Taste-Improving Agents for Potassium Salt Substitutes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to effectively improve the unpleasant taste of potassium salts in foods and drinks without affecting the original flavor, limiting their use as sodium substitutes in reducing sodium content.
Innovation Solution
The use of quinic acid, spilanthol, or Allium plant extracts improves the taste of potassium salts by reducing metallic and acrid tastes while enhancing salt flavor, achieved through extraction and purification processes from tea leaves, coffee beans, and Spilanthes acmella plants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If potassium chloride is used to replace sodium chloride to reduce sodium content, then sodium intake is reduced, but unpleasant tastes such as metallic taste and acrid taste are produced
Solution Approach 1:
The patent introduces taste-improving agents as intermediary substances that mediate between potassium chloride and the human taste system. These agents (such as amino acids, nucleotides, organic acids, or their salts) interact with potassium chloride to mask or modify its unpleasant metallic and acrid tastes, making the salt substitute palatable while maintaining its sodium-reducing function
Solution Approach 2:
The patent creates composite seasoning compositions by combining potassium chloride with taste-improving agents. This composite material integrates the sodium-reducing benefit of potassium chloride with the taste-enhancing properties of the added agents, producing a unified seasoning that simultaneously achieves both health benefits and sensory acceptance
2Object-affected harmful factors
If inorganic salts or seasonings are added to enhance potassium chloride taste, then salt taste is enhanced, but unpleasant tastes unique to these materials are produced
Solution Approach 1:
The patent carefully controls the types and concentrations of taste-improving agents to optimize the taste profile. By adjusting parameters such as the specific amino acid used, its concentration, and the ratio to potassium chloride, the patent achieves enhanced salt taste while minimizing the introduction of new unpleasant tastes. The patent specifies precise compositional ranges to ensure desirable taste outcomes
3Object-affected harmful factors
If glutamate or nucleic acid-based gustatory substances are added to improve potassium chloride taste, then salt taste is enhanced, but the original flavor profile of foods or drinks is altered
Solution Approach 1:
The patent uses taste-improving agents that replicate or enhance the umami and salt sensations naturally associated with sodium chloride, rather than introducing completely different flavor profiles. By selecting agents like amino acids and nucleotides that mimic the gustatory properties of table salt, the patent enhances salt taste while preserving the original character and flavor identity of the food or beverage product

AI summary
The invention improves the unpleasant taste characteristic of potassium salts without affecting the original flavor of foods or drinks and increases the value of potassium salt as a salt substitute, in order to provide means and a salt composition for reducing sodium in foods and drinks. By adding one or more of the following: quinic acid or a quinic acid-containing composition, spilanthol or a spilanthol-containing plant extract or plant essential oil, or an Allium plant extract, to a potassium salt or a potassium salt-containing food or drink, the unpleasant tastes such as acrid taste and metallic taste characteristic of potassium salts are improved while the salt flavor and taste are augmented.
