FAQs
How Tripotassium Citrate Helps Food Processors
For those handling sauces and dressings, this ingredient keeps emulsions stable—no more oil separating from vinegar in salad mixes. It cuts down on acidity spikes in tomato-based sauces, so batches taste consistent even when fruit ripeness varies. In baked goods, it stops fruit fillings from turning mushy during baking. Makers of processed cheeses rely on it to prevent gritty textures, ensuring spreads stay smooth on crackers or sandwiches. It also extends shelf life for refrigerated dips by slowing bacterial growth, reducing waste for small-scale producers. Easy to mix in, it works with both high-speed blenders and manual stirring, fitting into any kitchen setup without extra equipment hassle.
What is the typical assay (purity) and what standards does Tripotassium Citrate comply with?
Our Tripotassium Citrate typically has a purity of ≥99.0% (on anhydrous basis). It is manufactured to comply with major international pharmacopeial standards, including FCC (Food Chemicals Codex), USP-NF (United States Pharmacopeia), and BP/EP (British/European Pharmacopoeia), ensuring its suitability for food, nutraceutical, and pharmaceutical applications.
What is the solubility of Tripotassium Citrate and how does it affect formulation?
Tripotassium Citrate is highly soluble in water. Its solubility is approximately ~167 g/100 mL at 20°C. This high solubility ensures rapid and complete dissolution in aqueous systems, which is critical for preparing clear solutions in beverages, syrups, and liquid dosage forms without risk of sedimentation.
What is the role of Tripotassium Citrate as a buffering agent, and what is its typical pH in solution?
It acts as an effective alkalizing agent and pH buffer. A 1% aqueous solution typically has a pH between 7.5 and 9.0. Its high buffering capacity makes it ideal for precisely raising and stabilizing pH in applications ranging from urinary alkalization formulations to controlling acidity in food and beverage systems.
How does Tripotassium Citrate compare to Potassium Bicarbonate?
Compared to Potassium Bicarbonate, Tripotassium Citrate provides three potassium ions per molecule and offers superior buffering capacity due to its citrate moiety. It tends to have a less salty taste impact and dissolves more readily, making it preferred for liquid formulations and products where taste and rapid integration are critical.
Is Tripotassium Citrate compatible with common formulation ingredients?
Yes, it demonstrates excellent compatibility with most common excipients and active ingredients in food, supplement, and pharmaceutical matrices. However, as a rule of thumb, compatibility testing is recommended in final formulations, especially with highly acidic compounds or divalent cations (e.g., calcium, magnesium) where precipitation could occur under specific conditions.
