Bacterial Composition Color Stability via Sodium Bicarbonate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bacterial compositions, particularly those containing Bifidobacterium animalis strain DSM15954, face challenges with color stability during storage, especially when exposed to moisture and high temperatures, leading to discoloration.
Innovation Solution
Incorporating sodium bicarbonate as a color stabilizer in the bacterial composition, which can be mixed with bacterial cells before or after adding a carrier, and then compressing the mixture to form a stable powder or tablet, effectively preventing or reducing discoloration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If bacterial composition is stored under high temperature and moisture conditions, then storage flexibility is improved, but color stability deteriorates due to discoloration
Solution Approach 1:
Sodium bicarbonate acts as an intermediary substance that mediates between the bacterial cells and the harmful effects of moisture and heat. It absorbs moisture through hygroscopic properties and neutralizes acidic byproducts, thereby protecting the bacterial composition from discoloration while allowing storage under varied temperature and humidity conditions
Solution Approach 2:
The invention changes the chemical parameters of the storage environment by introducing sodium bicarbonate, which alters the pH, moisture content, and chemical reactivity of the composition. This creates a protective microenvironment that prevents oxidative discoloration while maintaining bacterial viability during storage
2Stability of the object's composition
If sodium bicarbonate is added to bacterial composition, then color stability is improved, but formulation complexity increases
Solution Approach 1:
Sodium bicarbonate serves multiple functions simultaneously: it acts as a color stabilizer by preventing oxidative discoloration, serves as a buffer to neutralize acidic byproducts of bacterial metabolism, and provides hygroscopic properties to control moisture. This multi-functionality achieves color stability without requiring multiple separate additives, thereby limiting the increase in formulation complexity
