Abstract

The invention relates to the technical field of processing for agricultural products and byproducts, in particular to a method for extracting soybean oil. The method for extracting the soybean oil comprises the following steps: successively using a hot peeling technology to peel soybeans, grinding the soybeans by using a grinder, then carrying out extrusion, freezing extruded materials after grinding, and adding alkaline protease and water to carry out enzymatic hydrolysis to obtain an enzymatic hydrolysate; performing centrifugal separation after finishing the enzymatic hydrolysis to obtain free oil, separating the free oil and obtaining the soybean oil after standing. The soybean oil extracted by the invention is low in peroxide value, strong in oxidation resistance, and greatly improved in product quality, and further can be applied to large-scale continuous production for creating favorable conditions for actual production and industrial application of the soybean oil.

Description

technical field [0001] The invention relates to the technical field of agricultural and sideline food processing, in particular to a method for extracting soybean oil. Background technique [0002] Soybean is the main food crop in my country and an important source of protein. With the gradual improvement of people's awareness of its nutritional value and health function, soybean products are more and more favored by more people. Emerging Soybean [0003] The development of soybean products, the transformation of traditional soybean production technology and the consumption of soybean food will become a trend, which will drive the rapid development of soybean products in my country to industrialization. In 2009, my country's soybean output was about 14.5 million tons, the usage was about 54.5 million tons, and the import was about 40 million tons, of which about 8 million tons were used in the food industry, accounting for 15% of the usage; About 4 million tons of processe...
