DMDC and Polyphosphate Synergy for Acetic Acid Bacteria Disinfection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for sterilizing and preserving beverages against acetic acid bacteria are inadequate, as conventional preservatives are not sufficiently strong and using high concentrations is economically and legally limited, while existing processes lack a synergistic effect against these bacteria.
Innovation Solution
The use of dimethyl dicarbonate (DMDC) in combination with cyclic polyphosphates, such as sodium hexametaphosphate, to effectively disinfect and preserve beverages without lauroyl ethyl arginate and trans-cinnamic acid, leveraging their synergistic action against acetic acid bacteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high concentrations of conventional preservatives are used to combat acetic acid bacteria, then the disinfection effectiveness is improved, but the economic cost increases and legal regulations are violated
Solution Approach 1:
The patent changes the chemical parameters by introducing dimethyl dicarbonate (DMDC) and cyclic polyphosphates with specific molecular structures and concentrations (DMDC: 1-500 ppm, polyphosphates: 10-1000 ppm), transforming the preservative system from conventional single agents to a synergistic combination with optimized parameter ranges that achieve effective disinfection at lower total concentrations
Solution Approach 2:
The patent creates a composite preservative system combining dimethyl dicarbonate and cyclic polyphosphates, where the interaction between these two chemically distinct substances produces a synergistic effect that enhances disinfection effectiveness beyond what either substance could achieve alone, allowing reduced individual concentrations
2Quantity of substance
If conventional preservatives are used at low concentrations to meet economic and legal requirements, then the cost and compliance issues are resolved, but the disinfection effectiveness against acetic acid bacteria is insufficient
Solution Approach 1:
The patent merges dimethyl dicarbonate and cyclic polyphosphates into a unified preservative system where both substances work together in the same beverage formulation, creating a synergistic partnership that achieves enhanced disinfection effectiveness at low combined concentrations, resolving the insufficiency of low-dose conventional preservatives
3Reliability
If multiple preservatives including lauroyl ethyl arginate and trans-cinnamic acid are used to achieve synergistic effect, then the disinfection effectiveness is improved, but the number of additives increases and complexity increases
Solution Approach 1:
The patent extracts and eliminates lauroyl ethyl arginate and trans-cinnamic acid from the preservative mixture, retaining only dimethyl dicarbonate and cyclic polyphosphates. This extraction removes unnecessary complexity while maintaining or enhancing disinfection effectiveness through the synergistic interaction of the remaining two substances
Solution Approach 2:
The patent demonstrates that dimethyl dicarbonate and cyclic polyphosphates can perform multiple functions: DMDC acts as both a sterilizing agent and a preservative, while cyclic polyphosphates provide both chelating activity and preservative function. This multi-functionality reduces the need for multiple specialized additives, simplifying the overall formulation
