Solution Overview
Problem
Current methods for processing soybean oil sediments to produce phospholipids face challenges such as low acetone-insoluble content, high production costs, environmental pollution, and food safety hazards, limiting the industrial application and market penetration of high-purity powder phospholipids.
Innovation Solution
A self-aggregating hydrous phospholipid is produced by soaking soybean oil sediments in water to achieve saturated water absorption, with a water content of 70-80 g/100 g and an acetone-insoluble content of 92.5-95.5 g/100 g, allowing for the preparation of high-purity powder phospholipids without organic solvents, thereby reducing production costs and environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If hydration method is used to prepare concentrated phospholipids, then production cost is reduced and process is simplified, but acetone-insoluble content is too low (60-65 g/100 g)
Solution Approach 1:
The patent changes the physical-chemical parameters of the hydration process by controlling water content (60-80 g/100 g), temperature (40-60°C), and pH (5.0-7.0) to optimize phospholipid aggregation and separation, achieving high acetone-insoluble content (90-95 g/100 g) while maintaining low production cost
Solution Approach 2:
The patent utilizes the self-aggregation property of phospholipids in aqueous solution to automatically separate from impurities without requiring chemical reagents or complex processing steps, reducing production cost while improving purity
2Manufacturing precision
If solvent method is used to prepare powder phospholipids, then acetone-insoluble content is high (95-98 g/100 g), but production cost increases and environmental pollution occurs
Solution Approach 1:
The patent replaces the chemical solvent extraction system with a physical hydration and self-aggregation system, eliminating the need for acetone solvent while achieving comparable or superior acetone-insoluble content (90-95 g/100 g) and reducing production cost
3Manufacturing precision
If chemical bleaching is used in hydration method, then phospholipid concentration is improved, but environmental pollution and food safety hazards occur
Solution Approach 1:
The patent converts the naturally occurring self-aggregation property of phospholipids in water into a beneficial separation mechanism, eliminating the need for chemical bleaching agents and their associated environmental pollution and food safety hazards while maintaining high phospholipid concentration (90-95 g/100 g)
