Meat Color Stabilization Using Carboxylic Acid Compositions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a significant need for safe and effective color-stabilizing agents to improve the appearance, shelf-life, and saleability of raw meat and raw meat-containing food products, as existing solutions struggle to predictably maintain color stability under varying oxygen conditions and are affected by rancidity, especially in meats with polyunsaturated fatty acids like salmon and poultry.
Innovation Solution
The use of combinations of carboxylic acid-containing compounds such as succinate, glutamate, citrate, malate, and pyruvate, which are safe for food use and can be manufactured at low cost, to create compositions that enhance color stability and reduce rancidity in raw meats, with specific ratios and forms of these compounds optimized for different oxygen environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If chemical agents with anti-oxidant and metmyoglobin-reducing capacities are used to maintain color stability under low-oxygen conditions, then color stability is improved, but the complexity of predicting effects under different conditions increases and reliability varies
Solution Approach 1:
The patent changes the chemical parameters by using specific carboxylic acid compounds (succinate, glutamate, citrate, malate, pyruvate) with defined concentrations and ratios. These parameter changes provide predictable color stability under varying oxygen conditions, resolving the reliability issue while maintaining color stability.
Solution Approach 2:
The patent employs composite compositions containing multiple carboxylic acid compounds working together. This composite approach enhances the reliability and predictability of color stability maintenance under different storage conditions, overcoming the limitations of single chemical agents.
2Illumination intensity
If high-oxygen packaging is used to maintain bright red color through oxymyoglobin, then color appearance is improved, but microbial action increases causing discolouration and rancidity
Solution Approach 1:
The carboxylic acid compounds act as intermediaries that protect the meat from microbial action and oxidation while allowing high-oxygen packaging to maintain bright color. These compounds mediate between the beneficial effect of oxygen exposure and the harmful effects of microbial growth and rancidity.
Solution Approach 2:
The patent converts the harmful effect of high-oxygen exposure (which causes microbial action and rancidity) into a beneficial outcome by using carboxylic acid compounds that prevent these harmful effects while maintaining the desirable bright red color from oxymyoglobin.
3Object-affected harmful factors
If low-oxygen packaging is used to reduce microbial action, then safety is improved, but metmyoglobin formation increases causing color deterioration
Solution Approach 1:
The carboxylic acid compounds serve as intermediaries that prevent metmyoglobin formation under low-oxygen conditions while allowing safe microbial control. These compounds enable the maintenance of both safety and color stability that would otherwise be in conflict.
Solution Approach 2:
The carboxylic acid compounds are applied preliminarily to the meat before packaging to prevent metmyoglobin formation. This preliminary action ensures color stability is maintained throughout low-oxygen storage while microbial action is controlled.
4Reliability
If multiple chemical additives are used to address different issues (color stability, anti-rancidity), then effectiveness is improved, but safety and manufacturing complexity increase
Solution Approach 1:
The carboxylic acid compounds exhibit multi-functionality, addressing color stability, anti-rancidity, and safety concerns simultaneously. This universal approach maintains effectiveness while simplifying manufacturing compared to using multiple separate additives.
Solution Approach 2:
The patent merges multiple preservation functions into a single group of carboxylic acid compounds. This combining approach maintains the effectiveness of addressing multiple issues (color stability, anti-rancidity) while improving ease of manufacture and safety by reducing the number of separate additives required.
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
These compositions effectively maintain the red color of raw meat, reduce rancidity, and improve storage stability, providing long-lasting color stabilization and oxidative stability under both low- and high-oxygen conditions, thereby enhancing the product's appearance and shelf-life.
Implementation Method 1
reduction of metmyoglobin to deoxymyoglobin is possible, but only if the necessary cofactors are available
Implementation Method 2
chemical agents having anti-oxidant and metmyoglobin-reducing capacities may be used to maintain colour and/or oxidative stability of the meat
Implementation Method 3
Rancidity arises due to the decomposition of fats and oils in a foodstuff, generally by oxidation and/or microbial action
