Vitamin A Palmitate Extrudate Matrix for Oxygen-Stable Oral Dosing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Oral dosage forms containing vitamin A face challenges with stability, requiring extensive packaging due to oxygen sensitivity, leading to high costs and waste generation, while existing formulations like pellets and tablets are inefficient and costly.
Innovation Solution
The use of vitamin A palmitate embedded in a matrix of octenyl succinate starch and dextrin, optionally with α-tocopherol, β-tocopherol, and γ-tocopherol, to create stable, water-soluble or water-dispersible extrudates that reduce packaging needs and production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vitamin A is used in oral dosage forms, then nutritional value is provided, but stability deteriorates due to oxygen sensitivity requiring extensive packaging
Solution Approach 1:
A matrix comprising octenyl succinate starch and dextrin is introduced as an intermediary substance to embed vitamin A palmitate. This matrix acts as a protective mediator that reduces oxygen sensitivity and prevents direct exposure of vitamin A to degrading environmental factors, thereby stabilizing the vitamin without requiring extensive packaging systems.
Solution Approach 2:
The invention uses a composite material system where vitamin A palmitate is combined with octenyl succinate starch and dextrin in specific proportions (weight ratio from 2:1 to 1:2). This composite extrudate creates a stable formulation that maintains vitamin A integrity through the synergistic properties of the matrix components, eliminating the need for complex packaging.
2Reliability
If extensive packaging is used to protect vitamin A, then stability is improved, but cost increases and waste is generated
Solution Approach 1:
The octenyl succinate starch and dextrin matrix serves as a protective intermediary that internally stabilizes vitamin A, replacing the need for external protective packaging layers. This eliminates aluminum foil and other packaging materials that would otherwise be discarded after use, significantly reducing waste.
3Reliability
If conventional vitamin A sources are used, then basic nutritional function is achieved, but stability is insufficient requiring complex formulations
Solution Approach 1:
The invention changes the chemical form of vitamin A from common sources to vitamin A palmitate, and adjusts the physical-chemical parameters of the carrier system by using octenyl succinate starch and dextrin in specific ratios. These parameter changes fundamentally improve stability without requiring complex multi-component formulations or processing methods.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The extrudates exhibit high stability and recovery of vitamin A, with over 80% retention after 12 hours and up to 95% after 4 weeks, reducing waste and packaging costs.
Implementation Method 1
vitamin A palmitate binds to the OH groups of dextrin which helps prevent crystallization
Implementation Method 2
vitamin A palmitate is less susceptible to crystallization than vitamin A acetate within a matrix consisting essentially of octenyl succinate starch and dextrin

AI summary
Water-soluble or water-dispersible extrudates are provided which are formed of a matrix and vitamin A palmitate. The matrix comprises or consists of octenyl succinate starch and dextrin. Such water-soluble or water-dispersible extrudates have an excellent storage stability and may comprise further components such as other fat-soluble vitamins.
