Basic Copper Gluconate High Copper Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Copper gluconate has a lower copper loading compared to copper sulfate pentahydrate, limiting its economic and spatial use in foods and oral applications due to the need for higher loadings to achieve comparable copper content, while also being gentler on the digestive system.
Innovation Solution
Development of basic copper gluconate with a molecular formula Cu[OH][C6H11O7]—X H2O, which has a 1:1:1 metal:ligand:hydroxyl ratio and a theoretical copper content of 23.1%, achieved by neutralizing glucono delta-lactone with basic copper carbonate, resulting in a higher copper loading without sacrificing aqueous solubility or gut sensitivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If copper gluconate is used instead of copper sulfate pentahydrate to reduce digestive system irritation, then gentleness on the digestive system is improved, but copper loading decreases
Solution Approach 1:
The patent changes the chemical composition parameters of copper gluconate by incorporating hydroxyl groups to form basic copper gluconate with formula Cu[OH][C6H11O7]—X H2O. This parameter change increases the copper loading from 14.4% in conventional copper gluconate to 23.1% in basic copper gluconate, while preserving the gentle digestive properties that make copper gluconate preferable to copper sulfate pentahydrate.
2Quantity of substance
If higher loading of copper gluconate is used to achieve comparable copper content, then copper content level is improved, but economic efficiency and spatial utilization worsen
Solution Approach 1:
By modifying the chemical parameters of copper gluconate to create basic copper gluconate with increased copper content (23.1% vs 14.4%), the patent eliminates the need for higher loadings to achieve target copper levels. This improves economic efficiency and spatial utilization in food and beverage formulations.
3Quantity of substance
If higher loading of copper gluconate is used to achieve comparable copper content, then copper content level is improved, but spatial utilization worsens
Solution Approach 1:
The patent achieves higher copper content (23.1%) through chemical parameter modification rather than increasing the physical quantity or volume of additive used. This improves spatial utilization in formulations by requiring less volume to achieve the same copper content level.
