powder is prepared; 2, soybean slurry is prepared; 3, enzyme treatment is carried out; 4, low pressure plasma treatment is carried out; and 5, cold pressing is carried out. The method is capable of avoiding generation of harmful substances such as trans-fatty acids and grease polymers in grease; denaturation of soybean meal obtained via oil extraction is avoided, and high added value utilization can be realized; the prepared soybean oil is thick in fragrance, is red and yellow in color, and is high in transparency.

Description

technical field [0001] The invention belongs to the technical field of grain and oil, and in particular relates to a method for preparing soybean oil by an enzymatic hydrolysis method. Background technique [0002] The current conventional industrial oil production methods continue to use the traditional hot pressing process and organic solvent extraction. Although these two oil extraction processes have high oil extraction efficiency, they all have their own disadvantages. Organic solvent extraction oil extraction rate is relatively high, but organic solvent residues, long-term consumption will cause harm to human health, and after oil extraction, soybean meal can only be used as feed or fertilizer, which limits the utilization of resources; hot pressing However, due to high-temperature processing, the oil produces harmful substances such as trans fatty acids and oil polymers. After oil extraction, the soybean meal has a high degree of denaturation and cannot be used for hi...
