Stable Coated Cinnamic Aldehyde for Animal Feed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cinnamic aldehyde-based products face stability issues when combined with animal feed, particularly due to aldimine condensation with protein feedstuffs, which existing encapsulation methods fail to adequately address.
Innovation Solution
A stable cinnamic aldehyde composition is developed using a core coated with an acidic layer as a chemical barrier and a polymer layer as a physical barrier, effectively inhibiting degradation by blocking aldimine condensation and physical contact with air and feed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical encapsulation barriers (palm fatty acid or glyceryl monostearate) are used to protect cinnamic aldehyde, then the product can be formulated for animal feed, but the encapsulation is insufficient to stabilize CIN once combined with protein feedstuff due to aldimine condensation
Solution Approach 1:
The patent applies composite materials by combining an acidic coating material (such as citric acid, tartaric acid, or ascorbic acid) with a polymer encapsulation material. The acidic layer is applied first to the cinnamic aldehyde core, followed by a polymer coating layer. This composite structure provides both chemical protection (acidic layer preventing aldimine condensation) and physical protection (polymer layer providing encapsulation), thereby achieving superior stability in protein-containing feedstuffs compared to physical encapsulation alone.
2Ease of manufacture
If no encapsulation is used, then the product formulation is simpler, but cinnamic aldehyde degrades rapidly when combined with protein feedstuff
Solution Approach 1:
The patent applies preliminary action by pre-coating the cinnamic aldehyde core with an acidic material before final encapsulation or feed mixing. This preliminary acidic coating creates a protective barrier that prevents aldimine condensation between the aldehyde group of CIN and amine groups in protein feedstuff. The acidic layer is applied in advance during the coating process, ensuring stability is established before the product encounters protein-containing feed ingredients.
3Object-affected harmful factors
If existing encapsulation methods are used, then some protection is provided, but they fail to inhibit aldimine condensation between CIN and amine function groups in protein feedstuff
Solution Approach 1:
The patent applies the intermediary principle by introducing an acidic coating material as a mediator between the cinnamic aldehyde core and the protein feedstuff. The acidic material (such as citric acid, tartaric acid, or ascorbic acid) forms a protective interface layer that chemically interferes with the aldimine condensation reaction between CIN and amine groups. This intermediary acidic layer prevents direct contact and reaction between the aldehyde and protein amine groups, thereby reliably inhibiting degradation.
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 composition exhibits superior stability, with less than 15% loss after 90 days of ambient storage, significantly outperforming commercially available products that rely solely on physical barriers.
Implementation Method 1
the encapsulation is not sufficient to stabilize the CIN once it is combined with any feed or feed raw materials that contain protein feedstuff... aldimine condensation between CIN and amine function groups in protein feedstuff
Implementation Method 2
creating a physical barrier, such as encapsulation or microencapsulation using palm fatty acid or glyceryl monostearate
