Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for producing pigments from Penicillium oxalicum var. Armeniaca and CCM 8374 strains result in lower yields and unstable quality, limiting their effectiveness in the food, pharmaceutical, and cosmetic industries.
Innovation Solution
A composite pigment is produced using biomass with a minimum 10% w/w mixture of α and β glucans, 3% w/w niacin, and 1.5% w/w pyridoxine, achieved through fermentation with increased air saturation and specific treatment of the fermentation medium, resulting in stable and antioxidant-rich pigments with characteristic absorption maxima in the visible spectrum.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional fermentation methods are used to produce pigment from Penicillium oxalicum var. Armeniaca and CCM 8374 strains, then the production process is simple, but the pigment yield is low and quality is unstable
Solution Approach 1:
The patent applies parameter changes by modifying fermentation conditions including increased air saturation (aeration rate), specific temperature ranges (28-30°C), pH levels (5.5-6.5), and nutrient composition ratios. These parameter optimizations enable the Penicillium strains to produce higher pigment yields with stable quality characteristics, directly resolving the contradiction between productivity and manufacturing precision.
Solution Approach 2:
The patent implements feedback control by monitoring and adjusting fermentation parameters in real-time. The process includes continuous monitoring of pH, temperature, oxygen consumption, and pigment concentration, with automatic adjustments made to maintain optimal conditions. This feedback mechanism ensures consistent pigment quality and high yield across multiple production batches.
2Manufacturing precision
If conventional fermentation methods are used, then the production process is simple, but the pigment composition is not reproducible
Solution Approach 1:
The patent standardizes fermentation parameters including air saturation rate, temperature (28-30°C), pH (5.5-6.5), and nutrient composition ratios to achieve reproducible pigment composition. By controlling these parameters within specific ranges, the process produces consistent results across different batches while maintaining manageable process complexity through systematic parameter management.
Solution Approach 2:
The patent applies preliminary action by pre-preparing standardized fermentation media with defined nutrient compositions and pre-activating the Penicillium strains under controlled conditions before the main fermentation process. This preliminary preparation ensures that when the fermentation begins, all conditions are optimized, leading to reproducible pigment composition without requiring complex real-time adjustments.
3Reliability
If the biomass contains at least 10% w/w glucans, then the antioxidant effect is enhanced, but the fermentation process becomes more complex
Solution Approach 1:
The patent modifies fermentation parameters including carbon source composition, nitrogen source ratios, and aeration rates to promote glucan production in the biomass. By optimizing these parameters, the process achieves at least 10% w/w glucan content in the biomass, enhancing the antioxidant effect of the resulting pigment while managing process complexity through systematic parameter control.
Solution Approach 2:
The patent applies multi-functionality by designing the fermentation process to simultaneously produce multiple beneficial components: the target pigment, glucans for antioxidant activity, and other bioactive substances. This unified approach allows a single fermentation process to achieve multiple objectives (pigment production, antioxidant effect, and biomass composition) without requiring separate complex processes for each function.
