Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods to protect foodstuffs and agricultural products from decay often involve the use of toxic substances, which are being phased out due to environmental concerns, and result in significant losses of up to 30-40%.
Innovation Solution
The use of performic acid compositions to contact edible matter or its substrates, achieving a 10,000- to 100,000-fold reduction in pathogens and microorganisms within one minute at room temperature, with minimal residue and environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If toxic substances are used to protect foodstuffs from decay, then protection effectiveness is improved, but environmental harm increases
Solution Approach 1:
The patent changes the chemical parameters by using performic acid (a peroxide derivative) instead of traditional toxic preservatives. Performic acid decomposes into formic acid and oxygen, eliminating toxic residues while maintaining antimicrobial effectiveness through oxidation mechanisms, thus resolving the contradiction between protection effectiveness and environmental harm.
Solution Approach 2:
The patent converts the potentially harmful effect of strong oxidants into a beneficial outcome. Performic acid's oxidative capability, which could be considered harmful to microorganisms, is harnessed as a protective mechanism that kills pathogens while decomposing into benign substances (formic acid and oxygen), thereby converting a potentially harmful chemical action into a beneficial protective effect with minimal environmental impact.
2Object-affected harmful factors
If conventional preservatives are applied, then microbial contamination is reduced, but toxic residues remain
Solution Approach 1:
The patent employs performic acid as a disposable, self-decomposing agent. Unlike conventional preservatives that leave persistent toxic residues, performic acid rapidly decomposes into formic acid and oxygen after performing its antimicrobial function. This disposable characteristic eliminates the problem of toxic residue accumulation while maintaining effective microbial control during the treatment period.
Solution Approach 2:
The patent utilizes performic acid's strong oxidizing properties to accelerate the destruction of microorganisms. The oxidative mechanism rapidly kills pathogens by damaging their cellular structures, achieving effective microbial contamination reduction. The oxidation process is so efficient that the agent decomposes quickly after use, preventing residue problems associated with conventional preservatives.
3Reliability
If performic acid is applied at high concentration, then pathogen reduction is improved, but treatment time increases
Solution Approach 1:
The patent applies performic acid at concentrations that provide more than sufficient pathogen reduction (excessive action). By using higher concentrations than the minimum effective level, the treatment achieves rapid and complete microbial elimination within one minute. This excessive action approach ensures that even in challenging conditions, the pathogen reduction target is met quickly, resolving the contradiction between reduction effectiveness and treatment time.
