Polyglycerin Ester Separation for Diacylglycerol Fat Yield
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing fat or oil compositions with high diacylglycerol content face challenges in achieving high yield and maintaining favorable taste and flavor, as they often require large amounts of emulsifiers, leading to low yield and flavor deterioration during solid-liquid separation.
Innovation Solution
The method involves adding a polyglycerin fatty acid ester with a high average polymerization degree to a fat or oil composition containing 40% or more diacylglycerol, followed by cooling and separating the crystal precipitate from the liquid portion, which efficiently separates high-melting components and maintains a favorable external appearance at room temperature with reduced emulsifier usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If an emulsifier is added as a separation aid during wintering to suppress crystallization, then the fat or oil remains clear, but the taste and flavor deteriorate and yield decreases due to large amounts of emulsifier required
Solution Approach 1:
The patent uses a specific polyglycerin fatty acid ester (with average polymerization degree of glycerin being 20 or more) as an intermediary substance to facilitate crystal separation. This mediator enables efficient solid-liquid separation without requiring large amounts of emulsifiers, thus preventing taste and flavor deterioration while maintaining clarity.
Solution Approach 2:
The patent changes the parameter of the separation aid from conventional emulsifiers to polyglycerin fatty acid esters with specific polymerization degree (20 or more). This parameter change results in improved separation efficiency, reduced emulsifier requirements, and preservation of taste and flavor while maintaining product clarity.
2Ease of operation
If a large amount of emulsifier is used during solid-liquid separation, then crystal separation is facilitated, but yield decreases and production cost increases
Solution Approach 1:
The polyglycerin fatty acid ester acts as an effective intermediary that enhances crystal separation efficiency. Its molecular structure with high polymerization degree allows it to interact effectively with diacylglycerol crystals, facilitating their separation from the liquid phase without requiring large quantities, thus preserving yield.
Solution Approach 2:
By changing the type and molecular characteristics (average polymerization degree ≥20) of the separation aid, the patent achieves superior separation performance at lower concentrations. This parameter optimization resolves the contradiction between separation efficiency and yield preservation.
3Manufacturing precision
If conventional emulsifiers are used for solid-liquid separation, then separation is achieved, but the external appearance and flavor of the fat or oil composition deteriorate
Solution Approach 1:
The polyglycerin fatty acid ester serves as a specialized intermediary that is compatible with the fat or oil matrix. It facilitates effective solid-liquid separation through its unique molecular properties while remaining neutral to the sensory characteristics of the product, thus avoiding flavor and appearance deterioration.
Solution Approach 2:
The patent optimizes the molecular parameters of the separation aid by selecting polyglycerin fatty acid esters with average polymerization degree of 20 or more. This parameter specification ensures effective separation while maintaining the sensory quality of the final product.
