Abstract: The present disclosure discloses a method for producing a structural soybean-based meat analog by simple shearing and heating in a Couette shear flow pressure tank, which belongs to the field of soybean protein product development. The method includes: step 1, preparing a soybean protein isolate and an active wheat gluten; step 2, preparing a sample material of protein mixture; step 3, filling the sample material of protein mixture; and step 4, carrying out a texture analysis. The present disclosure clarifies the process of applying simple shear flow and heating to soybean protein isolate and wheat gluten dispersion, provides proof of concept for the production of structural meat analogs, and confirms that the application of simple shearing and heating is the key to obtain structural plant protein products.

Abstract: 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.
