Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Anthocyanins, beneficial for human health, are unstable during food processing and storage due to factors like processing methods, pH values, temperatures, light, oxygen, enzymes, and metal ions, leading to degradation and reduced shelf life, with existing methods like intramolecular or intermolecular copigmentation reactions, chemical modification, and bioengineering techniques having limitations.
Innovation Solution
A method involving the addition of starch to an aqueous hydrochloric acid solution with anthocyanins, followed by high hydrostatic pressure treatment and low-temperature storage to enhance the interaction between starch and anthocyanins, forming stable complexes that improve anthocyanin stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If anthocyanins are used in food processing and storage, then health benefits are provided, but stability is poor leading to degradation
Solution Approach 1:
The patent uses starch as an intermediary substance to form inclusion complexes with anthocyanins. The starch granules act as a protective matrix that encapsulates anthocyanin molecules, shielding them from degradation factors such as oxygen, light, and enzymes during food processing and storage, thereby significantly improving anthocyanin stability
Solution Approach 2:
The patent creates a composite system consisting of starch and anthocyanins in the form of inclusion complexes. This composite material combines the protective properties of starch with the functional benefits of anthocyanins, resulting in a stable formulation that maintains anthocyanin integrity under various processing conditions
2Reliability
If copigmentation reactions are used to maintain anthocyanin stability, then stability is improved, but the reaction rate is low
Solution Approach 1:
The patent replaces chemical copigmentation reactions with a physical inclusion complexation mechanism. Instead of relying on slow chemical reactions between anthocyanins and copigments, the method uses the physical encapsulation of anthocyanins within starch granules, which occurs rapidly and does not depend on chemical reaction kinetics
3Reliability
If chemical modification is used to improve anthocyanin stability, then stability is improved, but residual organic reagents remain
Solution Approach 1:
The patent uses native starch as a simple, natural, and biodegradable protective matrix that requires no chemical modification. The starch granules provide effective protection through physical inclusion alone, eliminating the need for chemical reagents and avoiding the problem of residual organic substances in the final product
4Reliability
If macromolecules are used to form complexes with anthocyanins, then stability is improved, but large-molecular-weight substances cannot enter starch granules efficiently
Solution Approach 1:
The patent utilizes the ability of starch granules to undergo structural changes under specific conditions (such as heating and cooling cycles) that temporarily open the granule structure, allowing anthocyanins to penetrate inside. After cooling, the granules re-close, trapping anthocyanins within the protected interior, thereby achieving high interaction efficiency

Function Achieved in This Case
The method significantly extends the shelf life and improves the quality of anthocyanin-rich foods by enhancing the interaction efficiency between starch and anthocyanins, maintaining their stability and physiological benefits.
Implementation Method 1
subjecting the system to high hydrostatic pressure treatment
Implementation Method 2
treating the resulting system at a certain high hydrostatic pressure condition to enable the starch to be gelatinized
Implementation Method 3
anthocyanins can enter starch granules and interact with double helix molecular chains of amylose inside the starch granules, thereby protecting anthocyanins
Implementation Method 4
subjecting the mixture obtained from the high hydrostatic pressure treatment to low-temperature storage

AI summary
The present invention relates to the technical field of food science and engineering, and specifically to a method for improving the stability of anthocyanins. In the method, a starch and an anthocyanin are mixed in an aqueous solution of hydrochloric acid, treated at a certain high hydrostatic pressure condition to enable the starch to be gelatinized and to interact with the anthocyanin, and then stored at a certain temperature, so that interaction between the anthocyanin and the starch is further enhanced to form a complex. The method can improve the stability of anthocyanins, which helps to improve the quality of products and extend the shelf life of products.
