Sorbic Acid Precipitation in Beverage Syrup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sorbic acid commonly precipitates in beverage syrups, leading to cloudiness and sediment formation, which is undesirable for consumer acceptance and perceived spoilage, making it challenging to maintain the clarity and stability of preserved beverages.
Innovation Solution
Dissolving sorbic acid in an oil-based ingredient, such as potassium sorbate, which is then added to the syrup, preventing precipitation and maintaining clarity and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sorbic acid is introduced into concentrated syrup to provide preservative effect, then microbial spoilage is retarded, but precipitation and cloudiness occur
Solution Approach 1:
The patent uses an intermediary substance (such as a compatible solvent or carrier) to mediate between sorbic acid and the syrup matrix. This intermediary allows sorbic acid to be incorporated into the syrup without direct precipitation, maintaining both preservative effectiveness and solution clarity.
Solution Approach 2:
The patent employs parameter changes by adjusting pH, temperature, or concentration levels to control sorbic acid solubility. By modifying these parameters, the patent enables incorporation of sorbic acid at concentrations sufficient for preservation while preventing precipitation and maintaining syrup clarity.
2Duration of action of stationary object
If preservatives are added to syrup at high concentration to ensure preservation, then shelf life is extended, but precipitation and sediment formation increase
Solution Approach 1:
An intermediary carrier substance is introduced to transport high concentrations of sorbic acid through the syrup without causing precipitation. This intermediary allows achieving the desired shelf life extension while avoiding the formation of harmful precipitates and sediment.
Solution Approach 2:
The patent creates a composite solution by combining sorbic acid with compatible substances that form a stable mixture. This composite approach enables high preservative concentrations to be maintained in solution, extending shelf life without generating precipitation or sedimentation.
3Stability of the object's composition
If sorbic acid is dissolved in oil-based ingredient to prevent precipitation, then clarity is maintained, but additional ingredient complexity is introduced
Solution Approach 1:
The patent selects an oil-based ingredient that serves multiple functions: it acts as a carrier for sorbic acid, provides necessary flavor or functional properties, and maintains compatibility with other syrup components. This multi-functionality reduces the need for additional separate ingredients, thereby limiting the increase in overall complexity.
Solution Approach 2:
The patent utilizes the different solubility parameters of oil-based substances compared to aqueous syrups. By leveraging this parameter difference, sorbic acid can be dissolved in the oil-based ingredient to maintain clarity, while the oil component itself provides desirable beverage characteristics without requiring numerous additional additives.
