Raw-Milk Lactoferrin Purification for Native Bioactivity Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lactoferrin preparations derived from processed milk sources suffer from denaturation, reduced bioactivity, altered glycosylation, and impurities, lacking pharmaceutically acceptable formulations that retain native bioactivity.
Innovation Solution
Purified lactoferrin is derived from unprocessed milk, maintaining native conformation and bioactivity, and formulated into various delivery formats for non-human subjects, including animals and pets, with specific formulations for topical, injectable, inhalable, and oral administration, and applications in wound care, reproductive health, and surface disinfection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lactoferrin is derived from processed milk sources, then production is feasible and scalable, but the lactoferrin undergoes denaturation, reduced bioactivity, altered glycosylation, and impurity contamination
Solution Approach 1:
The patent inverts the conventional approach by using unprocessed raw milk instead of processed milk as the starting material. This reversal prevents the denaturation and bioactivity loss that occur during traditional processing steps like pasteurization, concentration, and dialysis, while still enabling scalable production through direct purification from raw milk sources
Solution Approach 2:
The patent changes the processing parameters by eliminating heat treatment and chemical processing steps. The purification process operates under gentle conditions that maintain lactoferrin's native conformation and bioactivity, using pH-controlled precipitation and filtration rather than thermal or chemical denaturation methods
2Productivity
If lactoferrin is purified from processed milk, then production efficiency is improved, but impurities such as other proteins, enzymes, endotoxin, and prions remain
Solution Approach 1:
The patent applies preliminary action by performing pH-controlled precipitation and filtration steps before final purification. These preliminary steps remove bulk impurities including other proteins, enzymes, endotoxins, and prions, creating a cleaner starting material for subsequent purification steps and improving overall product safety
Solution Approach 2:
The patent selectively extracts lactoferrin from raw milk using pH-controlled precipitation at isoelectric point, followed by dialysis and ultrafiltration. This extraction process separates lactoferrin from other milk components and impurities, achieving high purity while maintaining bioactivity through gentle handling
3Quantity of substance
If conventional purification methods are used, then production cost is reduced, but lactoferrin bioactivity and iron-binding capacity are compromised
Solution Approach 1:
The patent employs simple, inexpensive purification steps such as pH adjustment, precipitation, and dialysis that can be performed with basic laboratory equipment. These disposable-like simple steps avoid the need for expensive chromatography resins or complex processing equipment, reducing production cost while preserving iron-binding capacity through gentle handling
Solution Approach 2:
The patent utilizes the inherent properties of lactoferrin, specifically its isoelectric point, to enable self-precipitation and self-purification. The lactoferrin naturally precipitates at its isoelectric point pH, allowing for easy separation from other milk components without requiring complex external purification systems, thereby reducing cost while maintaining bioactivity
