20160122684 | Method for Aqueous Enzymatic Extraction of Soybean Oil - The present invention provides a method for aqueous enzymatic extraction of soybean oil, which is in the field of extraction processing technology for plant oil. The method comprises treating crushed and peeled soybeans with an extrusion puffing process and a hydrolysis process with an alkaline proteinase, followed by a liquid nitrogen freezing and a high voltage electrostatic thawing process, and finally obtaining soybean oil by centrifugation. The benefits of the present invention includes short extraction time and high extraction yield. It saves up to 93.1% of time in the freezing and thawing process alone. The total oil yield is up to 95.4%. Furthermore, the method of the invention produces high quality oil with a low peroxide value, a low p-anisidine value and a low TOTOX value. | 05-05-2016 |
