Solution Overview
Problem
Current methods for processing crude vegetable oils and their byproducts, such as soapstock and wet gums, face challenges in efficient separation of phases, leading to emulsion layer formation and loss of valuable products, as well as environmental concerns due to acidic conditions and corrosive materials.
Innovation Solution
The use of enzymes like protease, lipase, and phospholipase to catalyze the soapstock acidulation process, along with the processing of wet and dry gums to produce acid oil and value-added animal feed products, utilizing a fluidizer like glycerol and alkali to separate and concentrate nitrogen-based materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If conventional acidulation process is used to process soapstock, then fatty acids can be recovered, but emulsion layer formation occurs and valuable products are lost
Solution Approach 1:
The patent introduces enzymes (lipase, protease, phospholipase) as intermediary substances to mediate the acidulation process. These enzymes catalyze the conversion of soapstock components, enabling phase separation without forming stable emulsions that trap valuable products. The enzymes act as biological mediators that facilitate the breakdown of emulsifying agents in soapstock, allowing clean separation of fatty acids from the emulsion layer.
Solution Approach 2:
The patent changes the chemical and physical parameters of the acidulation process by using enzymatic catalysis instead of conventional chemical acidulation. This involves controlling parameters such as pH, temperature, and enzyme concentration to optimize the breakdown of soapstock components. The enzymatic process alters the chemical structure of phospholipids and proteins that cause emulsion formation, thereby improving separation efficiency and reducing product loss.
2Object-affected harmful factors
If conventional refining process is used, then phospholipids can be removed from crude oil, but corrosive materials and environmental concerns arise
Solution Approach 1:
The patent replaces the conventional chemical-mechanical refining process with a biological enzymatic process. Instead of using strong acids and bases that cause corrosion and environmental harm, the patent employs enzymes to catalyze the removal of phospholipids and other impurities from crude oil. This substitution of chemical mechanisms with biological mechanisms eliminates the need for corrosive materials while maintaining effective phospholipid removal.
Solution Approach 2:
The patent converts the harmful emulsion-forming properties of phospholipids and proteins in soapstock into beneficial separation agents. By using enzymes to selectively break down these components, the process transforms substances that originally caused emulsion stability into materials that facilitate clean phase separation. The enzymatic degradation products enable the valuable fatty acids to separate cleanly from the aqueous phase, turning a harmful emulsion problem into a beneficial separation mechanism.
3Quantity of substance
If wet gums are processed to recover phospholipids, then nutraceutical materials can be obtained, but handling and storage difficulties occur due to high moisture content
Solution Approach 1:
The patent utilizes phase transition principles to separate and concentrate phospholipids from the aqueous phase of wet gums. By controlling temperature and solvent conditions, the process induces phase separation where phospholipids transition from a dispersed aqueous state to a concentrated extractable phase. This allows the nutraceutical-rich phospholipid fraction to be separated from the problematic high-moisture matrix, producing a more handleable and storable product while preserving the nutraceutical content.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach minimizes emulsion layer formation, reduces environmental impact, and results in higher quality acid oil with improved oxidative stability and nutraceutical content, while also enabling efficient separation and concentration of valuable compounds like choline for animal feed.
Implementation Method 1
The use of enzymes like protease, lipase, and phospholipase to catalyze the soapstock acidulation process
Implementation Method 2
hydrolyzing the feedstock with a catalyst, for example an enzyme or acid such as sulfuric acid
Implementation Method 3
The homogenized mixture may settle into a first phase and a second phase
Implementation Method 4
The degummed oil may then be treated with aqueous alkali (typically sodium or potassium hydroxide) in order to remove the free fatty acids. The alkali reacts with the free fatty acids present in the crude glycerides to form soap.

AI summary
The present invention provides methods of processing lipid materials such as soapstock, wet gums and dry gums. Enzymes are utilized to catalyze hydrolysis of the lipids materials to recover fatty acids. Addition of organic acids and/or polyols improved yield of fatty acids and reduced formation of emulsion. Lipid materials can be formulated with other agricultural products as new value-added animal feed products. Further, a process for concentrating nitrogenous compounds such as choline, inositol, ethanolamine and serine from phospholipid materials obtained as byproducts from vegetable oil refining is provided. The process involves performing hydrolysis of the gum based products in the presence of an alcoholic solvent and acid catalyst. Post hydrolysis, gums breakdown to oil and water phases which are further separated and concentrated. These concentrated products may be further fractionated to concentrate individual nitrogenous compounds.
